Abstract

Scientific substantiation of the design and simulation techniques for one of the understudied aspects of oil supply, namely, jet supply of engine oil from the gaps of the rotating journal bearing to the “cylinder–piston” pairing of a high-speed four-stroke universal diesel engine, is given. The simulation resulted in visualization of the trajectory and zones of oil ingress on the friction surfaces of parts of the cylinder–piston group presented in this article, as well as a quantitative assessment of the oil volume in these zones and in the crankcase. The simulation technique and the results of its application can be of both scientific and practical interest for specialists in the field of lubrication design and reliability of piston machines.
