ROTARY ENGINE Russian patent published in 1999 - IPC

FIELD: mechanical engineering; automobiles, motorcycles, motor boats. SUBSTANCE: cylindrical rotor 5 is installed on eccentric shaft 3 with provision of constant contact with inner cylindrical space of engine housing 1 when rolling over the space. Rotor 5 in its movement comes into constant engagement with movable partitions 10 and 11 and it engages periodically with partition 12, thus forming chambers in which intake, compression, working stroke and exhaust stroke take place. Intake of fuel and air mixture and exhaust of exhaust gases are provided through intake hole 16 and exhaust hole 17. Two spark plugs are installed to improve ignition in combustion chamber 18. In process of engine operation intake and exhaust phases last over whole revolution of rotor simultaneously. Phase of working stroke lasts during half of time of revolution and compression phase lasts during the other half of revolution also when intake and exhaust phases exist. EFFECT: simplified design, increased service life, enhanced economy. 6 dwg
