Abstract
A method of operating an engine includes determining an intake air temperature and an engine speed. The method includes selectively initiating one of a first operating mode, a second operating mode and a third operating mode based on at least the intake air temperature and the engine speed. The first operating mode includes increasing the engine speed progressively by an incremental speed value. The second operating mode includes deactivating at least one Exhaust Gas Recirculation (EGR) cylinder of the engine. The third operating mode includes shutting down the engine.
