Porovnání ekonomických a ekologických aspektů pohonů LPG a CNG u osobních motorových vozidel a autobusů MHD

Abstract

Traffic is the important source of air pollution and greenhouse gases, while the emission of pollution from the traffic is still increasing. The diploma thesis compares the economical and environmental aspects of LPG engines, used in private cars and vans, and CNG engines, used in buses and trucks. In the introductory part of the thesis we describe the history of using gas in traffic as an alternative fuel, the characteristics of LPG and CNG gases, as well as the economical and environmental advantages and disadvantages of using gases in traffic. In the final part of the thesis we compare the prospects of using the cars powered by LPG and CNG gases.
