METHOD OF FLUSHING CYLINDERS DURING PRESERVATION OF INTERNAL COMBUSTION ENGINES Russian patent published in 2024 - IPC B65D85/68 F02B77/04 

FIELD: vehicles; methods and devices for vehicle maintenance.

SUBSTANCE: invention relates to maintenance of motor transport equipment at the stage of its preparation for storage and can be used for performance of the main operation of internal combustion engines preservation—washing of cylinders. Disclosed is a method for flushing cylinders during preservation of the engine, which consists in the fact that the engine is started and warmed up and two oil residues are sequentially pumped from the gearbox, the engine is stopped, turning on the engine starter to crank the engine crankshaft and after 0.5 s after the start of operation of the starter, oil is supplied to the engine cylinders for 4 s through the oil pump and after it is turned off after 0.5 s the starter is turned off, which means the end of the first oil filling into the engine cylinders. Similarly, second and third oil filling is carried out into engine cylinders with breaks of 15 s, after the third oil filling, after pause of 15 s, the starter is switched on for 5 s to crank the engine crankshaft without oil supply, whereupon the engine cylinder washing cycle is completed.

EFFECT: higher quality and efficiency of cylinder flushing during engine preservation.
