The invention discloses a gas engine combustion system and a gas engine with the gas engine combustion system. The gas engine combustion system comprises a cylinder cover assembly, a cylinder body anda piston, wherein the cylinder cover assembly comprises a cylinder cover body, an intake mechanism and an exhaust mechanism which are respectively arranged on the cylinder cover body, an inner groove, a first air inlet, a second air inlet and a bulge structure are formed in a cylinder cover, the first air inlet and the second air inlet respectively communicate with the inner groove, the bulge structure is arranged on the inner wall surface of the inner groove and is located between the first air inlet and the second air inlet, a cylinder hole is formed in the cylinder body, the piston is movably arranged in the cylinder hole, the cylinder cover is matched with the cylinder body, and the inner groove corresponds to the cylinder hole. When air enters respectively through the first air inletand the second air inlet, two strands of airflow are prevented from interfering by the bulge structure, the flow speed and combustion speed of the air are guaranteed, and the problems of knock and high exhaust temperature of the gas engine are avoided.
Description
technical field [0001] The invention relates to the technical field of engines, in particular to a gas engine combustion system. The invention also relates to an engine. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] Since natural gas does not contain C-C chains in the combustion process, the soot emission generated during the combustion process is very low. At the same time, the carbon content in natural gas is low. When the same heat is released, the carbon emission is lower than that of diesel and gasoline fuel. Therefore, motor vehicles use Natural gas as fuel can effectively control emissions, which is of great significance to alleviate environmental pollution and reduce carbon emissions. [0004] However, the propagation speed of the laminar flame of natural gas is slow, which leads to the slow combustion speed of the gas engine, which is prone to the problem...
