ABSTRACT:
A method of controlling fuel injection in an internal combustion engine including a crankshaft, a fuel injector, and a control unit for outputting a signal causing a fuel injection event, with a minimum time delay between the output of the signal and initiation of the fuel injection event, the method comprising the steps of sensing crankshaft position, outputting the signal, and providing an additional time delay between the output of the signal and initiation of the fuel injection event so that the signal must be output at an earlier crankshaft position than would be necessary without the additional time delay, whereby changing crankshaft speed has a greater effect on the difference between the desired crankshaft position of the fuel injection event and the actual crankshaft position of the fuel injection event.
