METHOD FOR RAISING ECONOMIC EFFICIENCY, POWER CAPACITY, AND POSITIVE POWER BALANCE IN ELECTRICAL- EQUIPMENT SYSTEM OF VEHICLE USING COMPOUND-TURBINE ENGINE

摘要

FIELD: power-plant mechanical engineering; power supply systems. SUBSTANCE: method involves expanding exhaust gases in turbocompressor turbine and in power turbine coupled with engine crankshaft and disconnected from the latter at partial loads and speeds with exhaust gases bypassing mentioned turbine; in the process, generator is driven by crankshaft; novelty is that exhaust gases are first expanded within turbocompressor turbine and then within power turbine bypassing the latter at partial loads and speeds in which case they are expanded within generator drive turbine; generator is disconnected in this case from crankshaft and driven by mentioned turbine through special reduction unit. EFFECT: improved economic efficiency and power capacity of engine as well as positive power balance in on-board supply mains. 1 dwg
