Abstract
An internal combustion engine may comprise at least one double cylinder (). A piston () is reciprocally movably disposed in each individual cylinder () of the double cylinder and each piston is connected to a crankshaft (). The pistons preferably reciprocate in the same direction within the individual cylinders. A cylinder space () is defined within the cylinders above each piston head. Preferably, the cylinder spaces are formed such that the cylinder spaces communicate during at least a portion of the reciprocal movement of the pistons.
