STEUERVORRICHTUNG FUER DIE KRAFTSTOFFEINSPRITZMENGE VON ALKOHOLMOTOREN
摘要
A fuel injection control device is provided for a flexible fuel vehicle alcohol engine to be driven with a mixed fuel consisting of gasoline and alcohol. The engine includes a port injector provided at each cylinder and an intake pipe assembly portion injector commonly provided for all the cylinders. The control device defines such a fuel injection pulse width as enabling the operation of the injector in dependency on the alcohol density and the engine state. It drives only the intake pipe assembly portion injector to inject the fuel if the pulse width is smaller than a predetermined value or adds the fuel injection of the port injector to that if it is larger.
