Abstract

The invention discloses a cylinder cover and a gas engine. The cylinder cover is applied to the gas engine transformed on the basis of a diesel engine; the cylinder cover comprises a first air inlet throat and a second air inlet throat which are formed in the cylinder cover, a first air inlet valve seat ring is arranged in the first air inlet throat, a second air inlet valve seat ring is arranged in the second air inlet throat, and the height H1 from the first air inlet valve seat ring to the bottom surface of the cylinder cover is greater than the height H2 from the second air inlet valve seat ring to the bottom surface of the cylinder cover. Compared with a traditional mode that two air inlet valve seat rings are symmetrically arranged, the cylinder cover has the advantages that airflow hedging interference in the direction of the center connecting line of the two air inlet valves can be effectively reduced, then the airflow kinetic energy loss is reduced, and the tumble effect in a combustion chamber can be better improved.

Description

Technical field [0001] Technical Field The present invention relates to an engine intake, particularly to a gas engine and a cylinder head. Background technique [0002] With the development of gas engine technology, there is currently, more and more gas engines are transformed on the basis of diesel engines. For diesel engines, its combustion mode is a diffusion combustion, a certain extent of eddy currents helps the oil bundle to improve the air, thereby improving the combustion process, and therefore, the intake air flow in the engine cylinder head is required to tissue airflow during intake. Sufficient eddy current ratio. Among them, the vortex refers to a swirling motion of the gas in the axial axial direction of the gas. [0003] However, the combustion mode of the gas engine is premixed, which is not high to the eddy current strength, and a small scale turbulent movement is required to form a flame pleated surface, thereby speeding the flame propagation speed, improving th...
