TEST BENCH FOR ENGINE OILS FOR TWO-STROKE INTERNAL COMBUSTION ENGINES Russian patent published in 2024 - IPC G01N33/30 

FIELD: testing.

SUBSTANCE: invention relates to test benches for motor oils and can be used in research organizations, laboratories of oil refineries and in other organizations, which control the quality of motor oils for two-stroke internal combustion engines (ICE). Engine oil test bench for two-stroke ICE contains connected to electric brake 1 two-stroke ICE 2 with exhaust pipeline 6 for removal of exhaust gases, ICE 2 head temperature sensor 7 and ICE 2 air cooling system with fan 8 equipped with individual drive 9. To create and automatically maintain the optimal temperature mode of operation of ICE 2 and temperature of exhaust gases in outlet pipeline 6 ICE bench is equipped with control unit 20, one output of which is connected to individual drive 9 of air cooling fan 8, and the second is with actuator 18 of valve 17 for controlling the supply of cooling liquid into the inner cavity of chamber 14, in which there is a section of ICE outlet pipeline 6.

EFFECT: wider temperature range for testing engine oils for two-stroke engines due to reduced inertia of the test bench engine temperature control process with simultaneous reduction of fire hazard of tests.
