Honda's CVCC engine, released in the early 1970s models of Civic, then Accord and City later in the decade, is a form of stratified charge engine that had wide market acceptance for considerable time. The CVCC system had conventional inlet and exhaust valves and a third, supplementary, inlet valve that charged an area around the spark plug.
A type of stratified charge technology, it was publicized on October 11, 1972 and licensed to Toyota (as TTC-V), Ford, Chrysler, and Isuzu before making its production debut in the 1975 ED1 engine. As emission laws advanced and required more stringent admissible levels, CVCC was abandoned in favour of PGM-FI (Programmed Fuel Injection) on all ...
After 14 years of research and development Otto succeeded in creating the compressed charge internal combustion engine May 9, 1876. Otto found a way to layer the fuel mixture into the cylinder to cause the fuel to burn in a progressive, as opposed to explosive fashion. He referred to this as being a layered or stratified charge.
Since mixtures too lean cannot be ignited with a spark-plug (due to a lack of fuel), the charge needs to be stratified (e. g. a small zone of fuel/air mixture around the spark plug needs to be created). [13] To achieve such a charge, a stratified charge engine injects the fuel during the latter stages of the compression stroke.
The WST engine has a common-rail direct injection system operating on a stratified charge principle. Similar to a Diesel engine and unlike a conventional Wankel engine, the WST engine compresses air rather than an air–fuel mixture as in the four-cycle engine compression phase. Fuel is only injected into the compressed air shortly before top ...

Stratified charge compression ignition also relies on temperature and density increase resulting from compression. However, it injects fuel later, during the compression stroke. Combustion occurs at the boundary of the fuel and air, producing higher emissions, but allowing a leaner and higher compression burn, producing greater efficiency.
