  • Method and system for controlling a turbocharged two stroke engine based on boost error
    Patent number: 11828239
    Abstract: A method and system for controlling a wastegate comprises determining a boost pressure target, measuring a boost pressure, determining a boost pressure error from the measured boost pressure and the boost pressure target, determining a wastegate position change based on boost pressure error, and changing the wastegate position corresponding to the wastegate position change.
    Type: Grant

  • Method and system for controlling a two stroke engine based on fuel pressure
    Patent number: 11815037
    Abstract: A method and system for operating a two-stroke engine includes a fuel system comprising a fuel pressure sensor, fuel temperature sensor and a fuel injector and a controller in communication with the fuel pressure sensor and fuel temperature sensor. The controller controls the fuel injector with a fuel pulsewidth determined by determining a beginning time of a window for measuring fuel pressure, determining an ending time of the window, measuring fuel pressure between the beginning time and the ending time, determining a fuel pulsewidth based on the fuel pressure and fuel temperature and injecting fuel into the two-stroke engine in response to a desired fuel mass.
