Hybrid Combustion Engine with Premixed Gasoline Homogeneous Charge and Ignition by Injected Diesel Fuel - Effects of Pre-Combustion Chamber Parameters -

A hybrid combustion engine in which a premixed gasoline homogeneous charge was ignited by a small amount of injected diesel fuel under a high compression ratio has been tested utilizing a modified 4-stroke cycle diesel engine with a pre-combustion chamber. This concept was effective not only in decreasing smoke density and fuel consumption but also in increasing engine output.
