Title: Internal combustion engine
Inventor: TAKAISHI TAKEO
IPC: F02B19/16
Filed: 1990-04-04
Abstract: PURPOSE:To reduce generation of NOx by installing plural precombustion chambers communicated through connecting holes with a main combustion chamber so that the main flow directions of combustion gases injected from the connecting holes of the precombustion chambers into the main combustion chamber become the same direction as that of intake air swirls formed in the cylinder. CONSTITUTION:More than one precombustion chambers 109a are provided relative to one cylinder, and fuel injection valves 104 for supplying fuels capable of self-compression ignition such as heavy oil, light oil, etc. or different types of fuels such as methanol, etc., are provided to each precombustion chamber 109a. When fuel is injected into each precombustion chamber 109a by each fuel injection valve 104, over-rich combustion takes place in each precombustion chamber 109a, and incomplete combustion takes place to decrease the combustion temperature to reduce the generation of NOx. After that, in the main combustion chamber unburnt gas from each precombustion chamber 109a is burnt along the direction of intake air swirls. The unburnt gases are thus completely burnt to restrict the generation of black smoke.
