A filter monitor system ('FMS') module is installed on the engine/vehicle and is connected to the filter systems, sensors and devices to monitor various performance parameters. The module also connects to the engine control module (“ECM”) and draws parameters from the ECM. The FMS module is capable of interfacing with various output devices such as a smartphone application, a display monitor, an OEM telematics system or a service technician's tool on a computer. The FMS module consists of hardware and software algorithms which constantly monitor filter systems and provide information to the end-user. FMS module provides necessary inputs and outputs for electronic sensors and devices.

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.

Fluid quality monitoring and filtration system

Disclosed are methods, systems, and computer-readable mediums for determining combustion properties of wellhead gas. A methane concentration of a gas mixture is measured. A non-methane hydrocarbon concentration of the gas mixture is measured. An inert concentration of the gas mixture is calculated. A first surrogate for the non-methane hydrocarbon concentration is selected, where the first surrogate is selected as propane if the methane concentration is greater than a first threshold, and where the first surrogate is selected as pentane if the methane concentration is less than or equal to the first threshold. A methane number of the gas mixture is determined, where the methane number is based on the methane concentration, the first surrogate, and the inert concentration.

Systems and methods for determining combustion properties of wellhead gas

A process, system, and component configuration are described that discourages customer acceptance/use of will-fit, reconditioned, and counterfeit product components, by determining whether or not a serviceable product component is genuine. If a component is determined to not be genuine, then appropriate action may be taken to warn operators and document such findings. For example, one or more markers are disposed or otherwise put on the subject serviceable product component and serves as a targeted feature, and/or a particular characteristic of the filter itself is identified as the targeted feature. A sensor is used to detect the targeted feature and obtain information unique to the serviceable product component. The targeted feature(s) identifies the particular serviceable component as genuine and forms the basis for determining whether a genuine component has been installed. In some circumstances, a fluid filter product is the component that is the subject detection.

Apparatus, system and method for detecting the presence of genuine serviceable product components

A method includes providing an exhaust stream for an internal combustion engine, where the exhaust stream is fluidly coupled to an aftertreatment component. The method includes optically determining an amount of an exhaust gas constituent in the exhaust stream. The method further includes modifying a model stored on a computer readable medium in response to the amount of the exhaust gas constituent. The model is an engine NOgeneration model, a catalyst NOstorage model, a catalyst NOconversion model, a catalyst NO to NOconversion model, a catalyst conversion efficiency model, an engine soot generation model, and/or a urea hydrolysis model.

Apparatus, system, and method for aftertreatment control and diagnostics

A run-safe filter system is provided for confirming installation of a qualified filter element in a housing. An electrical switch has a first electrical condition in response to a qualified filter element being installed in the housing, and a second electrical condition in response to the absence of a qualified filter element installed in the housing.

Run-safe filter system

A method and system for improving sensor accuracy of diesel emissions is disclosed. The method and system change the sensor reading as a function of sensor age to provide a more accurate measure of the diesel emissions. By estimating the degree of sensor error and then providing a gain correction factor as a function of sensor age, a more accurate measure of the diesel emissions is provided.
