Abstract
The invention is a method for a cylinder cutout system in a compression ignition engine utilizing a plurality of electronic unit injectors. An electronic controller, in communication with the compression ignition engine, is configured to receive a plurality of sensor signals indicative of current engine operating parameters. In response to the received signals, the electronic controller produces an injector signal. Included in each of the electronic unit injectors is a solenoid, that when activated in response to the injector signal received from the electronic controller, will facilitate injection of fuel to a corresponding cylinder. A predetermined plurality of the electronic unit injectors will be deactivated in response to the injector signal.
