COMBUSTION CHAMBER STRUCTURE FOR INTERNAL-COMBUSTION ENGINE

PURPOSE:To remove adhesion of fuel so as to improve combustion efficiency by forming a cavity located on the summit part of a piston in the vicinity of the center shaft of the piston so as to force the center of a entrance part provided in the cavity to be eccentric from the center of the piston.

Zusammenfassung:	PURPOSE:To remove adhesion of fuel so as to improve combustion efficiency by forming a cavity located on the summit part of a piston in the vicinity of the center shaft of the piston so as to force the center of a entrance part provided in the cavity to be eccentric from the center of the piston. CONSTITUTION:At the summit part of a piston 22, a roughly-spherical cavity 24 is formed. In the cavity 24, an entrance part being smaller in its diameter d than the maximum diameter D of the cavity is provided. The center of this entrance part is made eccentric by length A from a shaft center of the maximum diameter D in the direction of an injection nozzle 26. For this reason, a throttle B at this entrance side comes to be smaller than a throttle C at the entrance side on the opposite side. In this way, the adhesion of a fuel can be removed to improve combustion efficiency.
