1. A genset engine integrating an electronic fuel injection system comprising:

  • an electrical sensor;

    a crank position sensor;

    a fuel injector;

    an electronic control unit;

    an air flow sensor;

    a first communication circuitry linking the electronic control unit and the electrical sensor;

    a second communication circuitry linking the electronic control unit and the crank position sensor;

    a third communication circuitry linking the electronic control unit and the fuel injector; and

    a fourth communication circuitry linking the electronic control unit and the air flow sensor,the electrical sensor reads an electrical output from an alternator,the electrical sensor reads a power draw on the genset engine,the crank position sensor reads a position of a piston,data from the electrical sensor, crank position sensor, and air flow sensor are transmitted to the electronic control unit via the first, second, and fourth communication circuitry, respectively,the electronic control unit obtains a spark timing based on the crank position sensor which is transmitted to an ignition system to change a spark timing of the engine, anddata form the electronic control unit, based on the electrical sensor and the air flow sensor, is used to obtain a requested relative air to fuel ratio,wherein the electronic control unit actuates the fuel injector via the third communication circuitry based on requested relative air to fuel ratio and the spark timing.
