A method and system that monitors various functions and criteria within a standard vehicle platform (SVP) or a small engine platform (SEP). The SVP uses an OBD-II adapter as a central controller to collect the information and communicate with a mobile communication device or a cloud based application to monitor the health of in-vehicle systems within the SVP and determine if maintenance is required. The SEP utilizes a run hour meter to collect information and communicates with a mobile communication device, an OBD-II adapter, or a cloud based application to monitor the health of an engine within the SEP and determine if maintenance is required. The method and system can automatically dispatch maintenance resources if maintenance is deemed necessary, thereby providing a managed maintenance solution for either a SVP or SEP.

Provided is an oil deterioration diagnosis device capable of detecting oil deterioration accurately and early in real time during operation of an operating machine without oil sampling. An oil deterioration diagnosis device 10 for a construction machine including an oil hydraulic circuit 1 includes: a floodlight projector 11a configured to irradiate oil flowing through the oil hydraulic circuit 1 with measuring light having a predetermined wave number or wavelength during operation of the construction machine; a photoreceiver 11b configured to receive transmitted light having penetrated the oil; a signal processing unit 11c configured to continuously or intermittently measure absorbance or transmittance; and a diagnosis unit 12 configured to detect a decrease of an antioxidant contained in the oil or an increase of a peroxide contained in the oil, based on changes in the absorbance or the transmittance.

A system includes a sensor configured to be in contact with lubricant within an engine of a vehicle system. The sensor includes a sensing region circuit that is configured to generate stimuli at different times during an operational life of the engine. The system also includes one or more processors configured to receive signals from the sensor. The signals are representative of responses of the lubricant to the stimuli. The one or more processors are configured to analyze the responses and determine a characteristic of the lubricant that represents one or more of a total base number (TBN) or a total acid number (TAN) of the lubricant. The one or more processors are configured to determine an unhealthy state of one or more of the engine or the lubricant based on the characteristic of the lubricant that is determined.

Methods of evaluating mixing are disclosed relating to the preparation and mixing of materials. Materials prepared may transition from heterogeneous mixtures to homogenous mixtures while the current of a motor is monitored. Quantities relating to the rate of change of power or the rate of change of entropy may be calculated in evaluating the sufficiency of mixing. Methods of evaluating lubricant degradation are also disclosed.

A filtration monitoring system is an electronic system control module installed on an internal combustion engine or within a vehicle powered by the internal combustion engine. The filtration monitoring system monitors the health and status of the filtration systems present on the engine. The filtration monitoring system tracks filter loading patterns and predicts remaining service life of the filters by running smart algorithms based on sensor feedback (e.g., pressure sensor feedback, fluid quality characteristic sensor feedback, etc.). In some arrangements, the described filtration monitoring systems provide feedback as to whether a genuine (i.e., authorized, OEM approved, etc.) or unauthorized filter cartridge is installed in a given filtration system. The filtration monitoring system may be retrofit into an existing internal combustion engine or vehicle that does not already have a filtration monitoring system.

A method according to an exemplary aspect of the present disclosure includes, among other things, periodically adjusting powertrain operation of an electrified vehicle equipped with an internal combustion engine to progressively influence oil quality of oil of the internal combustion engine.

A fluid filtration system may include a fluid filter assembly that includes a filter element configured to filter a fluid and a sensor probe incorporated into the fluid filter assembly. The sensor probe may include a chemically reactive material sensitive to at least one property of the fluid and at least a portion of the sensor probe may be exposed to the fluid.

A lubrication/bleeder fitting (10) is provided including a cap (14), a body (12) having a first end (15) coupled to the cap, a second end (17) opposite the first end, and an axially extending cavity (40) extending between the first and second ends. The fitting also includes a poppet seat (50) in the axially extending cavity and a poppet (60) disposed in the axially extending cavity and having a nose portion to seat against the poppet seat. A resilient member (64) is disposed in the axially extending cavity between the poppet and the second end, and a spacer (66) is disposed in the axially extending cavity and seating an end of the resilient member opposite the poppet. The poppet is biased in a first position against the poppet seat by the resilient member to prevent fluid flow through the axially extending cavity.
