<p>The invention relates to a four-cycle internal combustion rotary engine to be used in the automotive industry. According to the invention, the engine comprises some pistons () arranged diametrically opposite, two on each crown, some crowns (), both of them entering a ring-shaped cylinder () from the inside part which is cut out and seals the ring-shaped cylinder (), a system of satellites () attached to a fly wheel () engaging between the two crowns () so as to allow the crowns () different rotation speeds and to even the power generation, the crowns () also engaging, in a zone (), some free-wheel mechanisms permitting the rotation of the crowns () in a single sense, while, in a zone (), the crowns () are provided with cams, in order for them to open and close some intake valves () and some outlet valves () and to initiate the ignition, depending on the position of the pistons (), the ignition point () and the inlet valve () being arranged diametrically opposite on the ring-shaped cylinder () and the outlet valve () being arranged at the back of the inlet valve () in the sense of rotation of the crowns (), the ignition of the fuel mixture taking place in the same time with the opening of the inlet and outlet valves (), which occurs simultaneously, where the contact between the pistons () and the ring-shaped cylinder () is sealed with six piston rings for each piston (), namely three rings at one end and three rings at the other end of the piston () of which one is a lubricating ring and two are combustion rings, the engine being sealed against the upper carter between some points () and against the lower carter between some other points (), for allowing thereby the engine to be lubricated and the pressure to accumulate therein, the compression losses caused by the play between the crowns () and the ring-shaped cylinder () being thus reduced and the waste gas emission being prevented.</p> |
