Abstract
A fuel injection nozzle is provided with such an annular fuel passage that its fuel passage section is, at the earlier stage of fuel injection, maintained smaller than the whole sum of the sectional areas of injection orifices and adapted to increase gradually in response to the lift of a nozzle needle so that the rate of fuel injection increases gradually.
