The results of measurements of exhaust emissions in real road traffic differ significantly from the results of stationary homologation tests. One of the solutions, helpful in determining the actual emission, is the creation of stationary exhaust emission tests simulating the use of the vehicle on the road. The article presents the method of reconstructing the synthetic driving test obtained on the basis of road tests and presents the obtained profile of the speed course. The authors discussed the reasonableness of selecting the emission component determining the correctness of the representativity of the stationary test obtained, which determines the amount of work done by the engine.
