stratified charge engine

stratified charge engine
An internal combustion engine in which a small portion of extremely rich fuel and air is ignited and in turn ignites a much leaner fuel-air mixture. The lean mixture might not fire by itself unless it is ignited by the flame of the burning rich mixture. Its advantage is lower peak c'bustion temperatures, greater fuel economy, and a decrease in pollutant emissions. The Honda CVCC engine which initiates combustion in a small auxiliary prechamber is one type of stratified charge engine (to be precise, the CVCC should actually be called a dual-combustion engine). Another type is Texaco's which uses turbulence in the incoming mixture to induce stratification.
