Many manufacturers considered stratified-charge technology, but only Honda successfully implemented it.
Roughly two decades before VTEC, low-emissions pioneer Honda began experimenting with valve manipulation for the sake of lower emissions. Relatively new to automotive manufacturing at that time, the Japanese carmaker rejected the idea of catalytic converters, and instead believed its stratified-charge CVCC (Compound Vortex Controlled Combustion) engine configuration was the answer to low emissions. Stratified-charge engines that inject fuel into the cylinders before ignition were nothing newthey dated back to the early 1900s. The design reduces combustion temperatures and detonation, improves cycle efficiency, reduces heat loss, and lowers pumping losses. It doesnâ
