Abstract
A split-cycle internal combustion engine is disclosed. The engine includes a cylinder block, and a plurality of cooperating power pistons and cylinders mounted in the cylinder block. The power pistons are configured to be energized by forces of combustion. The engine also includes a compressor piston and cylinder configured to compress a volume of air and transfer the compressed air to the power pistons, and an expander piston and cylinder configured to receive exhaust gases from the power pistons. The engine additionally includes a first crankshaft operatively connected to and rotatably driven by the power pistons, a second crankshaft operatively connected to the compressor piston and configured to rotatably drive the compressor piston, and a third crankshaft operatively connected to the expander piston and configured to be rotatably driven by the expander piston. The first, second, and third crankshafts are operatively connected to each other for coordinated rotation.
