ABSTRACT:
The invention provides a combustion chamber arrangement for an internal combustion engine which can attain stabilized firing performance and stabilized combustion performance during any load running of the engine. The combustion chamber arrangement includes a piston having a combustion chamber formed by recessing a top portion thereof along an axial direction, and a recessed portion formed by recessing a portion of a peripheral wall of the combustion chamber along the direction of the depth of the piston in a radially outward direction, whereby partially a rich mixture is produced within the recessed portion in order to improve the firing performance while mixture of a suitable concentration is dispersed and distributed within the combustion chamber so that the flame produced within the recessed portion may be propagated to the mixture within the combustion chamber.
