Engine (110) has a plurality of combustion chambers, each of which is divided into an ignition chamber (114) and a fist combustion chamber (130). The chambers (114 and 130) awe linked by a transfer tube (150) defining a passageway (152) facilitating communication between the ignition chamber (140) and the first chamber (130). A valve (154) is prod for selectively opening and closing the passage (152). Tube (150) is provided with an opening (164) intermediate of its length allowing fuel to be injected via a fuel injector (138) into the passage (150). In a first stage of a compression stroke of a piston of the engine (110), a first volume of fuel is injected via injector (138) through opening (164) Into the passage (150). At this time, the valve (154) is in the open position so that the fuel together with air is swept into the chamber (144). In a second phase of the compression stroke the valve (154) is closed isolating the chamber (144) from the chamber (130). A second volume of fuel is also injected by the injector (138) into the passage (152). During a third phase of the compression stroke a spark plug (148) is operated to produce a spark to commence combustion of the fuel and air within the chamber (144). During a fourth phase of the compression stroke, valve (154) is rapidly opened allowing burning fuel and air to pass from chamber (144) into the passage (152) where it mixes with and causes limited combustion of the fuel within the passage (152). The products therefrom are then ejected at sonic speed through opening (162) of the tube (150) into the first combustion chamber (130) where it mixes with the air to complete combustion.
