Title: Piston of internal combustion engine
Inventor: AKAGI MITSUYASU
IPC: F02P13/00
Filed: 2001-01-15
Abstract: PROBLEM TO BE SOLVED: To provide an excellent combustion state by surely feeding fuel to near an ignition plug while stably holding a mixture in a piston cavity even in a high speed operation producing a strong gas flow in a direct injection spark ignition engine. SOLUTION: A return shape (10B) is provided on the inner peripheral wall surface of the piston cavity 10 in a part of the area excluding the area near the ignition plug 8. In a stratified charge combustion operation, the injected fuel enters into the cavity from a one end part and is mixed with air in a combustion chamber to form a rich mixture. Though the flow of the mixture collides initially with the side surface of the cavity, it reaches near the ignition plug at the other end of the cavity along the inner peripheral wall surface by a swirl S caused in a cylinder while the flow is held in the cavity without flowing to the outside by the bent shape of the inner peripheral wall surface.  Since the area of the peripheral wall surface in the cavity is not formed in the bent shape, the mixture is fed smoothly to an ignition plug portion, and an excellent igniting and combusting performances can be developed.
