This research aims to conduct a descriptive statistical analysis to identify the statistical correlation between categories of new and second-hand vehicles registered for circulation in Romania and various health conditions associated with atmospheric pollution. Currently, a significant challenge for the global community lies in mitigating the impact of atmospheric pollution, considered a crucial factor both in terms of global climate change and its impact on public health. One major source of atmospheric pollutio...

This research aims to conduct a detailed analysis of the necessity for generating electrical energy using conventional methods, simultaneously assessing the impact on water quality. Wastewater, originating from fluids used in industrial processes or households, contains various impurities and is discharged into the natural aquatic environment (such as rivers, lakes, or the Black Sea) or onto various lands, either with or without prior treatment. The production and utilization of primary energy raw materials, such ...

The purpose of this work is to explore the potential for predicting and improving the fuel efficiency of vehicles with thermal engines, especially in the context of reducing exhaust gas emissions that contribute to environmental pollution. With rising fuel costs, consumers need to make informed decisions about the fuel consumption and environmental impact of purchasing vehicles with internal combustion engines. To achieve this goal, the researchers utilized artificial intelligence and created a model using neural ...

Nowadays, due to environmental pollution, finding and using alternative sources of energy is a priority for any economy. For this purpose, scholars from all over the world are focusing on finding the best alternative sources of energy. One example is the wave energy. This natural source is characterized by being renewable, inexhaustible, not polluting, thus is not contributing to global warming by generating emissions. Yet such a resource is extremely variable. The aim of this paper is to analyze the Black Sea wav...

The aim of this paper is to present a detailed method for exhaust gases recirculation system (EGR) diagnostics for a compression ignition engine. In this paper, we analyzed the gas index coefficient, Kmax [m-1], using a Johnson Controls пїЅ Ultimax 600 opacimeter while the vehicle was in static state but at different engine speeds. The minimal rotation speed, nmin, had a value of 822 [rpm] while the maximum, nmax, 5006 [rpm]. In this case, was used the absorption process for measuring. The dynamic test imply using...
