Abstract
In a fuel injection system for an engine, the degree of opening of a throttle valve provided in the suction pipe is detected with a throttle valve sensor. When the load of the engine is smaller than a predetermined value, a control unit operates to close an electromagnetic valve provided in a bypass passageway of the suction pipe, thereby setting the flow rate of air in the bypass passageway to zero or an extremely small value, whereby, when the load of the engine is higher than the predetermined value, the quantities of exhaust gases of hydrocarbon and carbon monoxide are reduced, and when the engine is under a light load, the fuel consumption is reduced.
