Diffusion Kinetics Theory of Removal of Assemblies’ Surface Deposits with Flushing Oil

The diffusion kinetics theory of cleaning assemblies such as combustion engines with flushing oil has been introduced. Evolution tar deposits on the engine surfaces and in lube system described through erosion dynamics. time-dependent concentration pattern related to hydrodynamic (sub)layers around deposit uncovered. Nonlinear equations explaining experimentally observed dependences for scouring contaminants off have derived indicate power law time. For reference purposes, a similar analysis based formal chemical accomplished. Factors parameters favor either mechanism discussed. Any preference or should be careful selection washing agents oil. Future directions studies are proposed.
