Abstract: A fuel injector has an injector nozzle with nozzle body having internal room and nozzle wall hole connecting this room to exterior of the nozzle body. A valve needle is movable in a longitudinal direction and received in the internal room. The valve needle has an internal fuel channel with inlet located at a circumferential surface of a first portion. The nozzle wall hole has a circular cross-section with the same diameter as the first valve needle portion defined by walls extending in parallel with the longitudinal direction of the needle. The fuel inlet of the fuel channel is located on said walls of the nozzle wall hole in a second position to prevent fuel entering the fuel channel and located inside the internal room in a first position for receiving fuel from this internal room and injecting it into a combustion chamber of a cylinder of an engine.
