FUEL INJECTION CONTROL SYSTEM FOR INTERNAL COMBUSTION ENGINE EQUIPPED WITH EXHAUST TURBOOCHARGER

摘要

PURPOSE:To prevent occurrence of knocking effectively, by determining the extent for increasing fuel supply depending on the pressure difference at the inlet side and outlet side of a suction blower. CONSTITUTION:Throttle opening detector 32 and differential pressure detector 33 are connected to fuel increasing circuit 46 at its input terminals to which charging current is supplied. When the throttle opening detector 32 is turned ON with the throttle valve being opened to a position beyoud a predetermined opening or otherwise when the differential pressure detector 33 is turned ON with the differential pressure on the inlet side and the outlet side of suction blower 10 becoming greater than a predetermined level, current is supplied to an input terminal of circuit 46, whereby the amount of fuel ejected from fuel injection valve 18 is increased.
