Abstract:
1. An internal combustion engine comprising: a cavity in which a fuel can be combusted; a body moveable within said cavity, said cavity and moveable body together defining a first combustion chamber; a first fuel injector for injecting a first volume of fuel into said first combustion chamber; a housing defining an auxiliary combustion chamber; a passage extending from said auxiliary combustion chamber to said first combustion chamber; a valve moveable between a first position where said valve provides a high impedance to fluid flow between said auxiliary combustion chamber and said first combustion chamber, and a second position where said valve provides substantially unimpeded fluid flow between said auxiliary combustion chamber and said first combustion chamber; an auxiliary fuel and air injector for injecting a fuel/air mixture into said auxiliary combustion chamber, said fuel/air mixture comprising air sourced from outside of said first combustion chamber; ignition means for igniting said fuel/air mixture in said auxiliary combustion chamber to produce an ignited fuel/air mixture for igniting said first volume of fuel; and, wherein said first fuel injector and said housing are juxtaposed so that fuel injected by said first fuel injector and said ignited fuel/air mixture discharged through said passage are targeted at the same point in said first combustion chamber.
