ROTARY INTERNAL COMBUSTION ENGINE Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention relates to divided cycle rotary internal combustion engines. Proposed engine contains compression and expansion sections including stator, outer and inner eccentric rotors synchronized in rpms, dividing plates hinge-rested on outer rotor and freely fitted in slots of hinge of inner rotor to form working chambers, and also end face walls of outer rotor with timing ports and shaft. According to invention, sections are installed in succession on common shaft to form common unit with common stator and common outer rotor. Dividing plates of second machine lag relative to dividing plates of first machine in angle of shaft turning by 22-24^o. Timing disk with scavenging ports and compressed air delivery channels is installed on outer rotor between two inner rotors. EFFECT: increased thermal efficiency of engine. 2 cl, 2 dwg
