Sealing gasket, for sealing the connection between an exhaust manifold and a turbine

#This application is a 35 U.S.C. § 371 national stage application of PCT International Application No. PCT/IB2017/001755 filed on Dec. 20, 2017, the disclosure and content of which is incorporated by reference herein in its entirety.

#The present invention concerns a sealing gasket, for sealing the connection between an exhaust manifold and a Turbine.

#In the truck industry, turbochargers are commonly used with Diesel cycle internal combustion engines. A turbocharger is a turbine-driven device that increases the efficiency and the power of an internal combustion engine by forcing extra air into the combustion chamber. Typically, a turbocharger is powered by a turbine driven by the hot exhaust gas of the engine.

#The invention will be better understood from reading the following description, given solely by way of two non-limiting examples and with reference to the appended drawings, which are schematic depictions, in which:

#FIG. 1 is a side view of a vehicle, in particular a truck tractor, comprising a gas exhaust manifold and a turbine;

#FIG. 2 is a perspective view of the turbine;

#FIG. 1 represents, in side view, a vehicle which is, in the example, a tractor truck 1. However, in a non-represented alternative embodiment, the vehicle may be different from a tractor truck. For instance, the vehicle may be a light, medium or heavy-duty vehicle, a utility vehicle, an autonomous vehicle, etc.

#The tractor truck 1 includes an internal combustion engine comprising an engine block (not represented) including a plurality of combustion cylinders, typically six cylinders.

#The engine further includes an exhaust gas manifold 4, represented on FIG. 3, which collects the gas exhausting from the combustion chambers of the engine cylinders. Typically, the exhaust gas manifold 4 includes six inlets 4.1, 4.2, 4.3, 4.4, 4.5 and 4.6 to be respectively connected to the combustion chambers of the engine. Exhaust gases coming from the first three cylinders, i.e. flowing in the inlets 4.1 to 4.3, are separated from exhaust gases coming from the three other cylinders, i.e. flowing in the inlets 4.4 to 4.6. Accordingly, the manifold 4 includes two gas flow channels 42 and 44 that open on a connecting flange 40 of the manifold 4. Both gas flow channels 42 and 44 are separated by a dividing wall 45 of the manifold 4. The dividing wall 45 extends up to the connecting flange 40.
