  • Publication number: 20170122152
    Abstract: An apparatus and a method are provided for a high capacity oil filter configured to remove contaminants from engine oil flowing within an internal combustion engine. The oil filter comprises a hollow canister having a length and a diameter suitable for housing a large filtration medium. A base gasket forms a fluid-tight seal between the oil filter and the engine. A base plate circulates oil from the engine through the oil filter. An anti-drainback valve prevents oil from draining out of the filter and passages within the engine when the engine is not operating. A key aspect of the present disclosure is that the relatively large dimensions and the configuration of the filtration media provide a large surface area for entrapping contaminants flowing with the engine oil.

  • Publication number: 20170122270
    Abstract: An apparatus and methods are provided for an air cleaner to be mounted onto an air inlet of an internal combustion engine. The air cleaner comprises an air filter that includes a filter medium disposed between a curved base and a cover. The curved base provides an interface between the air filter and the air inlet, and comprises a shape that provides clearance between the curved base and an electric choke installed onto a carburetor comprising the air inlet. The cover secures the air filter and the curved base to the air inlet such that an airstream is drawn through the filter medium and is conducted into the air inlet. A raised portion of the cover is configured to cooperate with the curved base to ensure a desired volume of the airstream is available to the air inlet at substantially all engine speeds.

  • Publication number: 20170122183
    Abstract: An apparatus and a method are provided for a water neck for use with a water pump to circulate a coolant from a radiator to an LS engine. The water neck comprises a conduit which includes an interior opening to convey the coolant by way of a water hose to the radiator. The conduit includes a cylindrical section having a smooth exterior surface and a circumferential edge that are configured to receive the water hose. A base is configured to be coupled with the water pump, such that the coolant is conveyed from the water pump through the water neck. A supportive section interconnects the conduit and the base, and orients the conduit relative to the base so as to direct the conduit and the water hose away from the LS engine and a belted pulley assembly of the LS engine.

  • Patent number: 9605627
    Abstract: An apparatus and a method are provided for an air filter cleaning wand for flushing contaminants from an intake air filter of an automobile engine. The air filter cleaning wand comprises a proximal flange, a conduit, and a distal end portion. The proximal flange is configured to receive a nozzle of a water hose. An interior of the conduit is in fluid communication with the proximal flange. The distal end portion comprises a plurality of longitudinally aligned vents in fluid communication with the interior of the conduit. Upon passing water through the water hose and into the conduit, pressurized water streams exit the vents along the distal end portion so as to flush contaminants from the air filter. The air filter cleaning wand advantageously is comprised of a material which is sufficiently durable and temperature resistant to retain its configuration during operation when coupled to pressurized water sources.

  • Patent number: 9587535
    Abstract: An apparatus and method are provided for a drone elimination muffler to attenuate drone exhibited by engine exhaust systems. The drone elimination muffler comprises a hollow canister having a length and a diameter, and a tuned port comprising a first end connected to the canister and a second end connected to the exhaust system. The canister operates in concert with the tuned port as a dampener configured to substantially attenuate exhaust drone, or resonance, at one or more frequencies of engine operation. A valve is configured to switch the drone elimination muffler between a closed state in which the exhaust system operates without acoustic influence due to the drone elimination muffler, and an open state in which the drone elimination muffler directly influences the acoustic properties of the exhaust system.

  • Patent number: 9581111
    Abstract: An apparatus and method are provided for a fuel bowl to supply liquid fuel to a carburetor. The fuel bowl comprises a float chamber and a fuel inlet cavity which receives a fuel delivery insert. The fuel delivery insert receives a fuel inlet valve and comprises passages to direct incoming fuel to a bottom portion of the float chamber. A float comprises an elongate member rotatably hinged within a float cavity of the fuel delivery insert, such that the float rises according to a quantity of fuel within the float chamber. The fuel inlet valve supplies liquid fuel to the float chamber by way of the passages according to the operation of the float within the float chamber. A ventilation chamber allows air and fuel vapors to exit as liquid fuel enters the float chamber while preventing liquid fuel from entering into the carburetor.

  • Publication number: 20170021298
    Abstract: An apparatus and a method are provided for a heating, ventilation, and air conditioning (HVAC) home air filter to remove airborne molecular contaminants and volatile organic compounds (VOCs) from air within residential spaces. The HVAC home air filter comprises a supportive frame having a shape and size suitable to orient the HVAC home air filter within a residential HVAC system. A filter medium is retained within the supportive frame to remove the airborne molecular contaminants and VOCs from air flowing through the residential HVAC system. The filter medium comprises a combination of media layers configured to exhibit a relatively high filtration efficiency and a low air pressure drop across the filter medium. The supportive frame comprises a plurality of elongate sections and corner sections disposed along perimeter edges of the filter medium to support the filter medium within the residential HVAC system so as direct air through the filter medium.

  • Publication number: 20150314227
    Abstract: A filter oil composition and a method for removing airborne molecular contaminants from air are provided. The composition includes a first portion comprising paraffinic oil by volume of the composition, a second portion comprising polyalphaolefin (PAO) by volume of the composition, and a third portion comprising red dye by volume of the composition. Applying the filter oil composition to a cotton air filter material causes tackiness throughout the air filter material, thereby enhancing filtration of air passing through the filter. The composition generally is substantially non-reactive, has an excellent oxidation stability, possesses good thermal stability, and retains a suitable viscosity at a normal operating temperatures of an automobile engine. In an embodiment, the composition comprises 96.74% paraffinic oil by volume, 3.20% polyalphaolefin (PAO) by volume, and 0.06% red dye by volume. A viscosity of the composition at 100 degrees-C ranges between substantially 7.2 and 7.6 centistokes (cSTs).
