The purpose of the experimental studies is to check and refine theoretical developments on the multi-level system of ESM diagnostics.

Achieving this goal requires completing the following work steps:

• Development of specific experimental research methods;

• Selection and development of technical diagnostics tools, equipment and devices for recording output indicators;

• Carrying out each of the stages of experimental research according to the developed private methods;

• Determination of the limit values of diagnostic parameters;

• Verification of the adequacy of theoretical developments.

The obtained results of the experiment are used to test theoretical developments and justify diagnostic conditions for monitoring the state of the internal combustion engine ECM(3).

The measuring instruments used for this purpose must provide an accuracy of 0.2-0.3 of the value of the tolerance field of the controlled parameter.

The standard program "Motor Tester" is prepared for testing and connected to the vehicle system in accordance with the rules set out in the operating instructions.

To ensure the uniformity of the experiment, objectivity and compare ability of the results obtained, the remaining values of the experimental ICE with distributed fuel injection are provided unchanged. During the entire research cycle, the following conditions were observed: all experimental test data are brought to atmospheric conditions as close as possible to normal: air tempera-ture293 K (+20 °C);barometric pressure B = 101.3 kPa (760 mmHg); water vapor pressure 1.2 kPa; fuel temperature at the input to the motor power supply system t=+20 °C / 66, 61/.

Other restrictions are reflected in the developed private methods. Based on the previously presented multi-level engine diagnostics system with ECM, a technological process diagram is developed, as shown in Figure 1.1(4)

The assessment of complex indicators includes obtaining data on the state of the internal combustion engine based on power, fuel consumption and environmental indicators. A portable PC with the standard program "Motor Tester" is installed in the car and connected via an RS-232 cable and an adapter to the on-board diagnostic pad. The adapter is powered by the car mobile battery. The connection diagram of the PC to the vehicle is shown in Figure 1.2.(6)

The assessment is made when driving in acceleration mode with the throttle fully open in 3rd gear on a horizontal section with an asphalt-concrete surface. Initial conditions: the speed corresponds to 40 km / h, the crankshaft speed is 1000 rpm.

A flowchart for getting information from the engine is shown in Figure 3.(2)

Variables obtained with the vehicle in driving mode are shown in Table 1.

Further processing of data obtained from the standard program "Motor Tester" is performed manually by the operator in the "Write down" mode. In this mode, by moving the visor, you can view the values of seven diagnostic parameters simultaneously at any time. The obtained data are entered into the program" Power, specific

fuel efficiency and ecology" developed by the author, presented in Appendix A, to obtain the values Ne, gof ne, g e,, Pэкоп depending on the speed of rotation of the crankshaft. This program provide number of fixed values used for calculation, which are shown in Table 1.2(5)

Data on atmospheric conditions is also entered into the program, so that the obtained parameters can be compared with each other. The program outputs parameter data in the form of tables and graphs(1).

The performance and economic parameters of internal combustion engines depend on environmental parameters such as pressure, humidi typa, and ambient air temperature. GOST 14846-69 and GOST18509-73 regulate the standard conditions given in the general meth-odology(10).
