Disclosed is a rotary piston engine which includes a cylinder body (1), a cylinder head (15), two sets of pistons (3A, 4B) and clutches(10, 42), wherein two sets of pistons (3A, 4B) are respectively arranged on the outer diameter of a base and a piston hub (63). The clutch includes a one-way overrun clutch mounted in the inner diameter of the piston hub and a controlled one-way overrun clutch mounted in the inner diameter of a hollow shaft (32) on the out side face of the piston hub. When any one set of pistons rotate, intake, compression, working and exhaust are carried out at the same time. The position of one set of pistons when its compression stoke is over is behind the other set of pistons at its combustion and expansion stokes so that the rotational inertial force of piston can be relieved. The rotary piston engine has a simple and compact structure and good sealing property can be enabled. |
