AXIAL-PISTON COMBINED INTERNAL COMBUSTION ENGINE Russian patent published in 1994 - IPC

FIELD: engine engineering. SUBSTANCE: engine has case, cylinder bank, piston, and output shaft. Axes of the cylinders are parallel to the shaft and arranged over a periphery which is coaxial and parallel to the shaft. The pistons form working and under-piston spaces. Rods of the pistons are provided with pins at their ends and are perpendicular to the pins. The pins are in contact with a curved guide of the shaft by their ones ends and with straight guide of the case by their other ends. Delivery and expanding machines are coupled with the shaft. The expanding machine is made of an axial turbine positioned within a bushing, which is provided with a curved guide, and coupled with the shaft through a planet reduction gear. Exhaust gases and air from the under-piston space act on the turbine. The case, cylinders, pistons, bushing, and vanes of the turbine are made of monocrystal of leucosapphire. The working cylinders are provided with nozzles. EFFECT: enhanced efficiency. 16 cl, 4 dwg
