Abstract

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.

Claims15

Dependent claims

An apparatus, comprising:

an internal combustion engine having an engine control module structured to control the operation of the internal combustion engine;
an air filtration system having a first filter cartridge;
a fluid filtration system having a second filter cartridge
a first pressure sensor structured to sense a characteristic associated with the air filtration system;
a second pressure sensor structured to sense a characteristic associated with the fluid filtration system;
a filtration monitoring system module including a processing circuit communicatively coupled to the sensor, the processing circuit including a processor and memory, the processing circuit structured to:
receive a feedback signal from each of the first pressure sensor relating to the characteristic associated with the air filtration system and the second pressure sensor related to the characteristic associated with the fluid filtration system,
analyze the feedback signals to determine a status of each of the first filter cartridge and the second filter cartridge,
calculate a percent loading of each of the first filter cartridge and the second filter cartridge, and
transmit each of the percent loading of the filter cartridges to the engine control module;
and
wherein the engine control module is structured to transmit, via a telematics system, batch data comprising the status and the percent loading of each of the first filter cartridge and the second filter cartridge.

A method of installing a filtration monitoring system for an internal combustion engine, the method comprising:

providing a filtration monitoring system module having a processing circuit structured to:
receive a first feedback signal from a first pressure sensor associated with an air filtration system associated with the internal combustion engine, analyze the first feedback signal to determine a status of a first filter cartridge of the air filtration system, and calculate a percent loading of the first filter cartridge, and
receive a second feedback signal from a second pressure sensor associated with a fluid filtration system associated with the internal combustion engine, analyze the second feedback signal to determine a status of a second filter cartridge of the fluid filtration system, and calculate a percent loading of the second filter cartridge;
connecting the filtration monitoring system module to the first pressure sensor and to the second pressure sensor;
providing an engine control module having a processing circuit structured to transmit, via a telematics system, batch data comprising the status and percent loading of the first filter cartridge and the status and percent loading of the second filter cartridge;
and
connecting the filtration monitoring system module to a vehicle bus such that the filtration monitoring system module can communicate data to and from an engine control module of the internal combustion engine.
