Abstract
An internal combustion engine, including a main combustion chamber serving as a main combustion chamber, an auxiliary combustion chamber adjacent to the main combustion chamber and smaller in capacity than the main combustion chamber, and a partition wall between the main combustion chamber and the auxiliary combustion chamber, the partition wall including an injection hole by which the main combustion chamber and the auxiliary combustion chamber communicate. A fuel supply device supplies fuel to the main combustion chamber and the auxiliary combustion chamber. A mixture forming device forms a mixture of air and the supplied fuel in the main combustion chamber, away from the partition wall before ignition. An ignition device ignites the fuel in the auxiliary combustion chamber, propelling an ejecting torch flame into the mixture of air and fuel in the main combustion chamber through the injection hole, thereby burning the mixture of air and fuel in the main combustion chamber.
