A gas engine cylinder head

Abstract

The invention discloses a gas engine cylinder cover comprising a gas cylinder cover in which a gas inlet manifold and a gas mixing chamber are arranged; the gas cylinder cover is in an integrated structure with the gas inlet manifold and the gas mixing chamber; the gas inlet manifold is provided with a gas nozzle hole; an air inlet is corresponding to one end of the gas inlet manifold; the gas cylinder cover is integrated with the gas inlet manifold and the gas mixing chamber to form one part, so that the number of parts of an engine is reduced, installation processes are reduced, the whole quality is improved, and the structure is compact; the gas inlet manifold is integrated onto the gas cylinder cover, so that the strength of the gas inlet manifold is the same with that of the gas cylinder cover, the structural strength of the gas inlet manifold is extremely improved, the gas inlet manifold can bear the explosion mixture shock same to that on a combustor, and the reliability of the gas inlet manifold is enhanced.

Description

technical field [0001] The invention relates to the technical field of gas engines, in particular to a gas engine cylinder head. Background technique [0002] At present, commonly used gas engines all adopt single-point and multi-point gas injection technology, and the cylinder head, intake manifold, and independent design are then assembled. With such a design method, there will be many parts, cumbersome and complicated installation, the overall quality of the power system is heavy, not compact and beautiful, the structural strength is not good, the sealing is not good, and there are hidden dangers of air leakage; the air intake gasket needs to be replaced after long-term operation, and The versatility is not high, single-point or multi-point injection requires different cylinder heads and intake manifolds, and two types of cylinder heads need to be developed for the same model, resulting in high development costs. Contents of the invention [0003] Aiming at the deficie...
