Abstract
A fuel induction system for an internal combustion engine which includes a throttle valve that is positioned substantially open under idle and near idle engine running conditions. The system includes means for disabling one or many of the cylinders in order to maintain a low engine rotational speed at idle and near idle and also means for selectively disabling the cylinders in such a manner as to provide the smoothest running engine possible in those instances where one or many of the engine's cylinders are disabled.
