HOW DO DIESEL AND GASOLINE ENGINE EMISSIONS COMPARE?

Southwest Research Institute (SwRI) has undertaken a head-to-head comparison of diesel- and gasoline-fueled passenger cars. The results corroborate recognized tradeoffs of dieselization: some 30-60% better fuel economy, moderate losses in acceleration, a bit more noise, and levels of regulated emissions comparable to those of converter-equipped gasoline cars. Unregulated emissions, however, may require new techniques for adequate quantification and control. In particular, the study pinpoints particulates, polynuclear aromatics, smoke, and odor as matters of potential concern with an expanding diesel passenger car fleet.
