An air valve and its method of use including an air valve housing; a throttle plate disposed on a throttle shaft; a driven gear attached on the throttle shaft; a brushless direct current motor assembly in connection via a pinion with the driven gear; an integrated electronic valve controller including digital signal processing on a circuit board; and a throttle position sensor on the circuit board, wherein the throttle position sensor includes at least one non-contact type sensor. In a preferred embodiment, the air valve includes an inlet port and an outlet port connected to an engine via an air intake manifold, such that re-circulated exhaust gas is introduced into the air intake manifold.

Air valve and method of use

This invention is directed to a dual barrel carburetor for a motorcycle. The preferred carburetor includes a novel combination of a fuel bowl assembly, a metering assembly, a main body assembly, and an air plenum assembly. The dual barrel carburetor includes annular discharge booster venturis associated with a main fuel delivery circuit. An idle circuit opens downstream of the throttle plates. A transfer circuit discharge port is positioned across the throttle plates. The combination of the idle, transfer and main fuel circuits ensures the smooth delivery of fuel throughout all operating conditions of the motorcycle engine. The plenum manifold assembly includes a pair of air passages in fluid communication with one another to permit a final opportunity to optimize the fuel delivery to the respective combustion chambers.
