PERFECTION OF WANKEL ENGINE AND SIMILAR ROTARY ENGINES Russian patent published in 2013 - IPC F02B53/04 F02B53/08 F02B55/14 F01C1/22 F01C1/18 F01C19/04 

FIELD: engines and pumps.

SUBSTANCE: proposed engine comprises, at least, one rotor, rotor housing with inlet and outlet, and rotor top seals. Besides, engine is furnished with two buffer seals arranged at two ends of rotor housing smaller axis to divide said housing in two chambers. First of the latter is suction and compression chamber. Second one represents expansion and exhaust chamber. Engine incorporates, at least, one flow control device. Said device is equipped with rotary combustion chamber (RCC) timed with rotor to force compressed fluid from first chamber via RCC inlet for fuel-air mix ignition and complete combustion before it enters RCC outlet to allow expansion of combustion products in second chamber. RCC allows control over compression ratio. Engine incorporates fuel injector to force fuel in appropriate RCC. Rotor is designed to create pressure for compression ignition and features factor K (rotor radius-to-offset ratio) equal to 4 that does not affect compression ratio. Every seal of rotor top stays in contact with buffer seals to slide thereon to allow constant contact with rotor outline.

EFFECT: higher efficiency of engine.
