ELECTROMECHANICAL STAND TO RUN IN AND TEST INTERNAL COMBUSTION ENGINES Russian patent published in 1999 - IPC

FIELD: mechanical engineering. SUBSTANCE: electromechanical stand has differential gear transmission for each tested internal combustion engine. Their bearing shafts are connected to rotors of regulation asynchronous machines and their output shafts are linked via common shaft to load generator. Regulation asynchronous machines are connected to thyristor frequency converters which controlling inputs are linked to outputs of summing amplifiers. Inputs of amplifiers are connected to outputs of tachotransmitter and microprocessor which other outputs are connected to comparators whose outputs are linked via converters to internal combustion engines. EFFECT: provision for testing of several engines, generation of electric energy of stable parameters with slightly changing output power of load generator. 2 dwg
