    The Impact of Using Trailers on the Fuel Consumption
    (University of Zilina, 2018) Synák, František; Rievaj, Vladimír; Semanová, Štefánia; Palúch, Ján
    The amount of fuel consumed may also be influenced by driving style, speed as well as by the need for the use of passenger car trailers. This paper deals with the impact of using such trailers on the amount of fuel consumed. Measurement of the impact of the passenger car trailer on fuel consumption was carried out during driving at constant speed and during acceleration. The measurements were performed by driving test on a flat road. The first part of the paper deals with the driving resistances which influence fuel consumption during driving at constant speed and during acceleration on the flat road. The second part describes the vehicle used for measurements and measuring equipment. The conclusion of the paper includes the principles to reduce the impact of passenger car trailers on the amount of fuel consumed.

    The impact of roof box on fuel consumption
    (University of Zilina, 2017) Synák, František; Rievaj, Vladimír
    Passenger vehicles are major petroleum consumers and contributors of greenhouse gas and criteria pollutant emissions in many countries around the world. The amount of fuel consumed affects the environment, status of health of human population as well as financial costs that are associated with vehicle operation. The roof box is one of the often used vehicle attachments. The aim of the paper is to measure the increase of fuel consumption affected by an installed roof box. The impact of roof box on the increase of fuel consumption is measured at the speeds of 50 km.h-1, 90 km.h-1 and 130 km.h-1. The introduction of the paper describes particular harmful constituents of exhaust gases and their effects. Another part of the article includes the methodology of measurement and its results. The last part of the article involves the evaluation of results and recommendations relating to reduction of the increase of fuel consumption affected by roof box.
