ABSTRACT:
A combustion chamber structure for an internal combustion engine is configured with a combustion chamber surface that has a recess disposed around at least a pair of intake openings. The recess defines a pair of intake opening formation surfaces surrounding the intake opening with a pair of steps formed between the combustion chamber surface and the intake opening formation surfaces. A connecting surface interconnects the intake opening formation surfaces. The connecting surface is also recessed from the combustion chamber surface to form a step therebetween and a communication space being formed between the intake openings.
