AMOUNTS, CLEANING, MEASUREMENT AND LIMITS OF EXHAUST GAS EMISSIONS FROM PETROL CARS

The present level of exhaust gas emissions, available means for their reduction, current measuring techniques, the comparability of measuring results, and trends of development in the field of regulations and technology in Europe are reviewed. Catalytic cleaning is today the most effective method of purification. A so-called three-way catalyst, where both oxidation and reduction reactions take place represents the latest technology. This catalyst with auxiliary equipment is relatively expensive and increases fuel consumption by 10-15%. The use of lead-free petrol makes the use of catalytic exhaust gas purification possible and reduces the amount of nitric compounds in the exhaust gases. According to present knowledge, lead-free petrol will be brought into use in the EEC countries in 1989.
