Abstract: An engine block assembly includes a head structure assembly, and a cylinder structure assembly. A plurality of fasteners interconnect the head structure assembly and the cylinder structure assembly. An outer shell encapsulates and supports both the head structure assembly and the cylinder structure assembly. The outer shell is a unitary polymer structure that is simultaneously over-molded onto the head structure assembly and the cylinder structure assembly. The head structure assembly and the cylinder structure assembly are constructed of components that are designed to carry the operational loads of the engine with minimal weight. The outer shell provides additional structural integrity, and provides fluid passages for lubrication and cooling, as well as support for other engine components.

Abstract: A cylinder liner assembly includes an inner wear cylinder, a shell disposed radially outside of an outer surface of the inner wear cylinder, and a central layer disposed between the inner wear cylinder and the shell. The inner wear cylinder is a metal or ceramic, the central layer is a porous material, and the shell is a fiber reinforced polymer. The cylinder liner assembly may include a coolant passage disposed adjacent to the outer surface of the inner wear cylinder, between the inner wear cylinder and the shell. The coolant passage is operable to circulate a coolant therethrough for cooling the inner wear cylinder.

Abstract: A piston compound internal combustion engine is disclosed with an expander piston deactivation feature. A piston internal combustion engine is compounded with a secondary expander piston, where the expander piston extracts energy from the exhaust gases being expelled from the primary power pistons. The secondary expander piston can be deactivated and immobilized, or its stroke can be reduced, under low load conditions in order to reduce parasitic losses and over-expansion. Two mechanizations are disclosed for the secondary expander piston's coupling with the power pistons and crankshaft. Control strategies for activation and deactivation of the secondary expander piston are also disclosed.

Abstract: A single-shaft dual expansion internal combustion engine includes an engine block, a cylinder head and a crankshaft. First and second power pistons are moveable in first and second power cylinders and are connected to first and second crankpins of the crankshaft. An expander piston is moveable in an expander cylinder and is connected via a multi-link connecting rod assembly to a third crankpin of the crankshaft. A first balance shaft is arranged in a first longitudinal opening in the engine block, and a second balance shaft is arranged in a second longitudinal opening in the engine block. The first and second balance shafts have first and second counterweight portions, respectively, and the crankshaft has a third counterweight portion causing an imbalance in the crankshaft.
