TANK AUTONOMY IMPROVEMENT DEVICE Russian patent published in 2024 - IPC F02M35/08 F02M35/10 

FIELD: engines.

SUBSTANCE: invention can be used in air cleaning systems of internal combustion engines. Tank autonomy improvement device comprises air cleaner with its housing (11) accommodating cyclone (16) with its bottom connected with hopper (17) and with its top connected with second cleaning stage cavity. Hopper (17) has dust removal pipeline (14) with valve (15). There is hollow boom (8) for connection with an air supply pipe and hollow boom (3) for connection to a pressure indicator connected to signalling lamp (23). Device comprises high-pressure pipeline (22) with nozzles, pipe (12) of variable cross-section of dust removal, and cover (4). Cavity of the second cleaning stage accommodates at least one cylindrical cartridge (9) tightly fixed in its cage (10) installed on bearings (6) and having blades (5) in the upper and lower parts of the outer side. On the axis of cage (10) there is ratchet (7) engaged with the retainer. Upper part of pipe (12) of variable cross-section of dust removal has a conical socket facing the inner side of cylindrical cartridge (9) and coaxial with the nozzles of high-pressure pipeline (22). Lower part of pipe (12) of variable cross-section of dust removal is closed by valve (13) and is located inside pipeline (14) for dust removal. Upper and lower nozzles of high-pressure pipeline (22) are located at the level and directed to the cage blades. High-pressure pipeline (22) is connected to the air system of the machine by a high-pressure line with two parallel lines. In one parallel line there is pneumatic valve (20) with hydraulic control from fuel system and with check valve (18). In the other line there is an electric pneumatic valve (21) controlled by electrically connected to it electric button and control unit (1), which in its turn is electrically connected to on-board network and pressure indicator (2).

EFFECT: reduced time for maintenance of air cleaner.
