The analysis of the emission level from a heavy-duty truck in city traffic

Abstract

The paper presents the analysis of the emission level from a heavy-duty truck of the GVW of 12 000 kg. The exhaust emission tests were performed under actual traffic conditions in the area of Poznań. For the tests a portable exhaust emission analyzers SEMTECH DS and AVL Micro Soot Sensor were used. Based on the obtained values of the emission of CO, NOx and PM the emission indexes were determined that provided information on the excess or non-excess of the unit values of the measured components specified in the EEV standard. The vehicle gas mileage was also determined through the carbon balance method.
