Abstract

Problem. The work is aimed at increasing the reliability, accuracy, information content and depth of the process of diagnosing the cylinder-piston group of the engine. For this, an automated diagnostics system has been developed, which includes a system unit with a monitor, special software for measuring and processing information, a measuring analog-digital module, adapters for connecting to the engine. The diagnostic system allows you to record the change in pressure in the cylinder with each degree of crankshaft rotation with an error that does not exceed 1.7%. The system also allows you to save, reproduce and transfer diagnostic information in digital, graphic and text form. It can be used for expert studies of the technical condition of engine mechanisms. Purpose. The purpose is to develop and improve a digital stand for diagnostics of the tightness of a car engine combustion chamber. Methodology. The complex process of diagnostics of mechanisms ensuring the tightness of its chambers is considered. The current digital technology is used to measure the pressure in the camera. To improve the accuracy of diagnostics, a digital system of rejection of diagnostic information is thoroughly implemented. Experimental tests are conducted, as well as an expert advice on the technical definition of the engine, its mechanics and details. Results. The system for diagnosing the tightness of the combustion chamber has been developed and tested, which includes a modern analog-digital diagnostic stand and a technique that will allow the whole process of connecting the sensor to the processing of the form of diagnostics to the vehicle. The system will secure a faster process of diagnostics of an engine during 20-30 min. At the same time, the decrease in the size of the grip does not exceed 1.7%, which is 0.3-1.3% less than with the known analogs. Originality. Thanks to a more advanced digital system for measuring the pressure in the engine cylinders in the work the curves of changes in this pressure at each degree of rotation of the crankshaft and at different speeds of its rotation are obtained. Practical value. Developed and improved digital stand and method of measuring the pressure in the cylinders of the engine can be used for diagnostic work at car service stations, as well as for automotive research (expertise) to determine the development of fault mechanisms engine.
