Data required from extensive studies concerning the driving behavior in European cities were analyzed and compared to driving cycles used in exhaust emission testing. The US 72 cycle is found to be a good approximation, nevertheless it should be modified. Especially its total duration and its feasibility to weight the engine warm up phase must be optimized. An improved driving cycle based on the US 72 cycle was developed which lasts 445 seconds. This cycle should be repeated once - using separate CVS sampling bags - so that the influence of the warm-up phase can be taken into account. (DePo)
