INTERNAL COMBUSTION ENGINE Russian patent published in 2007 - IPC F02D13/02 F16C7/02 F02B23/00 

FIELD: mechanical engineering; piston internal combustion engines.

SUBSTANCE: according to invention, proposed internal combustion engine includes cylinder with piston arranged in cylinder, cylinder cove, and camshaft and crankshaft. Crankshaft is made so that radius of surface of crankpin far from axis of crankshaft exceeds radius of surface of crankshaft cheeks far from the same axis. Part of crankpin in TDC is located in cut belt of cylinder. Connecting rod is furnished with slider one rubbing surface of which encloses part of crankpin of crankshaft, resting on said crankshaft, and other part fastened on connecting rod rests on inner surface of sleeve enclosing surfaces of all sliders resting on one crankpin. Device is installed in camshaft drive to control camshaft and crankshaft at their synchronous rotation providing displacement of angle of camshaft relative to angle of turning of crankshaft. Device is installed between camshaft and its drive to control operation of engine providing change of angle of camshaft turning relative to its drive, and, consequently, relative to crankshaft. Open shutoff device of intake channel directs flow of fresh charge getting into cylinder towards piston. Closed shutoff device, either of intake or exhaust channel, separates part of said channel forming chamber in which working medium enclosed in cylinder gets accumulated, when piston moves to top dead center, and it is combusted near top dead center.

EFFECT: provision of internal combustion engine featuring better performance characteristics and reduced mass and overall dimensions.
