Split-Cycle Engine

A split-cycle engine is a type of internal combustion engine that divides the four strokes of a conventional Otto-cycle engine across two paired cylinders instead of completing all four in a single cylinder. One cylinder is dedicated to intake and compression, while a separate cylinder handles power and exhaust, with compressed air transferred between the two cylinders before fuel is injected and combustion occurs. Dividing the functions this way lets each cylinder's geometry and timing be optimized for its own task rather than compromising between them, as a conventional engine cylinder that performs all four strokes must. Split-cycle designs date back to at least 1891, and modern implementations such as the Scuderi engine have continued to develop the concept.
