A device for converting a rectilinear movement into a rotary movement, comprising at least one piston-cylinder mechanism having a cylinder and a piston moveable arranged in the cylinder for rectilinear movement, a crankshaft for rotary movement, and a connecting rod connecting the piston and the crankshaft, the centre of rotation of the crankshaft being arranged displaced at a distance from the line along which the piston is moveable and that the crankshaft has a direction of rotation so that the part of the crankshaft which in relation to the movement line of the piston is located on the other side of the centre of rotation of the crank shaft, looked at the device in the longitudinal direction of the crankshaft has a movement component which is parallel with the movement line of the piston and directed away from the cylinder.
A device for converting a rectilinear movement into a rotary movement, said device comprising a crankshaft and one or more piston-cylinder mechanisms, each piston cylinder mechanism having a cylinder, a piston and a connecting rod connecting the piston to the crankshaft such that said piston is moveably arranged in the cylinder for rectilinear movement along an axis of movement to cause said crankshaft to effect said rotary movement, wherein the crankshaft has a center of rotation which is arranged displaced at a displacement distance of greater than or equal to 0.01 multiplied by the length of the piston stroke from the axis of movement of the or each piston and that the crankshaft has a direction of rotation that is clockwise when looking at the device in the longitudinal direction of the crankshaft and with the device oriented so that the or each cylinder is located above the crankshaft and displacement of the center of rotation of the crankshaft is to the right of the axis of movement of the or each piston, wherein improved torque is provided in an early portion of the cycle after top dead center for higher performance.
