“…Taking in to account the features of the technology of electroerosion treatment, it was used to restore the spline surfaces of synchronizer carriages [9,10]. The electroerosion method allows processing metals with any surface hardness, which simplifies the recovery technology, which is reduced to surfacing worn surfaces with wire with high hardness, for example, HRC 50-55, and further electroerosion treatment of the deposited surfaces.…”

The internal combustion engine is the most expensive component of a car, which determines the reliability and efficiency of its use. Studies show that one of the most common reasons for the failure of KAMAZ diesel engines during operation is the underutilization of the crankshaft resource due to wear of parts and couplings that limit its resource. An increase in the resource of crankshafts can be achieved by improving the technological processes of restoration and repair. Full utilization of the resource of KAMAZ nitrided crankshafts is possible by surfacing worn journals only after removing a nitrided layer up to 0.4 mm thick from the journals surface using specialized equipment for electrical discharge machining. Electrical discharge machining is based on the removal of material particles from the surface by an electric discharge pulse between electrodes immersed in a liquid dielectric, in the channel of which a high-temperature plasma is formed.

“…According to EURO standards, it defined four ecological classes of unleaded gasoline produced in Russian Federation (GOST R 51313-99 is canceled, which automatically excludes the production of leaded gasoline). Regarding GOST R 51105-97 and GOST R 51866-2002, Russian Federation Technical Regulations were of reference character, that is, they referred to them in terms of the range, requirements for physical, chemical and motor properties of gasoline produced, as well as in terms of methods for testing them [6][7][8][9]. At present, the Technical Regulations of the Customs Union "On the requirements for vehicle and aviation gasoline, diesel and marine fuel, jet engines fuel and residual oil" are in force -ТР CU 013/2011 (effective in Russian Federation since 2015).…”

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.
