  • Intake bypass flow management systems and methods
    Patent number: 10668414
    Abstract: 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 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.

  • Installation of correct filter cartridge in fluid filter assembly before allowing assembly to be completed
    Patent number: 10603613
    Abstract: The descriptions relate to preventing assembly of a fluid filter apparatus unless a filter cartridge is installed, and preventing assembly of a fluid filter apparatus if the incorrect filter cartridge is installed. A mechanism includes cooperation of a movable member and a structure that can move the movable member to ensure that a fluid filter apparatus cannot be completely assembled, for example connecting its filter head to its shell, when there is no cartridge installed inside the shell or when there is an attempt to install an incorrect cartridge. This can protect from an inadvertent or intentional failure to install a cartridge (or correct cartridge) in the fluid filter apparatus.

  • Air induction systems for internal combustion engines
    Patent number: 10544759
    Abstract: Air induction systems are for an internal combustion engine. The air induction systems comprise an air intake plenum that conducts intake airflow to an air cleaner for cleaning prior to combustion in the internal combustion engine. The air intake plenum is movable with respect to the air cleaner between an open position separated from the air cleaner and a closed position connected to the air cleaner. A bellows connects the air intake plenum to the air cleaner when the air intake plenum is in the closed position. The bellows has an upstream first end that seals with the air intake plenum and a downstream second end that seals with the air cleaner. A spring is disposed in the bellows. The spring applies a biasing pressure on the bellows that encourages sealing between the bellows and at least one of the air intake plenum and the air cleaner when the air intake plenum is in the closed position.

  • Systems and methods for utilizing a low-friction rotating coalescer contact seal
    Patent number: 10537842
    Abstract: Rotating coalescer crankcase ventilation (CV) systems are described. The described CV systems utilize a contact seal to seal a gap between a static side of a housing and a rotating coalescer inlet. The rotating coalescer may be driven mechanically, electrically, hydraulically, or the like. The contact seal can be formed via a soft solid or a liquid film created by oil. Accordingly, the contact seal is a hydrodynamic soft seal. The contact seal prevents the blowby gases from bypassing the filter element of the rotating coalescer. At the same time, the contact seal may be broken during positive blowby gas recirculation circumstances because the contact seal is a hydrodynamic soft seal.
