LEGISLATION ON EXHAUST GAS EMISSION AND THE EFFECTS OF THIS ON DIESEL AND PETROL ENGINES

ABGASGESETZGEBUNG UND DEREN EINFLUSS AUF DIESEL- UND OTTOMOTOREN

The proportion of damaging exhaust gases from the complete emission from petrol engines is approximately 1% and consists almost entirely of carbon monoxide (CO), carburetted hydrogen (ch) and nitric acid (NO(x)) Traffic produces only a small part of the damaging gases which result from human activities and in nature (approximately 2% of damaging material emitted). The amount of damaging material from motor vehicles permitted in different countries is legally controlled. In the USA carbon monoxide emission permitted was reduced to less than 3% of that permitted in 1966. Also the permitted amounts of carburetted hydrogen and nitric acid are greatly reduced compared with previous values. The damaging emission from a motor vehicle is affected by three factors - the mixture, composition, by measures undertaken in the engine design and by after treatment of the gas. Diesel engines are of particular interest when considering exhaust gas purification. They behave more favourably than petrol engines for all three components of the exhaust gas. The following measures can be undertaken within the engine: delayed start of injection, small blind hole volume, avoidance of late injection, higher injection pressure, directing the exhaust gases back and boosted air cooling. One area of difficulty when running development projects is the avoidance of measures for exhaust gas purification which worsen the degree of efficiency of the engine and increase fuel consumption. A considerable proportion of the total distance driven by our vehicles is on short journeys at low average speeds. This is an area where the diesel engine is particularly superior to the petrol engine. (TRRL)
