摘要： Engines and processes for their operation include a compressor cylinder, at least one power cylinder, and an expander cylinder. The outlet of the compressor cylinder is fed to the inlet of a power cylinder, and the outlet of the power cylinder is fed to the expander cylinder. The compressor cylinder and the expander cylinder are operated in two-stroke fashion, and the power cylinder is operated in four-stroke fashion, all of which cylinders share a common crankshaft. Heat may be recuperated from the exhaust gas and directed to the inlet gas of the power cylinder, increasing overall efficiency.

摘要： An internal combustion engine has four cylinders, each having a respective piston positioned therein and connected with a crankshaft for movement in the respective cylinder. Each cylinder has a plurality of ports with a plurality of valves openable and closable to control fluid flow into and out of the cylinder through the ports. Combustion occurs in a first two of the four cylinders (power cylinders) that are each interconnected between a second two of the four cylinders (inductor cylinders) via passages connecting ports of the respective cylinders. Opening and closing of the valves is timed to accomplish internal exhaust gas recirculation, i.e., such that fluid directed from the power cylinders to the inductor cylinders via the passages after combustion is redirected via the passages from the inductor cylinders to the power cylinders. A method of internal exhaust gas recirculation for an engine as described above is also provided.
