475 results about "Airbox" patented technology

An airbox is an empty chamber on the inlet of most combustion engines. It collects air from outside and feeds it to the intake hoses of each cylinder. Older engines drew air directly from the surroundings into each individual carburetor. Modern engines instead draw air into an airbox, which is connected by individual hoses to each carburetor or directly to the intake ports in fuel-injected engines, thus avoiding an extra intake manifold.

Air inlet for ATV

An all terrain vehicle has a frame assembly. A pair of front wheels and a pair of rear wheels support the frame assembly. A front fender assembly extends over at least a portion of the front wheels. An engine is disposed between the front wheels and the rear wheels. The engine is water-cooled using a radiator and fan combination that is positioned forward of the engine. A belt drive forms a portion of a transmission that transfers power from the engine to at least the rear wheels. The belt drive is air cooled with air that is pulled into the belt drive by fans positioned within a belt case. The air is drawn from an air chamber formed within the front fender assembly. The chamber is positioned vertically higher than the radiator and fan combination and rearward thereof. The air passes between the chamber and the belt case through a duct. The duct extends downward and incorporates a central trap portion. The duct is positioned to lie at least partially within an area that overlaps the fan from a front elevation view. The duct also bends across a central longitudinal plane from inlet to outlet to allow a compact configuration while positioning the duct in protected regions.

Supercharger with housing internal noise attenuation

A positive displacement supercharger includes a housing defining a rotor cavity with a pair of positive displacement rotors operative to carry air axially from an inlet end to an outlet in the cavity wall near an outlet end of the cavity. The outlet communicates with an outlet plenum partially defined by the cavity wall. The cavity wall includes a stiff portion defining a plurality of lightening recesses, such as a waffle pattern, limiting distortion of the wall by pulsations in the plenum. The recesses may be time and cost efficiently converted to Helmholtz tuners by covering the recesses with a cover plate, which may be perforated to include at least one tuning opening (perforation) into each tuning chamber (recess) and forming tuning volumes of the tuning chambers and their associated tuning openings effective to attenuate selected frequencies of pulsations in the plenum and thereby reduce undesired noise emanating from the air system of the supercharger.

Canopy air delivery system

An area air delivery system for delivery of filtered air to an area occupiable by a user who can enter and leave the area, such as the head end of a bed, includes a canopy for at least partially surrounding the area to which air is to be supplied and defining the area which a user can enter and leave. An air diffuser positioned in the canopy includes a housing having an air impervious rear wall, air impervious side walls, and a perforated front wall forming a plenum in which a filter bag resides. The plenum is connected to a source of pressurized, preferably prefiltered, air so that pressurized air is supplied to the interior of the filter bag to diffuse through the filter bag into the plenum. Perforations in a predetermined area of the perforated front wall of the housing allow air to flow through the perforations and provide a substantially even flow of air from the perforated front wall of the diffuser into the canopy.

Intake manifold

A bolt-on replacement intake manifold has an asymmetrical plenum with a first end including an inlet, a closed terminal end, a concave top surface and a convex bottom surface; a flange; and a plurality of runners extending from the bottom surface of the plenum and terminating at the flange. The plenum defines an interior space in flow communication with the runners. The bottom surface of the plenum is wider than the top surface. The plenum initially widens from the inlet to the first runner and then begins to narrow from the first runner toward the last runner adjacent to the closed terminal end. The runners are tapered, curved, and vary in length. The intake manifold causes air to exit each of the plurality of runners at substantially the same angle. The manifold balances airflow across each runner and increases swirl inside the cylinders enhancing fuel economy, power output, and torque.
