This Demonstration shows a model of a Scuderi split-cycle engine compared with a conventional four-stroke engine. The principal design difference between the two engines is that the conventional Otto-cycle engine requires two revolutions of the crankshaft to perform the four strokes of the cycle, whereas the split-cycle engine divides these four strokes between its paired cylinders, performing both intake and compression in one and power and exhaust in the other. This allows for the completion of all four strokes in one revolution of the crankshaft. The revolutionary aspect of the Scuderi cycle is that it separates the high pressure strokes of compression and power. Furthermore, the split-cycle engine also transfers compressed air from the compression cylinder to the power cylinder, allowing for recovered braking energy to be stored as compressed air.
