Welcome to the website of the journal Paliva ("Fuels"). The journal is Open Access, with articles published under CC BY 4.0 license. The journal is issued online only.
Paliva journal is open not only to researchers but also for technicians and other professionals working in plants, refineries, power stations, gasworks and companies processing, handling or trading both fossil and alternative fuels. The aim of the journal is to share information between professional research organizations and users of research results.
Since 2010 the journal Paliva (Fuels) is included in the list of recognized peer-reviewed journals, issued by the Research, Development and Innovation Council of the government of the Czech Republic. Amongst other requirements that must be met to be a member of the group of journals, all papers published in the journal undergo a review process by two independent reviewers. We sincerely hope you become regular readers of the journal and perhaps contributors in its future issues.
Paliva (Fuels) included in Scopus database
In 2019, when Paliva celebrated its 10th anniversary, the journal was succesfully evaluated and included in Scopus. Paliva is the only periodical in its research field published in the Czech Republic indexed by Scopus database. Since then, we expect further increase of the quality of published papers and greater proportion of papers written in English. It is also an oncoming opportunity for new authors from both industry and academic sphere.

Emissions evaluation of a diesel engine fueled by a water-diesel emulsion
Water–diesel (W/D) emulsions have emerged as a promising for reducing harmful exhaust emissions while maintaining diesel engine performance, particularly emissions of nitrogen oxides (NOx) and smoke opacity (SO). This study investigated the effects of two (W/D) emulsion ratios containing 7% and 17% water by volume on the exhaust emissions of a water-cooled, 4-cylinder, direct-injection diesel engine operating at a constant speed of 1600 rpm under various load conditions. The experimental results demonstrated that the 7% (W/D) emulsion reduced NOx and SO emissions by 27% and 82%, respectively, compared with neat diesel fuel. The 17% (W/D) emulsion achieved greater reductions, lowering NOx and SO emissions by 38% and 89%, respectively. Nevertheless, both emulsions increased emissions of carbon monoxide (CO), carbon dioxide (CO₂), and unburned hydrocarbons (HC). For the 7% emulsion, CO, CO₂, and HC emissions increased by 20%, 8%, and 30%, respectively, whereas the corresponding increases for the 17% emulsion were 33%, 24%, and 50%. Overall, although the 17% (W/D) emulsion provided superior reductions in NOx and SO emissions, the 7% W/D emulsion offered a more favorable compromise between the reduction of regulated pollutants and the increase in other exhaust emissions under the investigated operating conditions.
