A split-cycle air hybrid engine (10) comprising:
a crankshaft (18) rotatable about a crankshaft axis (20);
a power piston slidably (24) received within a power cylinder (14) and operatively connected to the crankshaft such that the power piston reciprocates through an expansion stroke and an exhaust stroke during a single rotation of the crankshaft (18);
a compression piston (26) slidably received within a compression cylinder (16) and operatively connected to the crankshaft such that the compression piston (26) reciprocates through an intake stroke and a compression stroke during a single rotation of the crankshaft (18);
an air reservoir (36) operatively connected between the compression cylinder (16) and the power cylinder (14) and selectively operable to receive compressed air from the compression cylinder (16) and to deliver compressed air to the power cylinder (14) for use in transmitting power to the crankshaft during engine operation; and
valves (46,50,52,54) selectively controlling gas flow into and out of the compression and power cylinders and the air reservoir such that the engine is operable in a pre-compressed air power (PAP) mode. |
