Abstract

The invention discloses an open cylinder head cleaning system. The idea of ​​the invention is to solve the water accumulation and dust accumulation in the groove cavity of the open cylinder head independently and online only through the components of the engine itself and the ECU control program without relying on external equipment. question. Specifically, based on the existing structural characteristics of the engine cylinder head, a simple and practical air blowing and water drain channel is provided, and the air blowing air source does not need to rely on external equipment, and directly draws the air after the supercharger of the engine itself, and Using the air control valve and engine ECU, active cleaning, purging and drainage control functions are realized based on the driver's request or vehicle mileage. The invention effectively solves the problem of water accumulation and dust accumulation in the groove cavity of the open cylinder head, and avoids corrosion and damage of components such as the main body of the fuel injector nozzle and the threaded section of the pressure block bolt. Therefore, the invention can significantly improve the engine zero Stability and reliability of components.

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. The closed cylinder head, which is integrally formed with the shroud, completely seals the top surface of the cylinder head, leaving only the injector mounting holes, pressure block bolt holes, etc. These mounting holes will form an axial seal with these components through the sealing ring . The disadvantage of this closed cylinder head guard is that the axial sealing of the injector and other components and the cylinder head needs to be ensured, otherwise the oil in the cylinder head will leak. The design of the contact surface, the tolerance control and the material of the sealing ring have high requirements, and the sealing performance is extremely difficult to control. [0003] Another type of cylinder head is the open type. The open cylinder head on...
