Appeal No. 1999-0276
Application 08/283,099
1. 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 (T ) indicative of the sensed engine
c
temperature;
sensing the engine speed and producing an engine speed
signal (S ) indicative of a magnitude of the sensed engine
f
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 (2) representing when fuel is to be injected relative
to (TDC), wherein the magnitude of the timing angle signal (2)
includes a predetermined ignition delay from the time that
fuel is injected to the start of combustion.
The text of the appealed claims is set forth in Appendix A of
appellants' brief.
