PURPOSE:To reduce the number of injectors by providing a single injector body with two fuel injection outlet separately in two directions with each injection outlet equipped with a needle valve with one needle valve being made to synchronize with the stop action of one of suction valves. CONSTITUTION:When a 2nd suction valve 18b stops during operation under low loads, pulse signals from a control unit 22 to a needle valve 6b corresponding to the suction valve 18b are stopped by a signal from a valve stop detection part 23. Accordingly, the needle valve 6b closes a fuel injection outlet 9b by means of a spring 11b. Therefore, as a 1st suction valve 18a only opens and closes to suck air, fuel is supplied from a fuel injection outlet 9a toward a suction valve 18 by means of a needle valve 6a of an injector 1. And when a 2nd suction valve 18b also opens and closes during operation under loads of more than a specified value, pulse signals are inputted also to the needle valve 6b to inject fuel out of a fuel injection outlet 9b. |
