This research focused on the principle and the development of continuous regeneration DPF technology which was the best particulate matters removing technology of current existing technologies owing to its superior comparability and possible applicability. In addition, there were some discussions about the affecting engine parameters such as engine driving conditions and the amounts, velocity, temperature, pressure of exhaust emissions as well as sulfur contents and lubricants which were prerequisites to prevent poisoning effect on catalysts. The test was made on an 8000cc heavy-duty turbo diesel engine on which continuous regeneration DPF was in order to investigate regeneration characteristics of DPF and me performance under the condition of standard or 50ppm low sulphur diesel. Exhaust emissions, CO, HC, NOx PM were measured and compared under D-13 modes.
