ABSTRACT:
Disclosed is an internal combustion engine comprising a main combustion chamber and an auxiliary combustion chamber. The auxiliary combustion chamber comprises a first and a second auxiliary chambers. The first auxiliary chamber has a spark plug therein and is connected to the main combustion chamber. The second auxiliary chamber has a fuel injection nozzle therein and is connected to the first auxiliary chamber and to the main combustion chamber. Air or a lean air-fuel mixture is introduced into the main combustion chamber via the intake valve. An extremely rich air-fuel mixture is formed into the second auxiliary chamber. The extremely rich air-fuel mixture is introduced into the first auxiliary chamber and a combustible mixture is formed in the first auxiliary chamber. The combustible mixture is ignited and a burning gas is injected into the main combustion chamber. A part of the burning gas is introduced into the second auxiliary chamber and, as a result, the extremely rich air-fuel mixture in the second auxiliary chamber is pushed out into the main combustion chamber. The entire extremely rich air-fuel mixture is burned in the main combustion chamber.
