Definitions
- the invention relates to an exhaust system for a multi-cylinder internal combustion engine of a motor vehicle comprising a cylinder head of said engine in which exhaust pipes are arranged, a first end of each of which is connected to a combustion chamber of said engine. and whose second end opens into a cavity or plenum of an exhaust manifold integrated in the cylinder head, an outlet pipe is connected externally to a device for cleaning the exhaust gases of a vehicle exhaust line.
- the exhaust devices comprise exhaust ducts formed in the cylinder head of the engine which coincide with collector ducts arranged opposite the exhaust ducts.
- the collector comprises at least one outlet duct which is connected to an exhaust line of the motor vehicle.
- Document DE-A-3.81 5.408 describes a collector integrally formed in the breech and coming from a foundry therewith.
- the invention proposes a device of the type described above comprising a collector integrated in the cylinder head of the motor and mu and thermal decoupling means with respect to said cu lasse.
- the invention proposes a collector of the type described above, characterized in that characterized in that the cavity or plenum of the collector is formed in an element attached to the lower part of the yoke and that said The element is thermally decoupled from the battery by the intermediary of thermal decoupling means.
- the second ends of the exhaust ducts open into a receiving bore formed in the casing which receives a tubular insert which is attached to the inside of the bowl to form the insert, which comprises com munication ports with the second ends of the exhaust ducts, and which has the outlet duct opening out to the outside of the cu lasse.
- the tubular insert is made of stainless steel, the tubular insert is mounted without clearance in the receiving bore of the casing,
- the thermal decoupling means are arranged in the cylinder head around the tubular section and at least between two consecutive exhaust ducts; the thermal decoupling means comprise at least one cavity which is formed in the material of the cu lasse around the receiving bore and which opens into said bore, the device comprises a cavity which is arranged around the receiving bore between each pair of consecutive exhaust pipes, and a cavity which is arranged around the receiving bore between an end exhaust pipe and a outer end face of the bolt,
- FIG. 1 shows a cylinder head 10 for an exhaust device produced according to the invention.
- exhaust ducts 1 2 are arranged in the cylinder head 10.
- a first end 14 of each duct 1 2 is connected to a combustion chamber 1 6 of the engine and the second end 1 8 of each duct 12 opens into a cavity 20 or plenum of an exhaust manifold 22 integrated with the cylinder head 10.
- An outlet pipe 24 of the manifold 22 is connected externally to a device (not shown) for cleaning up the exhaust gases of a line of exhaust (not shown) of the vehicle.
- the cylinder head 10 comprises between each combustion chamber 16 cavities 30 for circulating a coolant of the engine.
- the cavity 20 or plenum m collector 22 is formed in an element 26 which is attached to the inside of the cylinder head 10 and said element 26 is thermally decoupled from the cylinder head 1 0 via means 28 for thermal decoupling. More particularly, the second ends 18 of the exhaust ducts 1 2 open into a receiving bore 32 which is formed in the tub 10, and this bore 32 receives a tubular insert 26 forming the attached element 26. which is attached to the inside of the cu lasse, which has orifices 34 communication with the second ends 1 8 exhaust ducts 12, and which has the outlet conduit 24 opening out of the cylinder head 1 0.
- the tubular insert 26 is made of stainless steel, because this material has thermal expansion characteristics to ensure a satisfactory seal when connected to the depollution device, regardless of its temperature. It should be noted that this characteristic is not limiting of the invention, and that any other material having similar characteristics could be used for the proper implementation of the invention.
- the tubular insert 26 is mounted without play in the bore 32 for receiving the cylinder head 10.
- the tubular insert 26 is for example fitted into the bore 32 according to a type adjustment tight.
- the thermal decoupling means 28 are arranged in the cylinder head around the tubular insert 26 and at least between two consecutive exhaust ducts 12.
- the thermal decoupling means 28 comprise at least one cavity 28 which is formed in the material of the yoke 10 around the receiving bore 32, and which opens into said bore 32. This cavity is filled with air and thus allows a thermal decoupling of the insert 26 with respect to the cylinder head, avoiding that the heat of the cylinder head 1 0 is communicated to the insert 26 by conduction.
- the device comprises a cavity 28 which is arranged around the receiving bore 32 between each pair of consecutive exhaust pipes 1 2, and a cavity 28 which is arranged around the receiving bore 32 between an end exhaust pipe 12 and an end outer face 36 of the cylinder head 10.
- each cavity 28 is made during the molding of the cylinder head 10.
- the invention therefore makes it possible to benefit from a device comprising a manifold 26 attached to the cylinder head 1 0 as close as possible to the combustion chambers 12, which makes it possible to optimize the performance of a pollution control device connected to its outlet duct. 24, and which is free from the disadvantages of integrated collectors known from the state of the art due to its thermal decoupling vis-à-vis the cylinder head 10.
