대형디젤기관에서의 연속재생방식 DPF와 Cooled EGR 성능

The world is faced against the serious problems related to the increasing air pollutions. This research focused on the principle and the development of continuous regeneration DPF and cooled EGR technology which were the after-treatment technologies due to its superior comparability ad possible applicability. The test was done on an 8000cc heavy-duty turbo diesel engine on which continuous regeneration DPF was installed in order to investigate regeneration characteristics of DPF and cooled EGR and engine performance under several conditions of standard diesel or 50ppm ultra low sulfur diesel. Besides exhaust emissions, CO, HC and PM were tested under D-13 mode.
