Ceramic Trap Regeneration Rate Control through Bypass Technique 880004

A ceramic trap forced regeneration system for urban buses and passenger cars, capable of safe and reliable on-road regeneration is presented in this paper. Development of this system has been made possible through the application of two main design aims: The possibility of protecting the trap from overheating by use of a trap bypassing technique, and the reduction of the total mass of intervening parts between engine and trap, so as to improve trap temperature transient response.
