TIME TO GO GREEN

The author reports on a Scania environmental seminar where various ways of reducing exhaust emissions were explored. The pollutants formed on the combustion of fossil fuel are listed, subsequent chemical reactions noted and the effects on humans described. Particular attention is paid to diesel engines where particulate matter is a problem. Development of the diesel engine has leaned towards better reliability and fuel consumption. The efficiency of a diesel engine depends on high temperatures and this also favours the formation of nitrogen oxides. Soot can be reduced by higher injection pressures producing smaller fuel droplets allowing for a more complete burn but the timing is difficult to influence. Filters used in the USA are described. Oil companies may be forced to remove the sulphur from diesel fuel as this contributes to a third of particulate gases. Alternative fuels which may be available in the future are considered. Alcohol is the most likely and NOx values would be reduced by 30%. The aldehydes derived from the combustion of alcohol however are an unknown quantity. Meanwhile Scania will be producing diesel engines with NOx emissions 70% lower than they were in 1980.
