    摘要: A method of operating a turbocharged engine having cylinders in which one of the cylinders undergoes a compression stroke. The method includes advancing an ignition spark in the one of the cylinders undergoing the compression stroke by a first amount relative to top dead center of the compression stroke at a first barometric pressure for a given engine speed and load, and advancing the ignition spark in the one of the cylinders undergoing the compression stroke by a second, lesser amount relative to top dead center of the compression stroke at a second, lower barometric pressure, for the given engine speed and load as the vehicle being at different altitudes.

    摘要: A method for sensing a volume of fluid located in an oil sump of a motor vehicle transmission includes repetitively determining a rate of change of a temperature of the oil, repetitively determining an acceleration of the vehicle, counting the number of occurrences in which said acceleration is greater than a reference acceleration and said rate of change of the temperature is greater than a reference rate of change of temperature, and producing an indication that the volume of fluid is low, if said number is greater than a reference number.
