ABSTRACT:
A fuel injection device comprising a fuel pump, a constant pressure valve and a fuel nozzle connected to the fuel pump via a fuel feed passage. The constant pressure chamber of the constant pressure valve is arranged in the fuel feed passage. A flow control valve is arranged in the fuel feed passage between the constant pressure chamber and the fuel nozzle. The amount of the fuel injected from the fuel nozzle is controlled by the flow control valve so as to be directly proportional to the amount of the air sucked in. The constant pressure chamber is connected to the fuel nozzle via a bypass passage. An electromagnetic valve is arranged in the bypass passage and opened when an engine is accelerated and before the completion of the warm-up of an engine.
