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.

Disclosed are systems, methods, and algorithms for monitoring and indicating filter life. In particular, the disclosed systems, methods, and algorithms may be utilized for monitoring and indicating the useful life of a filter in an internal combustion engine.

System for monitoring and indicating filter life

An upper endcap of a fuel filter cartridge includes a skirt, an axially extending pin surrounded by the skirt, and a plurality of ribs that define fluid flow channels leading to the pin. The pin is extendable through an axially facing fuel inlet opening at the upper end of a standpipe for actuating a valve to an open position allowing fuel to flow through the axially facing inlet opening and into the standpipe. The valve can include a hole that receives the pin therein to help stabilize the valve when the valve is actuated open.

No filter no run fluid filtration system

A connection between a fluid filter and a head is described that permits quick connection/disconnection between the two without requiring disconnection of fluid lines from the head. The head includes a lock to connect inlet and outlet fluid lines to a fluid filter using a non-threaded attachment method. The lock that retains the head to the fluid filter is flexible to allow for connection and disconnection. The head has fluid inlet and outlet ports to which fluid lines attach to flow unfiltered fluid into and filtered fluid out of the fluid filter when the head is connected to the fluid filter. The head closes the fluid filter, which has a protrusion with adjacent passageways that guide and separate unfiltered from filtered fluid.

Fluid filter and head with quick connector

Systems, methods, and algorithms for monitoring and indicating filter life of an internal combustion engine, hydraulic systems, and other machines are useful. The systems, methods, and algorithms may be used to provide an indication alert to a user that the filter is approaching an end-of-useful-life condition.

Improvements to 'no filter, no run' fluid filtration systems are described. In one example, a filter includes a movable pin cage that has a first pre-installation position adjacent the bottom end plate and is temporarily connected thereto by a snap connection system, and a second position adjacent the upper end plate where it performs a valve interaction function. In another example, a filter includes non-centered valve pins that are rotatable relative to an upper end plate of the filter.

No filter no run fluid filtration systems

Various 'no filter, no run' fuel filtration designs are described that include a variable restriction orifice (VRO) designed to vary the amount of fluid, for example fuel, that reaches a fluid outlet. The VRO has a fully open position at which a maximum non-zero fluid flow is permitted, and a fully closed position at which a limited amount of fluid can flow to the outlet. In the case of diesel fuel, the amount of fuel flow permitted at the fully closed position provides lubrication of downstream fuel system components, for example the fuel pump, but is insufficient to permit engine operation.

Filtration system with a variable restriction orifice

A filter is described that is combined with a device to address vibrations. Such vibrations can adversely impact filter performance. An engine system including this combination is also described.

Filter system with vibration dampening

A parallel flow filter-in-filter design for a filter system is provided. The filter-in-filter design provides two distinctly parallel or independent flow paths within a filter assembly in a single housing or shell. The filter assembly includes a first outer filter element radially spaced apart from a second inner filter element. A centertube and a funnel shaped passageway housed within the centertube are provided in a space between the first outer filter element and the second inner filter element. The centertube and funnel shaped passageway work in tandem to provide two distinct parallel or independent flow paths within the filter assembly. The funnel shaped passageway is provided generally below the second inner filter element within the centertube.
