Carousel internal combustion engine

A spatially compact engine block assembly for an internal combustion engine, comprising:

• a substantially cylindrical engine block including:
• a first set of three or more cylinders each having a central vertical axis, the central vertical axes substantially parallel to one another, each of the three or more cylinders has a top piston and a bottom piston that opposes the top piston;
• a first set of three or more first crankshafts in an amount equal to an amount of the three or more cylinders, each of the first crankshafts connected to and configured to receive a linear motion generated by a bottom piston of one of the three or more cylinders and to rotate a first shaft, the three or more first crankshafts connected to a top end of the engine block;
• a first set of three or more first gears in an amount equal to an amount of the three or more first crankshafts and situated in a substantially polygonal relationship to one another, each of the first gears configured to be rotated by the shaft of one of the first crankshafts such that each one of the first crankshafts rotates a different one of the first gears;
• a lower central gear situated inward of, and in a beveled relationship with, each of the first gears such that the lower central gear rotates in a direction substantially perpendicular to a rotation of each of the first gears;
• a set of three or more second crankshafts in an amount equal to the three or more cylinders, each of the second crankshafts connected to and configured to receive a linear motion generated by a top piston of one of the three or more second cylinders and to rotate a second shaft, the three or more second crankshafts connected to a top end of the engine block;
• a set of three or more second gears in an amount equal to the three or more second crankshafts, each of the second gears configured to be rotated by the shaft of one of the second crankshafts such that each one of the second crankshafts rotates a different one of the second gears;
• and
• an upper central gear situated inward of, and in a beveled relationship with, each of the second gears such that the upper central gear rotates in a direction substantially perpendicular to a rotation of each of the second gears.
