The invention discloses an open type cylinder cover cleaning system which has the conception that the problems of water storage and dust accumulation in a groove cavity of an open type cylinder cover are autonomously and online solved only through parts of an engine and an ECU (Electronic Control Unit) control program without depending on external equipment. Specifically, based on the existing structural characteristics of an engine cylinder cover, a practical blowing and water draining channel with a simple structure is arranged, a blowing air source does not need to depend on external equipment, compressed air of a supercharger of an engine is directly led, and an air control valve and an engine ECU (Electronic Control Unit) are utilized, and active cleaning and purging drainage control functions are realized based on two dimensions of driver request or vehicle mileage. The problem that water and dust are accumulated in the groove cavity of the open type cylinder cover is effectively solved, a fuel injector nozzle body, the threaded section of a pressing block bolt and other parts are prevented from being rusted and damaged, and therefore the stability and reliability of engine parts can be remarkably improved.
Description
technical field [0001] The invention relates to the field of engines, in particular to an open cylinder head cleaning system. Background technique [0002] Engine cylinder heads are generally divided into open and closed. Closed cylinder head, which is integrally formed with the guard cover, completely seals the top surface of the cylinder head, leaving only the injector installation holes, pressure block bolt holes, etc., and these installation holes will form axial seals with these parts through the sealing ring . The disadvantage of this closed cylinder head guard is that it is necessary to ensure the axial sealing of the fuel injector and other parts and the cylinder head, otherwise the oil in the cylinder head will leak, and the general engineering experience shows that the axial sealing of the cylinder is of great importance The design of the contact surface, the tolerance control and the material of the sealing ring have high requirements, and the sealing performanc...
