A split phase fuel conditioner ( 10 ) includes a main body 20 defining an ignition chamber ( 22 ). A transfer passage ( 24 ) is in fluid communication between the ignition chamber ( 22 ) and main combustion chamber ( 14 ) of an engine ( 12 ) to which the conditioner is coupled. A first valve ( 28 ) selectively opens and closes a throat ( 26 ) of the transfer passage ( 24 ) to control fluid communication between the ignition chamber ( 22 ) and main combustion chamber ( 14 ). A first injector ( 30 ) is coupled to the main body ( 20 ) for injecting the first fuel volume into ignition chamber ( 22 ). A second fuel injector ( 32 ) which is carried by, but operated independently of, the first valve ( 28 ), injects a second volume of fuel directly into the transfer passage ( 24 ). Initially, the injector ( 30 ) injects the first fuel volume into the ignition chamber ( 22 ) where it is ignited to form an ignition plasma. Prior to opening valve ( 28 ), the second fuel injector ( 32 ) injects a second fuel volume into the transfer passage ( 24 ). The valve ( 28 ) is then opened allowing the ignition plasma to condition the second fuel volume by raising its temperature above its self-ignition temperature vaporising the second fuel volume. The ignition plasma then sweeps the conditioned second fuel volume into the combustion chamber ( 14 ) where it seeks out further oxygen within the combustion chamber ( 14 ) and combusts in a controlled manner.
