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 investigates the increasing use of alternative fuels in internal combustion engines, a phenomenon that has experienced significant growth in recent decades due to the heightened interest in reducing atmospheric pollution. Although the pollution level associated with alternative fuels is generally lower compared to fossil fuels, it is essential to emphasize that the pollutant impact of alcohol-based fuels depends on various factors, such as engine technology, mixture composition, fuel quality, and usa...

Reducing air pollution is a major objective of road transport, the most important consequence of this reduction being the decrease in the number of illnesses and, implicitly, a better quality of human life. To achieve this goal, researchers- efforts have been directed towards reducing the quantities and treating the exhaust gases of vehicles equipped with internal combustion engines. It is important to note that the reduction of environmental pollution must also aim at decreasing the emissions of particles that ar...

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 ...

The main cause of air pollution from vehicles is related to the harmful emissions from engines, manly associated to the petrol industry and internal combustion engine manufacturers. As mention into the technical literature, the pollution emitted directly from engines is not the only cause of concern. Besides the liquids obtained from petrol (fuel and oils) and the ones used for air conditioning, the particles thrown off from brake pads is the third cause of air pollution from components of vehicles. It has been re...

Pollution and its effects on the environment have been at the centre of debates on the global stage, with growing concerns from researchers and the public. A major source of pollution is polymeric materials, which are increasingly used in various industries because of their similar properties to metal. If, in the case of polymeric thermoplastics materials we have recycling and reusing technologies when they reach the end of their lifespan or they break, not the same can be said about polymeric thermosetting materi...

Transport sector is a fundamental component of the human society. The importance for both the economic and social activities reveals from the fact that through this sector the movement of goods and people is performed in order to satisfy the material and spiritual needs of the society. However, in long term, the transport sector has a significant role in degrading the quality of the air and witch affects directly or indirectly the health of the population. In the period 2007-2018 there was a significant increase i...

The worldwide exponential increase of vehicles in operation generates, in addition to meeting transport needs, serious problems with environmental pollution. Vehicle pollution means not only pollution with exhaust emissions, but also tire pollution. Microparticles resulting from the interaction between tire and driveway or waste tires have a negative impact on the environment, regarding air, water and soil pollution. Solutions to reduce this type of pollution are not only the subsequent treatment or reuse of waste...

The emergence and development of the automotive market for electric vehicles to the detriment of motor vehicles with internal combustion engines has generated a series of controversies regarding the environmental pollution. In response to the development of the electric vehicle and the increasingly restrictive pollution standards, manufacturers of classic cars have designed cars with increasingly lower emissions of toxic gases. The electric vehicle emerged from the need to minimize air pollution in major cities an...

This paperwork makes an analysis of the influence that the noises and the vibrations have on a biomechanical model on the human body at different frequencies. Besides the harmful influence on the hearing acuity, the noises have also a harmful effect on the organism through the appearance of some changes on the physiological balance. Driving the car generates noises and them being received by the driver is done consciously, with pathological implications long-term. The harmful effects of the noises are amplified by...

This paper addresses an analysis on atmospheric pollution done by road vehicles. The substance emitted by vehicles that are present in the air, depending on their quantity and concentration, affects our health, generates discomfort and alters the environment. Global warming, or the greenhouse effect, since a certain period of time, is increasing from year to year. The recent increasing in registrations of vehicles which work on conventional fuels from the past few years (diesel oil, petrol) have led to a worrisome...

The presented paper identifies a potential factor that can amplify the atmospherically pollution due to drive?s biomechanics through the actuating devices and car controls. Most of the car drives neglect the operating techniques suggested by the manufactures. Thus, the overwork of the internal combustion engine amplifies the pollutant emissions. The driver position and the level of pollutant emissions can also be influenced by the heeled shoes. The delayed action of the clutch pedal and the delayed gear change lea...

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...
