“…Solid microparticles are getting into the atmosphere and create smog in city centres. A vehicle with removed diesel particulate filter is subsequently degraded to below the emission standard EURO 4 [5]. If the filter is removed from the exhaust pipe, it is necessary to carry out an intervention into engine management in order to stop the process of forced regeneration.…”

“…Corrected absorption coefficient is a value determined by the manufacturer and it is used for determining the maximum permissible value of smoke D MAX . The formula for calculating D MAX is the sum of corrected absorption coefficient and constant which is determined by guidance for the performance of emission control to the value of 0.5 m -1 [6,7].…”

Solid carbon (C) is produced during hydrocarbon fuels combustion by the molecules heat decomposition process in a local lack of oxygen. More reactive hydrogen consumed the part of oxygen in the zone of an oxygen-rich mixture, so carbon particles are not gaining access to oxygen. Solid carbon particles are bound to other various materials such as mechanical impurities, sulphates, condensates, and liquid fuel residues, some of them with high toxicity – such as polycyclic aromatic hydrocarbons (PAH). The cause of high solid carbon emissions is a significant inhomogeneity of the mixture up to the value λ = 0 inside the fuel droplets where oxygen absences up to λ = ∞ in the space where fuel does not even come. Therefore, solid carbon emissions highly depend on the quality of atomization of the fuel which is injected into the cylinder. The supply of oxygen required for oxidation is improved by increasing the total amount of the air in the cylinder. In Slovakia as well as in other countries (the Czech Republic, etc.), there have been recently multiple instances of removing catalysts from vehicles by services, deactivation of diesel particulate filters (DPF, SCR), or vehicle control units reprogramming (tuning), or a combination of the previous actions. From the perspective of a company and its interest, it is a large interference with vehicle design, and it also affects the relationship with the environment. From the perspective of society, it is irrelevant whether it is the individual's conduct or the conduct of certain groups. This article explores the possible solutions for checking the illegal diesel engines conversion due to deactivation of particulate matter filters in exhaust systems of diesel engines as well as the current legislation that covers this issue.

“…The emissions inspection station is a workplace specializing on performing motor vehicle emissions inspections. According to the size of premises and category of vehicles, their emissions system and the type of fuel for engine drive, emissions inspection stations are divided into individual types of workplaces at which individual types of emissions inspections are performed (Lenďák, 2013).…”

Vehicle emissions inspection represents a fast, relatively efective in terms of time and cost, and mainly comprehensive estimation of vehicle emissions. Procedurally, emissions inspection includes those inspection operations that focus not only on analysing exhaust gases but also on detecting the functionality and tightness of other engine components directly afecting the ecological friendliness of inspected vehicle‘s engine. Our study describes the results of vehicles inspected at an emissions inspection station for the reporting period. Based on the analysis of information obtained from the National Transport Authority of the Slovak Republic concerning the evaluation of vehicles according to individual categories, it can be alleged that the technical condition of vehicles of M1 and N1 categories is gradually improving.

“…According to the roadmap, the emissions should be cut to 40% below the 1990 levels by 2030 and to 80% below the 1990 levels by 2050. Globally, the road transport sector is one of the main sources of carbon dioxide emissions and pollution (Lenďák et al, 2013;Szabó et al, 2013); therefore, the reduction of emissions from this sector is one of the key objectives in order to meet the Kyoto Protocol and create a sustainable transport system (Fontaras and Samaras, 2007). In the European Commission's roadmap, the share of the transport sector is set to be reduced by 60% by 2050 from the 1990 levels.…”

This paper presents a new approach for reducing the CO 2 emissions in the transport sector based on emission compensation. A cost-benefit analysis method of investments in photovoltaic parks at petrol stations is used, which accounts for all the initial investments and maintenance costs in terms of expenses. The benefits are divided into financial and ecological. The method has been implemented in the specialised cost-benefit analysis tool, and an analysis has been performed for the city of Ruse, Bulgaria. Risk analysis on the influence of the main risk factors -the price of conventional energy and the buying price of energy from renewable energy sources is also performed. The results showed that investments in photovoltaic parks at petrol stations could pay off within 6 to 9 years in the more likely scenarios. The investment could reduce the CO 2 emissions, related to the petrol station, by 10% to 37% depending on the scenario and the criterion used.
