Abstract: A cylinder cutout system for an internal combustion engine is provided. The system may include a plurality of cylinders having a first pattern of cylinders and a second pattern of cylinders. Additionally, a fuel governor operatively coupled to a plurality of fuel injectors may regulate an amount of fuel received by the plurality of cylinders. The system may further include a plurality of sensors configured to collect a set of engine data and a controller communicably coupled with the plurality of fuel injectors, the fuel governor and the plurality of sensors. The controller may be programmed to detect a start-up condition of the engine and to execute a cylinder test cycle on at least a portion of the plurality of cylinders based on a positive detection of the start-up condition. The controller may activate one of the first or second patterns of cylinders based on the cylinder test cycle results.
