Abstract
An air or air/fuel throttling body contains a main air or air/fuel induction passage with a main rotatable throttle plate movable across the passage to variably control the flow through it. Additionally, a shuttle type slide valve is mounted on the main throttle plate and provided with openings that are adapted to be aligned or misaligned at times with apertures in the main throttle plate to control the flow of an additional volume of air or air/fuel through the throttle valve into the engine regardless of the attitude or position of the main throttle plate and supplementing the flow normally passing around the throttle plate; the shuttle valve being moved by power means energized by an electrical signal from a microprocessor having inputs sensing operating conditions of the engine to position the slide valve to maintain an idle speed schedule.
