An integrated linear generator system includes, for example, a generator assembly, a control system, a frame system, an exhaust system, an intake system, a cooling system, a bearing system, one or more auxiliary systems, or a combination thereof. The generator system is configured to generate power, as controlled by the control system. The generator assembly may include an opposed- and free-piston linear generator, configured to operate on a two-stroke cycle. The intake and exhaust systems are configured to provide reactants to and remove products from the generator assembly, respectively. The cooling system is configured to effect heat transfer, material temperature, or both, of components of the integrated linear generator system. The bearing system is configured to constrain the off-axis motion of translators of the generator assembly without applying significant friction forces. The frame system is configured to manage rigidity, flexibility, and alignment of components of the integrated linear generator system.

Systems and assemblies are provided for sealing an interface between a cylinder and a manifold corresponding to the cylinder. The cylinder comprises at least one port. A manifold interface is arranged adjacent to the at least one port. A seal is located inside of a circumferential pocket, wherein the circumferential pocket comprises at least a portion of the manifold interface. A spring is configured to preload the seal radially inward so that the seal stays in contact with the outer surface of the cylinder.
