Roadway-tunnel experiment for the determination of the characteristic emission of the Hungarian car-fleet

Abstract

Due to the special composition of the aged Hungarian car fleet, the characteristic emission considerably differs from that in the Western European countries which should be considered in the European scale atmospheric chemistry models, as proved by the measurements in 1990. The ratio of the obsolete Eastern European cars, including those with two-stroke engines, has decreased during the past 7 yr. Mandatory annual emission test has been introduced and unleaded gasoline is widely used. The portion of the cars equipped with three-way catalyst has been slowly increasing. However, the average age of the car fleet is still increasing, exceeding 11 yr in 1997. A roadway-tunnel experiment was conducted in 1997 in Budapest, Hungary, to investigate the changes resulted in the characteristic emission. Results were presented and compared with the previous, similar measurements performed in 1990.
