ABSTRACT:
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.
