Stratified Charge Engines

  • J. H. Weaving

Abstract

The idea of the stratified charge engine (SCE) is old. Sir Harry Ricardo is credited with first demonstrating the pre-chamber type,1 and there is also an early GM patent dating back to 1922. The SCE is capable of bridging the gap between the diesel engine and the spark-ignition engine. The diesel has excellent fuel consumption and is almost the standard type of engine for commercial vehicles, while the spark-ignition (SI) engine with the lower compression ratio is smoother in running, quieter and free from objectionable odour. Because of its lower maximum cylinder pressures the SI engine is lighter and may be run at higher speeds, giving higher specific power.
