Abstract: This Rotary engine with pistons, a stator and a power chamber is comprising a Stator, which contains the power chamber for combusting a mixture of fuel and air; an air intake slot, exhaust slots and the power chamber located along an inside periphery of stator; a Rotor containing three of said pistons and three cylinders that create compression of the mixture of fuel and air; and an Eccentric Shaft for attachment to said pistons, said eccentric shaft moving said pistons in a inwardly and outwardly direction; the rotor further containing three pallets, which create a movable wall at an outer circumferential periphery of the rotor, said walls slide into the power chamber cavity of the stator; the rotor block has three equally spaced slots for mounting the three pallets, the Pallets, moves into the power chamber cavity during ignition of the compressed fuel and air mixture to enable the pallets and rotor to be pushed along the power chamber cavity, creating the rotation of the rotor.
