Air Supply for Components of a Split-Cycle Engine

A system for supplying compressed air to a component requiring a supply of compressed air, the system comprising:

• an engine, comprising:
• a crankshaft rotatable about a crankshaft axis;
• a compression piston slidably received within a compression cylinder and operatively connected to the crankshaft such that the compression piston is operable to reciprocate through an intake stroke and a compression stroke during a single rotation of the crankshaft;
• an expansion (power) piston slidably received within an expansion cylinder and operatively connected to the crankshaft such that the expansion piston is operable to reciprocate through an expansion stroke and an exhaust stroke during a single rotation of the crankshaft;
• a crossover passage interconnecting the compression and expansion cylinders, the crossover passage including a crossover compression (XovrC) valve and a crossover expansion (XovrE) valve operable to define a pressure chamber therebetween;
• an air processing system operable to process compressed air and supply processed, compressed air to the component;
• and
• an air input line connected directly between the crossover passage and the air processing system, the air input line operable to supply compressed air from the crossover passage to the air processing system.
