The article considers the Lorentz attractor in aviation engine control systems (AECS) to obtain the necessary characteristics of the starting system and the laws of fuel supply, and to determine the emission characteristics. The defined behavior of the control system allows to optimize the control program of adjustable elements of the flowing part of the gas generator in transition modes of operation; to get a full picture of the starting characteristics of the developed engine, including reserves of gas-dynamic stability (GDS) in the starting modes; to establish the necessary programs for regulating the guide devices (GD), air bypass from the compressor; to select the required starter power, start-up cycle and fuel supply program in ground, alpine and flight conditions at the expected temperatures of air, fuel and oil in operation. Euler's and Runge-Kutta methods, Lorentz attractor are considered as the main approaches to mathematical modeling of AECS. The script of the interface of the modeling program includes the possibility of two-level modeling of the flowing part with the properties of end-to-end automated calculation: input of initial data and calculation of thermodynamic parameters of the engine; design of the flowing part of the engine based on the node approach; strength design and mass analysis; export data to files for CAD systems for further processing and interpretation.

“…However, their disadvantage is not the whole range of fault coverage, but only a small part of it, which obeys the logical structure of the algorithm. Most of the failures of system elements and engine components remain out of reach [4][5][6]. Actually, this forces the developers of diagnostic equipment to search for new ways of uncovering the uncertainty of connections in the process of diagnosing and developing instrumentation [7,8].…”

One of the priority directions in the development of instrument diagnostics of car engines is test diagnostics. The main advantages of such testing are: significant coverage of the diagnosed engine systems; high informativeness and reliability of the diagnostic process with general simplification of the diagnostic process; reduction in the number of diagnostic parameters. In addition, one can achieve high automation of diagnostic process operations, adaptation of diagnostics interfaces and high intuitive level of functioning algorithms. The authors developed a diagnostic instrumental tool -a loader for gasoline engines (LGE-3), as well as a device for fixing the position of the throttle. The loader of the gasoline engine LGE-3 allows us to create any load and speed mode. Load on the cylinder is provided due to a complete shutdown of fuel in any cylinder and by disabling individual fuel cycles in the selected cylinder. The results of experimental studies on the example of electromagnetic injectors have shown a high efficiency of test diagnostics. The diagnostics modes at 25 and 70% degree of throttle valve opening are designed and recommended.

“…Ideal conditions for the operation of vehicles were in these studies. However, the realities of operation show that, in most cases, car owners, car fleets, and automobile enterprises are unable to provide ideal conditions for the operation and maintenance of vehicles [21][22][23][24]. The high complexity of troubleshooting in the main ICE systems affecting the environmental performance of vehicles also encourages the development of new troubleshooting methods to maintain the highest environmental vehicle class [25][26][27][28].…”

In modern transport, environmental control plays a key role in shaping the strategy for managing the technical condition of nodes and systems. The first step in reducing the toxicity of exhaust gas emissions was the introduction of Euro standards, successively from Euro-0 to Euro-6. Accompanying the appearance of Euro standards, exhaust systems were supplemented with catalytic converters, which deactivated most of the harmful emissions. Oxygen sensors also began to play a key role, the installation of which resulted in the appearance of feedback. Thus, the global automotive industry is closer to the controllability of the engine output parameters. However, there are not enough parameters, operating modes, and additional controls available for this purpose. The presented studies used a new method of selective control of exhaust gases in each cylinder. The following parameters were used for monitoring: the crankshaft speed, complete and partial (cycle-by-cycle) disconnection of cylinders, O2, CO, CO2, and CH. The mode was provided by the number of the engine's disconnected operated cycles and the crankshaft speed. The control was performed by the internal adjustment of the fuel supply under the influence on the injection duration of the electromagnetic nozzle. During the research, we established the minimum values of the exhaust toxicity parameters during the test effects. This method with a combination of modes and parameters allows us to reduce the toxicity of exhaust gases and to improve the efficiency and effectiveness of vehicles.
