“…In modern studies, issues related to the assessment of losses from measurement errors have considered from the standpoint of assessing the risks and opportunities of the process (Koksal et al, 2013;Koksoy et al, 2019). This approach makes it possible to consider measurement processes as processes of an enterprise management system and manage them in accordance with the requirements of ISO 9001 (Leonov & Shkaruba, 2020a).…”

Many enterprises, including repair ones, face the problem of losses due to measurement errors. It has established that the number of losses from the measurement error has affected by the type (error) of the measuring instrument used, the dispersion of the controlled parameter (the distribution law, the scattering zone), and the features of the technological process. The article presents a generalized theoretical mathematical model developed by the authors, which describes the procedure for the formation of losses from measurement errors. The developed model has adapted in relation to repair production, using the example of controlling the diameters of the main journals of the crankshaft of the YaMZ-238 engine. The approbation of the developed technique made it possible to determine the losses from the measurement error in the control of the root diameters of the crankshaft journals using various measuring instruments. It has established that the greatest losses have obtained when using measuring instruments with the largest error, and the smallest -with the smallest error. The use of a more accurate measuring instrument instead of the recommended one will reduce the losses from the measurement error during the input control of new crankshafts in the repair shop by more than 77%.

“…The total radial runout as the geometric sum of vector links in the form of a dynamic component is determined by the expression inferred from dependence (1) where n is the number of links that the design engineer regards as radial runouts. 0.5 , The main point in determining the total misalignment is the competent composition of the dimensional chain and revealing the vector links and the links in the form of clearance, which will further specify the accuracy and the reliability of the calculation of the value to be determined.…”

“…In machine design and manufacture, every available resource is employed to create reliable and precise joints and frictional pairs [5,6]. In operation, the precision of joints under large loads varies in a complex manner on account of wear [7][8][9]. As a result, engine power and durability decline.…”

Influence of Cavitation on the Working Surfaces of the Cylinder–Piston Group in a Diesel Engine during Maintenance

When a diesel engine runs on water-fuel emulsion, carbon deposits break down on account of microimpact by the fuel droplets in the emulsion. The evaporation of the droplets depends on their diameter, the gas pressure, and the size of the bubble cavity. Removal of the deposits increases the mean compression ratio in the cylinder by 8% and the engine's power by 11%. Fuel consumption declines by 10%, and the smoke content of the exhaust gases declines by 16%.
