A one-day tunnel experiment was performed in downtown Budapest to measure the average non-methane hydrocarbon composition of the exhaust of the Hungarian car fleet. It was found that the exhaust is richer in gasoline-originated alkanes in Hungary than in the United States of America for which data for comparison were available. This phenomenon may be caused by the extended usage of cars equipped with two-stroke engines and by the lower efficiency of the engines in general but the effect of the different composition of the gasoline cannot be excluded either.
