Evolution of tar deposits on the engine surfaces and in the lube system has been described through the erosion dynamics. The time-dependent concentration pattern related to hydrodynamic (sub)layers around the tar deposit has been uncovered. Nonlinear equations explaining the experimentally observed dependences for scouring the contaminants off with the oil have been derived and indicate the power law in time. For reference purposes, a similar analysis based on formal chemical kinetics has been accomplished. Factors and scouring parameters for the favor of either mechanism have been discussed. Any preference for either diffusion or chemical kinetics should be based on a careful selection of washing agents in the flushing oil. Future directions of studies are proposed.<\/jats:p>","DOI":"10.3390\/computation11080164","type":"journal-article","created":{"date-parts":[[2023,8,21]],"date-time":"2023-08-21T01:33:11Z","timestamp":1692581591000},"page":"164","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Diffusion Kinetics Theory of Removal of Assemblies\u2019 Surface Deposits with Flushing Oil"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6019-6904","authenticated-orcid":false,"given":"Michael","family":"Vigdorowitsch","sequence":"first","affiliation":[{"name":"Angara GmbH, M\u00f6rsenbroicher Weg 191, 40470 D\u00fcsseldorf, Germany"},{"name":"All-Russian Scientific Research Institute for the Use of Machinery and Oil Products in Agriculture, Novo-Rubezhnyy Sidestr. 28, 392022 Tambov, Russia"}]},{"given":"Valery V.","family":"Ostrikov","sequence":"additional","affiliation":[{"name":"All-Russian Scientific Research Institute for the Use of Machinery and Oil Products in Agriculture, Novo-Rubezhnyy Sidestr. 28, 392022 Tambov, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4136-1227","authenticated-orcid":false,"given":"Alexander N.","family":"Pchelintsev","sequence":"additional","affiliation":[{"name":"Department of Higher Mathematics, Tambov State Technical University, Sovetskaya Str. 106, 392000 Tambov, Russia"}]},{"given":"Irina Yu.","family":"Pchelintseva","sequence":"additional","affiliation":[{"name":"Department of Automated Decision Support Systems, Tambov State Technical University, Sovetskaya Str. 106, 392000 Tambov, Russia"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"116496","DOI":"10.1016\/j.enconman.2022.116496","article-title":"A comprehensive review of primary strategies for tar removal in biomass gasification","volume":"276","author":"Cortazar","year":"2023","journal-title":"Energy Convers.
