    摘要： A system is provided for calibrating a position sensor having a variable output corresponding to the variable position of a movable member. The system establishes, for the position sensor an original assumed output corresponding to a given position of the movable member, establishes for the position sensor a maximum output corresponding to the given position, the maximum output being greater than or equal to the assumed output, establishes for the position sensor a minimum output corresponding to the given position, the minimum output being less than or equal to the assumed output, determines an actual output of the position sensor and, if the actual output is between the maximum output and the minimum output, the system reestablishes the assumed output as being a function of the original assumed output and the actual output.

    摘要： A fuel-injection system for an internal combustion engine that operates in a stratified mode of fuel injection during a first engine speed range and a homogeneous mode of fuel injection during a second engine speed greater than the first range. A changeover speed is determined for a particular engine and, upon speed (or load) increasing to the point of changeover from the stratified mode, the engine speed update point changes from a first or "standard" update point to a second predetermined "provisional" update point for one or two revolutions after which the update point then reverts back to the "standard" update point.

    摘要： A method for calibrating an electronic control unit for an internal combustion engine. The electronic control unit may have multiple channels with each channel being adapted to provide an input drive signal to a fuel delivery apparatus. A first channel is selected for calibration. A reference signal of desired and known parameters is also defined. The reference signal is defined such that it is indicative of the cyclical performance of a fuel delivery apparatus such as a fuel injection device. A command signal is generated and passed through the circuitry of the selected channel. The channel circuitry generates a drive signal in response to the command signal. A desired parameter of the drive signal is measured for comparison with the known parameter of the reference signal. If necessary, the command signal is then adjusted so as to produce a modified drive signal which has a parameter with reduced variation from the known reference parameter.
