Description

Technical Field

[0001] This invention relates to the field of fuel saver technology, and more particularly to a fully automatic fuel saver for automobiles. Background Technology

[0002] In current technology, gasoline-powered engines suffer from several problems. Standard power supplies cannot provide sufficient energy to the ignition coils, resulting in an incomplete combustion of gasoline, high combustion chamber temperatures, and the accumulation of carbon deposits. This can worsen over time, leading to piston ring seizure and ultimately severe oil burning and cylinder scoring. Existing fuel-saving devices address these issues by: ionizing water into hydrogen and oxygen, which are then delivered to the engine cylinders for combustion; ionizing air into ozone using the car's electrical system to increase oxygen supply; using a built-in capacitor connected to the car's power source, such as the cigarette lighter, to stabilize the current and assist fuel supply; influencing fuel flow through magnetic devices; and stabilizing the pulse voltage of the car's electrical circuits using variable frequency voltage regulation technology, storing the charge to extend the lifespan of electronic components and improve fuel and component control, thereby achieving fuel savings.

[0003] Chinese Patent Publication No. CN1673515A discloses an electronic fuel saver, comprising a DC power input circuit, a voltage regulator circuit, a microcontroller (8), an amplifier circuit, and an output circuit, all housed within a sealed housing (3). The feature is that the vehicle's DC power supply is output from the DC power input circuit to the voltage regulator circuit, which then regulates the voltage and provides it to the microcontroller (8) and the amplifier circuit as their respective operating power. The input terminal of the amplifier circuit is connected to the output terminal of the microcontroller (8). The current signal output by the microcontroller (8), varying at different frequencies, is amplified by the amplifier circuit and finally output through the two output wires (5) of the output circuit. Therefore, the electronic fuel saver suffers from several problems: incomplete combustion of carbon deposits in the fuel cylinder leading to increased exhaust pollution; increased fuel cylinder fatigue due to the high power at ignition, resulting in unstable fuel saver connection; and decreased inductance due to insulation aging caused by ignition coil heating. Summary of the Invention

[0004] Therefore, the present invention provides a fully automatic control automotive fuel saver to overcome the problems of the prior art, such as increased exhaust pollution due to incomplete combustion of carbon deposits in the fuel cylinder, increased fatigue of the fuel cylinder due to the high power at the moment of ignition, resulting in unstable fuel saver connection, and decreased inductance due to insulation aging caused by heating of the ignition coil.

[0005] To achieve the above objectives, the present invention provides a fully automatic fuel-saving device for automobiles, comprising a housing, and further comprising:

[0006] A voltage drive module, which is disposed inside the housing, is used to provide fuel-saving ignition voltage to the ignition coil. It includes a circuit board body, a signal conversion component disposed on the circuit board body to convert the output current signal of the power supply into a voltage signal, and a booster component connected to the signal conversion component to amplify the voltage signal.

[0007] The detection module includes a temperature sensor connected to the ignition coil to detect the temperature of the ignition coil and a torque sensor connected to the hydraulic cylinder to detect the instantaneous starting torque of the hydraulic cylinder.

[0008] A control module, which is connected to the voltage drive module and the detection module respectively, is used to determine whether to adjust the output power of the booster component based on the torque change of the hydraulic cylinder, or to adjust the input voltage of the voltage drive module based on the voltage fluctuation amplitude of the receiving component.

[0009] Furthermore, without adjusting the output power of the booster assembly, the duration of the output voltage of the booster assembly is adjusted according to the temperature change of the ignition coil, or the capacitance of the booster assembly is adjusted according to the voltage of the ignition coil.

[0010] Furthermore, the signal conversion component includes:

[0011] The grounding sensor is connected to the power supply and is used to receive the voltage difference between the ground wire and the positive terminal of the power supply and to shield the electromagnetic interference of electronic components in the vehicle body.

[0012] An input flow meter, connected in series with the grounding sensor, is used to detect the voltage between the grounding wire and the positive terminal of the power supply when the vehicle is started.

[0013] A receiving resistor, connected in series with the input flow meter, is used to detect the input voltage of the voltage drive module.

[0014] Furthermore, the booster assembly includes:

[0015] An electrolytic capacitor, connected to the receiving resistor, is used to store electrical energy input to the voltage drive module;

[0016] A diode, which is connected to the electrolytic capacitor, is used to maintain a constant output voltage of the electrolytic capacitor;

[0017] A voltage feedback amplifier, connected to the diode, is used to amplify the output voltage of the voltage drive module.

[0018] Further, the housing includes:

[0019] The first packaging body is positioned above the main body of the circuit board to provide impact protection for the circuit components on the main body of the circuit board.

[0020] The second packaging body, which is fastened to the first packaging body, is used to protect the connecting lines on the circuit board body from impact.

[0021] Furthermore, the voltage drive module also includes:

[0022] The first connection terminal is connected to the grounding sensor to transmit the voltage signal output by the power supply to the grounding sensor.

[0023] The second connection terminal is connected to the receiving resistor to transmit the input current of the voltage drive module to the receiving resistor;

[0024] The third connection terminal group is connected to the voltage feedback amplifier to transmit the output voltage of the voltage drive module to the ignition coil. The third connection terminal group includes a plurality of third connection terminals, the number of which is equal to the number of ignition coils.

[0025] Furthermore, the control module is connected to the torque sensor and the diode respectively to periodically acquire the change in instantaneous torque of the cylinder during ignition. If the change in instantaneous torque is greater than a preset second change, it is determined that the fatigue level of the cylinder does not meet the requirements, and the output power of the booster assembly is reduced.

[0026] The output power is positively correlated with the change in instantaneous torque.

[0027] Furthermore, the control module is connected to the torque sensor and the booster assembly respectively, and is used to determine that the stability of the input voltage of the voltage drive module does not meet the requirements when the instantaneous torque change of the hydraulic cylinder is greater than a preset first change and less than or equal to a preset second change, and to increase the output voltage provided by the power supply to the voltage drive module.

[0028] The output voltage is determined based on the difference between the change in instantaneous torque and the preset first change. The change in instantaneous torque is the difference between the starting instantaneous torque of the cylinder detected at the beginning of a single detection cycle and the starting instantaneous torque of the cylinder detected at the end of the single detection cycle.

[0029] Furthermore, the control module is connected to the temperature sensor and the booster assembly respectively, and is used to acquire the temperature change of the ignition coil during the release of high-voltage current when the fatigue level of the hydraulic cylinder and the stability of the input voltage of the voltage drive module meet the requirements. If the temperature change is greater than a preset second temperature change, it is determined that the mechanical properties of the insulation material of the ignition coil do not meet the requirements, and the output voltage duration of the booster assembly is increased.

[0030] The duration of the output voltage is positively correlated with the temperature change; the temperature change of the ignition coil during the release of high-voltage current is the difference between the temperature of the ignition coil when releasing high-voltage current and the temperature of the ignition coil before ignition.

[0031] Furthermore, the control module is connected to the temperature sensor and the electrolytic capacitor respectively, and is used to preliminarily determine that the induction intensity of the ignition coil does not meet the requirements when the temperature change is greater than the preset first temperature change and less than or equal to the preset second temperature change, and to obtain the error between the induced voltage of the ignition coil and the preset induced voltage of the ignition coil under the corresponding output power.

[0032] If the error exceeds a preset error, the engine is determined to be in an overload operation state, and the capacitance of the electrolytic capacitor is increased.

[0033] The error is the absolute value of the difference between the induced voltage of the ignition coil and the preset induced voltage of the ignition coil at the corresponding output power; the increase in the electrolytic capacitor is positively correlated with the error.

[0034] Furthermore, the control module is connected to the input flow meter and the receiving resistor respectively to obtain the voltage signal when the vehicle starts. If the voltage signal is not within the standard voltage signal parameters, the amplification ratio of the voltage feedback amplifier is adjusted accordingly based on the positive or negative value of the change between the voltage signal and the standard voltage signal parameters.

[0035] Compared with the prior art, the beneficial effects of the present invention are as follows: The device of the present invention, by setting up a voltage drive module, a detection module, and a control module, detects electrical signals through a signal conversion component to accurately adjust the parameters of the booster component. Incomplete combustion of the oil in the cylinder leads to carbon deposits, increasing exhaust pollution and causing piston ring seizure, resulting in engine failure. Increasing the ignition power ensures complete combustion of the oil. Since ignition power exceeding the power supply voltage causes a large impact force on the cylinder, increasing cylinder fatigue and altering cylinder torque, adjusting the output power reduces the impact force at ignition on the fatigued cylinder. Impacts: By monitoring the combustion status of the fuel in real time and dynamically adjusting the ignition power according to the combustion conditions, the fuel is ensured to burn under optimal conditions, thereby reducing carbon deposits, lowering exhaust pollution, avoiding unnecessary impact on the cylinder due to excessive ignition power, extending the service life of the cylinder, and improving engine stability; The torque generated by a fatigued cylinder during ignition causes a decrease in the stability of the voltage drive module connection position, leading to voltage fluctuations in the voltage drive module. By adjusting the input voltage, the stability of the voltage drive module's operation and monitoring is improved, thereby increasing the monitoring accuracy of the voltage drive module and further improving combustion efficiency.

[0036] Furthermore, the device of the present invention, by setting a grounding sensor, an input flow meter, and a receiving resistor, ensures that the voltage of the electrolytic capacitor is higher than the voltage of the power supply, so that the voltage of the ignition coil is higher than the power supply voltage when the engine is ignited, thereby achieving complete combustion of the fuel; the grounding sensor can monitor the vehicle status in real time and shield the electromagnetic signal from interfering with the voltage drive module, improving the stability of ignition.

[0037] Furthermore, the device of the present invention, by setting up an electrolytic capacitor, a diode, and a voltage feedback amplifier, and by setting up a combination of a receiving resistor and an electrolytic capacitor, is used to stabilize and regulate the voltage and to accurately transmit signals, preventing ignition instability caused by voltage fluctuations; when the voltage of the electrolytic capacitor is higher than the power supply voltage, the ignition coil can generate a stronger electric spark, thereby improving the combustion efficiency of the fuel; the diode utilizes the reverse breakdown characteristic of the PN junction, and when the reverse voltage reaches a certain value, it can keep the current changing within a large range while the voltage remains basically constant, thereby achieving a voltage regulation function. By stabilizing the output voltage, providing overvoltage protection, and improving circuit stability, the operational stability of the voltage drive module is improved.

[0038] Furthermore, the device of the present invention protects the circuit board body by setting a first packaging body and a second packaging body, ensuring that the circuit board body can work normally under various harsh environments, preventing the connection wires from loosening due to vehicle vibration and thus causing the connection wires to fall off, and preventing short circuits or corrosion caused by rainwater or moisture intrusion, thereby achieving physical protection of the circuit board body and improving the reliability of electrical connections.

[0039] Furthermore, the device of the present invention reduces the output power of the voltage drive module when the fatigue level of the hydraulic cylinder does not meet the requirements by setting a preset second change amount. Since the high voltage at the moment of ignition causes the oil to burn completely and generate an impact force on the hydraulic cylinder, it accelerates the fatigue of the hydraulic cylinder and increases the starting torque of the hydraulic cylinder. If the output power continues to increase, it will damage the hydraulic cylinder or reduce the stability of the engine. By reducing the output power, the engine load is further reduced, so as to achieve the purpose of long-term fuel consumption reduction.

[0040] Furthermore, the device of the present invention determines the stability of the input voltage and then adjusts the input voltage accordingly. Because the large torque during ignition reduces the stability of the vehicle body, it leads to instability in the connection position between the voltage drive module and the power supply, resulting in fluctuations in the input voltage. These voltage fluctuations reduce the accuracy of electrical signal detection in the voltage drive module. By increasing the input voltage, the connection line between the voltage drive module and the power supply is heated and softened, thereby reducing the instability caused by the strong mechanical properties of the connection position. This improves the continuity and stability of the power supply.

[0041] Furthermore, the device of the present invention sets a preset second temperature change amount. Due to the high-power ignition conditions, the ignition coil operating temperature is too high, causing the insulation layer of the ignition coil to age. The aging of the attached insulation layer increases the resistance of the ignition coil, which in turn increases the temperature and resistance of the third connection terminal group. By increasing the output voltage duration of the booster component, the aging degree of the insulation layer under continuous temperature rise and the current continuity during ignition are accelerated to overcome the current fluctuation caused by the temperature rise of the third connection terminal, thereby increasing the stability of the engine.

[0042] Furthermore, the device of the present invention sets a preset error amount. Due to the increase in temperature of the ignition coil, the induction capability of the secondary coil decreases. After the voltage drive module detects this situation, it will produce an error in judging the ignition conditions of the ignition coil. By increasing the capacitance of the electrolytic capacitor, the influence of voltage fluctuations caused by excessive engine load on the turbocharger component is reduced, thereby improving the engine's operational stability and fuel efficiency.

[0052] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The figures shown are, respectively, a schematic diagram of the overall structure of the fully automatic controlled car fuel saver according to an embodiment of the present invention, a schematic diagram of the voltage drive module structure, an overall structural block diagram, and a structural block diagram of the voltage drive module. The present invention provides a fully automatic controlled car fuel saver, including a housing 9, and further comprising:

[0053] A voltage drive module, which is disposed inside the housing 9, drives the ignition module by providing a fuel-saving ignition voltage. It includes a circuit board body 1, a signal conversion component disposed on the circuit board body 1 for converting the output current signal of the power supply into a voltage signal, and a booster component connected to the signal conversion component for amplifying the voltage signal.

[0054] The detection module includes a temperature sensor connected to the ignition coil to detect the temperature of the ignition coil and a torque sensor connected to the hydraulic cylinder to detect the instantaneous starting torque of the hydraulic cylinder.

[0055] A control module, which is connected to the voltage drive module and the detection module respectively, is used to determine whether to adjust the output power of the booster component based on the torque change of the hydraulic cylinder, or to adjust the input voltage of the voltage drive module based on the voltage fluctuation amplitude of the receiving component.

[0056] Furthermore, without adjusting the output power of the booster assembly, the duration of the output voltage of the booster assembly is adjusted according to the temperature change of the ignition coil, or the capacitance of the booster assembly is adjusted according to the voltage of the ignition coil.

[0057] Specifically, embodiments of the control module include MCU microcontrollers and PLC controllers, with the preferred embodiment being an MCU microcontroller.

[0058] In implementation, the device of this invention, by setting up a voltage drive module, a detection module, and a control module, detects electrical signals through a signal conversion component to accurately adjust the parameters of the booster component. Incomplete combustion of the fuel in the cylinder leads to carbon buildup, increasing exhaust pollution and causing piston ring seizure, resulting in engine malfunction. Increasing the ignition power ensures complete combustion of the fuel. Since exceeding the power supply voltage causes a large impact force on the cylinder, increasing cylinder fatigue and altering its torque, adjusting the output power reduces the further impact of the instantaneous ignition impact on the fatigued cylinder. Real-time... The system monitors the combustion status of the hydraulic fluid and dynamically adjusts the ignition power based on the combustion conditions to ensure optimal combustion. This reduces carbon buildup, lowers exhaust emissions, avoids unnecessary impacts on the hydraulic cylinders caused by excessive ignition power, extends cylinder lifespan, and improves engine stability. Furthermore, the torque generated during ignition in fatigued cylinders leads to decreased stability at the voltage drive module connection point, causing voltage fluctuations. Adjusting the input voltage improves the stability of the voltage drive module's operation and monitoring, thereby enhancing its monitoring accuracy and further improving combustion efficiency.

[0059] Specifically, the signal conversion component includes:

[0060] Grounding sensor 5 is connected to the power supply and is used to receive the voltage difference between the grounding wire and the positive terminal of the power supply and to shield the electromagnetic interference of electronic components in the vehicle body.

[0061] An input flow meter 6 is connected in series with the grounding sensor 5 to detect the voltage between the grounding wire and the positive terminal of the power supply when the vehicle is started.

[0062] The receiving resistor 4 is connected in series with the input flow meter 6 to detect the input voltage of the voltage drive module.

[0063] In practice, the device of the present invention, by setting a grounding sensor 5, an input flow meter 6, and a receiving resistor 4, ensures that the voltage of the electrolytic capacitor 2 is higher than the voltage of the power supply, so that the voltage of the ignition coil is higher than the power supply voltage when the engine is ignited, thereby achieving complete combustion of the fuel; the grounding sensor 5 can monitor the vehicle status in real time and shield the electromagnetic signal from interfering with the voltage drive module, thereby improving the stability of ignition.

[0064] Specifically, the booster assembly includes:

[0065] Electrolytic capacitor 2, which is connected to the receiving resistor 4, is used to store electrical energy input to the voltage drive module;

[0066] Diode 8 is connected to the electrolytic capacitor 2 to maintain a constant output voltage of the electrolytic capacitor 2;

[0067] The voltage feedback amplifier 3, which is connected to the diode 8, is used to amplify the output voltage of the voltage drive module.

[0068] Specifically, the voltage feedback amplifier 3 can be selected from operational amplifier voltage chips or operational amplifiers, and the preferred embodiment of the voltage feedback amplifier 3 is an operational amplifier.

[0069] Specifically, diode 8 can be selected from frequency-regulating constant voltage diode 8, low-voltage voltage regulator diode 8, and unipolar voltage regulator diode 8. The preferred embodiment of diode 8 is frequency-regulating constant voltage diode 8.

[0070] In implementation, the device of the present invention uses an electrolytic capacitor 2, a diode 8, and a voltage feedback amplifier 3. The combination of the receiving resistor 4 and the electrolytic capacitor 2 is used to stabilize and regulate the voltage and to transmit signals accurately, preventing ignition instability caused by voltage fluctuations. When the voltage of the electrolytic capacitor 2 is higher than the power supply voltage, the ignition coil can generate a stronger electric spark, thereby improving the combustion efficiency of the fuel. The diode 8 utilizes the reverse breakdown characteristic of the PN junction to maintain a relatively constant voltage while the current varies over a wide range when the reverse voltage reaches a certain value, thereby achieving voltage regulation. By stabilizing the output voltage, providing overvoltage protection, and improving circuit stability, the stability of the voltage drive module is improved.

[0071] Specifically, the housing 9 includes:

[0072] The first packaging body 91 is disposed above the circuit board body 1 to provide anti-collision protection for the circuit components on the circuit board body;

[0073] The second packaging body 92 is fastened to the first packaging body 91 to provide anti-collision protection for the connection lines on the circuit board body 1.

[0074] Specifically, the first packaging body 91 and the second packaging body 92 are made of plastic, and the first packaging body 91 and the second packaging body 92 together constitute the outer packaging body.

[0075] Specifically, the circuit board body 1 is fixed between the first packaging body 91 and the second packaging body 92 by an encapsulating liquid. The encapsulating liquid can be epoxy resin, phenolic resin, or polyurethane resin, and is mixed with curing agents and additives.

[0076] Specifically, when encapsulating the circuit board body 1, encapsulation liquid is first laid on the bottom of the second packaging body 92, then the circuit board body 11 is placed on top, and then encapsulation liquid is laid on top again to completely submerge the circuit board body 11. The first packaging body 91 is then fastened and left to cure.

[0077] In practice, the device of the present invention protects the circuit board body 1 by setting a first packaging body 91 and a second packaging body 92, ensuring that the circuit board body 1 can work normally under various harsh environments, preventing the connection wires from loosening due to vehicle vibration and thus causing the connection wires to fall off, and preventing short circuits or corrosion caused by rainwater or moisture intrusion, thereby achieving physical protection of the circuit board body 1 and improving the reliability of electrical connections.

[0078] Specifically, the voltage drive module further includes:

[0079] The first connection terminal 51 is connected to the grounding sensor 5 to transmit the voltage signal output by the power supply to the grounding sensor.

[0080] The second connection terminal 41 is connected to the receiving resistor 4 to transmit the input current of the voltage drive module to the receiving resistor;

[0081] The third connection terminal group 7 is connected to the voltage feedback amplifier 3 to transmit the output voltage of the voltage drive module to the ignition coil. The third connection terminal group 7 includes a plurality of third connection terminals 71, the number of which is equal to the number of ignition coils.

[0082] Specifically, the control module is connected to the torque sensor and the diode respectively, to periodically acquire the instantaneous torque change of the cylinder during ignition. If the instantaneous torque change is greater than a preset second change, the fatigue level of the cylinder is determined to be unsatisfactory, and the output power of the booster assembly is reduced.

[0083] The output power is positively correlated with the change in instantaneous torque.

[0084] Specifically, the output power of the booster assembly is the ratio of the square of the output voltage of the voltage feedback amplifier to the resistance of the ignition coil.

[0085] Specifically, the output power of the booster component is adjusted by regulating the conduction level of the diodes.

[0086] Specifically, the general range of the second change is [10Nm, 14Nm].

[0087] Preferably, the second variation amount is 12 Nm in the preferred embodiment.

[0088] In practice, if the difference between the instantaneous torque change and the preset second change is within 1 Nm, the output power of the booster component decreases by 2 W. If the difference between the instantaneous torque change and the preset second change exceeds 1 Nm, the output power of the booster component decreases by 4 W for every 1 Nm difference. For example, if the instantaneous torque change is 14 Nm and the current output power of the booster component is 128 W, then the output power of the booster component decreases to 128 - 2 - 4 = 122 W.

[0089] In practice, the device of the present invention determines the stability of the input voltage and then adjusts the input voltage accordingly. Due to the large torque during ignition, the vehicle body stability is reduced, which in turn leads to instability in the connection position between the voltage drive module and the power supply, resulting in fluctuations in the input voltage. Voltage fluctuations reduce the accuracy of electrical signal detection in the voltage drive module. By increasing the input voltage, the connection line between the voltage drive module and the power supply is heated and softened, thereby reducing the instability caused by the strong mechanical properties of the connection position, thus improving the continuity and stability of power supply.

[0090] Specifically, the control module is connected to the torque sensor and the booster assembly, respectively. When the instantaneous torque change of the hydraulic cylinder is greater than a preset first change but less than or equal to a preset second change, the module determines that the stability of the input voltage of the voltage drive module does not meet the requirements, and increases the output voltage supplied to the voltage drive module by the power supply.

[0091] The output voltage is determined based on the difference between the change in instantaneous torque and the preset first change. The change in instantaneous torque is the difference between the starting instantaneous torque of the cylinder detected at the beginning of a single detection cycle and the starting instantaneous torque of the cylinder detected at the end of the single detection cycle.

[0092] Specifically, the general range of the number of detections in a single cycle is [14 times, 20 times], and the preferred embodiment of the number of detections in a single cycle is 18 times.

[0093] Specifically, the general range of the first change is [5Nm, 8Nm].

[0094] Preferably, the preferred embodiment of the preset first change amount is 6 Nm.

[0095] In practice, if the difference between the instantaneous torque change and the preset first change is within 1 Nm, the output voltage increases by 0.4 V. If the difference between the instantaneous torque change and the preset first change exceeds 1 Nm, the output voltage increases by 0.6 V for every 1 Nm difference. For example, if the instantaneous torque change is 8 Nm and the current output voltage is 12 V, then the output voltage increases to 12 V + 0.4 V + 0.6 V = 13 V.

[0096] Specifically, the typical range of the duration of the output voltage increase is [3s, 6s], and the preferred embodiment of the duration of the output voltage increase is 4s.

[0097] In practice, the device of the present invention sets a preset second temperature change amount. Due to the high power ignition conditions, the ignition coil operating temperature is too high, causing the insulation layer of the ignition coil to age. The aging of the attached insulation layer increases the resistance of the ignition coil, which in turn increases the temperature and resistance of the third connection terminal group 7. By increasing the output voltage duration of the booster component, the aging degree of the insulation layer under continuous temperature rise and the current continuity during ignition are accelerated to overcome the current fluctuation caused by the temperature rise of the third connection terminal 71, thereby increasing the stability of the engine.

[0098] Specifically, the control module is connected to the temperature sensor and the booster assembly, respectively. When the fatigue level of the hydraulic cylinder and the stability of the input voltage of the voltage drive module meet the requirements, it acquires the temperature change of the ignition coil during the release of high-voltage current. If the temperature change exceeds a preset second temperature change, it determines that the mechanical properties of the insulation material of the ignition coil do not meet the requirements, and increases the duration of the output voltage of the booster assembly.

[0099] The duration of the output voltage is positively correlated with the temperature change; the temperature change of the ignition coil during the release of high-voltage current is the difference between the temperature of the ignition coil when releasing high-voltage current and the temperature of the ignition coil before ignition.

[0100] Specifically, the general range of the preset second temperature change is [65℃, 80℃].

[0101] Preferably, the preferred embodiment of the preset second temperature change is 70°C.

[0102] In practice, when the difference between the temperature change and the preset second temperature change is within 2℃, the output voltage duration increases by 0.1s. When the difference between the temperature change and the preset second temperature change exceeds 2℃, the output voltage duration increases by 0.05s for every 1℃ increase. For example, if the temperature change is 73℃ and the current output voltage duration is 0.2s, then the output voltage duration increases to 0.2s + 0.1s + 0.05s = 0.35s.

[0103] In practice, the device of the present invention sets a preset error amount. Due to the increase in temperature of the ignition coil, the induction capability of the secondary coil decreases. After the voltage drive module detects this situation, it will produce an error in judging the ignition conditions of the ignition coil. By increasing the capacitance of the electrolytic capacitor 2, the influence of voltage fluctuations caused by excessive engine load on the turbocharger component is reduced, thereby improving the engine's operating stability and fuel efficiency.

[0104] Specifically, the control module is connected to the temperature sensor and the electrolytic capacitor respectively, and is used to initially determine that the induction intensity of the ignition coil does not meet the requirements when the temperature change is greater than a preset first temperature change and less than or equal to a preset second temperature change, and to obtain the error between the induced voltage of the ignition coil and the preset induced voltage of the ignition coil under the corresponding output power.

[0105] If the error exceeds a preset error, the engine is determined to be in an overload operation state, and the capacitance of the electrolytic capacitor is increased.

[0106] The error is the absolute value of the difference between the induced voltage of the ignition coil and the preset induced voltage of the ignition coil at the corresponding output power; the increase in the electrolytic capacitor is positively correlated with the error.

[0107] Specifically, the general range of the preset error value is [2.2V, 2.6V].

[0108] Preferably, the preferred embodiment of the preset error amount is 2.4V.

[0109] In practice, the device of the present invention sets a preset error amount. As the temperature of the ignition coil increases, the induction capability of the secondary coil decreases. After the voltage drive module detects this situation, it will make an error in judging the ignition conditions of the ignition coil. By indicating the engine overload state, the engine load is reduced, the internal structure of the ignition coil is stabilized, and the engine operation stability and fuel efficiency are improved.

[0110] Specifically, the control module is connected to the input flow meter and the receiving resistor respectively to obtain the voltage signal when the vehicle starts. If the voltage signal is not within the standard voltage signal parameters, the amplification ratio of the voltage feedback amplifier is adjusted accordingly based on the positive or negative value of the change between the voltage signal and the standard voltage signal parameters.

[0111] Specifically, when the change in the electrical signal parameters is the difference between the electrical signal parameters and the standard electrical signal parameters, if the difference is positive, the amplification ratio of the voltage feedback amplifier 3 is reduced; if the difference is negative, the amplification ratio of the voltage feedback amplifier 3 is increased.

[0112] Specifically, by using the fully automatic control fuel saver for automobiles described in this invention, engine power is increased by about 30% to 40%, and fuel consumption is reduced by 30% to 40%. For example, when a car runs normally for about 3,000 to 5,000 kilometers, the carbon deposits in the combustion chamber can be burned off to reduce exhaust emissions.
