ABSTRACT:
A combustion chamber of an internal combustion engine is disclosed. The combustion chamber comprises an approximately triangular upper wall in at least one vertical section passing through the center of the combustion chamber, a squish area formed by a peripheral portion of upper wall of piston and the upper wall of the combustion chamber, and a step which is formed on at least one of the peripheral portions of the piston and the upper wall of the combustion chamber. The radial and outward flows impinge on the step inside of the squish area. A height of the step in at least the vicinity of the vertical section is approximately equal to the smallest clearance of the squish area.
