Stratified charge engine meaning

Stratified charge engine definition

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 combustion 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.
