Analysis of pollutant emissions of a lorry for different EURO standards and operating conditions

Abstract

Environmental pollution is becoming an increasingly important problem that needs to be solved, and road vehicles contribution in that pollution is significant. In that sense, in this paper, a brief overview of models used to determine pollutant emissions is given, and then the environmental pollution of an actual lorry with a maximum permissible mass of up to 7.5 t is specifically considered. While determining pollutant emissions different Euro standards, average vehicle speeds, payload utilizations and longitudinal road slopes were taken into account. Emissions of carbon monoxide (CO), nitrogen oxides (NOx) and particulate matter (PM) were observed in detail in this paper.
