Abstract: A gas-liquid separator has a housing having an inlet for receiving a gas-liquid stream and an outlet for discharging a gas stream. A nozzle structure in the housing has a plurality of nozzles that receive the gas-liquid stream and accelerate the gas-liquid stream therethrough to create a plurality of gas-liquid jets. An inertial collector in the housing causes a sharp directional change of the gas-liquid jets, causing separation of liquid particles from the gas-liquid stream to produce the gas stream. The inertial collector has a porous collection substrate. According to the present disclosure, at least one of the following three conditions is met: (a) the porous collection substrate comprises fibers of small diameter and has low packing density: (b) the porous collection substrate comprises oleophobic fibers; and (c) the nozzle structure and the inertial collector are configured to allow for full expansion of the plurality of gas-liquid jets.

Abstract: A system for providing air to an internal combustion engine comprises a crankcase ventilation unit that receives unrefined blowby gas from a crankcase, separates oil from the unrefined blowby gas, and discharges refined blowby gas. A conduit delivers the refined blowby gas to an air cleaner housing. The air cleaner housing comprises a first chamber that receives intake air through a first port, a second chamber that receives intake air from the first chamber and refined blowby gas from the conduit through a second port, and a third chamber that receives a mixture of intake air and refined blowby gas from the second chamber and discharges the mixture through a third port. A primary filter element filters the intake air as it passes from the first chamber to the second chamber. A secondary filter element filters the mixture as it passes from the second chamber to the third chamber.

Abstract: A thermal recirculation valve (TRV) is described that provides for effective fuel module heating during cold operation to mitigate fuel waxing or gelling issues. The TRV allows for the control of heated return fuel flow into the module dependent upon the module's outlet fuel temperature without the return fuel directly contacting the wax element. The wax element is isolated from direct contact with the higher temperature return fuel through use of an elastomeric seal which prevents return fuel from directly contacting the wax element. In addition, the wax element is positioned in the fuel outlet of the module.

Abstract: A filter element for fuel, oil or other engine fluids, with an endplate that is designed to create flow paths for both clean and dirty regions. The filter element is part of a spin-on filter that is attachable to a filter head in an engine and that filters fuel, oil or other engine fluids. A pre-fill cap can be integrally incorporated onto the endplate to permit pre-filling and installation without removing components.

Abstract: 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.

Abstract: A filter assembly comprises a housing defining an internal volume. The housing defines an outlet. A housing ledge extends radially inwards from a rim of the outlet. An outlet conduit comprises an outlet elbow, and an outlet tube extending axially from the outlet elbow towards the housing. The outlet tube is positioned within the housing. A rib extends radially from an outer surface of the outlet tube proximate to the outlet elbow. The rib engages the housing ledge so as to couple the outlet conduit to the housing. A filter element is also positioned within the housing.

Abstract: Panel filter elements having a pleat block and a seal member are described. The panel filter elements are arranged such that the seal members and pleat blocks can have curved and/or angled elements. The seal member of a filter element may be curved, angled, twisted, and/or has a varying cross-section. The inlet and outlet faces of the pleat block of the filter element may be curved and/or twisted instead of planar. In some arrangements, both the seal member of the filter element and the faces of the pleat blocks can be curved and/or twisted. The described filter elements may be may be flexible, such that the shape of the filter element and/or seal can conform to the shape of a filter housing, or rigid, such that the shape of the filter element remains substantially the same before and after installation into a filter housing.
