Abstract
A Diesel particulate trap oxidiser system suitable for retrofiting on urban buses is described. The system consists of a ceramic trap, a regeneration device and a control unit.
The system is based on a new forced regeneration technique, by means of exhaust gas throttling. This technique establishes regeneration conditions on the road by the engine itself, with-out any external source of thermal energy or catalyst.
Two buses in use with the Athens Public Transport Company (EAS) have been equipped with this system. The buses have been tested under real conditions on Athens urban bus routes and the results after the first 10000 km of operation are presented.
