Abstract: An insulated exhaust port liner of a cylinder head assembly for fluidly connecting to an internal combustion engine of a motor vehicle includes a sealing layer. The sealing layer has a first surface defining a passage for fluidly connecting to the internal combustion engine and receiving exhaust gas. The sealing layer further includes a second surface opposite to the first surface. The liner further includes a thermal barrier layer coated onto the second surface of the sealing layer. The thermal barrier layer is a porous non-woven material for supporting the sealing layer on the cylinder head and reducing a transfer of heat from the sealing layer to the cylinder head.

Abstract: An electric drive unit is provided having an electric motor-generator coupled with a torque converter. Vehicles and machines employing the same, as well as methods of using the same, are also disclosed. The motor-generator may be configured to selectively drive a rotatable shaft with a motor output torque and generate electrical power from rotation of the rotatable shaft. The electric drive unit may further include a torque converter having an input and an output separated by a fluid coupling. The fluid coupling may be configured to selectively multiply torque received at the input such that a drive unit output torque at the output is selectively increased in at least a predetermined rotational speed range of the electric motor-generator.

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.
