PASSENGER CAR EMISSIONS IN THE SPEED RANGE 80-120 KM - H. TRAFFIC MEASUREMENTS ON A FLEET OF CARS IN THE PFAENDER ROAD TUNNEL
A fleet of 70 private cars, chosen to be representative as to cylinder capacity, state of maintenance and age distribution, were measured under traffic conditions for NO-x, SO-2 and hydrocarbon- emissions. The experimental setup: In the night from 2nd to 3rd November 1984 the Pfaender road tunnel, which has been closed for traffic, was driven through at varying speeds, and the entire emissions were measured in both waste air shafts under careful setting of the ventilation conditions. The entire volume of harmful substances released was calculated from concentration and air throughput volume. This experiment fills a gap in the insight into and the methodological approach to the solving of similar problems, as published information was hitherto most by gained from calculations supported by rolling bench tests, with the authors regretting that "tests on the road seemed to be a technical impossibility, for the time being".
