STANDARDISATION OF A LIMIT EMISSION VALUE FOR BENZO(A)PYRENE IN EXHAUST GASES OF PETROL ENGINES

STANDARDISIERUNG EINES EMISSIONSGRENZWERTES FUER BENZO(A)PYREN AUS ABGASEN VON PKW-OTTOMOTOREN

THE REASONING BEHIND AND CONTENTS OF THE DRAFT STANDARD TGL 33353 "MOTOR VEHICLES, MAXIMUM PERMISSIBLE VALUES OF BENZO(A)PYRENE EMISSION DURING EXHAUST TESTS ON A DRIVING CYCLE" ARE REPRODUCED HERE. THE GDR AUTHORITIES WISH TO SET A STANDARD FOR THE EMISSION LEVELS FOR INTERNAL COMBUSTION ENGINES. IN THE GDR CENTRE FOR TESTING EXHAUST EMISSION, TESTS WERE CARRIED OUT TO ESTABLISH THE BENZO(A)PYRENE EMISSION LEVEL FOR VEHICLES WITH PETROL ENGINES, USING THE EUROPEAN DRIVING CYCLE EXHAUST TEST, WHICH IS OBLIGATORY IN THE GDR. MEASUREMENTS OF THE BAP EMISSION BY THE EFA TEST OF 100 VEHICLES AUTHORISED IN WEST GERMANY SINCE 1.10.71 GAVE A MEAN EMISSION VALUE OF 41.6 UG/TEST, WHEREBY LARGE VARIATIONS COULD BE IDENTIFIED BETWEEN DIFFERENT VEHICLES. IN THE GDR DRAFT STANDARD, 120 UG/TEST IS INCLUDED AS THE ALLOWABLE VALUE. APPROXIMATELY 85 PER CENT OF ALL CARS TESTED SATISFY THIS LIMIT, AS CAN BE SEEN FROM A DIAGRAM.
