Evaluation of Fuel Consumption in Road Freight Transport

Abstract

This paper deals with the importance of fuel economy in road freight transport. It provides the calculation of financial savings for fuel savings of 0.5 l per 100 km. In the subsequent part, some factors that influence the fuel consumption are specified, e.g. aerodynamic resistance, rolling resistance, and tyre inflation pressure. The effect of tyre inflation pressure on fuel economy has been tested on four selected towing vehicles. Based on the results obtained, it can be stated that tyre pressure has a great impact on fuel consumption. A one-bar pressure reduction of tyres can increase the fuel consumption by 0.5 l per 100 km.

Compensation of CO2 Emissions from Petrol Stations with Photovoltaic Parks: Cost-Benefit and Risk Analysis

“…According to the roadmap, the emissions should be cut to 40% below the 1990 levels by 2030 and to 80% below the 1990 levels by 2050. Globally, the road transport sector is one of the main sources of carbon dioxide emissions and pollution (Lenďák et al, 2013;Szabó et al, 2013); therefore, the reduction of emissions from this sector is one of the key objectives in order to meet the Kyoto Protocol and create a sustainable transport system (Fontaras and Samaras, 2007). In the European Commission's roadmap, the share of the transport sector is set to be reduced by 60% by 2050 from the 1990 levels.…”
