METHOD OF OPERATION OF INTERNAL COMBUSTION ENGINE AND INTERNAL COMBUSTION ENGINE IMPLEMENTATION THE METHOD Russian patent published in 2005 - IPC

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: according to proposed method of operation of internal combustion engine, by intake of compressed air, its compression, injection and combustion of fuel and exhaust of waste gases and delivery of additional working medium at transient conditions, compression ratio of air at transient conditions is increased by turning rotor of turbocompressor, and at transient starting and keeping of engine at hot stand-by mode, engine is warmed before delivery of fuel and compressed air into cylinders. Rotor of turbocompressor is turned at transient conditions by steam formed by heat of exhaust gases in heat exchanger installed at engine outlet and by additional working medium received by combustion of mixture of air from air space and exhaust gases of engine at engine outlet before heat exchanger. Crankshaft of engine at transient conditions and operation at overload is turned up by electric machine supplied by storage battery through frequency and voltage converter. Used as additional working medium supplied to intake of engine, compressed air from reservoir is used with replenishment of air by electric compressor. Additional working medium-heat carrier is introduced into exhaust gases of engine at transient conditions and at operation at low load. Said heat carrier is prepared by combustion of mixture of fuel delivered under pressure from reservoir at engine outlet before heat exchanger, and mixture of air from air space and exhaust gases of engine. Storage batteries are trickle-charged by thermoelectric generator built into heat exchanger, and their charging is carried out when engine operates at low loads by electric machine through frequency and voltage converter. Delivery of energy from frequency and voltage converter to all consumers and delivery of steam from heat exchanger are provided under all operating conditions.

EFFECT: improved efficiency of engine operation under static and transient conditions, power and heat supply of consumers, dynamic characteristics of turbocompressor.
