Abstract:Environmental aspects are an essential part of economic development. Improvement of the environmental situation can have a significant impact on the pace and structure of economic development. For environmental component, it is important to analyze the current state and predict greenhouse gas emissions. The development of methodological approaches in this area will allow for more detailed forecasting of the situation. In order to reduce the emission of greenhouse gases, European countries have set targets for … Show more
“…It is worth mentioning that most of the energy consumed for transport purposes comes from petroleum, which leads to the limitation of natural fuel resources. Therefore, changes in the structure of fuel production can be observed, which results in alternatives such as electromobility, hybrid technologies, biohydrocarbons, or biofuels such as methyl esters or bioethanol [29][30][31][32][33]. It is worth mentioning autonomous driving with artificial intelli-gence technologies, which is under scientific research [34], and its impact on both traffic and the environment.…”
The main aim of this article is to dynamically evaluate the sustainable development of transportation as an important economic sector in each member state of the European Union. Furthermore, the authors tried to identify underdeveloped spatial areas and indicate related trends in particular countries. To address this research topic, a multivariate-order statistical measure was implemented. The data sources of the study were Eurostat databases. The rankings of the chosen European Union countries for transport sustainability and its individual components (pillars and orders) were obtained for 2016–2019. This allowed the underdeveloped space regions and their individual pillars in the field of transportation sustainability to be identified in an appropriate manner. Then, the total (general) synthetic measures applicable to the entire period of analysis were constructed. It should be noted that the initial set of diagnostic variables and its classification in certain sequences were implemented. Furthermore, the taxonomic method applied with Weber’s multivariate median was first used to dynamically assess aspects of traffic sustainability. Such synthetic methods allow for analysis of the interaction of different areas of complex transportation systems and allow distortions of the diagnostic variables.

“…Among the traditional sources of energy, oil occupies a special place, the dynamics of production and consumption, which has the most significant influence on the conjuncture of the world energy market and many countries' economies (Eder et al, 2018;Filimonova et al, 2019). Oil consumption, in general, has a positive effect on economic growth since it is one of the main types of fuel in industry and transport (Eder et al, 2019). An increase in natural gas consumption should also have a positive effect on the growth of total income.…”
“…The research octane number (RON) measures highway performance under normal conditions with an inlet temperature of 65.6 o C and revolutions per minute (600 rpm). Motor octane number (MON) indicates performance at high speeds when the intake temperature is high (148.9 o C) and the RPM is high (900rpm) [7]. The automated igniting of the fuel causes the gasoline engine to knock.…”
Gasoline is a petroleum-derived liquid that is most typically used in internal combustion engines, especially those utilizing spark ignition. Gasoline is a hydrocarbon blend that contains sulfur, nitrogen, oxygen, and other metals. Olefins, aromatics, paraffin, and naphthenes are the four main components of gasoline. An octane number is a unit of measurement for the ignition quality or flammability of gasoline.It is frequently referred to as the research octane number (RON), and it is calculated using a ratio of isooctane to n-heptane. The octane number can be decreased by lengthening the hydrocarbon molecule chain and increasing by branching the carbon chain. Another method is to use an octane number increaser for gasoline as an addition. These are classified as oxygenate, ether, antiknock agent, nanoparticles, and aromatic compounds. Numerous studies have been conducted to establish the influence of additives in gasoline on engine performance metrics such as braking power, thermal brake efficiency, volumetric efficiency, fuel consumption efficiency, and their impact on the environment. This review article aims to assess and compare the effects of various gasoline additives on the performance and emission characteristics of ignition engines.
