![]() The results of the analysis show that, in the case of a small number of measurements, the results repeatability analysis is necessary for a proper interpretation of the pollutant emission results on the basis of the mean value. The aim of the research is to draw attention to the accuracy of the pollutant emission research results in driving cycles, and the comparison of pollutant emission results and their repeatability obtained in successive NEDC cycles under cold and hot start conditions. The emission of CO, CH 4, CO 2, NO X, THC, and NMHC was subjected to the analysis. The research was conducted in a climate chamber, enabling the temperature conditions to be determined from − 20 to + 30 ☌. This article presents the assessment of repeatability of the passenger car engine exhaust pollutants emission research results obtained in the conditions of a chassis dynamometer. ![]() Measurement of car engines exhaust pollutants emissions is very important because of their harmful effects on the environment. ![]()
