Stratified charge engine

Diesel engine has little prospect of attaining an emission of NO below 1.0 g/mile. The inherently lean exhaust from Diesel makes an NO reduction catalyst useless, and would require an NO decomposition catalyst. The Wankel engine and the Honda stratified charge engine are also unable to reduce its NO emission below 1.0 g/mile.

The road test portion of the stratified-charge engine program was completed first. Blend concentrations ranging up to 40% methanol were evaluated in these tests to determine the possible operating limits of the blends in the GVGG vehicle. Leaded base fuels were used for these...
