The solution of the problem of designing, developing and further using automated test systems (ATS) of internal combustion engines (ICE) involves, first of all, analyzing a number of important requirements for the development of technical, mathematical, software, information, linguistic and organizational-methodological support of an automated system. Currently, the need for widespread implementation and operation of automated systems in real test conditions of stations of production plants and design and research institutes imposes some restrictions on the design of automated tuning tools for real technologies of testing various types and modifications of internal combustion engines. This circumstance is based on a sufficiently large number of tested engines, units and assemblies of various modifications, as well as the need to gradually eliminate errors in existing algorithms, including the creation of new test algorithms, in particular, when conducting research and development tests of engines. Requirements of real engine operating conditions cause a constant increase in the technical level of the modifications produced and lead to the fact that the nature of the cost of testing when designing new types of engines increases each time. These costs are the highest in the absence of a relationship between the levels of production automation and research and development. The result is that the automation of technological processes for testing internal combustion engines is one of the most important tasks of increasing the technical level of production and the quality of the engines produced.
The growth of the power supply of all industries throughout the world has caused a wide development of enginebuilding, including the production of engines of various types, and therefore the problem of improving them is of great importance . The solution to the problem of improvement is more dependent on the compliance of the fuel injection process with the work process that takes place in the engines . For continuous management and control of the process of the internal combustion engine, it is necessary to implement a controller . The electronic control unit (ECU) allows you to control solenoids injectors. It monitors and processes the various input signals of the measuring sensors . The basic data are the engine’s crankshaft speed and load, which the driver can directly influence with the accelerator pedal . Controlled parameters also include air temperature, fuel, coolant and pressure of the turbocharger . These basic functions can be complemented by a variety of other operations designed to enhance convenience . The controller must meet the stringent requirements for the reliability of work compensation and the identification of malfunctions in the operation of individual components. It is also intended to facilitate the diagnostics of malfunctions of the engine and its fuel injection system . To check the quality of the assembly and test ICEs equipped with an electronic controller, it is necessary to introduce a technical complex at the manufacturing plant that provides automatic control of the ICE technological modes of operation .
Based on the above, we can conclude that the developed test system allows us to effectively test an engine. Of particular interest is the possibility of comparing the compliance of the current parameters obtained as a result of tests with the parameters specified in the design of the engine and the vehicle as a whole
