Abstract
Particulate regeneration technique has been improved under consideration of preventing excess heat and stable regeneration.
Effort has been paid for these considerations, and tests under vehicle operating condition are considered to be important for more actual use. Electric heater is selected for the current regeneration heat supply under consideration of compactness and cost for light heavy duty diesel truck.
Parameters which should be controlled at regeneration are particulate loading, supplied air flow rate, air flow distribution and heated trap inlet temperature.
Initial trap inlet temperature affects internal trap temperatures and their distribution during regeneration.
Results of vehicle evaluation on road and short durability test on chassis dynamometer are included, and required improvements are discussed.
