Special Issue Information

Dear Colleagues,

Because the current electric vehicles (EV) still have problems such as insufficient charging stations, long charging time, high initial cost, limited driving range and battery pack, traditional internal combustion engines (ICE) still play an important role in the automobile industry, transportation industry, agriculture, construction industry and power generation industry. Among this, transportation posits as a major consumer with the ICE at its heart, driving a wide range of terrestrial, aviation, and marine prime movers. However, ICE, including diesel engines and gasoline engines, use fossil fuels as the main fuel. The large consumption of fossil fuels has led to a series of problems such as an energy crisis, global warming, abnormal climate change and haze-fog pollution. In order to meet the increasingly stringent emission and fuel consumption regulations of ICE, many researchers have investigated various advanced technologies (direct injection: DI, multiple injection strategies: MIS, variable valve timing: VVT, variable compression ratio: VCR) blended fuels (binary, ternary and quaternary) combustion, new combustion technologies (low temperature combustion: LTC, homogeneous charge compression ignition: HCCI), etc., in recent decades. In addition, many countries have begun to develop ICE with a thermal efficiency over 50%. Once the thermal efficiency of ICE exceeds 50%, the exhaust emissions and heat loss of the engine can be well controlled, which is very beneficial to improve the competitiveness of ICE against EV. Therefore, finding new ways to improve the combustion efficiency and reduce exhaust emissions from ICE have become widespread concerns in the global hot topic. This Special Issue aims to discover and promote the latest development technologies, innovations and practical solutions for the sustainable development of ICE.

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. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Abstract
In this study, pure diesel fuel (E0), 5% bioethanol blended with 95% diesel fuel (E5), 10% bioethanol blended with 90% diesel fuel (E10) and 15% bioethanol blended with 85% diesel fuel (E15) were tested on a diesel engine. The 40, 60 and 80 [...] Read more.
In this study, pure diesel fuel (E0), 5% bioethanol blended with 95% diesel fuel (E5), 10% bioethanol blended with 90% diesel fuel (E10) and 15% bioethanol blended with 85% diesel fuel (E15) were tested on a diesel engine. The 40, 60 and 80 Nm were the main experimental variables, while the engine speed was kept constant at 1500 rpm. The main results show that the addition of ethanol slightly reduced the maximum combustion pressure and delayed the combustion start, but increased the heat release rate (HRR) to varying degrees. Although the addition of ethanol was not very helpful for reducing hydrocarbon (HC), it could reduce carbon monoxide (CO) under appropriate load conditions (60 Nm and 80 Nm). Additionally, nitrogen oxides (NOx) and smoke emissions were reduced with the addition of ethanol under all test conditions. Full article
