“…The discussed topic has great development potential and should be continued with further analysis of other types of roundabouts, in terms of diameter, number of inlets, as well as the structure itself. Further improvement should also apply to the vehicle engines exhaust emissions calculation models because engines and vehicle construction are subject to continuous improvement, which affects generated emissions [54,55].…”

“…The variety of driving styles and characteristics of roadways in cities causes various emissions from vehicles. Fuel consumption, as well as exhaust emissions for different components of pollutants, among others CO2, CO, NOx (nitrogen oxides), THC, PM (particulate matter), is very diverse [1][2][3][4][5][6][7][8][9][10][11][12] and depends mainly on the speed, acceleration, gradient of the road and thermal condition of the vehicle's engine. One of the points where occur the biggest accumulation of vehicle traffic in cities is intersections.…”

Due to the increased emission of harmful exhaust components, in particular CO2 (carbon dioxide), CO (carbon monoxide), THC (total hydrocarbons), by motor vehicles, especially in the centres of urban agglomerations, it is necessary to create traffic simulation models that allow to estimate the emissions from road transport. One of the places where the largest accumulation of vehicles in cities occurs are intersections. This contributes to increasing the number of stops and repetitions of the acceleration and braking cycle, which has a direct impact on vehicle emissions. At the same time, roundabouts are intersections with specific traffic movement characteristics, therefore it is necessary to calibrate the simulation model beforehand. The aim of the study was to develop a methodology for modeling vehicle traffic at the roundabout and compare the combustion engines emissions resulting from vehicle movement on the example of the selected roundabout case studies. Vehicle traffic modeling was performed in the Vissim traffic microsimulation program based on real data. The comparison concerned the emissions for a two-lane and a turbo roundabout for the assumed traffic volume scenarios for properly calibrated simulation models. The results show that the performance of the simulation allows for the analysis of emissions and determination of its size for each of the roundabout inlets. It is also possible to determine the general dependencies e.g. the length of the queue of vehicles in relation to the emission of the analysed exhaust components. The analysis can be used as an introduction to changes in the guides for designing road intersections concerning vehicle emissions.

“…In 2015, the average emissions for the produced vehicles fell to the level of 120.7 g/km of CO 2 . However, these were data for emissions from homologation procedures 2 of 19 for the New European Driving Cycle (NEDC), which, compared to road data, significantly lowered the average values of emissions [19][20][21][22][23][24][25][26][27]. The differences in CO 2 emissions for the NEDC and the road test reached 30-40% [28][29][30].…”

The problem of global warming and the related climate change requires solutions to reduce greenhouse gas emissions, in particular CO2. As a result, newly manufactured cars consume less fuel and emit lower amounts of CO2. In terms of exhaust emissions and fuel consumption, old cars are significantly inferior to the more recent models. In Poland, for instance, the average age of passenger cars is approximately 13 years. Therefore, apart from developing new solutions in the cars produced today, it is important to focus on measures that enable the reduction in CO2 emissions in older vehicles. These methods include the adaptation of used cars to run on gaseous fuels. Natural gas is a hydrocarbon fuel that is particularly preferred in terms of CO2 emissions. The article presents the results of research of carbon oxides emission (CO, CO2) in the exhaust gas of a passenger car fueled by petrol and natural gas. The emissions were measured under the conditions of the New European Driving Cycle (NEDC) test and in real road tests. The test results confirm that compared to petrol, a CNG vehicle allows for a significant reduction in CO2 and CO emissions in a car that is several years old, especially in urban traffic conditions.

“…Over the past several years, numerous computational and experimental studies have been conducted to reduce the harmful pollutants (e.g., NOx and PM) emitting by diesel engines [3][4][5][6][7]. Recent experimental and numerical investigations show that many researchers still focus on using post-injection of diesel fuel to meet emission regulations in single and dual-fuel engines.…”

This paper presents a numerical investigation of the separate effects of post-injection characteristics in a heavy-duty turbocharged direct injection diesel engine under pure diesel combustion (PDC) and diesel-syngas combustion (DSC) operating conditions. Converge CFD code was used coupled with a detailed n-heptane/toluene/PAH chemical kinetic mechanism (consists of 71 species and 360 reactions) for diesel-syngas dual-fuel combustion simulation. A total of 36 strategies based on the post-injection characteristics (post-injection timing, fuel quantity, spraying pressure, and main-post dwell time) on the combustion characteristics, exhaust gas emissions, and engine performance under PDC and DSC conditions were investigated. Numerical achievements revealed that 40% substitution of diesel fuel with syngas significantly decreased particulate matter emission and enhanced the indicated thermal efficiency (ITE), compared to the baseline PDC case. However, carbon monoxide noticeably increased. In addition, retarding the post-injection timing prolonged the combustion duration and also reduced the nitrogen oxides emissions and ITE. By increasing the post-injection quantity up to 15%, the combustion process deteriorated, and carbon-based emissions such as particulate matter, carbon monoxide, and unburnt hydro-carbon in the exhaust gases increased under PDC and DSC conditions. Furthermore, increasing post-injection pressure (PIP) from 1000 to 1450 bar under both PDC and DSC conditions led to higher flame temperature, and as a result, the heat release rate peak point and temperature peak point for the second combustion event increased. However, at a PIP of 1600 bar, the ITE deteriorated under PDC and DSC operating cases.
