Abstract
A squish surface having the shape of a plane surface orthogonal to the axis of a piston is formed on the intake side of the piston top surface. A squish area is formed between the squish surface and a plane surface-shaped squish surface on the cylinder head side, and at the same time, a squish guide surface is formed in the piston top surface so as to be continuously ridged from the squish surface toward the vicinity of a spark plug.
