Special Issue Information

Dear colleagues,

The online journal Energies is looking for contributions to a Special Issue on “Advances in Real Driving Emissions Measurements Using Portable Emission Measurement (PEM) Systems”. While the technology that underpins PEM Systems has existed for some time, many useful advances in understanding real driving fuel consumption and emissions have accumulated since the introduction of new type approval legislation at the Euro 6 stage. Despite these impactful advances, many knowledge gaps remain within the transport emissions field that could be successfully addressed using PEM systems. As the move towards Euro 7 emissions legislation intensifies, remaining knowledge gaps within the field that could be targeted in this Special Issue include but are not limited to PEMS studies that address:

  • Alternative powertrain technologies, e.g., hybrid electric vehicle systems;
  • Applications investigating alternative fuels in a real driving emissions context;
  • Non-road engine PEMS applications including shipping and off-road equipment;
  • New advances in PEMS measurement technology, such as mini-PEMS and PEM Systems with higher sampling frequencies.

Other topics are welcome but have to conform to the requirement of being a PEMS-based application so that the papers in this issue can form a coherent set. I look forward to seeing your contributions in this rapidly developing field of emissions research.

The deadline for submissions is 30 June 2021.

Yours sincerely, 

Dr. Nicholas Surawski
Guest Editor

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. 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.

On-road driving tests are performed to determine the emission of harmful exhaust compounds from vehicles. These primarily include carbon dioxide, nitrogen oxides, and particle number. However, there is a lack of indicators that combine the first three substances that are the most important in assessing the environmental aspects of vehicles. The purpose of this article is to indicate the possibility of assessing emissions in real driving conditions from light-duty and heavy-duty vehicles of different categories. In order to do so, a portable emissions measurement system (PEMS) and an instrument for measuring the particle number were used. The tests were carried out on routes designed to comply with the requirements and regulations laid down in the European Union legislation. On-road emissions of carbon dioxide, nitrogen oxides and particle number have been determined. Factors have been determined as the multiplication of these compounds for each vehicle category in three phases of the test: urban, rural, and motorway. A new way of assessing emissions from vehicles using new factors has been proposed. Full article

Increasing the biodiesel content of diesel fuels is encouraged because of its reduced carbon footprint.

Increasing the biodiesel content of diesel fuels is encouraged because of its reduced carbon footprint. Pure rapeseed methyl ester (RME)and used cooking oil methyl ester (UCOME) are characterised by well-to-tank greenhouse gas (GHG) reductions of 54% and 88% compared to pure B0 petrodiesel, respectively. Captive fleets such as public transport buses could benefit from these GHG reductions by increasing the biodiesel content of their fuel because they have a consequent yearly fuel consumption. The aim of this paper is to compare on-road tailpipe emissions of a diesel bus when increasing the biodiesel concentration in the fuel. The tests were carried out on a standard city bus belonging to the Euro V EEV emission standard that was equipped with a portable emission measurement system measuring NO, NO2, PN, CO and CO2 at the tailpipe. The bus followed the SORT which is representative of urban bus driving. The heavy urban on-road measurements indicated increased NOx emissions (24–26%), decreased PN emissions (43–45%) and slightly decreasing CO emissions for B30 RME and UCOME compared to B7. A measurement uncertainty analysis showed that the CO emissions were less reliable. Similar conclusions were drawn for the easy urban on-road bus emission measurements with smaller differences between B7 and B30 RME and UCOME. Full article
