    • An improved system for automatically continuously replacing an engine's used lubricating oil with fresh lubricating oil throughout operation based on engine operating conditions is disclosed. The present system includes an intermittent injection control device for intermittently injecting small amounts of used lube oil into the engine's fuel system. An electronic controller is provided to vary the amount of used lube oil injected into the oil system based on the severity of engine operation. The system periodically determines an engine operating severity value, i.e. fuel consumption value, for an interval of engine operation and calculates a base line quantity of oil for injection based on the current fuel consumption of the engine during the current interval. The system may also include an auxiliary flow control device for directing controlled quantities of fresh oil into the engine's lube oil system for maintaining the engine's oil sump at a proper level. The system maintains the quality of the engine lube oil at a level necessary to provide optimal engine protection at all engine operating conditions while also maintaining the oil concentration in the engine's fuel at an acceptable level.

    • An improved method and system for automatically continuously replacing an engine's used lubricating oil with fresh lubricating oil throughout operation based on engine operating conditions is disclosed. The present system includes an lube oil replacement pump system operable in a replacement mode for injecting small amounts of used lube oil into the engine's fuel system and directing controlled quantities of fresh oil into the engine's lube oil system to replace the removed oil. The process periodically determines an engine operating severity value, i.e. fuel consumption value, for an interval of engine operation and calculates a base line quantity of oil for injection based on the current fuel consumption of the engine during the current interval. The lube oil replacement pump may also be operated in a makeup mode for adding quantities of fresh oil to the engine lube oil sump to compensate for oil consumed by the engine. The system adjusts the quantity of used oil to be removed and injected based on the quantity of fresh oil supplied during the makeup mode to prevent overreplacement of the lube oil. The lube oil pump system may be in the form of a compact, unitized lube oil replacement pump assembly integrating the various components of the system. The system maintains the quality of the engine lube oil at a level necessary to provide optimal engine protection at all engine operating conditions while also maintaining the oil concentration in the engine's fuel at an acceptable level.

    • A system and method for indicating when the oil of an engine needs to be changed. The system includes measuring engine parameters such as engine temperature, fueling rate, engine speed, and engine load. At timed intervals, soot generation, viscosity increase, and total base number (TBN) depletion are estimated through a calculation for that time interval. The estimated values from the calculations are accumulated in separate loops. Once the accumulation of soot generation, oil viscosity increase, or TBN depletion reaches a predetermined magnitude for that respective oil property, then an indication or signal is provided to indicate to the engine operator that the oil needs changing. The system is supplemented with real time sensors such as an oil level sensor, a soot sensor, and a viscosity sensor which provide a back up for the calculation of estimates and also prevent catastrophic engine conditions from not being detected through electronic calculation of estimates. The system and method also can correct for the accumulation of oil consumption caused by evaporation of oil or leakage of oil. The algorithms used in the calculations can account for oil quality and fuel sulfur as well as the configuration of the engine, to allow the engine to be used in different geographic locations.
    • 一种用于指示何时需要改变发动机油的系统和方法。 该系统包括测量发动机参数,如发动机温度,加油速率,发动机转速和发动机负荷。 按照时间间隔,通过计算该时间间隔估计烟炱产生,粘度增加和总碱值(TBN)耗尽。 来自计算的估计值累积在单独的循环中。 一旦烟灰产生的累积,油粘度增加或TBN耗尽达到相应油性质的预定量级,则提供指示或信号以向发动机操作者指示油需要改变。 该系统补充有实时传感器,例如油位传感器,烟尘传感器和粘度传感器,其提供用于估计的计算的备份,并且还通过电子计算估计来防止未检测到灾难性的发动机状况。 该系统和方法也可以纠正油蒸发或油渗漏引起的油耗累积。 计算中使用的算法可以解释油质和燃料硫以及发动机的配置,以允许发动机在不同的地理位置使用。
