摘要： Systems, methods, and computer-program products for fluid analysis and monitoring are disclosed. Embodiments include a removable and replaceable sampling system and an analytical system connected to the sampling system. A fluid may be routed through the sampling system and data may be collected from the fluid via the sampling system. The sampling system may process and transmit the data to the analytical system. The analytical system may include a command and control system to receive and store the data in a database and compare the data to existing data for the fluid in the database to identify conditions in the fluid. Fluid conditions may be determined using machine learning models that are generated from well-characterized known training data. Predicted fluid conditions may then be used to automatically implement control processes for an operating machine containing the fluid.

摘要： A system, a method and a computer program to predict a portion of used lubricant in an engine that is to be drained and replaced by fresh lubricant based on an analysis parameter value that is measured in a sample of used engine lubricant from the engine. The system includes a first input that receives the analysis parameter value from the used lubricant and stores the analysis parameter value in a memory of a processor. A second input receives an analysis parameter threshold value for the used lubricant at the end of a service interval and stores the analysis parameter threshold value in a memory of the processor. A determiner predicts a future analysis parameter value of the used lubricant at the end of the service interval based on the analysis parameter value, and the analysis parameter threshold value.

摘要： An apparatus for diagnosing lubricant degradation includes a soot amount estimator configured to estimate an amount of soot formed in a predetermined period in a combustion chamber of an engine, and diagnoses the degradation of a lubricant based on a cumulative value of the amount of soot estimated. The soot amount estimator calculates the amount of soot based on a speed of the engine and a load parameter related to a load of the engine, and corrects, based on a temperature parameter correlated to the temperature of the combustion chamber, the amount of soot calculated into an increased value if the temperature parameter is lower than a predetermined first temperature.

摘要： The oil of a diesel engine is exchanged for each running at a predetermined distance. The oil exchange is carried out by estimating the amount of soot generation by combustion based on a running distance, and is not very accurate. The oil is exchanged earlier. Therefore, the oil is consumed wastefully and a cost of maintenance is increased. There has been found a phenomenon (correlation) in which the degree of oil degradation in the diesel engine is determined depending on an injection end point in such an injection way as to cause the injection end point to be earlier than a specific point (TB) and is determined depending on the injection amount after the specific point and the injection end point in such an injection way as to cause the injection end point to be later than the specific point. When the amount of soot generation is obtained by utilizing the phenomenon, the degree of oil degradation can be obtained more accurately than that in the conventional art. In every fuel injection, it is judged whether the injection end point is set before or after the specific point (Step 8), and a current injection degradation value is obtained by using a corresponding map (Step 9, 10). A cumulative added value is obtained to judge the oil degradation.
摘要翻译：柴油发动机的油以预定距离进行每次运转。油交换是通过基于行驶距离估计通过燃烧产生烟灰的量进行的，并且不是很准确。油更早更换。因此，油被浪费地消耗，并且维护成本增加。已经发现了这样一种现象（相关性），其中根据喷射终点，使得喷射终点比特定点（TB）早的柴油机中的油分劣化程度确定。并且取决于在这样的注入方式下的特定点和注射终点之后的喷射量，以使喷射终点晚于该特定点。当通过利用该现象获得烟炱产生量时，可以比常规技术更准确地获得油劣化的程度。在每次燃料喷射中，判断在特定点之前或之后是否设定了喷射终点（步骤8），并且通过使用对应的图来获得电流喷射劣化值（步骤9,10）。获得累积附加值以判断油的退化。

摘要： A method for performing condition-based maintenance of an engine is presented. The method includes obtaining one or more parameters corresponding to the engine. Also, the method includes determining a temperature profile corresponding to a portion of a fluid flow component based on a first parameter and one or more thermal models. The method further includes estimating a solid deposit in the portion of the fluid flow component corresponding to each cycle of the engine based on the temperature profile and deposition kinetics parameters. Further, the method includes predicting a total solid deposit in the portion of the fluid flow component based on the estimated solid deposit corresponding to each cycle of the engine. Moreover, the method includes performing the condition-based maintenance of the engine based on a value of the predicted total solid deposit.
