    • An upper level sensor or the like is used to detect an amount of lubricant in an oil pan of an engine. When the amount of lubricant exceeds a prescribed value (step ST1), that is, when lubrication of a sliding portion such as a bearing is insufficient due to dilution of the lubricant with fuel, control for lowering engine output such as control for lowering a maximum combustion pressure (step ST3) is carried out, so that combustion load applied to the sliding portion such as a bearing is suppressed when the maximum combustion pressure is attained and seizure of a connecting rod bearing or the like is prevented.
    • 上位传感器等用于检测发动机油盘中的润滑剂的量。 当润滑剂的量超过规定值(步骤ST1)时,即当由于润滑剂被燃料稀释而使诸如轴承的滑动部分的润滑不足时,控制用于降低发动机输出的控制,例如降低最大值 燃烧压力(步骤ST3),从而当达到最大燃烧压力并且防止连杆轴承等的卡住时,能够抑制施加到诸如轴承的滑动部分的燃烧负荷。

    • A method for determining a fuel-dilution condition of a lubricant used in transportation and industrial equipment. The method uses apparatus that applies a high frequency and optionally a low frequency oscillating signal to electrodes immersed in the fluid and quantifies fluid response to the signals. Apparatus can further include means to control the lubricant temperature, or a temperature sensor to monitor the lubricant temperature at the electrodes. The method monitors response of the lubricant to the applied electrical signals and determines ratios of lubricant properties. The high-frequency lubricant property ratio or change of high frequency lubricant property as a function of a lubricant use-measure is compared to a predicted ratio based on lubricant use and an estimate of the lubricant's fuel dilution determined. The optional low-frequency lubricant property ratio is compared to thresholds to determine when the lubricant loses the ability to control fuel dilution. The method outputs information relevant to the fuel-dilution condition of the lubricant.
    • 用于确定运输和工业设备中使用的润滑剂的燃料稀释条件的方法。 该方法使用对浸在流体中的电极施加高频和可选的低频振荡信号并量化对信号的流体响应的装置。 装置还可以包括控制润滑剂温度的装置,或温度传感器来监测电极处的润滑剂温度。 该方法监测润滑剂对所施加的电信号的响应并确定润滑剂性质的比例。 将高频润滑剂性能比或作为润滑剂使用措施的函数的高频润滑剂特性的变化与基于润滑剂使用的预测比和所测定的润滑剂燃料稀释度的估计进行比较。 将可选的低频润滑剂性能比与阈值进行比较,以确定润滑剂何时失去控制燃料稀释的能力。 该方法输出与润滑剂的燃料稀释条件相关的信息。
