Abstract
A fuel injection system for an internal combustion engine is provided for providing an injection event including a first stage and a second stage via a single nozzle. The nozzle is connected by its inlet port to a source of variable fuel pressure and it includes a needle valve for performing the first stage of injection, and a poppet valve for performing the second stage of injection. The first and second stages of injection are selectable by controlling the fuel pressure in the inlet port which is common for both the needle valve and the poppet valve.
