摘要

An internal combustion engine with combustion chambers which create a squish and swirl of an air-fuel mixture is disclosed. In the disclosed engine an inner wall of a cylinder head and a top end of a piston are provided with at least two projected regions defining gaps for creating the squish and swirl of the air-fuel mixture toward the end of the compression stroke of the piston.
