The invention discloses an integral intake valve, a cylinder cover and a gas engine. The integral intake valve is applied to the gas engine transformed on the basis of a diesel engine and comprises an integral intake valve retainer and at least two tappets connected to the integral intake valve retainer and perpendicular to the bottom end face of the integral intake valve retainer. The integral intake valve retainer is used for being matched with an integral intake valve seat ring at an integral intake throat opening formed in the cylinder cover so as to be opened and closed, so that opening and closing control of the integral intake valve is achieved; and the integral intake throat opening is matched with multiple exhaust throat openings corresponding to one same combustion chamber at the same time. According to the integral intake valve, the original two intake valves are designed in a combined mode to form a complete intake valve retainer part, interference generated during air intake of the two intake valves is completely eliminated, and the air inlet flow is effectively improved, so that the tumble flow effect in the combustion chamber of a developed gas engine is improved on the basis of the diesel engine.
Description
technical field [0001] The invention relates to the technical field of engine air 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, at present, more and more gas engines are transformed on the basis of diesel engines. For a diesel engine, the combustion mode is diffusion combustion, and a certain degree of swirl helps the oil jet to mix with the air, thereby improving the combustion process. Therefore, the intake port in the engine cylinder head is required to organize airflow during the intake process. sufficient swirl ratio. Among them, the vortex refers to the organized swirl movement of the gas around the axial direction of the cylinder. [0003] However, the combustion mode of the gas engine is premixed combustion, which does not require high eddy current strength, but requires small-scale turbulent motion to form a flame wrinkle surface, thereby acceleratin...
