Systems and methods are provided for in-situ determination of engine oil viscosity to allow for selection of an engine map by an engine control module (ECM) to match the detected viscosity. The new engine map selected based on the viscosity can correspond to an engine map based on an engine oil with a different HTHS viscosity than the prior engine map. Instead of requiring a reprogramming of an ECM when the engine oil is changed, an ECM can have access to a plurality of engine maps corresponding to different engine oils at a given HTHS viscosity and/or at different HTHS viscosities. The ability of an ECM to select an engine map corresponding to a different HTHS viscosity based on in-situ viscosity detection can allow the oil in an engine to be changed without requiring access to the ECM for reprogramming.

A device for determining fluid degradation includes a memory and processing circuitry configured to cause the device to generate first calibration data of an e-machine at a first time, generate second calibration data of the e-machine at a second time subsequent to the first time, and determine that the fluid is degraded in response to a difference between the first calibration data and the second calibration data being greater than or equal to a degradation threshold.

A system for distributing semisolid lubricant, including a semisolid lubricant tank and a high pressure pumping system that intermittently feeds, during a lubrication cycle, at least one first duct, the at least one first duct feeding a plurality of distributors adapted to sort the semisolid lubricant to a plurality of users; a controlled suction/delivery device, fluidly associated with the first duct, for controlled suction/delivery of a part of the semisolid lubricant conveyed by the first duct. The controlled suction/delivery device configured to suck a volume of semisolid lubricant from the first duct during a step of inactivity of the pumping system on the first duct, and to introduce the previously suctioned semisolid lubricant in the first duct during a step of activity of the pumping system on the first duct.

A fluid condition monitoring device includes a sensing assembly including a sensor and a transducer, the sensor to sense a property of the fluid and the transducer to apply a test signal to the fluid and receive a return signal from the fluid; a control assembly coupled to the sensing assembly, the control assembly including a controller and an input/output interface, the controller interfacing with the transducer to generate fluid condition information in response to the return signal; and an interface assembly coupled to the control assembly, the interface assembly including a connection to the input/output interface to transmit the fluid condition information to an external system.

A lubricant pump (14) and a method thereof are disclosed. The lubricant pump (14) includes a pump base (32) and a reservoir housing (30). The pump base (32) and the reservoir housing (30) define a lubricant reservoir for storing lubricant. One or more pump elements (34) extend at least partially into the lubricant reservoir. Heaters (36) are disposed on the pump base (32) proximate the pump elements (34). The heaters (36) are configured to heat the local area surrounding the pump elements (34), to thereby reduce the viscosity of the lubricant at the pump elements (34). The heaters (36) are electrically connected to a thermal switch (38) to control activation and deactivation of the heaters (36). With the lubricant pump (14) and the method thereof, the thermal switch (38) can control the heater (36) based on air temperature rather than the temperature of the lubricant, so the viscosity of lubricant is well controlled.

An emergency lubrication device of simplified architecture for a mechanical system. The emergency lubrication device has a tank, trigger means, at least one pipe, and at least one distribution means. The tank contains a lubrication liquid and it is arranged inside the mechanical system and above the pipes and the distribution means. Each distribution means includes at least one constriction means for limiting the flow rate of the lubrication liquid. The lubrication liquid is heated by the mechanical system, and the viscosity of the lubrication liquid decreases so that the flow rate of the lubrication liquid through each distribution means is substantially equal to or greater than a minimum flow rate so long as the tank contains the lubrication liquid.

A method, comprising: setting an engine intake airflow parameter based on an engine oil viscosity index. In this way, engine operating conditions that depend on engine friction and engine intake airflow, such as engine idling speed and engine friction torque, may be determined and implemented with an increased consistency. This in turn may decrease the possibility of engine stalls and improve engine performance, particularly at low temperatures.
