The Experimental Study on the mechanism occurred of white smoke of Diesel Particulate Filter were investigated in DI injection TCI diesel engine. The diesel particulate filter mounted the diesel engine in this study were performed to leave the 10 hours in sub-zero temperatures to same of field conditions. As the result, it is shown that the white smoke was occurred around 50℃before the filter temperature and raised some liquid from the system about 120~130℃. Most of the ingredients in liquids have been formed by water.

Today diesel engines are used extensively in the automotive, because they have excellent fuel economy and performance. But emissions from diesel engines are a significant air-quality issue by high emission of the NOx and PM. Many methods of aftertreatment have been developed since the advent of emission standards for diesel engines. The diesel aftertreatment system can be classifie into various categories by its target emission and reduction mechanism. The control methods and operating conditions are very important consideration for an each aftertreatment system. It is necessary to test with engine dynamometer precisely, since the characteristics of diesel emission are important parameters for the development of aftertreatment system. Although engine dynamometer test is necessary, it is not cost-effective. To reduce the prime cost, it is needed to build more cost-effective test equipments, In this work, the simple evaluation system was examined as a means of testing cost-effective using a real diesel engine and water-brake system.
