Control for injected 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, and means for controlling the speed of said engine at least one running condition by controlling at least one of the systems associated with at least some of said combustion chambers for precluding combustion therein and upon resumption of combustion in at least some of said combustion chambers the supply of fuel is gradually returned to a normal amount supplied when the speed is controlled by other than precluding combustion in some combustion chambers.

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 transitional control is achieved by varying ignition and/or fuel control.

- 17. A method of operating 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, said method comprising the steps of controlling the speed of said engine at at least one running condition by controlling at least the charge forming system associated with at least some of said combustion chambers for precluding combustion therein by reducing the amount of fuel supplied by said charge forming system and upon resumption of engine operation when the speed is not controlled by precluding combustion in some of said combustion chambers the supply of fuel is gradually returned to the normal amount.
