| The measurement of exhaust emissions is an important element of the vehicle type-approval. The tests in this area are carried out mainly under laboratory conditions, and the obligatory road tests in force since 2017 supplement them. One of the most important requirements in relation to the laboratory tests is the best possible representation of real traffic conditions, as well as ensuring the reliability of the results obtained. Laboratory measurement cycles carried out nowadays assume an unchangeable way of recreating the trip under specific measurement conditions. This is conducive to misuse and, in many cases, obtaining the results that do not reflect the actual exhaust emission. Therefore, it is necessary to develop an alternative test method that would ensure a better representation of the road traffic conditions and allow the test to be individualized according to the type of vehicle or the professional group that uses it. This is possible owing to the proposed, differentiated speed profile during the exhaust emission tests under the laboratory conditions, with simultaneous reliable reconstruction of the road traffic conditions during bench measurements. The article describes a new measurement method that meets these requirements, based on a random selection of measurement sections. It was also validated by comparing the obtained results with the actual exhaust emission recorded during road tests. It has been proven that the method developed corresponds to the random nature of road traffic conditions, while maintaining the similarity of the emissions of toxic exhaust components, and therefore constitutes an effective and expected alternative to the currently used type-approval procedures. |
