A turbine housing for a high-pressure turbo-charger of a turbo-charger engine system for an internal combustion engine is provided that includes, but is not limited to a low-pressure charger opening for taking up a low-pressure turbo-charger and a high-pressure charger opening for taking up a high-pressure turbo-charger. A high-pressure exhaust opening is attached to a corresponding flange at an exhaust manifold of the engine and there is a short-cut exhaust opening with a high-pressure turbine by-pass valve area attached to a corresponding flange at the exhaust manifold. An external connection opening is attached to a muffler, a waste gate valve area being provided in the close vicinity of the external connection opening.

Two-stage turbo-charger engine system

Arrangement of a two stage turbocharger system for an internal combustion engine including an intake manifold and an exhaust manifold, including a low-pressure turbocharger, a high-pressure turbocharger and a bypass duct in flow communication with an outlet of the low-pressure compressor, an inlet of the high-pressure compressor, an outlet of the high-pressure compressor and an inlet of the intake manifold. The bypass duct includes a first bypass valve for opening and closing the bypass duct. The first bypass valve and the high-pressure compressor are accommodated within a common housing.

Arrangement of a two stage turbocharger system for an internal combustion engine

The invention relates to a reciprocating engine in a motor vehicle, comprising a coupling arrangement for transmission of a torque, from a crank shaft end, to a crank shaft flange supported in a cylinder block, the crank shaft end being movable in the radial direction with respect to the crank shaft flange, characterised in that the crank shaft end and the crank shaft flange together form an axially extended cavity adapted to contain the coupling arrangement.

Reciprocating engine

Internal combustion engine with variable compression, comprising a crankshaft-bearing crankcase part and a cylinder-receiving part arranged tiltably thereon by means of a tilt axle bearing on one side of the engine and a tilt mechanism on the other, opposite side of the engine. The cylinder-receiving part supports a cylinder head which is securely connected thereto, preferably with camshafts mounted therein. There are prestressing members arranged between the crankcase part and the cylinder-receiving part which force these engine parts apart and work to counteract the occurrence of bearing play in the tilt axle bearing and in the tilt mechanism when compression-modifying tilting movement between the cylinder-receiving part and the crankcase part occurs during running of the engine.
