The article is devoted to the analysis and environmental assessment of changes in the regulatory and technical documentation governing the quality of motor fuel in Russia. The quality of motor fuel is understood as a large set of parameters that determine the efficiency and safety of its use for its intended purpose. Ecological safety is revealed as an important component of quality, which is closely connected with other motor characteristics of fuel. The data is analyzed on the influence of additives, supplements and hydrocarbon composition, that is everything that determines the quality of motor fuel and the level of its environmental hazard. The significant role of the environmental component in the development of requirements for the quality of motor fuel has been established and a retrospective has been defined in improving the regulatory and technical control of this issue. A comparison of Russian peculiarities and their connection with global environmental trends in the development of requirements for the quality of motor fuel are provided. The ecological effect of the improvement of the Russian regulatory and technical documentation in terms of the quality of motor fuel has been evaluated.
The UNECE Regulations (EURO standards) are constantly being amended to toughen the standards for mass emissions and the amount of controlled pollutants, as well as to complicate test cycles in order to link them to actual operating conditions in a better way. In addition, the amendments take into account the recently widely used hybrid and gas cylinder vehicles. EURO-5 in comparison with EURO-0 repeatedly reduces emissions of pollutants: CO – 2.72 … 9.3 times; NOx – 2.4 … 7.9 times; PM dispersed particles – 20 … 50 times. A significant variation in numbers is due to the fact that for each category of PBX (taking into account the type of fuel) their its own standards are applied [2, 5]. The theoretical basis. It is important to note that meeting the most stringent environmental requirements for vehicles, nowadays it’s EURO-6 in Europe, is impossible without appropriate fuel, the physicochemical and motor properties of which are also strictly regulated by the European Standards EN 228 and 590 . Let us review the process of development of requirements for the quality of motor fuel in Russia (Figure 1) and estimate the impact of its environmental component.
Thus, the transition from GOST 2084-77 to the ТР CU 013/2011 regarding the quality of motor fuel should be considered as a transition to another level – the level of safety for humans and the environment.
