Abstract
Disclosed is an internal combustion engine comprising a main chamber and an auxiliary chamber which are interconnected to each other via a connecting passage. The spark plug is located in the deep interior of the auxiliary chamber remote from the main chamber. The connecting passage comprises a first open end opening into the deep interior of the auxiliary chamber, and two second open ends opening into the main chamber. When the piston reaches the top dead center position, the main chamber defines therein two spaces having approximately equal volumes and including the corresponding second open ends. The second open ends are directed to the centers of the corresponding spaces.
