Problems solved by technology

When there is a lot of emulsified engine oil, it is easy to block the crankcase ventilation system, resulting in high pressure in the engine crankcase and oil leakage. At the same time, the oil emulsion will pollute the supercharger, intercooler, etc., affecting the normal operation of the engine.

Abstract

The invention discloses an engine cylinder head cover. The engine cylinder head cover comprises a cylinder head cover body, electric heating mechanisms and a plug connector. The electric heating mechanisms are uniformly arranged in the peripheral wall surfaces of the cylinder head cover body. And the plug connector is arranged at one end of the cylinder head cover body, one end of the plug connector is electrically connected with the electric heating mechanisms, and the other end of the plug connector is electrically connected with an ECU, wherein the ECU can control the heating mechanisms tobe started and stopped. Therefore, the engine cylinder head cover has the advantages that the structure is simple and reasonable, and water vapor in an engine is prevented from generating condensate water and engine oil emulsion on the inner wall of the cylinder head cover, so that normal operation of an engine is guaranteed.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine cylinder head cover. Background technique [0002] The cylinder head cover of the engine is located on the top of the engine, and its main function is to prevent external impurities from entering the engine and play a role of sealing. Inside the cylinder head cover, engine rocker arms, valves, camshafts and other parts are running at high speed, during which a lot of oil particles and oil mist will be splashed on the cylinder head cover. [0003] When the engine is burning, some gas will leak out of the combustion chamber, and finally be discharged out of the engine through the oil pan, cylinder head cover, and breather. The current new emission regulations require that the crankcase ventilation be connected to the engine intake to avoid the emission of pollutants. The exhaust gas produced by engine combustion contains a small amount of water vapor, and if the fuel is ...
