ABSTRACT:
A fuel injection system comprises a fuel injection valve of the fuel swirling type which is provided in an intake passage upstream of an intake valve that is arranged in an inlet port, the fuel injection valve being equipped with an adapting device for adapting the form of the fuel spray, which is injected through the fuel injection valve in a swirling manner, to the configuration of the inlet port as seen from the position where the fuel injection valve is mounted. With this structure, the fuel can be prevented from impinging on the upper and lower walls of the inlet port, thereby preventing the fuel injected into the combustion chamber forming a liquid film. This helps to enhance the combustion efficiency of the associated internal combustion engine and to reduce the HC content in the exhaust gas, thereby improving the starting performance at low temperature of the engine.
