      • 승용디젤차량의 백연저감 DPF 촉매시스템 개발

        정희찬(Heechan Jeong),최성무(Sungmu Choi),서정민(Jungmin Seo),주기형(Kihyeong Joo) 한국자동차공학회 2015 한국자동차공학회 부문종합 학술대회 Vol.2015 No.5

        White smoke from the diesel vehicles with DPF using high sulfur fuel (> 50 ppm) are not being selling up to now. The emerging markets like BRIC’s are using quite stringent emission regulations like EU4 and EU5. But their fuel qualities are not higher than their emission regulation. Their poor fuel qualities are preventing car makers from using DPF system to reduce particulate matter. To prevent emitting white smoke and meet EU4 and EU5 emission regulation with DPF in these countries that have poor fuel quality, DOC+DPF system that suppresses white smoke was newly developed. Based on this development, DOC+DPF system that meets Chinese emission regulation like KUK 4 and KUK 5 or India emission regulation like BS4 and BS5 were developed and the mechanism of white smoke was also investigated. By applying this white smoke suppression system, diesel vehicle with DPF can be sold in BRIC’s market. Therefore it is expected that this DOC+DPF that suppresses white smoke can contribute to increasing sales of diesel vehicles in BRIC’s market a lot.
