Novel gas engine piston

Abstract

The invention discloses a novel gas engine piston, and belongs to the field of engine pistons. The problems that a combustion chamber of a traditional engine piston is low in gas mixing and combustion efficiency are solved. An engine comprises a piston body, the combustion chamber is formed in the top of the piston body and comprises a combustion chamber bottom face and a combustion chamber wall face, the bottom end of the combustion chamber wall face is connected to the combustion chamber bottom face, the top end of the combustion chamber wall face obliquely extends towards one side of the axis of the piston, and a transition circular arc is arranged between the combustion chamber wall surface and the combustion chamber bottom surface. According to the novel gas engine piston, the combustion speed in a cylinder can be increased, the economical efficiency and emission performance of the gas engine are improved, and ventilation and combustion in the combustion chamber are promoted.

Description

technical field [0001] This invention relates to engine pistons, and more particularly, it relates to a novel gas engine piston. Background technique [0002] The in-cylinder turbulence intensity has an important influence on the rapid combustion in the gas engine cylinder. It is of great significance to improve the in-cylinder turbulence intensity by optimizing the shape of the combustion chamber, thereby improving the rapid propagation of the flame in the cylinder, and improving the power and economy of the gas engine. [0003] At present, most gas engines are improved on the basis of diesel engines. The air passages of diesel engines are mainly volute air passages, and the performance of the air passages is dominated by vortex and supplemented by tumble flow. Current engine pistons have a variety of combustion chamber structures, including deep groove structures and W-shaped structures, but the combustion chambers of existing engine pistons still need to be improved in te...
