ABSTRACT Electro-mechanical fuel injection system includes a fuel reservoir, a plurality of fuel injectors, a control valve, a control unit, an injection phasing means having a plurality of valves, a rotor having an orifice, a stator having a plurality of orifices and a plurality of ports. The rotor is rotatably connected to stator and is rotatably driven by the engine and orifice of rotor is operatively provided in fluid communication with orifices of stator. The control unit receives information from a sensor adapted to determine user demand for engine speed and torque of the engine and an engine speed sensor and provides information to control valve to open at a predetermined time and for predetermined duration to allow the flow of fuel from fuel reservoir to orifice in rotor and fuel from orifice in rotor flows to each of the fuel injectors through corresponding orifices of stator and corresponding valves.
