A fuel injector includes an injector housing having an inlet and a plurality of discharge orifices. The inlet permits fuel to flow into the injector housing, and the plurality of discharge orifices permit fuel to flow out of the injector housing and into the combustion cylinder. A first variable restriction in the injector housing variably controls the flow of fuel to the plurality of discharge orifices. A second variable restriction in the injector housing variably controls the flow of fuel to the first variable restriction. The first and second variable restrictions independently control momentum and flow rate of the fuel.
