摘要： A vehicle liquid testing system includes a liquid testing apparatus with a form factor of a dipstick. The system includes a sensor that detects a property of a fluid in a vehicle and emits a signal indicative of the property. A transmitter receives the signal from the sensor and transmits the signal. A controller receives the signal from the transmitter and compares the signal from the sensor to a threshold level to determine a condition of the fluid.

摘要： A monitoring system includes an analytical engine system coupled to a sensor of an engine system. The analytical engine system is configured to receive data corresponding to operation of the engine system, to determine a distance metric corresponding to the operating parameters of the engine system, to compare the distance metric for a monitored lubricant temperature to a model threshold, and to generate a lubricant alert signal when the distance metric for the monitored lubricant temperature is greater than the model threshold. The received data includes the monitored lubricant temperature of a bearing and operating parameters of the engine system. The distance metric is based at least in part on the monitored lubricant temperature relative to a lubricant temperature statistical model, which is based at least in part on the operating parameters of the engine system.

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： An engine assembly includes an oil pan including an oil pan body defining a cavity. The oil pan body includes a dividing wall separating the cavity into a first compartment and a second compartment. The dividing wall defines a compartment opening extending therethrough, and the compartment opening fluidly interconnects the first compartment and the second compartment. The engine assembly also includes an oil pump at least partially disposed inside the first compartment of the oil pan. The oil pump includes a pump pickup conduit in fluid communication with the first compartment. The engine assembly additionally includes a temperature sensor disposed inside the pump pickup conduit of the oil pump. The temperature sensor can measure the temperature of oil flowing into the oil pump. In other words, the temperature sensor can sense the temperature of the oil pumped in the engine.
