Abstract: An internal combustion engine, ICE, system, includes a turbocharger having a turbine and a compressor for compressing intake air and feeding the intake air to the ICE. A turbo turbine unit is disposed in an exhaust gas path downstream the turbocharger to receive exhaust gas from the turbocharger. The turbo turbine unit having a turbine wheel, a bearing housing defining an inside volume for containing lubrication oil, and a sealing arrangement positioned in the vicinity of the turbine wheel for preventing lubrication oil from escaping from the inside volume of the bearing housing to an exhaust duct of the turbo turbine unit. A buffer air conduit extends between a selected position at the compressor and a buffer air inlet of the turbo turbine unit.

Abstract: A clamp for connecting a first component end to a second component end is provided. The clamp includes a web extending between a first end and a second end, each end being provided with a connecting device for connecting said web ends to each other so that the clamp encloses the component ends. The clamp further includes an alignment structure, which alignment structure is configured to fit with corresponding engagement structures provided at the first component end and the second component end for circumferentially positioning the clamp relative to the component ends.

Abstract: An engine structure forming an adapter for connecting a turbocharger unit to a cylinder block of an internal combustion engine includes a set of attachment arrangements for fastening the turbocharger unit to the cylinder block via the engine structure such that the engine structure is positioned in between the turbocharger unit and the cylinder block. The engine structure includes at least one fluid channel extending in a bent manner from a first surface of the engine structure to a second surface of the engine structure.

Abstract: An engine arrangement includes a first engine unit, a second engine unit and at least one member for fastening the second engine unit to the first engine unit. The first unit and the second unit include fluid ports for achieving a fluid flow between the first and second unit. The engine arrangement further includes a valve for opening and closing at least one of the fluid ports and the fastening member is moveably arranged relative to the first unit and second unit and is arranged to act on the valve.

Abstract: A turbocompound unit for converting energy of an exhaust gas from an internal combustion engine to torque increase of a crankshaft of the internal combustion engine includes a turbine arrangement and an arrangement configured to operatively connecting the turbine arrangement to the crankshaft is a hydrodynamic coupling and freewheeling arrangement. The turbocompound unit further includes a brake arrangement, wherein the brake arrangement and the freewheeling arrangement are located on an opposite side of the hydrodynamic coupling in relation to the turbine arrangement.

Abstract: A turbine system for recovering energy of exhaust gases of an internal combustion engine is provided. The turbine system includes a first turbine device, a second turbine device, and a flow control valve for bypassing exhaust gases passed the second turbine device. The turbine system further includes a pneumatic valve arranged between the first turbine device and the second turbine device and being configured to control the flow of exhaust gas to the second turbine device.
