    • A method is provided for checking the function of a fuel composition sensor and for learning the percent alcohol content of a fuel used in a motor vehicle capable of operating on more than one type of fuel, as an alternative to a fuel composition sensor. The present invention improves the reliability of a motor vehicle utilizing a fuel composition sensor by allowing vehicle operation to continue uninterrupted, such as when a short or open condition exists within the sensor. The method first determines whether conditions are such that the percent alcohol content of a fuel should be "learned". If conditions are appropriated, then necessary engine operating conditions are first initialized. The oxygen sensor output signal is checked to determine whether the engine is operating too rich or lean. The value of percent alcohol content stored in the engine control unit's memory is modified in the direction of stoichiometric engine operation. In this manner, the engine is able to "learn" the percent alcohol content of the fuel and make the appropriate adjustments to operating parameters.
    • 提供了一种用于检查燃料组成传感器的功能并且用于学习在能够对多于一种类型的燃料进行操作的机动车辆中使用的燃料的百分比酒精含量的方法,作为燃料组合物传感器的替代物。 本发明通过允许车辆操作不间断地继续使用燃料成分传感器的机动车辆的可靠性,例如当传感器内存在短路或打开状态时,可以提高可靠性。 该方法首先确定条件是否应使燃料的酒精含量百分比“学习”。 如果条件被占用,则首先初始化必要的发动机运行条件。 检查氧气传感器输出信号,以确定发动机是否运行太丰富或偏重。 存储在发动机控制单元的存储器中的酒精含量百分比的值在化学计量发动机操作的方向上被修改。 以这种方式,发动机能够“学习”燃料的酒精含量百分比并对操作参数进行适当的调整。
