TRIAL OF PARTICULATE TRAPS FOR HEAVY DUTY VEHICLES WITH DIESEL ENGINES. FINAL REPORT
ERPROBUNG VON RUSSFILTERN FUER SCHWERE DIESELFAHRZEUGE. SCHLUSSBERICHT
Five city buses and heavy duty trucks were equipped with different particulate traps and tested over a period of up to two years. The particulate traps were catalytic trap oxidisers without any special mean of regeneration and catalytic coated respectively uncoated ceramic monoliths. The regeneration was forced using either an oilburner, an electrical heating or by throttling the exhaust gas. In one case a coating was tested in order to decrease the ignition temperature of soot. For the exhaust emission measurement under instationary conditions a measuring technique was developed with proportional volume sampling. A ceramic trap with regeneration by oilburner fitted into a bus and one with electrical heating installed into a truck showed the best results. These both systems have been proved to be suitable in principle for fitting into vehicles in use. Therefore they will be developed and improved in the future.
