Abstract

In Hong Kong, diesel emission standard for light duty vehicles has been tightened with respect to their influence to the air quality. In the present study, on-road measurement tests were performed to evaluate the effectiveness of Diesel Oxidation Catalyst (DOC) on a 5.5 tonnes light duty vehicle (Euro I diesel engine) under Hong Kong driving conditions. The concentration of gaseous emissions, particle numbers and size distributions were determined by a series of regulated gas analyzer instruments and the Aerodynamic Particle Sizer (APS), The results show that gaseous emissions and exhaust particles are reduced significantly due to the use of DOC. It is also found that the catalyst is unable to function efficiently when the vehicle is cold start. With the application of the DOC, reduction in smoke level can reach a maximum of up to 37% when the vehicle is travelling uphill.
