Abstract
As a major pollutant source, the diesel engine, which was devised by need of high power plant, has been used for vehicles, vessels, generation of electric power and so on. Therefore, in order to continuously adopt the affirmative sides of diesel engines and solve the environmental problems related to them simultaneously, some units used for diesel engine exhaust aftertreatment (diesel particulate filter, catalyst, diesel oxidation catalyst, and etc.) should be reformed or redesigned. Consequently, if they are equipped, it is expected to drastically reduce the pollutant such as soot and concentration of NOx and SOx which the diesel exhaust gas contains. In view of the system reliability, their operating conditions should be examined in detail before it is applied to the commercial system. In the present study, the effects of temperature increasing patterns on regeneration in the diesel particulate filter, which can filter and regenerate particulate matters, are numerically predicted. Particularly, the characteristics of thermal expansion, which is directly related to the thermal stress of diesel particulate filters, are analyzed.
