초록 ▼

A fuel control system is provided including a fuel tank, a purge vapor canister, a vapor line, and a fuel injector connected to an internal combustion engine. A purge vapor canister vent valve seals the purge vapor canister from the atmosphere such that the fuel tank, purge vapor canister, and fuel injector form a closed system. Upon initial starting of the engine, the purge vapor pressure is such that the purge vapor is drawn to the fuel injector from the dome portion of the fuel tank after passing through the purge vapor canister. Simultaneously therewith, the amount of liquid fuel is reducing or increasing by an amount of equally increasing or decreasing, respectively, vapor fuel so that a necessary mass flow rate is achieved to support combustion. As the amount of fuel vapors decreases to a negligible amount, combustion is supported by the atomization of liquid fuel. The delivery of the liquid fuel and vapor fuel is completed through the use of a fuel injector to accommodate both liquid and vapor form of fuel.
