Description

technical field [0001] The invention relates to the related field of an internal combustion engine fuel injection system, in particular to an atomizing type internal combustion engine fuel injection solenoid valve. Background technique [0002] Internal combustion engines are widely used in the existing technology, such as transportation, large-scale equipment operation and other fields are widely used, which will be applied to the fuel injection system, the fuel injection system sends oil to the into the combustion chamber for combustion. [0003] In actual use, the existing fuel injection system has the following problems: [0004] 1. During the injection process, it is inevitable that uneven injection will lead to insufficient combustion. In this regard, some existing technologies adopt the atomization method. However, the atomization structure in the prior art is often complicated and the cost is high. , such as using parts such as heat exchangers for atomization, the ...

AI Technical Summary

Problems solved by technology

[0004] 1. During the injection process, it is inevitable that uneven injection will lead to insufficient combustion. In this regard, some existing technologies adopt the atomization method. However, the atomization structure in the prior art is often complicated and the cost is high. , such as using parts such as heat exchangers for atomization, the installation structure of the heat exchanger is relatively complicated, and there are many restrictions on the use

[0005] 2. In the prior art solenoid valve, due to blockage or pressure fluctuation, the oil chamber is over-pressurized, and sometimes the pressure cannot be released in time

[0006] 3. There is a need to clean the oil cavity in the prior art, but it is difficult to clean it during operation and maintenance

[0007] 4. In the prior art solenoid valve, when the oil supply pressure is large due to the oil supply deviation, water hammer is prone to occur

[0008] 5. The electromagnetic coil structure in the prior art is difficult to take into account the problems of firmness, large magnetic flux and material saving at the same time
