  • The application of the Monte Carlo method to the results of empirical research in the RDE test turned out to be an effective way to determine the characteristics of pollutant emissions in the conditions of real car use.
  • The scope of the article was to study the properties of a light duty vehicle combustion engine in conditions simulating its real operation.
The article contains the research results and analysis of the processes that take place as part of a gasoline engine light duty vehi-cle Real Driving Emissions test. Dimensionless characteristics of exhaust emission and fuel mass consumption in the RDE test were also determined: emission intensity, particle number emission intensity, fuel mass consumption intensity. An algorithm for determining the characteristics specific distance pollutant emission, specific distance particle number and specific distance fuel mass consumption in the vehicle speed domain in the RDE test was presented using the Monte Carlo method. The determined characteristics were approximated by polynomial functions in the form of sets of points. These relationships were characterized by a large dispersion of values, which was primarily due to the fact that the random values of the averaging limits contain very different engine operating conditions.
