1. A system, comprising:
a non-EGR high speed diesel engine having sets of cylinders, each cylinder having at least one port; and
a controller with instructions stored in memory and configured for:
determining one or more operating conditions of the engine;
determining a load of the engine;
determining if one or more conditions have been met for port heating based on the one or more operating conditions of the engine and the load of the engine;
