Abstract
PURPOSE: To perform the injection of fuel synchronously with the opening of intake valve by controlling the opening and closing of one or several injectors provided to intake pipe by a pulse signal of crank angle, etc.
CONSTITUTION: The fuel injector 16 and the auxiliary injector 17 are provided the intake pipe 19 on the downstream side of the throttle valve 23, and the fuel of the fuel tank 26 is supplied through the fuel pump 24 and the fuel pressure regulator 25 into the both injectors 16 and 17. The controller 10, into which signals from the crank angle sensor 12, the intake sensor 13, the intake temperature sensor 14, the cooling water sensor 15, and the throttle valve opening sensor 27 are put, controls on the opening and closing of the injectors 16 and 17 synchronously with the intake valve to cause fuel to inject according to operational condition. Furthermore, the by-pass 28 having the electromagnetic valve 18 and going around the throttle valve 23 is provided and at the same time the amount of air flowing through the pass 28 is corrected.
