摘要： The invention concerns a rotary piston engine (1) that includes at least two straight circular cylinders (7), which are parallel with each other and connected to each other along a longitudinal cylinder jacket opening. In the cylinders (7) pistons (2, 3) are arranged rotably journaled in the cylinders (7). A sealing rod (6) is arranged in said cylinder jacket opening and is displaceable across the pistons (2, 3) in sealing contact with mantle surfaces of these. The pistons (2, 3) have central circular cylindrical parts, which have smaller diameters than the cylinders (7) and two opposite protruding wings each, that radially outward define exterior piston mantle surfaces, substantially having the same diameter as the cylinders (7), and are arranged to slide closely along jackets (8) of the cylinders (7). In the cylinder jackets (8) there are pairs of exhaust and intake openings (10-13), which are opened and closed by flap valves (9a-9d) and lead to different working chambers. In a certain rotational position of the pistons (2, 3) together with the sealing rod (6) and an opposite cylinder jacket part (8) they form a combustion chamber in said cylinder jacket opening.

摘要： A rotary engine (10) includes an insert (34) in one of the walls (18) of an outer body (12), the insert (34) having a pilot subchamber (72) defined therein communicating with the internal cavity (20) of the engine. An ignition element extends in an element cavity (88) defined through the insert (34) adjacent the subchamber (72). A portion (86) of the element (84) is in communication with the subchamber (72) through a communication opening (64) defined in the insert (34) between the element cavity (88) and the subchamber (72). The communication opening (64) has a cross-section smaller than a corresponding cross-section of the portion (86) of the element (84).
