COMBINED ENGINE AND METHOD OF ITS OPERATION Russian patent published in 1997 - IPC

FIELD: engine engineering. SUBSTANCE: combustion stroke of the engine is performed at a constant volume. Fuel is burnt out when the pistons are in the bottom dead centers after filling the cylinders with air by the use of a compressor. There is no compression in the cylinders and they rather serves for defining a closed space. The rod of the pistons is provided with jaws the bearing of which are provided with rollers which are in a contact with the cams of the shaft of the gas distributing disk. There are slides on both sides of the rollers on the jaw bearings in the groove of the housing. The reduction gear is interposed between the shaft of the gas distributing disk and the shaft of the turbine compressor. When seals are provided between the end faces of the cylinders and gas distributing disk gas flow rate is a minimum as the air inside the cylinders of the engine is not compressed. At the end of the exhaust stroke the spaces of exhaust gases of the gas distributing disk and path of the gas turbines are blown with air. EFFECT: enhanced efficiency. 3 cl, 7 dwg
