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.

Filtration systems having a normal filtration mode and an enhanced filtration mode are described. In some arrangements, the filtration system is an air filtration system having a primary air filter element, a pre-cleaner, and a pre-cleaner bypass valve. Based on feedback from an intake air quality sensor the bypass valve is either opened or closed to selectively route intake air through the pre-cleaner during sensed dirty air operating conditions (e.g., heavy dust or moisture concentrations). In other arrangements, the filtration system is a liquid filtration system (e.g., a fuel or oil filtration system) that has a main filter and a secondary filter. The filtration system selectively routes the liquid being filtered through the main filter, the secondary filter, or a combination thereof depending on a detected event or sensed characteristic of the liquid.

Intake bypass flow management systems and methods

An electronic system providing unique identification of a genuine filter system assembly to the engine control unit ('ECU'). A resistor is made to be an integrated part of the filtration system hardware such that when connected through a wired connection, the ECU detects a particular voltage signal and identifies the system as a genuine filter. The resistor could be integrated in any part of the filter system such that it could be used to recognize the filter or the cartridge. The resistor connection could be made via male/female pins, conducting wires, plates, conductive plastic material or other mechanisms.

The application generally relates to digital Engine Integrity Protection (EIP) systems for filters for internal combustion engines and methods of using the digital EIP systems. A pre-programmed digital chip is integrated in filtration hardware such that the Engine Control Unit (ECU) or another controller installed on the engine or vehicle can read encrypted digital signal from the chip when electrically connected with the filter hardware. Based on the read information from the chip, the ECU or controller can determine whether the filter associated with the chip is a genuine filter or a non-genuine filter.

A system and method for determining a condition of a filter filtering fuel associated with an engine. Input information relating to the operation of the engine is provided by a plurality of sensors. At least some of the input information is used to determine a plurality of input variables, the plurality of input variables representing a plurality of engine operating conditions including engine run time, engine torque and engine speed. An algorithm incorporating the input variables is used to determine the condition of the filter. Information concerning the condition of the filter may be output to a user such as an operator or service provider.

Virtual filter condition sensor

An electronic system providing unique identification of a genuine filter system assembly to the engine control unit ('ECU'). A resistor is made to be an integrated part of the filtration system hardware such that when connected through a wired convection, the ECU detects a particular voltage signal and identifies the system as a genuine filter. The resistor could be integrated in any part of the filter system such that it could be used to recognize the filter or the cartridge. The resistor connection could be made via male/female pins, conducting wires, plates, conductive plastic material or other mechanisms.

Methods and systems for estimating the loading of an air filter are disclosed herein. The method includes receiving upstream mass air flow data indicative of a mass air flow on an upstream side of an air filter (i.e., the 'dirty side of the filter'), receiving downstream air pressure data indicative of an air pressure on a downstream side of the air filter (i.e., the 'clean side of the filter'), and receiving downstream temperature data indicative of a temperature on the downstream side of the air filter. The method also includes determining a differential pressure (&#x394;P) across the air filter indicative of a loading of the air filter based on the upstream mass air flow data, the downstream air pressure data, and the downstream temperature data.
