DEVICE FOR IN-PLACE CLEANING PARTS OF INTERNAL COMBUSTION ENGINE FROM SCALE Russian patent published in 2019 - IPC F02B77/04 

FIELD: engine building.

SUBSTANCE: invention relates to maintenance of internal combustion engines (ICE) for various purposes, in particular, to cleaning of parts of cylinder-piston group from scale, due to incomplete combustion of fuel, and can be used for recovery of engine operating parameters. Peculiar feature of the invention consists in the fact that the device for the cleaning of the internal combustion engine parts is additionally equipped with a tank equipped with a despirgator for mixing two mutually insoluble liquids, having an inlet nozzle with a liquid level limiter and an outlet nozzle with a check valve, mixer with two inlet nozzles, the first input of which is connected through a two-channel controlled valve to the fuel supply channel, and the second inlet is connected to the service fluid supply channel, mixer output is connected to tank inlet nozzle, control unit, which input is technical, and first output of which is connected to despirgator, and second outlet is connected to controlled valves of fuel and technical fluid supply.

EFFECT: this ensures engine operation in all its modes without its decommissioning and allows to prolong its service life, as well as to prevent formation of scale on the parts and, without consequences, with small particles, to remove it without using disassembly.
