Diesel fuel emissions performance with oxidation catalyst equipped diesel passenger vehicles – Part I

Report no. 94/55: This study confirms the very effective control of diesel exhaust particulate, carbon monoxide and hydrocarbon emissions with oxidation catalyst technology. In addition, the investigation documents the ability of an exhaust oxidation catalyst to effectively reduce the variation in emission levels with fuels meeting the EN 590 specifications.

However, a balanced design of catalyst, engine and vehicle seems to be important if optimum performance is to be achieved.
