In the calculation method and mathematical apparatus for assessment of the complex fuel and ecological criterion of Prof. Igor Parsadanov has been improved by considering the mass hourly emissions of sulfur oxides with the exhaust gases flow from the reciprocating ICE as a toxic pollutant. The purpose of the study is obtaining the values of complex fuel-ecological criterion that characterize the ecological safety level of diesel engine exploitation process considering the emissions of sulfur oxides as a toxic pollutant. The European Steady Cycle (according to UENCE Regulations № 49) was used as the exploitation model. A set of initial data has been obtained for the calculated criteria-based assessment of the ecological safety level of the exploitation process of power plants with a reciprocating ICE on the example of the autotractor diesel engine 2Ch10.5/12 based on the results of data processing of bench motor tests. The calculated assessment of specified criterion values considering sulfur oxides emissions was carried out. It has been detected that the value of the fuel-ecological criterion for the basic variant of considering the emissions of sulfur oxides, i.e. considering the values of sulfur content in motor fuels and oils and burning oil consumption, typical for diesel 2Ch10.5/12, differs for the variant that does not take into account this ecological safety factor, on average by 6.6 %. For the option that takes into account the modern requirements for the sulfur content in technical fluids and the technical level of modern reciprocating ICE, this difference is 0.5 %. The identified dependences are described by formulas by the method of least squares. The scientific novelty of the obtained results is that the approach of Prof. Igor Parsadanov received further development for criteria-based assessment of fuel-ecological efficiency of autotractor diesel engines exploitation process as a part of power plant considering the mass hourly emissions of fulfur oxides with RICE EG flow as the toxic pollutants and also methods for determination of such emissions and ponderability of such pollutants in direction of application of this mathematical apparatus for standardized steady testing cycles.

In this study, the author has improved its previously proposed methods for determining the value of mass hourly emissions of benzene(a)pyrene and polycyclic aromatic hydrocarbons in diesel engine exhaust gases flow. The purpose of the study is to obtain the values of complex fuel-ecological criterion that characterize the ecological safety level of diesel engine exploitation process considering the emissions of benzo(a)pyrene and polycyclic aromatic hydrocarbons as toxic and carcinogenic pollutants. The distributions of such emissions have been obtained over the field of a 2Ch10.5/12 autotractor diesel engine operating modes field and over the modes of standardized steady testing cycle ESC. The mathematical apparatus and method of application of complex fuel-ecological criterion of Prof. Igor Parsadanov have been improved. The author has obtained the distributions of these indicator values of ecological safety level of power plants with reciprocating ICE exploitation process over the field of 2Ch10.5/12 autotractor diesel engine operating modes of and over modes of standardized steady testing cycle ESC, as well as its average operating value. It has been established that, average operating values of Kfe criterion and the δKfe effect for all investigated variants of accounting for mass hourly emissions of B(a)P and PAH in diesel engine exhaust gas flow are almost identical and reduce the value of the Kfe criterion on 29 – 32 % – from 63 ‰ up to 42 – 45 ‰. The scientific novelty of the obtained results is that the approach of Prof. Igor Parsadanov for criteria-based assessment of fuel-ecological efficiency of autotractor diesel engines exploitation process as a part of power plant considering the of mass hourly emissions of benzo(a)pyrene and polycyclic aromatic hydrocarbons with RICE EG flow as the toxic pollutants and also methods for determining of such emissions and ponderability of such pollutants received further development towards in direction of application of this mathematical apparatus for standardized steady testing cycles.

torists compared to petrol or diesel cars. Also shown are the data of hybrid vehicles for comparison with petrol cars of the same class. Conclusions that buying a car with a hybrid power plant (HPP) is economically preferable to purchasing a similar car with a conventional ICE. However, hybrids are losing their competitive advantage due to the improved efficiency of gasoline-powered vehicles. Therefore, there is need to assess the fuel efficiency of vehicles with hybrid power plants. For evaluation of the fuel efficiency of vehicles with HPP a method is proposed of evaluating their fuel efficiency. To calculate the fuel efficiency of hybrid cars the following data are required: total mileage of the hybrid car, mileage of the hybrid car in electric mode, car mileage in hybrid mode, power consumption of the battery of a hybrid vehicle to overcome 1 km in electric mode, cost of 1 kW of stored energy in traction battery from a standard mains, fuel consumption in hybrid mode, cost of fuel. It is shown that, the less the daily mileage of a hybrid car and lower the average speed, the cheaper is the km of its run. Unlike vehicles with ICE, in which high consumption of fuel occurs on the first kilometers at low average speeds, which is associated with intensive heating up of the ICE when its temperature reaches the nominal value and with the fact that the car in traffic jams has a low average speed (up to 30 km/h), and the ICE works inefficiently. synchronized with the process of the experiment is solved by existing methods of concentration and interactive presentation of information. The purpose of this study is to develop an LED-board with an automated ticker-system for prompt display of information during bench tests of internal combustion engines. The developed design is based on the MAX7219 microcircuit. Data transfer occurs using the UART interface via the Bluetooth mod-ule HC-06. The driver is controlled via the SPI interface (mode 0). The choice of LED display is due to the possibility of using monochromatic light emitting diodes as point sources of radiation with a wide range of options for regulation of luminescence parameters. This is achieved when using high-performance LED clusters Pure-Green (525 nm), Ultra-Red (660 nm), Blue (470 nm). In the article the authors developed a constructive scheme of LED board for displaying the data of bench tests of internal combustion engines. The principle of the moving series (ticker), which is widely used in stock exchange analytics and advertis-ing, is informative enough to reproduce the results of the internal combustion engine test bench tests. It has been determined that the application of the Arduino modular system will allow to vary the properties of the data display system to a wide extent and, when developing special software, to conduct test analytics using adaptive neural networks.
