This article discusses three strategies to reduce the exhaust emissions of diesel engines. The modification of fuel to reduce the carbonaceous fraction and sulphur content could in addition reduce damage to exhausts and after-treatment devices but is expensive. An improvement to the combustion process would reduce pollutants but increase fuel consumption. Parameters to be observed in optimising this process are listed. Other solutions currently being studied are after-treatment techniques. Problems in the development of particulate traps and oxidation catalytic converters are described. The authors suggest that in the long term diesel engines will allow a 25-35% improvement in fuel economy and a reduction in carbon dioxide emissions. Suggestions are listed for more short term modifications. For the covering abstract see IRRD 864909.
