Engine ignition chamber system with elliptical conical passage

The invention discloses an engine ignition chamber system with an elliptical conical passage. The engine ignition chamber system comprises a housing and a housing cover, wherein a cavity in the housing and the housing cover forms an ignition chamber, the housing cover is located at the top end of the ignition chamber, a fuel supply device and an ignition device are arranged on the housing cover, the housing is installed on a cylinder cover of an engine, and a space defined by an air cylinder, a piston and the cylinder cover of the engine forms a main combustion chamber, the bottom end of the housing extends into the main combustion chamber, a plurality of channels are formed near the bottom end of the housing, and the channels communicate with the ignition chamber and the main combustion chamber; and at least one of the plurality of channels mentioned above adopts an elliptic conical structure, namely a cross section of the channel is oval, and the longitudinal section of the channel is conical. According to the engine ignition chamber system, the turbulence intensity of turbulent flame jet flow in the working process of the ignition chamber type engine is further improved, flame propagation is accelerated, the combustion is more sufficient, and the performance of the engine is improved.
