A fuel atomizer that includes a housing having a fuel inlet and at least one primary orifice positioned at the inlet, wherein the at least one orifice configured to disperse a stream of fuel into a plurality of fuel droplets. The plurality of fuel droplets contact a fuel impingement surface to break up the plurality of fuel droplets into a plurality of smaller secondary droplets and create a thin film of secondary droplets on the impingement surface. At least one pressurized air channel delivers an airflow into contact with the secondary droplets. The secondary droplets pass through a plurality of secondary outlet orifices to exit the housing. A size of the plurality of secondary droplets is reduced when passing out of the plurality of secondary orifices.

This supercharger for a motorcycle is driven by power of a crankshaft of a combustion engine, and compresses intake air to be supplied to the combustion engine. The supercharger has an impeller of a centrifugal type, and an intake air control valve is disposed on the upstream side of the impeller of the supercharger with respect to a flow direction of the intake air. The intake air control valve is disposed so as to face a suction port of the supercharger in the flow direction of the intake air. The intake air control valve adjusts the amount of the intake air flowing into the impeller, and in addition, provides a preswirl to the intake air flowing into the impeller.

A throttle body fuel injection system and method that is arranged to easily replace four-barrel carburetors includes a throttle body assembly with four main bores, each with a throttle plate and an associated fuel injector. Each injector feeds fuel into a circular fuel distribution ring via a fuel injection conduit, which introduces pressurized fuel into the air stream. The fuel distribution rings and bores have profiles that avoid constrictions for to prevent low pressure zones according to the Venturi effect. Fuel is injected through downward-facing outlets at or near the bottom end of the rings. The fuel injection rings are two-piece, each formed of an insert pressed into an outer housing. The insert includes axial grooves intervaled about its exterior circumference of insert that are joined by a circumferential groove formed about the insert. The grooves are in fluid communication with a conduit that supplies fuel from a fuel injector.

The present invention relates to a valve for controlling the volume and flow characteristics of a fluid in a predictable controllable manner. Specifically, the invention relates to an air valve design for an internal combustion engine throttle body that proportionately manages air flow, pressure, and velocities through all stages of opening with consistent and measurable parameters through a concentric or near-concentric opening.

A liquid-gas separation unit of a dual-fuel engine is provided. The liquid-gas separation unit includes an exhaust conduit and a separator mounted on the exhaust conduit. The exhaust conduit has a first end and a second end distal to the first end. The first end of the exhaust conduit is coupled to a gaseous fuel supply conduit of the dual-fuel engine for receiving a leaked liquid fuel and a gaseous fuel. The leaked liquid fuel is received from at least one injector of the dual-fuel engine. Further, the separator is adapted to separate the leaked liquid fuel from the gaseous fuel before ejecting the gaseous fuel through the second end of the exhaust conduit.
