    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： Methods and fuel systems to reduce evaporative emissions of a volatile fuel. A fuel tank contains fuel, a carburetor mixes air with the fuel from the fuel tank, and a plurality of fluid paths route fuel amongst and/or between the fuel tank and the carburetor. A valve actuation device stops flow of fuel in one or more of the plurality of fluid paths and the carburetor is adapted to be drained of fuel during engine shutdown to reduce or prevent evaporative emissions from the fuel system. The carburetor is preferably designed so as to minimize a volume of fuel contained therein.

    摘要： A fuel evaporative emission control apparatus in a carburetor which prevents diurnal evaporation to the atmosphere of fuel from a remote fuel tank through a fuel bowl or fuel chamber of a float-type carburetor. One or more shut-off valves in the carburetor are yieldably biased to a shut-off position. Only upon engine operation or user intervention will the fuel shut-off valve move to an open or on position. In this way, reliance upon the engine user is not required to reduce evaporative emissions.

    摘要： A carburetor having a first valve to control the application of pressure pulses to a fuel metering assembly of the carburetor through a first flow path and a second valve which controls at least a second flow path to provide an enriched fuel and air mixture to the engine to facilitate starting the engine and warming it up. The pressure pulses are preferably applied to a fuel metering diaphragm to actuate the diaphragm and cause a richer than normal fuel and air mixture to be delivered to the engine. Desirably, a maximum enrichment of the fuel and air mixture is obtained when at least one valve is open to facilitate starting the engine, and a lesser enrichment of the mixture may be obtained by closing a valve to facilitate warming the engine up after it is initially started.
