초록 ▼

An air/fuel handling system for a small fuel injected engine with a preferably extruded body having an air tuning chamber, a fuel pump chamber and a fuel rail chamber therein for supplying fuel to one or more fuel injectors. A preferably separate fuel metering and throttle body is mounted on the chamber body. Air is supplied to an intake passage of the throttle assembly to the air chamber which has ram tubes for supplying combustion air to the intake manifold of the engine. Fuel from a remote gasoline tank is supplied through a metering valve assembly to the inlet of an electric fuel pump mounted in the pump chamber which supplies high pressure fuel to the fuel rail and injectors and thus to the engine. Fuel vapor in the metering chamber is separated from liquid fuel and supplied to the air intake chamber when the engine is operating.

대표청구항 ▼

An air/fuel handling system for a fuel injection engine comprising: a body having a fuel chamber, a fuel rail passage having at least one outlet to supply fuel to at least one fuel injector, and an air chamber having an inlet and at least one outlet to supply air to the engine, a fuel pump disposed in said fuel chamber and having a low pressure inlet and a high pressure outlet in fluid communication with the fuel rail passage, a housing connected to said body, a low pressure fuel metering chamber in said housing in communication with said low pressure inlet of said fuel pump, and having a metering valve to control fuel flow from a remote supply to said metering chamber, an air flow passage in said housing communicating with the inlet of said air chamber and having a throttle valve therein to control air flow to said air chamber, and a vapor separator carried by said housing in communication with said fuel metering chamber and the inlet of said air chamber to allow fuel vapor to flow into said air chamber.
