摘要： A method and apparatus of controlling the direct injection of fuel directly into the combustion chamber of an engine by a charge of gas, wherein the control of the timing of injection of the fuel includes at the commencement of start up of the engine, adjusting the timing of injection so injection occurs at a timing earlier in the combustion chamber cycle than the normal timing of injection for idle running; and in response to the engine reaching a predetermined speed or rotation during start up, the timing of injection is progressively adjusted each engine cycle towards the normal timing of injection at idle running.
