Abstract: Methods and systems are provided for operating an engine having a plurality of cylinders that utilize oil for lubrication purposes. In one embodiment, a method for the engine may include determining if one or more conditions have been met for port heating based on one or more operating conditions of the engine, continuing current operation if the one or more conditions for port heating have not been met, and determining a souping level of the engine if the one or more conditions for port heating have been met and subsequently running port heating on a set of cylinders of the engine based on the souping level of the engine and/or the one or more conditions for port heating. The engine may be a non-EGR engine and/or a high speed diesel engine. Each cylinder of the set of cylinders may have at least one port.

Abstract: Systems and methods for operating an engine and controlling engine parameters over a range of ambient temperature conditions are provided. A method for an engine includes selecting one or more of an engine speed, an engine load, a base timing, and a fuel common rail pressure from a pre-calibrated engine map corresponding to a selected throttle level and modifying the one or more of the engine speed, the engine load, the base timing, and the fuel common rail pressure based on sensed environmental conditions.
