Internal combustion engine for vehicle, has profile rings dividing combustion chamber into two or more chamber compartments during compression stroke, where chamber compartments in combustion chamber are merged during power stroke

摘要

The engine (1) has a combustion chamber including a cylinder (2) and a reciprocating piston (3), where the combustion chamber has a variable volume. Profile rings are mounted on a surface of the piston for dividing the combustion chamber into two or more chamber compartments during the compression stroke, where the chamber compartments in the combustion chamber are merged during the power stroke.
