Automotive Engines Emissions and Control

Dear Colleagues,

The present Special Issue of Energies aims to gather innovative research and highlight recent advances on the very timely and sensitive subject of exhaust emissions from internal combustion engines. It is a well established fact that exhaust emissions from engines contribute significantly to environmental pollution and greenhouse gases on a global scale. As a result, during the last few decades, on the one hand, emission limits have become increasingly stringent, and, on the other hand, emission production mechanisms and control measures, either internal or in the form of after-treatment devices, have been in the focal point of research. Topics of interest for the Special Issue include (but are not limited to):

• Production mechanisms and pollutants formation in spark ignition engines;
• Production mechanisms and pollutants formation in diesel engines;
• Recent advances in emission legislation;
• Exhaust after-treatment systems: three-way catalysts, oxidation catalysts, diesel and gasoline particulate filters, selective catalytic reduction, NO_x adsorbers;
• Internal measures for emissions control (exhaust gas recirculation, water injection, etc);
• Driving cycle effects on pollutants emissions;
• Combustion noise from diesel engines;
• Alternative fuels and biofuels effects on pollutants emissions (ethanol, butanol, biodiesel, ether, Fischer Tropsch, etc.);
• Recent advances in exhaust emissions experimentation;
• Influence of alternative combustion systems, such as HCCI, PCCI and RCCI, on pollutants formation.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized 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.
