AUTOMATED SYSTEM FOR CLEANING EXHAUST GASES OF INTERNAL COMBUSTION ENGINES AS PART OF A BRAKE TEST BENCH Russian patent published in 2024 - IPC F02B79/00 F01N3/04 F01N9/00 

FIELD: testing.

SUBSTANCE: invention can be used in testing internal combustion engines on brake test benches. ICE exhaust gas cleaning system as part of a brake test bench comprises an exhaust gas cleaning system, including exhaust pipeline (1) for removal of exhaust gases from the engine, communicated with receiver (2), electronic control unit (3), to inputs of which sensors (4) and (5) of load and speed modes of engine operation are connected. In engine exhaust pipeline (1) directly before receiver (2) electromagnetic nozzle (6) is installed, which is hydraulically connected with electric pump (7) for supplying water from tank (8) of irrigation water source and with mechanical shutoff valve (9). Nozzle (6) is electrically connected through electronic control unit (3) equipped with electric signal duration and pause regulators (11) and (12), with DC power supply source (12) and engine load and speed mode sensors (4) and (5). As irrigation water solution of distilled water with addition of 1…2% of antifreeze by volume is used.

EFFECT: simplified design of the system and reduced opacity of exhaust gases.
