Abstract

The subject of this article is a comparative analysis of exhaust emissions for: HC (hydrocarbons), CO (carbon monoxide), CO2 (car-bon dioxide), NOx (nitrogen oxides) from a passenger vehicle and a motorcycle in laboratory conditions on a dynamometer station. The first vehicle category was represented by a compression-ignition engine with a displacement volume of 1.3 dm3 and a power of 66 kW. The exhaust aftertreatment system included a catalytic converter and a particulate filter. The second category was a motorcycle, equipped with an engine with a displacement of 0.7 dm3 and a maximum power of 55 kW. The two-wheeled vehicle was equipped with a three-way catalytic converter. Speeds were modeled on the European type approval test – NEDC (New European Driving Cycle). In order to conduct a comparative analysis of exhaust emissions and fuel consumption from vehicles of different categories, the obtained results were presented in the form of emissions converted into passenger-kilometers (g/pkm). The research used modern equipment belonging to the PEMS (Portable Emissions Measurement Systems) group of devices. The analyzes carried out enable the decision mak-ing on which vehicles have a greater environmental impact due to their exhaust emissions, taking into account the distance and the number of passengers carried.

Highlights

Globalization, leading towards the integration and interdependence of countries worldwide, in the cultural and in the economic aspect, results in a smoother exchange of goods and their mass consumption
For the motorcycle the emission values of CO and NOx were recorded to be 47 and 92% lower respectively relative to the passenger car. This outcome was the result of the high exhaust gas aftertreatment system efficiency of the motorcycle, which existed in the form of a three-way catalytic converter
The emission values obtained for various categories of vehicles were used for comparison (Fig. 8)

Summary

Introduction

Globalization, leading towards the integration and interdependence of countries worldwide, in the cultural and in the economic aspect, results in a smoother exchange of goods and their mass consumption The scientific work describing the average number of passengers per car in the Białystok agglomeration on various days of the week was on average 1.54 [2] In the light of these problems, this publication is related to considerations regarding the emissivity of various types of vehicles (motorcycles and mopeds and passenger cars) in terms of their transport capacity. Comparative analysis of exhaust emissions from passenger cars and motorcycles thors have compared the emissions of toxic compounds and the fuel consumption of a motorcycle and passenger car per one passenger kilometer
