AIR COOLED ROTARY PISTON INTERNAL COMBUSTION ENGINE Russian patent published in 2003 - IPC

FIELD: mechanical engineering; transport. SUBSTANCE: invention can be used as power units of vehicles. Said air cooled rotary piston engine contains rotary cylinder block, electronic ignition system, fuel and air feed system, housing, ring with bosses over perimeter, two additional bosses, synchronization eccentrics whose upper part is fitted in additional bosses and lower part, in lower cover of cylinder block. Exhaust gas system consists of exhaust manifold, port and pipe for exhaust gases. Pistons are connected by connecting rods with ring by means of pins fitted in ring bosses. Exhaust manifold is made in form of turbine consisting of ring chute located on rotary cylinder block and fixed sector made in form of part of fixed chute holes and blades between holes. Holes communicate with common pipe for exhaust gases, and ring chute is installed for displacement relative to part of fixed chute. Fuel feed system is made in form of priming electric pump, electromagnetic nozzles in number equal to number of cylinders, fuel channels made in cylinder block and fuel pipeline passing through axis of rotation of engine and installed for combined rotation with cylinder block. Inlets of fuel channels communicate through distributing space with fuel pipeline, and outlets of channels, with electromagnetic nozzles. EFFECT: reduced fuel consumption, increased power output and improved ecological characteristics. 7 dwg
