Description

Technical Field

[0001] The present invention belongs to the technical field of ignition angle adjustment equipment, and in particular relates to an online real-time detection ignition angle adjustment device and a use method thereof. Background Art

[0002] During engine operation, precise control of the ignition angle (ignition advance angle) is crucial to engine performance. Traditional ignition systems, such as mechanical contact types, find it difficult to dynamically adjust the ignition angle according to the real-time operating conditions of the engine, and ignition often occurs too early, just in time, or too late: when ignition is too early, the piston ignites before reaching the top dead center. The kinetic energy generated by the combustion and explosion will form a force opposite to the direction of engine rotation, resulting in an imbalance in rotational kinetic energy and the engine being unable to operate effectively; when ignition is too late, the piston ignites after passing the top dead center, and the combustion kinetic energy cannot be effectively converted into rotational energy, resulting in insufficient engine power output and discontinuous operation; only when the ignition timing is exactly when the piston reaches the top dead center, can the combustion kinetic energy and the engine rotational energy be effectively connected to achieve optimal kinetic energy conversion.

[0003] Traditional ignition systems lack real-time detection and adjustment mechanisms, and are unable to take into account comprehensive performance such as engine starting performance, power output, fuel consumption, and temperature control. For example, improper ignition angle at startup can lead to starting difficulties; ignition angle deviation during operation can lead to insufficient power, increased fuel consumption, or engine overheating.

[0004] The engine ignition angle control has problems such as inaccurate timing, inflexible adjustment, and difficulty in balancing performance. Therefore, we need to provide an online real-time detection ignition angle adjustment device and its use method. Summary of the Invention

[0005] The purpose of the present invention is to provide an online real-time detection ignition angle adjustment device and a method for use. By setting an adjustment mechanism, the high-voltage coil body on the metal shell surface can be driven to rotate, so that the tangential direction of the high-voltage coil and the flywheel magnetic flux lines form an angle deviation. After the high-voltage coil body rotates, the timing of the coil cutting the magnetic flux lines is advanced or delayed, thereby improving the starting performance of the engine and more effectively achieving the optimal starting state, so as to solve the problem raised in the above background technology that the traditional ignition system in the existing technology lacks a real-time detection and adjustment mechanism, and cannot take into account the comprehensive performance of the engine starting performance, power output, fuel consumption and temperature control. For example: improper ignition angle at startup will lead to starting difficulties; ignition angle deviation during operation will lead to insufficient power, increased fuel consumption or engine overheating.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: an online real-time detection ignition angle adjustment device, comprising:

[0007] The engine body, crankshaft, flywheel, adjustment mechanism and high-voltage package assembly, the crankshaft is rotatably installed in the engine body, the two flywheels are fixed on the crankshaft and rotate with it, the adjustment mechanism is installed between the two high-voltage package assemblies, one of the high-voltage package assemblies is installed on the outer shell on one side of the engine body, the two flywheels are fixed on the crankshaft, forming relative motion with the high-voltage package assembly, and the axis is fixed on the crankshaft surface. The adjustment mechanism is installed between the two high-voltage package assemblies to change the relative angle between the high-voltage package assembly and the flywheel, thereby adjusting the timing of the coil cutting the flywheel magnetic field to achieve precise control of the ignition advance angle.

[0008] Preferably, the adjustment mechanism includes a rectangular seat, an inner cavity, a disk body and an adjustment part. The disk body is rotatably mounted on one side of the rectangular seat. One side of the disk body is fixedly connected to the high-voltage package assembly close to the engine body, and the other high-voltage package assembly is fixedly connected to the rectangular seat. The adjustment part is installed in the inner cavity of the rectangular seat and is used to drive the rectangular seat and the high-voltage package assembly fitted with the rectangular seat to rotate synchronously.

[0009] Preferably, the adjusting part includes a worm and a worm wheel, the worm wheel is sleeved on the surface of the crankshaft and is located in the inner cavity, and a worm engaged with the worm wheel is rotatably installed in the rectangular seat to realize that the rotation of the worm drives the worm wheel, the rectangular seat and the high-voltage package assembly attached to the rectangular seat to rotate together.

[0010] Preferably, four indicator grooves are evenly distributed on the outer surface of the disc body, and an annular scale line matching the indicator grooves is provided on one side of the rectangular seat.

[0011] Preferably, the high-voltage package assembly includes a metal shell, a cavity and a high-voltage package body. The flywheel is located in the cavity inside the metal shell. The high-voltage package body is fixed to the surface of the metal shell and used in conjunction with the flywheel.

[0012] Preferably, a permanent magnet is installed on the surface of the flywheel. When the flywheel rotates, the magnetic field of the permanent magnet rotates with the flywheel, providing an alternating magnetic field for the coil in the high-voltage transformer body to cut the magnetic flux lines.

[0013] Preferably, the two high-voltage package bodies are connected to the spark plugs on the surface of the engine body through high-voltage wires.

[0014] Preferably, the minimum graduation value of the angle scale line is 1°, which is used to accurately display the relative rotation angle between the high-voltage coil assembly and the flywheel.

[0015] Preferably, the outer surface of the high-voltage package body is covered with a heat-insulating silica gel layer for isolating the high temperature generated when the engine is running and protecting the insulation of the coil inside the high-voltage package body.

[0017] The flywheels in the two metal shells are coaxially arranged at the same angle, and the two high-voltage coil bodies are initially arranged at the same angle. After the engine body is started, the crankshaft drives the two flywheels to rotate;

[0018] Use a hexagonal wrench to drive the worm to rotate, and the surface of the worm is engaged with the worm wheel, and the worm wheel is fixed in the rectangular seat. As the worm rotates, the rectangular seat is rotated, and at the same time, the metal shell fixed to one side of the rectangular seat rotates, driving the high-voltage package body on the surface of the metal shell to rotate;

[0019] When the high-voltage coil body rotates, an angle deviation occurs with the flywheel. Since the flywheel surface is provided with a permanent magnet, the tangent line inside the high-voltage coil body cuts the magnetic flux lines, which are transmitted to the spark plug through the high-voltage wire to adjust the ignition timing.

[0020] Since there are four indicator grooves evenly distributed on the outer surface of the disk body, and a ring scale line matching the indicator groove is provided on one side of the rectangular seat, the rotation of the rectangular seat drives the ring scale line to rotate, and the angle can be observed and adjusted through the indicator grooves on the surface of the disk body.

[0022] The present invention uses two flywheels in metal shells that are coaxially arranged at the same angle, and the two high-voltage coil bodies are initially arranged at the same angle. After the engine body is started, the crankshaft drives the two flywheels to rotate. By setting an adjustment mechanism, the high-voltage coil body on the surface of the metal shell can be driven to rotate, so that the tangential direction of the high-voltage coil and the flywheel magnetic flux lines form an angle deviation. After the high-voltage coil body rotates, the timing of the coil cutting the magnetic flux lines is advanced or delayed, thereby improving the starting performance of the engine and achieving the optimal starting state more effectively, so that the engine's comprehensive performance such as stronger power output, optimal temperature control, and lower fuel consumption can reach the best state.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] The present invention provides Figure 1-6 An online real-time detection ignition angle adjustment device is shown, comprising:

[0033] The engine body 1, crankshaft 2, flywheel 3, adjustment mechanism 4 and high-voltage package assembly 5, the crankshaft 2 is rotatably installed in the engine body 1, the two flywheels 3 are fixed on the crankshaft 2 and rotate with it, the adjustment mechanism 4 is installed between the two high-voltage package assemblies 5, one of the high-voltage package assemblies 5 is installed on the outer shell of one side of the engine body 1, the two flywheels 3 are fixed on the crankshaft 2, forming relative motion with the high-voltage package assembly 5, and the axis is fixed on the surface of the crankshaft 2. The adjustment mechanism 4 is installed between the two high-voltage package assemblies 5 and is used to change the relative angle between the high-voltage package assembly 5 and the flywheel 3, thereby adjusting the timing of the coil cutting the magnetic field of the flywheel 3 to achieve precise control of the ignition advance angle;

[0034] Specifically, the flywheels 3 in the two metal shells 51 are coaxially arranged at the same angle, and the two high-voltage coil bodies 53 are initially arranged at the same angle. After the engine body 1 is started, the crankshaft 2 drives the two flywheels 3 to rotate. By setting an adjustment mechanism 4, the high-voltage coil body 53 on the surface of the metal shell 51 can be driven to rotate, so that the tangential direction of the high-voltage coil and the magnetic flux lines of the flywheel 3 form an angle deviation. After the high-voltage coil body 53 rotates, the timing of the coil cutting the magnetic flux lines is advanced or delayed, thereby improving the starting performance of the engine and achieving the optimal starting state more effectively, so that the engine's comprehensive performance such as stronger power output, optimal temperature control, and lower fuel consumption can reach the best state.

[0035] The adjusting mechanism 4 includes a rectangular seat 41, an inner cavity 42, a disk 43 and an adjusting portion 44. The disk 43 is rotatably mounted on one side of the rectangular seat 41. One side of the disk 43 is fixedly connected to the high-voltage package assembly 5 close to the engine body 1. Another high-voltage package assembly 5 is fixedly connected to the rectangular seat 41. The adjusting portion 44 is installed in the inner cavity of the rectangular seat 41 and is used to drive the rectangular seat 41 and the high-voltage package assembly 5 fitted with the rectangular seat 41 to rotate synchronously.

[0036] The adjusting part 44 includes a worm 441 and a worm wheel 442. The worm wheel 442 is sleeved on the surface of the crankshaft 2 and is located in the inner cavity 42. The worm 441 engaged with the worm wheel 442 is rotatably installed in the rectangular seat 41 to realize that the rotation of the worm 441 drives the worm wheel 442, the rectangular seat 41 and the high-voltage package assembly 5 attached to the rectangular seat 41 to rotate together.

[0037] Four indicator grooves 6 are evenly distributed on the outer surface of the disc body 43 , and an annular scale line 7 that matches the indicator grooves 6 is provided on one side of the rectangular seat 41 .

[0038] The high-voltage package assembly 5 includes a metal shell 51 , a cavity 52 and a high-voltage package body 53 . The flywheel 3 is located in the cavity 52 inside the metal shell 51 . The high-voltage package body 53 is fixed to the surface of the metal shell 51 and is used in conjunction with the flywheel 3 .

[0039] A permanent magnet is installed on the surface of the flywheel 3. When the flywheel 3 rotates, the magnetic field of the permanent magnet rotates with the flywheel 3, providing an alternating magnetic field for the coil in the high-voltage transformer body 53 to cut the magnetic flux lines.

[0040] The two high-voltage transformer bodies 53 are both connected to the spark plugs on the surface of the engine body 1 through high-voltage wires.

[0041] The minimum division value of the angle scale line is 1°, which is used to accurately display the relative rotation angle between the high-voltage coil assembly 5 and the flywheel 3.

[0042] The outer surface of the high-voltage coil body 53 is covered with a heat-insulating silica gel layer, which is used to isolate the high temperature generated when the engine is running and protect the insulation of the coil inside the high-voltage coil body 53.

[0043] The relationship between the high-voltage coil rotation angle α and the ignition advance angle needs to be converted through the crankshaft 2 angle. For example, the radius R of the flywheel 3, the coil rotation α° corresponds to the crankshaft 2 angle β° = α° × (number of teeth on the flywheel 3 / number of teeth on the crankshaft 2)), to ensure that the adjustment amount is accurately matched with the engine ignition timing.

[0044] A method for using an online real-time detection ignition angle adjustment device comprises the following steps:

[0045] The flywheels 3 in the two metal shells 51 are coaxially arranged at the same angle, and the two high-voltage coil bodies 53 are initially arranged at the same angle. After the engine body 1 is started, the crankshaft 2 drives the two flywheels 3 to rotate;

[0046] A hexagonal wrench is used to rotate the worm 441, and the surface of the worm 441 engages with the worm wheel 442, which is fixed in the rectangular seat 41. As the worm 441 rotates, the rectangular seat 41 rotates. At the same time, the metal shell 51 fixed to one side of the rectangular seat 41 rotates, driving the high-voltage transformer body 53 on the surface of the metal shell 51 to rotate.

[0047] When the high-voltage coil body 53 rotates, an angle deviation is generated with the flywheel 3. Since the flywheel 3 is provided with a permanent magnet, the tangent line in the high-voltage coil body 53 cuts the magnetic flux line, which is transmitted to the spark plug through the high-voltage wire to adjust the ignition timing.

[0048] Since there are four indicator grooves 6 evenly distributed on the outer surface of the disk body 43, and an annular scale line 7 cooperating with the indicator groove 6 is provided on one side of the rectangular seat 41, the rotation of the rectangular seat 41 drives the annular scale line 7 to rotate, and the adjustment angle can be observed through the indicator grooves 6 on the surface of the disk body 43.

[0049] Working principle: two flywheels 3 are fixed on the crankshaft 2, the axis is coaxial with the crankshaft 2, and the permanent magnets are installed at the same angle; the two high-voltage coil bodies 53 are respectively fixed on the surface of the corresponding metal shell 51. Initially, the tangential direction of the high-voltage coil and the magnetic flux line direction of the permanent magnet of the flywheel 3 are at an angle of 0° (that is, the coil plane is perpendicular to the magnetic flux line), ensuring that the initial cutting position is synchronized, the worm 441 is engaged with the worm wheel 442, the rectangular seat 41 is sleeved on the crankshaft 2 through the inner cavity 42, and the disk body 43 is rotatably connected to the rectangular seat 41. At this time, the annular scale line 7 is aligned with the disk body 43 indicator groove 6, and the corresponding ignition advance angle is the reference value. The crankshaft 2 drives the two flywheels 3 to rotate synchronously, and the permanent magnets on the surface of the flywheel 3 form an annular alternating magnetic field. The magnetic flux lines radiate radially outward along the flywheel 3 and make a 360° circular motion as the flywheel 3 rotates. When not adjusted: the coil in the high-voltage coil body 53 maintains relative motion with the magnetic field of the flywheel 3, and the coil tangent cuts perpendicularly Cutting magnetic flux lines, according to Faraday's law of electromagnetic induction, the primary coil generates an alternating induced current, which is boosted by the secondary coil and transmitted to the spark plug through the high-voltage wire to achieve reference ignition. Use a hexagonal wrench to rotate the worm 441, and the worm 441 engages with the worm gear 442 fixed in the rectangular seat 41, driving the rectangular seat 41 to rotate around the axis of the crankshaft 2. When the rectangular seat 41 rotates, the metal shell 51 fixed to it rotates synchronously, driving the high-voltage coil body 53 on the surface of the metal shell 51 to rotate, so that the tangential direction of the high-voltage coil and the magnetic flux lines of the flywheel 3 form an angle deviation. After the high-voltage coil body 53 rotates, the timing of the coil cutting the magnetic flux lines is advanced or delayed. When the rectangular seat 41 rotates, the annular scale line 7 moves with the rectangular seat 41, and the relative position of the indicator groove 6 on the surface of the disk 43 and the scale line changes. The scale line value is observed through the indicator groove 6 to accurately read the relative rotation angle between the high-voltage coil and the flywheel 3, ensuring that the adjustment amount can be quantified;

[0050] After adjustment, the timing of the high-voltage coil cutting the magnetic field changes, and the matching relationship between the spark plug sparking moment and the piston position changes:

[0051] Early cutting: Ignition occurs before the piston reaches top dead center, and the combustion kinetic energy generates positive thrust in coordination with the direction of rotation of the crankshaft 2;

[0052] Delayed cutting: Ignition occurs after the piston passes top dead center, and the combustion kinetic energy pushes the piston downward, optimizing power output under high-speed conditions.

[0053] In addition, the present invention also provides a terminal device.
