LASER HEAT ENGINE Russian patent published in 1999 - IPC

FIELD: power-plant engineering. SUBSTANCE: engine has cylinder block with crankcase accommodating crank gear, supply, cooling, lubricating, and starting systems, and electrical equipment. There is also laser system for heating working medium that has semiconductor heterolasers pumped with electron beam and using electrostatic scanning which are installed in cylinder head, one per cylinder, and connected through switching device to high-voltage unit and to current supply; it also has two distributing controllers kinematically linked with crankshaft and with system controlling working medium supply to cylinders and electrically connected to switching devices and to current supply, regenerating cyclone pneumatically coupled with intake and exhaust manifolds whose inner space communicates with atmosphere and drain tank, as well as pistons whose outer surfaces carry cermet plates. EFFECT: improved performance characteristics of heat engine. 6 cl, 17 dwg
