| description | The invention relates to a method and to a device for projecting the failure time of the pressure limiting valve of a high-pressure fuel pump of a motor vehicle. The method has the following steps: measuring a characteristic parameter of the pressure limiting valve after each stoppage of the motor vehicle, determining and storing a variable determined by using the measured characteristic parameter, determining the time profile of the variable determined from the characteristic parameter, predicting the future profile of the variable determined from the characteristic parameter, and comparing the predicted future profile of the variable determined from the characteristic parameter with a predefined wear limiting value to predict the time at which the predicted future profile of the variabledetermined from the characteristic parameter reaches the predefined wear limiting value.
本发明涉及用于预测机动车辆的高压燃料泵的限压阀的失效时间的方法和装置。该方法具有以下步骤：每次机动车辆停止之后，测量限压阀的特性参数，确定并存储通过使用测得的特性参数确定的变量，确定根据特性参数确定的变量的时间曲线，预测根据特性参数确定的变量的未来曲线，以及将根据特性参 |
