  • Genset engine with an electronic fuel injection system integrating electrical sensing and crank position sensing
    Patent number: 8683980
    Abstract: An open or closed loop EFI system, integrated on a genset engine or any internal combustion engine, with an electrical sensor and crank position sensor is described. Since a genset engine's exhaust emissions and general performance are a function of spark timing, integration of electrical and crank position sensors on a genset engine provides optimal engine performance and efficiency when the electrical draws fluctuate. The electrical sensor and crank position sensor send data to the electronic control unit (ECU), and this data is used to determine the optimal air-to-fuel ratio (AFR) and optimal spark timing. The ECU varies the spark timing in accordance with the speed and load of the engine and actuates the fuel injector to send the correct amount of atomized fuel to mix with the air flow to be combusted allowing the engine to meet performance.
