Abstract
Real world driving conditions and tightening legislations require improved performance of aftertreatment systems at lower temperatures. Electric heat has been shown to be an effective method of heating exhaust, but having a practical means to provide power and control for the heater has been a barrier for implementation. Recent testing has demonstrated the ability of a 24Vdc heating and control system to effectively heat exhaust using only conventional alternator and battery power sources. Results from transient cycles show the effectiveness of the electrical system and the extent of exhaust heating.
