Patent ID: 8683980

Claim:
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, wherein the electrical sensor is configured to read an electrical output from an alternator, the electrical sensor is configured to read a power draw on the genset engine, the crank position sensor is configured to read a position of a piston, the electronic control unit is configured to (1) receive data from the electrical sensor, crank position sensor, and air flow sensor via the first, second, and fourth communication circuitry, respectively, (2) determine a spark timing based on the crank position sensor which is transmitted to an ignition system to change a spark timing of the engine, (3) determine a requested relative air to fuel ratio based on the data received from the electrical sensor and the air flow sensor, and (4) actuate the fuel injector via the third communication circuitry based on the determined requested relative air to fuel ratio and the spark timing.
