stratifiedcharge
Stratified charge is a combustion strategy used in internal combustion engines to improve fuel efficiency and reduce emissions. The core principle involves creating a fuel-air mixture within the combustion chamber that is not uniform, or stratified. Typically, this means creating a richer fuel-air mixture near the spark plug for easier ignition and a leaner mixture in the rest of the combustion chamber. This leaner mixture burns more slowly and at a lower temperature, which can reduce the formation of nitrogen oxides (NOx).
Various designs have been employed to achieve stratification. Some systems use a pre-chamber or a divided combustion
The goal of stratified charge is to combine the benefits of igniting a readily combustible mixture with
