Engine Emissions and Air Quality

Dear Colleagues,

Modern economy largely relies on the transport of goods and people, which is largely powered by internal combustion engines. As a result, road transport is a significant sector for energy consumption and greenhouse gas emissions, and is increasing due to economic and population growth. The International Energy Agency reported that the energy use in the transport sector significantly increased from 23% of total final consumption in 1971 to 29% in 2015. Meanwhile, exposure to poor air quality continues to be a critical issue concerning the public health worldwide. The World Health Organisation estimated that ambient air pollution causes 4.2 million premature deaths per year globally. Motor vehicles, especially diesel vehicles, are the main source of air pollution in our cities. Therefore, great efforts have been undertaken to reduce energy consumption and pollutant emissions from motor vehicles, such as more stringent emission standards for new vehicles, inspection and maintenance (I/M) programs for in-use vehicles, new engine and vehicle technologies (e.g. engine downsizing, low temperature combustion, and hybrid and electric vehicles), better fuel quality and renewable fuels.

This Special Issue aims to collect original research and review papers on vehicle-related energy and environmental problems. All experimental and numerical studies that support fuel savings, emissions reduction, and air quality protection are welcome.

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. Atmosphere is an international peer-reviewed open access monthly 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 2400 CHF (Swiss Francs).
