    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 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 fuel system for a fuel injected internal combustion engine has a liquid-cooled fuel pump which draws fuel from a liquid-vapor separator and delivers it under pressure to the engine at a rate higher than that necessary to operate the engine. Preferably, a fuel pressure regulator downstream of the fuel pump and adjacent the engine bypasses excess fuel to a return fuel chamber in communication with the liquid-cooled fuel pump to cool the return fuel before it is returned to the liquid-vapor separator. Reducing the temperature of the returned fuel before it is discharged into the liquid-vapor separator reduces the generation of vapor in the liquid-vapor separator thereby enabling use of a smaller, less expensive vapor separator. Reducing the amount of fuel vapor in the system is desirable because the fuel vapor can decrease the efficiency and life of the fuel pump and is environmentally hazardous.

    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 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.
