Abstract: A fuel injector for delivering fuel to an internal combustion engine includes a nozzle having a valve needle which is movable with respect to a valve needle seat. The valve needle travels through a range of movement between a closed position and an open position to control fuel delivery through at least one nozzle outlet. The valve needle cooperates with a needle sleeve or a control member which is located in a piston guide. The valve needle is movable relative to the needle sleeve or the control member. The needle sleeve or the control member is movable relative to the piston guide.

Abstract: Fuel injection equipment includes a high pressure fuel source able to flow high pressure fuel via connecting pipes to a plurality of injectors. The fuel injection equipment is high pressure fuel reservoir-less, a distributed storage for high pressure fuel being arranged in the pipes and in the injectors.
