1. A control system for an engine having a plurality of combustion chambers, the control system comprising:
- a plurality of fuel injectors associated with the plurality of combustion chambers; and
a controller in communication with each of the plurality of fuel injectors and being configured to;
determine a need to inhibit fueling of a subset of the plurality of combustion chambers; and
selectively regulate the plurality of fuel injectors to inhibit fueling of a fraction of the subset at a time until fueling of all of the subset has been inhibited.

Abstract
A control system for an engine having a plurality of combustion chambers is disclosed. The control system may have a plurality of fuel injectors associated with the plurality of combustion chambers, and a controller in communication with each of the plurality of fuel injectors. The controller may be configured to determine a need to inhibit fueling of a subset of the plurality of combustion chambers. The controller may also be configured to selectively regulate the plurality of fuel injectors to inhibit fueling of a fraction of the subset at a time until fueling of all of the subset has been inhibited.

11. A method of operating an engine, comprising:
-
injecting fuel into a plurality of combustion chambers; determining a need to inhibit fueling of a subset of the plurality of combustion chambers; and selectively inhibiting fueling of a fraction of the subset at a time until fueling of all of the subset has been inhibited. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A genset, comprising:
-
a generator operable to produce an electrical power output; an engine connected to drive the generator and including; a plurality of combustion chambers; a plurality of fuel injectors associated with the plurality of combustion chambers; a sensor configured to monitor a performance of the engine and generate a signal indicative of the engine performance; and a controller in communication with each of the plurality of fuel injectors and the sensor, the controller being configured to; determine a need to inhibit fueling of a first subset of the plurality of combustion chambers based on the signal; selectively regulate the plurality of fuel injectors to inhibit fueling of a fraction of the first subset at a time until fueling of all of the first subset has been inhibited; determine a need to inhibit fueling of a second subset of the plurality of combustion chambers; and selectively regulate the plurality of fuel injectors to inhibit fueling of all of the second subset and to substantially simultaneously begin fueling of all of the first subset, wherein the number of combustion chambers included within the first subset is equal to the number of combustion chambers included within the second subset.
