TEST STAND FOR INTERNAL COMBUSTION ENGINE TURBOCOMPRESSOR Russian patent published in 2004 - IPC

FIELD: testing technology; testing supercharging turbocompressors of internal combustion engines.

SUBSTANCE: proposed test stand includes inlet and outlet lines which are connected with turbocompressor under test, adjustable source of gas flow in form of technological compressor with adjustable drive, adjustable heater, first and second recuperative heat exchangers, adjustable interceptor, heat exchanger-cooler, measuring and control units; test stand is provided with technological turbocompressor with adjustable drive; inlet of its compressor is communicated with outlet of second loop of heat exchanger-cooler through controllable gate valve and outlet of compressor is connected with inlet of first loop of first recuperative heat exchanger by means of pipe line; outlet of first recuperative heat exchanger is connected with turbine inlet of technological turbocompressor; outlet of turbine of technological turbocompressor is communicated with second loop of heat exchanger-cooler.

EFFECT: reduced power requirements due to recuperation of heat and reduction of air pressure in test stand lines.
