Abstract
This paper describes a new stratified-charge combustion system called the Mitsubishi Combustion Process (MCP), accomplished by controlling the air swirl and improving the injection nozzle in regulating fuel injection, which reduces poisons from exhaust emissions of small engines. Experiments proved that the MCP engine reduces the emission level; for example, with gasoline the concentrations of HC, CO, and NO are 80 ppm, 0.20%, and 600 ppm, respectively, at the rated horsepower. The engine shows excellent performance in multifuel and starting characteristics.
The improvement of spray formation that has an important effect on exhaust emissions and other engine performance is also described.
