Abstract

The invention discloses an integral intake valve, a cylinder head and a gas engine, which are applied to a gas engine transformed on the basis of a diesel engine. There are at least two tappets on the bottom end face of the integral intake valve disc. The seat ring cooperates with the opening and closing to realize the switch control of the integral intake valve, and the integral intake throat matches with multiple exhaust throats corresponding to the same combustion chamber at the same time. The integral intake valve is equivalent to the joint design of the original two intake valves to form a complete intake valve disc, which completely eliminates the interference caused by the intake of the two intake valves and effectively improves the intake air intake. flow, thus more helpful to enhance the tumble flow effect in the combustion chamber of the gas engine developed on the basis of improving the diesel engine.

Description

technical field [0001] The invention relates to the technical field of engine intake, in particular to an integral intake valve, a cylinder head and a gas engine. Background technique [0002] With the development of gas engine technology, more and more gas engines are modified on the basis of diesel engines. For a diesel engine, its combustion mode is diffusion combustion, and a certain degree of vortex helps the oil jet to mix with air, thereby improving the combustion process. Therefore, it is necessary for the intake port in the engine cylinder head to organize the airflow during the intake process. Sufficient swirl ratio. Among them, the vortex refers to the organized swirling movement of the gas around the cylinder axis. [0003] However, the combustion mode of a gas engine is premixed combustion, which does not require high vortex strength, but requires small-scale turbulent motion to form flame folds, thereby speeding up flame propagation and improving thermal effi...
