dudleybenton 5 Posted December 5, 2020 Report Share Posted December 5, 2020 Sorry to have taken so long to respond… The main difference between spark-ignition (gasoline engine) and compression-ignition (diesel engine) operation is constant volume vs. constant pressure combustion. In a gasoline engine, combustion occurs so rapidly (the fuel and air are already in the combustion chamber with the plug fires) and near the top of the stroke so that the crank has little time to rotate and the piston moves only slightly with little change in volume. In a diesel engine, the fuel is sprayed into the cylinder as the piston is falling so that combustion occurs over a longer interval and corresponding change in volume.
