초록
In order to reduce the smoke emission from the in-service city bus, this study was evaluated the particulate reduction efficiency and regeneration ability of the catalitic trap oxidizer (CTO) on the city bus (D0846HM engine) equipped with it. Before the on-road CTO test, the laboratory test of CTO on engine test-bench was performed. Reduction efficiencies of smokes and particulates were 54 and 45%, and those of gaseous pollutants such as carbon monoxide (CO) and hydrocarbons (HC) were 90 and 60%. In order to evaluate the regeneration ability of the CTO by the catalytic oxidation of trapped particulate, field test was performed on the in-service road. The regeneration temperature was 350$^\circ$ which was same with the exhaust temperature of city bus.
