Abstract
Improvements in an internal combustion engine comprising an elongated stationary piston having an elongated double ended movable piston coaxially mounted thereon for reciprocation. Two stationary combustion cylinders reciprocably receive the opposite ends of the movable piston, respectively. A crankshaft is journaled for rotation in the stationary piston, the axis of the crankshaft coinciding substantially with a diameter of both pistons. A crank on the crankshaft is operatively connected by means of a connecting rod to the movable piston, the connection of the rod to the movable piston being on the diameter lying in a plane which includes the axis of the crankshaft.
