More Information
Summary:The utility model relates to a diesel piston with the pressure diffusion structure of two combustion chambers. A piston core is arranged in the W-shaped single-stage diffusion whirling chamber of a piston body, one end surface of the piston core is matched with the W-shaped chamber to form a convex surface, a slot which is arranged on the convex surface converges from the center to the periphery to form a slit, the other end surface of the piston core is provided with a circular ring groove with a curved surface, and the center of the piston core is provided with a circular through hole. The utility model can reduce heat loss and loss of momentum, and can increase the external power of the diesel.
