Abstract
A fuel injector comprising a needle valve and a stop member cooperating with the needle valve. The stop member selectively controls the maximum amount of lift of the needle valve to provide a smaller maximum lift or a larger maximum lift thereof whereby, when the required amount of fuel to be injected by the fuel injector is small, the needle valve is lifted to the smaller maximum lift, and when the required amount of fuel is large, the needle valve is lifted to the larger maximum lift.
