Multiple cylinder engine management system
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 at least one running condition by controlling the system associated with at least some of said combustion chambers for precluding combustion therein while maintaining substantially even firing intervals between the combustion chambers and varying the specific combustion chambers which are disabled with time while maintaining the same number of running combustion chambers and maintaining substantially equal firing intervals between those running 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.

- 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 at least one running condition by controlling the system associated with at least some of said combustion chambers for precluding combustion therein while maintaining substantially even firing intervals between the combustion chambers and varying the specific combustion chambers which are disabled with time while maintaining the same number of running combustion chambers and maintaining substantially equal firing intervals between those running combustion chambers.
- 14. An internal combustion engine having a plurality of combustion chambers, an induction system for supplying an air charge to said combustion chambers including a throttle valve for controlling the flow through said induction system, 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 position of said throttle valve under at least one running condition for permitting a greater air flow through said induction system than required to operate said engine at the desired speed for said running condition, and means for controlling the speed of said engine at said one running condition by controlling at least one of the systems associated with at least some of said combustion chambers for precluding combustion therein while maintaining substantially equal firing intervals between said combustion chambers.
- 31. 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 the system associated with at least some of said combustion chambers for precluding combustion therein while maintaining substantially even firing intervals between the combustion chambers and varying the specific combustion chambers which are disabled with time while maintaining the same number of running combustion chambers and maintaining substantially equal firing intervals between those running combustion chambers.
- 52. 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 during at least one running condition by controlling the system associated with at least two of said combustion chambers for precluding combustion therein while maintaining substantially even firing intervals between the remaining combustion chambers and maintaining the same number of running combustion chambers per cycle of said engine.
