CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

PROBLEM TO BE SOLVED: To prevent a run-on phenomenon at the time of failure of start due to cranking. SOLUTION: When cranking is stopped after failure of start, swing-back of a crankshaft occurs immediately before the stop. Since due to this swing-back, a POS signal is duplicatedly input, there is a...

Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent a run-on phenomenon at the time of failure of start due to cranking. SOLUTION: When cranking is stopped after failure of start, swing-back of a crankshaft occurs immediately before the stop. Since due to this swing-back, a POS signal is duplicatedly input, there is a possibility that simultaneous injection is continued after stop of cranking. In this invention, when intervals of the POS signal are abnormally long, it is determined that swing-back occurs, and ignition is stopped. When a cylinder discrimination error is determined based on the consistency with ignition order of numbers of discriminated cylinders, simultaneous injection is prohibited. Accordingly. the run-on phenomenon by automatic ignition of simultaneously injected fuel can be securely prevented. COPYRIGHT: (C)2005,JPO&NCIPI
