Determining the Pressure Losses in the Main Oil Line and Injectors of the Lubrication System of Diesel Engines of Heavy Vehicles: Numerical Simulation

This article presents the results that have provided a methodical basis for designing a digital twins of the main oil line and injectors of the lubrication system of a diesel engine. At the first stage, a CAD model of the oil line and injectors of the engine lubrication system was constructed. At the second stage, a fullscale computational model of the main oil line and injectors was verified using experimental data, which made it possible to create feedback for the digital twin. With the use of the calculations conducted, recommendations were suggested how to improve the accuracy of designing digital twins of the main oil line and injectors of the diesel engine lubrication system.
