PURPOSE: To obtain an air intake heating system and a method for heating intake air for assisting cold weather starting of engines as well as for minimizing white smoke pollutants produced by diesel engines after starting of the engine and as required thereafter during engine operation. CONSTITUTION: The system described includes a microprocessor based controller 25, an intake manifold 30 air temperature monitoring means 28, and an engine speed monitoring means 36. The controller 25 controls the energizing of electrical air heating elements 54, 56 in response to various combinations of sensed engine speed, sensed intake manifold air temperature and sensed battery condition 27. |
