  • Preignition mitigation strategy for gaseous fuel engine
    Patent number: 11920528
    Abstract: Operating a gaseous fuel engine system includes detecting preignition in one or more of a plurality of cylinders based on a monitored cylinder pressure during combustion of a gaseous fuel such as a gaseous hydrogen fuel. Operating a gaseous fuel engine system also includes reducing a fuel injection amount for the one or more of the plurality of cylinders to a derated fuel injection amount that is based on a timing of the detected preignition. Fuel injection amount may be reduced to a greater relative extent if detected preignition is early, and to a lesser relative extent if detected preignition is later, in an engine cycle. Related apparatus and control logic is also disclosed.

  • Object profile sensing
    Patent number: 8109007
    Abstract: A method for sensing an object profile shape involves relatively sweeping (whisking or translating) in angular or translational increments an elongated whisker element having a deflectable cantilever region and an object so that the cantilever region bends as a result of sliding along an object periphery. The moment (torque) at a base region of the whisker element as a result of the bending is determined. The method then iteratively determines successive contact point locations on the object periphery based on small successive increments in angle or position of the whisker element and the sensed moment (torque).
