<p>A multiple crankshaft IC engine (50) which allows a relatively large number of relatively small combustion cylinders, having pistons (60) to drive a common output shaft (28) by crankshaft pinions (54) to yield a relatively high power-to-weight ratio. Engine clusters are formed by layers of these engines (50) arranged into clusters of eight or more and coupled together with further pinions about a further central gear to a single further output shaft. The engine (50) has perfect balance due to the disposition of the crankshafts (56) so that the movement of pistons (60) and their associated crankshafts (56) and connecting rods (58) generate reactionary forces that cancel each other out. The engine (50) also has a rotary intake valve in the form of ports in the output shaft (28) for communication with the pistons (60) as the output shaft (28) rotates.</p> |
