ABSTRACT:
An improved method of operating a two cycle direct injected internal combustion engine so as to provide good ignition and combustion even when operating in a stratified condition. This is achieved either by extending the duration of firing of the spark plug either by extending a single firing or providing multiple firings per cycle or by changing the energy level across the gap of the spark plug during its firing.
