FIELD: machine building.
SUBSTANCE: motor with ring cylinder consists of one cylinder with side covers, of 4-blades pistons and of force mechanism. Lociniate pistons are installed in cylinder and are fixed in pairs at 2-co-axial naves. Force mechanism consists of pin 2 levers, fixed on co-axial naves, of connected by levers 2 connecting rods and of crankshaft connected to links. Ratio of height of lociniate pistons to its width and to diametre of cylinder is equal to 1: 1.5 : 3. Ratio of levers length to middle radius of ring cylinder is equal to 2:1. Levers with connecting rods are located from one side of motor. Crankpins of crankshafts are unfolded for angle 180°.
EFFECT: reduction of fuel consumption, increasing of maximal power, reduction of overall dimension volume, mass and cost of manufacturing of motor.
