FIELD: engines and pumps.
SUBSTANCE: invention relates to ICE servicing, particularly, to diagnostics of ICEs. Proposed method consists in measuring residual vacuum pressure Prv and engine compression Pc for, at least, one cylinder of tested ICE before and after decoking. Obtained values are compared. If said values differ not more than by 10% residual life is defined. For this, basic graphical dependence of variation of Prv upon Pc is plotted and as well as sleeve assembly consumed life curve associated therewith. Prv and Pc values measured in the last dry starting are plotted on said curve. Position of said plotted points relative to basic graphical plot is used to define residual life of sleeve assembly for at least one cylinder.
EFFECT: fast determination.
