This patent describes a stratified charge rotary combustion engine having a housing having a running surface surrounding a working chamber, the running surface having a two-lobed profile, the lobes forming a junction in a top-dead-center region of the housing, a rotor mounted for rotation in the working chamber, a fuel injection and ignition system placed in the top-dead center region. It includes a pilot fuel injector fuel into the working chamber; a first spark plug located upstream of the pilot fuel injector for igniting fuel injected by the pilot fuel injector, the pilot fuel injector and the first spark plug being located on a downstream side of the junction; a main fuel injector for injecting fuel into the working chamber, the ignited pilot fuel acting to ignite fuel injected by the main injector; and a second spark plug located upstream of the main fuel injector and located upstream of the junction for igniting fuel/air mixture in the working chamber.
