Two types of particulate trap systems for heavy duty diesel truck have been newly designed and bench tests were conducted. The first is single wall flow type trap and a burner-assisted regeneration system in which exhaust gas is by-passed during regeneration. Even though maximum temperature in the trap could be kept low by controlling both burner gas temperature and the amount of particulate collection, there was a problem of trap failure, cracks developing after a certain period. The other type is a cross flow type trap where collected particulate is blown out periodically by high pressure air from rear side of trap for burning by an electric heater. This system features that the trap can be regenerated without heating the trap body itself. After conducting basic tests it was found that this system had a high potential. This paper details this new concept.
