The effects of sulfur content of diesel fuel on oxidation catalyst were investigated using from 0.2 weight % to 0.05 weight % sulfur content fuel on engine dynamometer and the characteristics of the emission reduction were tested using the prepared catalyst at various operating conditions such as T-6 mode with and without Pt/V and Pt catalysts in the exhaust system.
In addition. the prepared catalytic converter was installed to a heavy-duty diesel engine and light-duty diesel vehicle. Then the emission reduction performance of Pt/V and Pt catalyst was also compared with each regulation test mode such as D-13 CVS-75 mode
The emission reduction performance of Pt catalyst with respect to CO, HC, SOF and aldehyde was found to be a little bit higher than that of Pt/V catalyst, but Pt catalyst showed the innate disadvantage of causing the increase of PM due to the sulfate formation via high SO₂ conversion at high exhaust temperature especially above 500℃ in heavy-duty diesel engine.
In the D-13 mode, PM reduction efficiency of Pt catalyst equipped heavy-duty diesel engine is lower than that of Pt/V catalyst caused by increasing sulfate in the high exhaust temperature but in the CVS-75 mode. Pt catalyst equipped light-duty vehicle showed higher PM reduction efficiency than that of Pt/V catalyst.
