Split-cycle air hybrid engine

摘要

An engine comprising:
a crankshaft (18) rotatable about a crankshaft axis;
a power piston (24) slidably received within a power cylinder (14) and operatively connected to the crankshaft such that the power piston (24) is operable to reciprocate through an expansion stroke and an exhaust stroke during a single rotation of the crankshaft and such that the ratio of the volume in the power cylinder (14) when the power piston (24) is at its bottom dead center (BDC) position to the volume in the power cylinder when the power piston is at its top dead center (TDC) position is 26 to 1 or greater;
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).
