Abstract

The invention discloses an in-line four-cylinder water-cooling diesel engine cylinder head cover which comprises a cover body, an oil-water separator, an oil filling opening cover installation hole and a wire harness clip installation hole, wherein at least four assembly holes are evenly formed in the cover body, oil leakage prevention assemblies are arranged in the assembly holes, the oil leakage prevention assemblies are used for installing oil seals and preventing engine oil from leaking from an oil injector and bolts, the oil-water separator is located at one end of the cover body and used for exhausting waste gas in a diesel engine body, the oil filling opening cover installation hole is located in one side of the cover body and used for installing an oil filling opening cover, and the wire harness clip installation hole is located along the side face of the cover body and used for fixing a wire harness of an engine. The in-line four-cylinder water-cooling diesel engine cylinder head cover has the advantages of being high in integrity, compact in structure and low in weight.

Description

technical field [0001] The invention belongs to the technical field of diesel engines, and in particular relates to a valve chamber cover of an inline four-cylinder water-cooled diesel engine. Background technique [0002] The function of the valve cover is to close the valve chamber, prevent the lubricating oil from leaking to the outside of the engine, and reduce the noise when the engine is running. The possible failures of the valve cover are deformation and oil leakage, so its performance has a great influence on the reliability and durability of the diesel engine. The rationality of the valve cover design affects the reliability and noise of the diesel engine. [0003] At present, the valve cover of many in-line four-cylinder diesel engines is not well integrated, which affects the compactness and noise of the diesel engine, increases the weight of the diesel engine, and increases the cost of the diesel engine, which is not economical.
