The invention discloses a diesel combustion chamber which is offset with the center of a piston body. The combustion chamber is located in the lower part of the piston body, but the center of the combustion chamber has a certain deviation from the center of the piston. The purpose of this design is to fit the structure of the original two valve diesel engine and the new matching injector. The upper half of the combustion chamber shape round pool; the lower part is concave shaped combustion chamber; combustion chamber surrounded by a ring of necking necking, annular combustion chamber will be divided into peripheral and concave slope, the center of the combustion chamber is a convex core large angle. The lower part of the round pool at the upper half of the combustion chamber is a shallower slope at the inner edge, and then the concave of the transition arc with a deep radius. The inclined plane and the concave face are connected by the arc of the beta angle and the arc of the R1. The invention can reasonably control the vortex intensity and the shape, the fuel and air mix combustion, and fuel not adhered to the wall surface of the combustion chamber, the convex core of large angle can eliminate dead volume to burn fully, improve engine power and reduce emissions.
