Abstract
Exhaust emission measurements on the chassis dynamometer are one of the most important and most complex tests which are performed on vehicles powered by combustion engines. The sample and dilution system (CVS - Constant Volume Sampling) belongs to the most important parts of the exhaust emission laboratory, and has a large impact on the accuracy of the results obtained. In this paper, the influence of the dilution factor (i.e. parameter changed by means of the CVS system, depending on the emission level and engine displacement of the test vehicle) on the uncertainty of the exhaust gas emission results is analysed.
