Abstract:
A method for electronically controlling the timing of fuel injection to start an internal combustion engine (55), comprising the steps of:sensing the temperature of the engine (55) and producing a temperature signal (Tc) indicative of the sensed engine temperature; sensing the engine speed and producing an engine speed signal (Sf) indicative of a magnitude of the sensed engine speed; and receiving the engine speed and temperature signals, determining the start of injection to cause combustion at substantially Top Dead Center (TDC) based on the magnitude of the engine speed and temperature, and producing a timing angle signal (&thgr;) representing when fuel is to be injected relative to (TDC), wherein the magnitude of the timing angle signal (&thgr;) includes a predetermined ignition delay from the time that fuel is injected to the start of combustion.
