Abstract: An internal combustion engine having paired opposed power cylinders, and a lever system interconnecting the pistons of the opposed power cylinders with each other and with a crankshaft. The lever system for each pair of cylinders includes the piston rods of the two pistons, each being pivotally connected at one end to its respective piston and being pivotally connected together at their opposite ends and also to one end of a lever arm. The lever arm is connected intermediate its ends to the crankshaft, and its other end is guided to follow a linear path and acts as a moveable fulcrum for the lever system. A compressor driven in rotation by the crankshaft supplies air to the cylinders.

Abstract: A fuel composition, preferably for use in internal combustion engines, comprising a water-in-oil emulsion of (a) a hydrocarbon fuel, such as gasoline, diesel fuel or fuel oil; (b) water; (c) preferably a water-soluble alcohol; and (d) a novel combination of surface-active agents to provide a clear composition which is stable against phase separation over a wide range of temperatures.
