The paper considers issues of increasing the efficiency of application of measuring expert systems (MES) that solve the problem of reducing power losses of motor and tractor internal combustion engines (ICE) in production conditions due to changes in their technical condition. MES carry out operational control of the energy parameters of the machine and tractor fleet for taking timely repair and maintenance actions. A methodological approach is proposed for creating an automation system for the development of MES, which increases the efficiency of the formation of MES due to the existing expertise in this subject area. The methodological basis of research is a dynamic method for diagnosing ICE. This method uses a test dynamic effect on ICE, which is the most practical for assessing the state of tractor ICE in production conditions, as well as computer modeling of the ICE work processes in order to find informative diagnostic indicators characterizing energy parameters. On the basis of the proposed target function, the software was determined in the form of the model describing a variety of system elements, their features and states, as well as links between them. Information provision was organized, carrying out the functions of collecting, processing and providing information upon request. A method for constructing a logical scheme of the development algorithm MES was formed, which formalizes the process of solving interrelated problems in the synthesis of various structures of hardware and software based on a set of mathematical models. On the example of modeling an ICE unit – a working machine, the effect of varying the input parameters of the model was estimated: torque effects and resistance moments on the diagnostic parameters of the technical state – angular velocities and accelerations. The use of computer modeling of ICE working processes using this methodological approach made it possible to create a digital technology and a measuring system for automated energy monitoring of the tractor fleet of an agricultural enterprise. The computer structural diagrams of ICE and MES models can be used in diagnostic complexes. This will make it possible to increase the accuracy and reliability of determining the state of the internal combustion engine and the mechanisms and working machines aggregated with it, as well as improve the quality of the work they perform.

High Quality

The article reviews four existing technologies for replacing engine oil and a method for determining its suitability for improving economic efficiency. It is established that the oil is replaced according to the need in accordance with the defect indicators. This technology of oil condition is characterized by a more complete use of its resource. The frequency of replacement is determined by the indicators of condition, which is monitored by special sensors built into the engine lubrication system. However, the difficulty of using this technology is due to the lack of high-quality devices for monitoring the state of running engine oil in the engine.

Small Vessels

The problem of current monitoring of the state of an internal combustion engine is especially relevant for water transport. Usually, in complex systems for monitoring the state of the cylinder-piston group (CPG) of cargo ships, many indicator indicators are used, such as temperature, pressure, vibration. For small boats, such a complex system with integrated sensors is redundant. The purpose of this study is to develop a system for vibration monitoring of the state of internal combustion engines of small vessels based on the open-source platform Arduino Uno with data transfer to cloud storage. In the article, the authors have developed a connection diagram and software for a vibration monitoring system for internal combustion engines of small vessels. The theoretical basis of the developed system is based on the FFT analysis technique based on the fast Fourier transform. The developed design is based on the Arduino Uno microcircuit. The data transfer takes place using the ESP8266 Wi-Fi module for real-time output on the Django server and storage in Google Sheets. The choice of such a system is due both to the need for the existence of a system for the current display of indicator parameters with the establishment of the nature of malfunctions and signaling of critical operating modes, and the need for the accumulation of scientific data for researching the operating mode of the engine. It will be useful for scientists and designers of ICEs of small vessels. It has been established that the use of the modular Arduino system will make it possible to vary the properties of the vibration monitoring system within a wide range by using various types of sensors (KY-038 and LM393). The method of data transmission of the vibration monitoring system at the software level has been improved by using software blocks from three open-source projects based on Arduino. The developed scheme can be developed for use in vehicles, as well as monitoring of other types of engines. This can become the basis for the accumulation of data, which will make it possible to more accurately diagnose deviations in the operation of the internal combustion engine of small vessels based on general statistics, and not only data from one engine, as in similar systems for cargo ships.
