  • Engine speed stabilization using fuel rate control
    Patent number: 7130736
    Abstract: Idle speed stability is imparted to a compression ignition engine by processing data values for actual engine speed and desired engine speed to yield a data value for engine speed error; processing (22) the data value for engine speed error according to a governor algorithm for yielding a data value for a mass fuel rate for governed fueling of the engine; c) processing (24) the data value for mass fuel rate for governed fueling of the engine and the data value for actual engine speed to yield a data value for a quantity of fuel to be injected into an engine cylinder during an ensuing stroke of a piston within the cylinder; and d) injecting (30) that quantity of fuel into the cylinder during that stroke.

  • Cold start pulse width compensation
    Patent number: 6618665
    Abstract: An internal combustion engine control system processes data to develop desired fueling data representing a desired amount of fuel that is to be injected into the engine for combustion. The desired fueling data is modified by a multiplier during a cranking, starting, and initial running phase of the engine, and after the engine has started and begins running, modifies the multiplier by a multiplier adder. Use of the multiplier added is discontinued once the engine fuel injectors have sufficiently warmed up. The multiplier adder is a function of an average of desired fueling data taken over a time interval that includes engine cranking, starting, and initial engine running.
