Special Issue Information

Dear Colleagues,

We are inviting you to submit your original research to the Special Issue of the journal Applied Sciences, entitled ‘Novel Advances of Combustion and Its Emissions’.

Despite rapid changes within the industry, the process of combustion still remains one of the fundamental methods for the production of electricity and heat. Before the so-called green transformation can be implemented worldwide, it is extremely important to continue our efforts in providing technological solutions for the reduction of pollutant emissions from various industrial processes. Accordingly, the current Special Issue of Applied Sciences is devoted to various modern technologies that are associated with the combustion and thermal treatment of various fuels, as well as the reduction of emissions of unwanted byproducts, ultimately improving the current knowledge and implementation of more environmentally-friendly techniques for both the processing and emission control of fuel. Papers dealing with experimental, conceptual, and modeling works are welcome. Publications focused on the combustion of renewable and ‘bridge’ fuels, such as biomass, waste, and e-fuels, are of particular interests. However, other works dealing with efficient and low emission processes for ‘traditional’ energy carriers and fuels are welcomed also. In this Special Issue, we encourage you to publish papers focusing on the reduction of gaseous and solid pollutants, including data from desulfurization and denitrification plants, as well as other installations where the removal of unwanted byproducts occurs. Publications where decarbonization technologies and new ideas for the CCS and CCU are presented and discussed are also within the scope of this Special Issue.

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. Applied Sciences 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 2400 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.

This research aimed to analyze the possibility of installing an ultrasonic emitter in an already manufactured car and to prove the possibility of cleaning the exhaust gases of an internal combustion engine through the action of an ultrasonic wave due to coagulation and examining the optimal regimes of its work. The existing theoretical solution to describe the proposed process was analyzed. A Mercedes-Benz M-Class ML 270 CDI MT car with the OM 612 DE 27 LA Diesel engine was used for the experiment. An ultrasound generator and an ultrasound emitter were connected to the muffler. The stand was connected to the car via the inlet with a rubber hose that directs the exhaust gases out of the car. The crankshaft speed of the engine was changed in the range of 750 to 1250 rpm, which corresponds to urban conditions when cars are moving in heavy traffic jams. The content of CH, CO, CO2, and O2 in the exhaust gas of the vehicle was determined as a function of the crankshaft speed without ultrasonic exposure and with ultrasonic exposure at an ultrasound frequency of 25, 28, and 40 kHz. The results of the experiment showed that the introduction of an ultrasonic emitter into the muffler reduced the smoke content of the gas, increased the oxygen content, and reduced the amount of carbon dioxide in the exhaust gases. With an increase in the ratio between the ultrasonic frequency and the angular velocity of the engine crankshaft (f/ω), the smoke content of the gas also decreased. At the maximum values of ultrasonic frequency and angular velocity of the engine crankshaft selected in the experimental studies, the minimum value of the ratio of gas smoke indicators was achieved, and the degree of purification was 10–13%. Such results correspond to the condition of optimal operation of the ultrasonic muffler, where the ratio of gas to smoke values should tend to a minimum. These results confirm the potential of using ultrasound as a method for cleaning exhaust gases and underline the need for further research in this area. Full article
