ABSTRACT:
Disclosed is an internal combustion engine comprising a main combustion chamber and an auxiliary combustion chamber which are interconnected to each other via a connecting passage. The opening of the connecting passage is arranged to be directed to the central portion of the piston when the piston reaches the top dead center. The combustible mixture in the auxiliary combustion chamber is ignited. As a result, a burning jet is injected into the main combustion chamber. An additional auxiliary combustion chamber having no spark plug therein is formed in the piston. The additional auxiliary combustion chamber opens onto the central portion of the top face of the piston. The combustible mixture in the additional auxiliary combustion chamber is ignited into an explosion by the burning jet injected from the connecting passage.
