[0035] 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 described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figure 1 As shown, an embodiment of the present invention discloses a method for adjusting the combustion state of an engine, wherein the engine comprises a body, an electromagnet arranged outside a fuel nozzle, and a first discharge port arranged outside a combustion chamber, and the adjustment method comprises:

[0037] Step S11, obtaining the current temperature of the engine and the current exhaust gas concentration at the tail exhaust port.

[0038] In the present application, an electromagnet is arranged outside the fuel nozzle of the engine, and a discharge port is arranged outside the combustion chamber, where the electromagnet and the discharge port can generate a magnetic field or an electric field, the magnetic field generated by the electromagnet can affect the fuel atomization effect, and the electric field generated by the discharge port can promote ion movement, increase the flame propagation speed, change the center of gravity of the flame, make the combustion more complete, and improve thermal efficiency; further, in order to adjust the combustion state of the engine through the magnetic field or the electric field, it is necessary to first collect the operating parameters of the engine, which may specifically include the current temperature of the engine when it is working and the current exhaust gas concentration of the tail exhaust port; it can be understood that the exhaust gas concentration characterizes the degree of completeness of the engine fuel combustion, and of course the combustion state of the engine can also be analyzed through the exhaust gas concentration.

[0039] In a specific embodiment, the acquisition of the current temperature of the engine and the current exhaust gas concentration at the tail exhaust port may include: acquiring the current temperature of the combustion chamber of the engine through a pre-set temperature sensor, and obtaining the current exhaust gas concentration by detecting the concentration values ​​of carbon monoxide and nitrides in the pollutants discharged from the tail exhaust port of the engine at the current moment. Specifically, the current temperature of the combustion chamber of the engine can be acquired through a temperature sensor or other device, and the current exhaust gas concentration discharged from the tail exhaust port of the engine at the current moment can be determined through a pollutant concentration monitoring device, etc. The exhaust gas concentration is mainly the concentration value of pollutants such as carbon monoxide and nitrides; the fuel combustion state of the engine can be roughly determined based on the current temperature of the combustion chamber and the current exhaust gas concentration at the tail, and the temperature and exhaust gas concentration corresponding to different degrees of fuel combustion are different.

[0040] Step S12: determining an adjustment strategy corresponding to the current combustion state of the engine according to the current temperature and the current exhaust gas concentration.

[0041] Furthermore, the current temperature of the engine's combustion chamber and the current exhaust gas concentration at the tail obtained according to the above steps can determine the fuel combustion state of the engine, and the adjustment strategy for the current combustion state can be determined according to the difference between the current combustion state and the preset ideal combustion state, such as the need to promote fuel atomization or combustion degree, etc.

[0042] In a specific embodiment, the adjustment strategy corresponding to the current combustion state of the engine determined according to the current temperature and the current exhaust gas concentration may include: determining the current combustion state of the engine according to the current temperature and the current exhaust gas concentration; determining the adjustment strategy for adjusting the current combustion state based on the current combustion state and the working state of the electromagnet and the working state of the first discharge port at the current moment. Specifically, the current combustion state of the engine can be determined according to the current temperature and the current exhaust gas concentration, and in the process of determining the adjustment strategy for the current combustion state, the working state of the electromagnet and the working state of the first discharge port set on the engine at the current moment can be considered, so that the adjustment operation for the electromagnet and the first discharge port can be set according to the adjustment expectation of the current combustion state, that is, the adjustment strategy for adjusting the current combustion state is determined, and the strategy may specifically include the adjustment operation of the working state of the electromagnet and the first discharge port.

[0043] Step S13: Based on the adjustment strategy, the currents of the electromagnet and the first discharge port are controlled respectively, so as to adjust the combustion state of the engine through the magnetic field and / or electric field generated by the electromagnet and the first discharge port.

[0044] In the present application, the above steps can be used to obtain an adjustment strategy for the current combustion state of the engine; further, based on the adjustment strategy, the working state of the electromagnet and the first discharge port set on the engine can be adjusted, and the current of the electromagnet and the first discharge port can be adjusted so as to control the intensity of the magnetic field and / or electric field generated by the electromagnet and / or the first discharge port through the current, and the intensity of the magnetic field and / or electric field can be adjusted to affect the fuel atomization process of the fuel nozzle in the engine and the fuel combustion process in the combustion chamber in the engine. It can be understood that the magnetic field can make the fuel atomization receive the effect of the additional magnetic moment, so that the cohesive force between molecules is weakened and relaxed, thereby making the average diameter of the ejected oil droplets thinner, and improving the evaporation and mixing between the oil droplets and the air. Therefore, when the fuel enters the combustion chamber for combustion after being acted upon by the electromagnetic field, the combustion intensity increases, the efficiency is improved, the fuel consumption rate is reduced, and the smoke is reduced. Moreover, electric and magnetic fields can provide the fuel with the energy needed for activation, causing resonance and energy transition in the fuel atomic layer, breaking the fuel saturated molecular chain, breaking the large molecular clusters into small molecules, thereby greatly enhancing the activity of the molecules and promoting more complete combustion of the fuel; when hydrocarbon fuels burn, a large number of positive and negative ions are generated in the flame, so if the flame is placed in an external electric and magnetic field, the movement trajectory of the ions will inevitably change. Electric and magnetic fields can cause the ions or ion clusters generated by combustion to collide with oxygen atoms, which is conducive to promoting the formation of mixed gas, increasing the flame propagation speed, changing the center of gravity of the flame, making the combustion more complete, and improving thermal efficiency.

[0045] It should be pointed out that the AC electric field has a better effect on promoting flames than the DC electric field. Therefore, in a specific embodiment, the electromagnet is installed outside each fuel nozzle and connected to an AC power supply to generate a magnetic field to affect the fuel atomization process of the engine. In addition, the first discharge port is installed on both sides of the combustion chamber outside the engine and connected to an AC power supply to generate an alternating electric field to affect the fuel combustion process. The fuel combustion state can be adjusted by adjusting the electric field strength and magnetic field strength inside the engine.

[0046] In a specific embodiment, the current of the electromagnet and the first discharge port is controlled respectively based on the adjustment strategy so as to adjust the combustion state of the engine through the magnetic field and / or electric field generated by the electromagnet and the first discharge port, which may include: if the adjustment strategy indicates that the temperature of the combustion chamber needs to be increased, the current of the electromagnet and / or the first discharge port is increased to adjust the combustion state of the engine through the magnetic field and / or electric field generated by the electromagnet and the first discharge port. Specifically, if the temperature of the combustion chamber is less than the preset temperature threshold, the adjustment strategy may be to increase the current of the electromagnet and the first discharge port, and affect the fuel combustion process by increasing the intensity of the magnetic field and / or electric field, and increase the temperature of the combustion chamber to adjust the combustion state of the engine. In a specific embodiment, when the temperature in the combustion chamber is less than the first preset temperature threshold, the current control switch of the fuel nozzle electromagnet can be selected to open or the power-on current can be increased; further, when the temperature in the combustion chamber is less than the second preset temperature threshold, the current control switch of the first discharge port corresponding to the engine premixed combustion can be selected to open or the power-on current can be increased.

[0047] In another specific embodiment, the engine further includes a second discharge port disposed on both sides of the outside of the tail exhaust port, and connected to an AC power source, for generating an alternating electric field to affect the exhaust emission process; accordingly, after the current of the electromagnet and the first discharge port are respectively controlled based on the adjustment strategy, it can also include: obtaining the actual exhaust concentration of the tail exhaust port of the engine at present, and adjusting the alternating electric field generated by the current of the second discharge port to affect the number of positive ions and ion groups in the pollutants discharged by the engine combined with oxygen anions. Specifically, the second discharge port disposed at the tail of the engine can promote the number of positive ions and ion groups such as C and NO combined with oxygen anions through the generated alternating electric field, thereby reducing carbon smoke and NOx emissions; the current of the second discharge port is also adjusted according to the actual exhaust concentration of the tail exhaust port of the engine at present, so as to affect the number of positive ions and ion groups in the pollutants combined with oxygen anions through the electric field generated by the current.

[0048] In a specific embodiment, Figure 2 The figure shows the position of the engine and the electromagnet, where 1 is the outer wall of the engine cylinder liner; 2 is the compressed gas inlet; 3 is the igniter; 4 is the fuel delivery and fuel distribution; 5 is the fuel nozzle; 6 is the combustion area; 5-A is the fuel nozzle electromagnet; 1-B is the front premixed combustion (first) discharge port; 1-C is the rear exhaust outlet (second) discharge port. The voltage of the AC power supply of the first discharge port and the second discharge port is , is the angular frequency, , is the frequency. The induced electromotive force generated is ,in ; By placing the flame in an external electric field, the movement trajectories of the positive and negative particles in the flame can be changed, thereby enhancing the combustion process and the stability of the flame as well as the generation and emission of pollutants at the tail. Figure 3 The diagram shows the position of the fuel injection solenoid (5-A). The voltage of the AC power supply can be , is the angular frequency, , is the frequency; for the electromagnet of the fuel nozzle, the magnetic flux generated is ,in is the working magnetic flux, , is the maximum value of the magnetic induction intensity in the electromagnet, and S is the core area; the electromagnet includes an iron core and a coil, the coil is wound on the iron core, the coil is made of high-temperature resistant copper coil, and the material of the iron core is nickel, which can ensure high temperature resistance and generate a better magnetic field; and, in order to prevent the electromagnet from magnetizing the combustion chamber through the outer shell, an insulating and high-temperature resistant ceramic material can be used to seal it.

[0049] In another specific embodiment, the electromagnet corresponding to the fuel nozzle of the engine, the first discharge port corresponding to the combustion chamber and the second discharge port corresponding to the tail exhaust port can be connected to the control unit respectively, and the three parts can be controlled and adjusted separately to provide more precise magnetic and electric field adjustment and improve the precise adjustment of fuel combustion.

[0050] It can be seen that the present application can adjust the magnetic field strength and electric field strength in the fuel atomization stage and the premixed combustion stage through the electromagnet arranged in the fuel nozzle of the engine and the first discharge port arranged in the combustion chamber of the engine, so as to affect the fuel atomization and combustion process of the engine, affect the thermal efficiency of the engine, and realize the controllable adjustment of the combustion state of the engine. In addition, in combination with the second discharge port arranged at the tail exhaust port of the engine, the number of positive ions and ion groups combined with oxygen negative ions in the exhaust gas can be affected by the alternating electric field of the second discharge port, which can reduce pollutant emissions. In this way, the present application can controllably adjust the thermal efficiency of the engine by adjusting the magnetic field and / or electric field strength in which the engine is located, and can adjust pollutant emissions.

[0055] It can be seen that the present application can specifically adjust the magnetic field strength and electric field strength in the fuel atomization stage and the premixed combustion stage through electromagnets and discharge ports, which can affect the thermal efficiency of the engine and achieve controllable adjustment of the engine combustion state.
