Special Issue Information

Dear Colleagues,

Undoubtedly, road mobility is the engine of the economic development and is one of the fundamental aspects of the human society, because it allows everyone the freedom of movement. However, road mobility, which is a significantly growing sector worldwide, is currently one of the main sources of the greenhouse gas emissions (specifically, CO2 emissions) and city pollution. More exactly, the internal combustion engine as the most used technology for ensuring that road mobility is held accountable for the intensification of the above-presented problems. Consequently, facing ever-stricter regulations and increasing competition from the electric alternative, there is a pressure without precedent to make the internal combustion engine cleaner and more efficient, while still keeping its well-known value-for-money feature. In other words, the ongoing optimization of the internal combustion engine is still essential for the future of road mobility, which objectively speaking, cannot be suddenly shifted to fully electric vehicles.

This is why the main purpose of this Special Issue is to gather the latest scientific results on the following generic topics: (1) “how-to-burn” a fuel in order to achieve highly efficient and clean internal combustion engine suitable for the sustainable road mobility and (2) “what-to-burn” inside an engine, i.e., sustainable fuels produced from renewable energy sources.

Thus, papers are invited on (but not necessarily limited to) any of the generic topics below. Any other paper presented on a topic not explictly quoted below, but having scientific interest for this Special Issue will be taken into consideration.

Finally, as editors coming from academia, we also hope that with these papers, we will succeed in clearly and impartially telling all our students and young engineers why a research career in internal combustion engines is still worthwhile.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
