    摘要: A throttle body for an internal combustion engine has a housing, a first plate carried by the housing for linear reciprocation between a first position and a second position in response to movement of a throttle member, and a second plate carried by the housing for linear reciprocation between a first position and a second position in response to the movement of the fist plate. The first plate and second plates define at least in part an opening through the throttle body. The opening provides a variable flow area that increases as the first plate and the second plate move from their first positions toward their second positions and decreases as the first and second plates move from their second positions toward their first positions. As the first and second plates move between their first and second positions, the flow area of the opening is continually varied.

    摘要: A method, fuel system, and components for facilitating the delivery of liquid fuel from a fuel tank in fluid communication with a float bowl carburetor of an internal combustion engine, wherein evaporative emissions of the fuel from the fuel tank and float bowl carburetor are mitigated. During operation of the engine, fluid communication is permitted between the fuel tank and the carburetor, and fuel vapors at a predetermined threshold superatmospheric pressure are permitted to vent outwardly from the fuel tank. During inoperation of the engine, fluid communication is prevented between the fuel tank and the carburetor, and fuel vapors at a predetermined threshold superatmospheric pressure are permitted to vent outwardly from the fuel tank.

    摘要: A method, fuel system, and a valve for facilitating the delivery of liquid fuel and fuel vapors from a fuel tank in fluid communication with a carburetor of an internal combustion engine. During operation of the internal combustion engine, the fuel tank is permitted to fluidically communicate the liquid fuel to the carburetor, and to vent the fuel vapors to one or more of a carbon canister, the atmosphere, and the carburetor. In contrast, when the internal combustion engine is not operating, the fuel tank is prevented from fluidically communicating the liquid fuel to the carburetor, and from venting the fuel vapors to one or more of the carbon canister, the atmosphere, and the carburetor, thereby preventing escape of evaporative emissions of the fuel from the fuel tank.

    摘要: A system for reducing escape to the atmosphere of hydrocarbon fuel vapors from a fuel tank for a combustion engine powered device including at least one functional member that directly communicates with the fuel tank and is constructed to receive and retain hydrocarbon vapors therein. The functional member may further include a bed of activated carbon-based material for adsorbing and purging of the hydrocarbon vapors. The functional member is otherwise useful to the device beyond the vapor handling function and may be incorporated into a handlebar assembly, frame component, housing, cover, and the like thereby reducing component parts and reducing cost and complexity of the device.

    摘要: A modular diaphragm carburetor is provided which has a plurality of plates each with generally planar faces adapted to be mated and releasably connected together to facilitate manufacturing and assembling the carburetor and to permit various plates and components of the carburetor to be used in carburetors designed for use with different engine families. By providing a plurality of mated together plates, the machining of the passages through the carburetor is made dramatically easier when compared to the machining of a carburetor having a single body with end caps. Still further, the modular diaphragm design permits different plates and/or components of the carburetor to be used with other components to provide a carburetor having different performance characteristics and suitable for use with a different engine family. Therefore, a wide range of carburetors can be provided which have many of the same components to reduce the overall part count and to more economically manufacture and assemble a wide range of carburetors.

    摘要: A two stroke combustion engine, equipped with fuel injection apparatus and ignition timing controlled by throttle position, has a charge forming device which delivers a rich fuel mixture from an integral float-type fuel chamber. The fuel injection apparatus typically comprises a tuned injector tube that communicates between a crankcase injector port and a cylinder injector port. The vast majority of fuel mixes with air in an injector mixing passage of the charge forming device where it is subsequently delivered to the tuned injector tube which directly injects the rich fuel mixture into a cylinder of the engine. The rich fuel mixture supplied by the charge forming device injects into the combustion chamber through the cylinder injector port via a reflected pressure wave generated from the previous combustion cycle. A primary air circuit of the charge forming device delivers a substantially lean mixture of fuel-and-air into the crankcase at high engine speeds where it flows from the crankcase through an air feed passage and into the combustion chamber. At idle and low speed engine conditions where throttle position is less than fifty percent open, ignition timing is predominately used to control engine operation. This feature simplifies design and calibration of the charge forming device while improving engine performance at extremely low fuel demands and load conditions.

    摘要: A fuel pump module with a housing which carries a fuel pump and a fuel filter between an outlet of the fuel pump and an outlet of the module housing to filter fuel discharged from the fuel pump before it is delivered under pressure to an operating engine. The fuel filter preferably provides the final filtering of the fuel before it is delivered to the engine and preferably has a large surface area to extend the life of the fuel filter in use. The fuel filter is preferably generally cylindrical and has a casing defining an interior opening in which the fuel pump is received with a seal to prevent fuel leakage between them. Preferably, the components of the fuel pump module are generally telescopically and coaxially fitted together to provide a compact fuel pump module while still providing a large surface area fuel filter.

    摘要: A liquid propane fuel storage and delivery system for a vehicle engine with a fluid handling component module removably top-mounted on an appropriate vehicle-mounted pressurized liquid propane fuel storage tank. The module includes: (1) a fuel tank 80% stop-fill subsystem that automatically opens and closes the tank fill port to control tank fuel fill; (2) a hydrostatic back-check valve to prevent reverse fuel flow from the tank to atmosphere via the fill port; (3) an excess fuel bypass return check valve that maintains a predetermined amount of pressure in the fuel line as required to achieve acceptable engine performance; (4) a return check bypass valve that bypasses the return check valve to allow an extra amount of vapor-purging liquid fuel to be flushed through the system and returned to the tank through the fill solenoid prior to engine start-up; (5) an excess flow valve to limit fuel flow to atmosphere in case of a severed fuel line; (6) a supply solenoid valve assembly that prevents fuel flow to the engine if the solenoid is not energized; (7) a supply line over-pressure check valve to prevent a pump outlet line from being overstressed due to pressure build up; (8) a tank pressure relief valve; (9) a tank drain valve; (10) a "leak-free" electrical coupling; and (11) a fuel pod assembly housing one or two fuel pumps pumping either in parallel or series flow.
