Abstract

Comparative studies exhaust emissions of the Euro VI buses with diesel engine and spark-ignition engine CNG fuelled in real traffic conditions

Highlights

Air pollution coupled with more and more restrictive requirements concerning the emission of hazardous exhaust gases cause that bus fleets in towns and in non-urban traffic are changing considerably
Correlations were developed characterising the impact of dynamic properties of public transport buses on the emission of harmful compounds
The tests in real road traffic conditions resulted in the following conclusions:

Summary

Introduction

Air pollution coupled with more and more restrictive requirements concerning the emission of hazardous exhaust gases cause that bus fleets in towns and in non-urban traffic are changing considerably. In October 2016 year once again an alert was announced that admissible PM10 levels exceeded. According to public alerts admissible levels for air quality as regards benzo(a)pyrene were most likely exceeded in the entire Mazowieckie region, and in some towns and communities for PM10 and PM2.5 and nitrogen dioxide. One of the possibilities as regards vehicles is to replace traditional city fleets with vehicles powered by alternative systems [1]. Another method of reducing emission of hazardous exhaust gases to atmosphere comprises actions aimed at limiting traffic of passenger cars by opting for public transport, e.g. by intensifying actions promoting and improving the public transportation infrastructure [2]
