Combustion Technologies of High Compression Ratio Engine Using High Pressure Gasoline Injection (Fourth Report)

- Investigation of Fuel Consumption Performance at Partial Load Operation -

Abstract

Further improvement of thermal efficiency in gasoline engine is necessary by raising the compression ratio and specific heat ratio. In our previous papers, a new combustion technology to avoid irregular combustion in maximum load condition under ultra-high compression ratio was suggested and validated. This paper investigates fuel consumption performance at partial load by combining lean combustion strategies.
