Opposed-piston compact engine with crankshafts rotating on a different plant to those of the cylinder axes

An opposed piston internal combustion engine comprising:

• at least two cylinders, each cylinder containing an intake piston and an exhaust piston arranged in opposite directions within a long axis of the cylinder and on opposite sides of the center of the long axis of the cylinder, and each cylinder comprising an inner wall defining the cylinder volume;
• wherein an upper surface of the piston heads of the two pistons in each cylinder create, in combination with the cylinder wall, a combustion chamber for igniting and burning of fuel, and
• wherein each cylinder comprises, independently, at least one intake port on an intake half of the cylinder and at least one exhaust port on an exhaust half of the cylinder, each port disposed as an opening in the cylinder wall;
• and
• at least two crankshafts;
• wherein a first crankshaft is attached to at least one intake piston, and a second crankshaft is attached to at least one exhaust piston;
• and
• wherein a plane that contains the cylinder long axes of at least one pair of cylinders is not perpendicular, nor parallel, nor coincident with a plane that contains the rotational axes of the first and second crankshafts.
