ABSTRACT:
Engine air flow is controlled by principal and supplementary throttles--the principal throttle being positioned by a stepper motor but also having a mechanical linkage to assure at least partial throttle opening when required, and the supplementary throttle being positioned by a mechanical linkage to permit primary control of engine output by the principal throttle while assuring that engine output is minimized when required.
