DEVICE FOR TESTING EXHAUST SYSTEM OF INTERNAL COMBUSTION ENGINE Russian patent published in 1994 - IPC

FIELD: automotive engineering. SUBSTANCE: device comprises plate 1 carrying supports 2 with flexible members 3 linked kinematically with test engine 4 and its exhaust system 5. Vibration generator 7 is mounted on engine 4. Burner 8 is connected to engine exhaust pipe. Connecting unit 12 is installed between burner outlet pipe 10 and engine exhaust system. During the tests the vibration exciter transmits vibrations to engine 4, its exhaust system 5 and connecting unit 12. Vibrations exert no effect on body of burner 8 since pipe 14 has no rigid connection with pipeline 16 and the latter is connected to burner body 8 by movable joint. Engine and its exhaust system can vibrate and be deformed without exerting any influence on burner 8. Hot gases are supplied into engine exhaust system by burner 8. EFFECT: higher functional and operating characteristics. 5 cl, 2 dwg
