Special Issue Information

Dear Colleagues,

At the present time, decarbonization in the transportation and energy sectors is the hardest challenge for science and industry of this sector. Despite mid-century strategies based on electrification of transports and renewable energy production, more than 80% of the world’s energy still comes from fossil fuels. A more sustainable pathway for a clever fuel usage represents a short-term solution to mitigate greenhouse gas (GHG) emissions. The target of this Special Issue is to collect recent research in advanced solutions to reduce the transportation environmental impact by means of efficient combustion systems and alternative fuels. Green fuels from renewable sources or coming from a sustainable management of waste of industrial processes to the end of a circular economy are hot topics.

We invite researchers to submit both original research and review articles that explore this theme. Innovative experimental and numerical works are welcome. Topics of interest for this Special Issue include (but are not limited to):

  • Biofuels;
  • E-fuels;
  • Alternative fuels;
  • Free carbon fuels;
  • Hydrogen fuels
  • Fuel economy;
  • Fuel cells;
  • Bioenergy;
  • Waste oil;
  • Alternative combustion processes;
  • Advanced ignition and combustion systems;
  • Advanced fuel injection systems;
  • Waste heat recovery;
  • Emission regulations;
  • Combustion systems emissions.

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. Sustainability 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 1900 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.

Several countries have set ambitious targets for the transport sector that mandate a gradual increase in advanced biofuel content in the coming years. The current work addresses this transition and indicates two promising gasoline bio-blendstocks: Anisole and isobutanol. The whole value chains of these bio-components were considered, focusing on end-use performance, but also analyzing feedstock and its conversion, well-to wheel (WTW) greenhouse gas (GHG) emissions and costs. Three alternative fuels, namely a ternary blend (15% anisole, 15% isobutanol, 70% fossil gasoline on an energy basis) and two binary blends (15% anisole with fossil gasoline and 30% isobutanol with fossil gasoline), were tested, focusing on their drop-in applicability in spark ignition (SI) engines. The formulated liquid fuels performed well and showed the potential to increase brake thermal efficiency (BTE) by 1.4% on average. Measured unburned hydrocarbons (HC) and carbon monoxide (CO) emissions were increased on average by 12–29% and 17–51%, respectively. However, HC and CO concentrations and exhaust temperatures were at acceptable levels for proper catalyst operation. The studied blends were estimated to bring 11–22% of WTW GHG emission reductions compared to base gasoline. Additionally, the fleet performance and benefits of flexi-fuel vehicles (FFV) were modeled for ternary blends. Full article

The current work addresses this transition and indicates two promising gasoline bio-blendstocks: anisole and isobutanol. The whole value chains of these bio-components were considered, focusing on end-use performance, but also analyzing feedstock and its conversion, well-to wheel (WTW) greenhouse gas (GHG) emissions and costs.

Formulated liquid fuels performed well and showed a potential to increase brake thermal efficiency (BTE) by 1.4% on average. Measured unburned hydrocarbons (HC) and carbon monoxide (CO) emissions were increased, even for alcohol blends, but their concentrations and exhaust temperatures were at acceptable levels for proper catalyst operation. Studied blends were estimated to bring 11-22% of WTW GHG emission reductions compared to base gasoline. Additionally, the fleet performance and benefits of flexi-fuel vehicles (FFV) were modeled for ternary blends.
