AIR POLLUTION BY VEHICLES IN TRAFFIC

LUFTFOERORENINGAR FRAAN FORDON I TRAFIK

From 1991 onwards, the Swedish annual vehicle test will include more stringent exhaust tests for cars of 1989 and later models. The national environment protection board will draw up regulations for this purpose. The emphasis will be laid on a method which pinpoints lack of maintenance in vehicles in traffic. The control system must be capable of detecting high discharges of co, hydrocarbons and no-x. In view of environmental protection and prevention of acidification, special attention is paid to no-x and hydrocarbons. No-x can be measured meaningfully only when the engine is under load. It is considered that the German uba/tuv method is most appropriate for use in Sweden since this is fully developed. It will be introduced gradually in step with the increase in cars with catalytic converters. Until the system has been fully introduced, testing stations where equipment is not available will apply simpler exhaust tests combined with component control on the Swiss model. An experimental programme will be introduced at the testing stations to find if method works in practice. Consideration has been given to a component certification system according to the US model, but for practical and cost reasons its application is not proposed at present.
