Abstract

The article presents the results of measurements of exhaust emissions of commercial vehicle in real traffic conditions. The aim of this study was to initial verification how the driving style affects on the exhaust emissions from vehicle engine and fuel consumption. The determinants were the measurements of the concentration of CO2 and others harmful substances emitted to the atmosphere from the power unit of the tested vehicle. In the measurements a portable exhaust emission analyzer was used (PEMS type).

Highlights

  • In the automotive circles has appeared and has been functioning the idea of eco-driving [13]

  • In 2007 12 % of the surveyed declared their belief in eco-driving reducing fuel consumption [12] while in November 2012 it was already an opinion of 26 % of the surveyed. This 14-percent increase proves that the eco-driving awareness is still an open issue

  • It should be added that the same principles of eco-driving are quite vague, which may cause difficulties in their precise application

Summary

Introduction

In the automotive circles has appeared and has been functioning the idea of eco-driving [13]. The principles of eco-driving first came into being in Switzerland and Finland in the second half of the 90’s in the 20th century. The popularity of this driving style among the drivers is constantly increasing. In 2007 12 % of the surveyed declared their belief in eco-driving reducing fuel consumption [12] while in November 2012 it was already an opinion of 26 % of the surveyed. This 14-percent increase proves that the eco-driving awareness is still an open issue. It should be added that the same principles of eco-driving are quite vague, which may cause difficulties in their precise application
