Research and Development in Single-Cylinder Engines

Dear Colleagues,

The transport sector plays a major role in the development of modern societies, covering fundamental requirements such as people mobility and goods transportation. As a result, the vehicle fleet around the world has increased exponentially over the last decades. Moreover, it is expected that this trend will continue during the next decades due to the development of the emerging countries, where transport energy demand is growing faster. Among the different powertrain sources, internal combustion engines (ICEs) are the most widely used technology nowadays, with a greater than 99.9% share of the total vehicle fleet. As the energy system is decarbonized and battery technology improves, electrification will also take part of the transport scenario at different levels, from hybrid to fully electric solutions. However, it is expected that ICEs will continue to power transport, particularly commercial transport, to a large extent for decades to come. Thus, further research is required to obtain environmentally friendlier ICE-powertrains, improving their performance and reducing their emissions down to the levels imposed by the restrictive emissions regulations.

This Special Issue encourages both academic and industrial researchers working in this field to share their latest developments made using single-cylinder engines (SCE) as a research platform. Topics of interest include (but are not limited to) the following:

• Comprehension combustion studies in spark and compression ignition engines;
• Visualization studies in optical SCE;
• The development of new combustion approaches (fuels, combustion strategies, etc.);
• New hardware development;
• The design and development of SCE.

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 submissions that pass pre-check are 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 2600 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.
