ROTARY SUPERCHARGED INTERNAL COMBUSTION ENGINE Russian patent published in 1998 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: engine is furnished with supercharging system, inlet and outlet channels, housing with linear working surface accommodating rotor with piston. Engine is provided with scavenging system made in form of two channels coupled by manifold. Supercharging system is made in form of two channels one of which, the first one, is arranged in supercharging section on extension of smaller axis of housing linear surface and coupled with manifold and second channel arranged in compression sector. Inlet channel is located in suction sector and is furnished with gate. Linear working surface can be made in form of surface formed by movement of center of circumference along guide contour consisting of two semicircumferences conjugated through parallel straight lines and forming toroidal-cylindrical surface. Working surface can be made as surface formed by movement of center of circumference along guide-the Cassianian oval, or as surface formed by movement of center of circumference along ellipse. Center of rotor is displaced through value defined by mathematical expression. EFFECT: increased power and economy of engine. 6 dwg
