Fuel control for multi-cylinder engine
First Claim
1. An internal combustion engine having a plurality of combustion chambers, an induction system for supplying an air charge to said combustion chambers, a charge forming system for supplying fuel to said combustion chambers for combustion therein, an ignition system for igniting the charge in said combustion chambers for effecting combustion therein, means for controlling the speed and/or power of the engine during at least one range of operation by controlling the number of combustion chambers in which combustion takes place, and means for varying another of the systems of the combustion chambers in which combustion is taking place in a manner to provide an offsetting change in engine speed and/or power to reduce the magnitude of the variation in engine speed and/or power change.

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. Smooth transition from one mode to another is achieved by fuel and ignition corrections.
