Abstract:
1. A fuel delivery system for an internal combustion engine having at least one cylinder and a piston arranged for movement in the cylinder, the system including; a fuel injector having a body which contains electronic componentry for operating the injector, and an end region from which fuel is delivered for delivering fuel to the cylinder, the end region having an outer surface; means for heating the outer surface of the end region of the injector, but not the body, to thereby heat fuel inside the end region before the fuel undergoes controlled ejection from the injector, so that as soon as the fuel leaves the injector, the fuel substantially immediately converts to vapour state because of the heating of the fuel and the change in pressure experienced by the fuel when the fuel leaves the injector; and a fuel passage extending between the fuel injector and the cylinder for conveying the vapour from the injector to the cylinder so the vapour is maintained in a vapour state as the fuel travels along the fuel passage from the injector to the cylinder.
