PURPOSE:To reduce fuel sticking to the inner wall of a suction passage and thereby prevent a catalyzer from being deteriorated or the like, by letting one side of fuel injection valves perform normal fuel injection as long as the specified period at the time of transmission from a high load area to the specified light load driving area. CONSTITUTION:A first fuel injection valve C sprays fuel directly to the inside of a suction passage or a combination chamber. And, a second fuel injection valve D feeds fuel to the inside of the suction passage separated as far as the specified distance from the combustion chamber. And, these fuel injection valves C and D are controlled by a fuel injection controlling device B on the basis of the judged result of a driving load state judging device A, respectively. That is the first valve C performs fuel injection and noninjection at the specified light load area. And, the second valve D performs normal fuel injection at a high load area. In this constitution, at time of transition from the high load area to the specified light load area, there is additionally provided with a fuel injection compensating device E which makes the first valve C perform the normal fuel injection as long as the specified period. With this, fuel sticking to an inner wall of the suction passage is reduced. |
