Document Type and Number:
Japanese Patent JPH01195949
Kind Code:
A
Abstract:
PURPOSE:To prevent the after-fire at the time of the intake stroke by having an interruption means interrupt subsequent fuel supply when an identification means decides an abnormal cylinder identification within the specified period after an engine starts operation. CONSTITUTION:A controller 11 receives the pulse signal from Karman's voltex flow meter 6 and sends the frequency of the pulse to a micro-computer 12 via a counter 14. The controller 11 also receives the SGC and SGT from a crank angle sensor 8 and sends the frequency of them to the micro-computer 12 via a counter 17. The micro-computer 12 operates the quantity of fuel supply and the ignition timing and compensates them according to the output of a throttle opening sensor 7 and a battery voltage VB. The compensated quantity of fuel supply and ignition timing are set for primary to fourth timers 18 to 21 and the fifth to sixth timers 26 and 27, respectively. When the micro-computer 12 decides the abnormal cylinder identification within the specified period after an engine starts, the subsequent fuel supply is interrupted. The after-fire at the intake stroke is eliminated and the damage to the engine be prevented.
