(Prior Art) Conventionally, a compressor has been equipped with a turbine placed in the exhaust system and driven by the exhaust gas flow, and a compressor placed in the intake system and connected to the turbine via a rotating shaft to supercharge the intake air. Turbo superchargers are known. When installing this turbocharger, it is necessary to reliably prevent leakage of exhaust gas, so normally, the turbine housing of the turbocharger is fixedly connected to the exhaust manifold with a pin etc. An exhaust pipe was fixedly connected to the turbine housing so that the exhaust pipe was supported by the turbine housing. However, with this structure, multiple exhaust pipes are applied to the turbine housing, so there is a risk that deformation of the turbine housing will cause the turbine to become stuck on its inner surface, causing it to stop rotating or being damaged.

Therefore, since the load of the exhaust pipe is often applied to the turbine housing, it is considered that the exhaust pipe is supported by the engine body or the vehicle body via a support member. However, in this case, the exhaust pipe side end of the turbine housing is restrained, so when the exhaust manifold presses due to temperature, stress due to thermal expansion acts on the turbine housing, which can cause turbocharger failure or damage. There still remains the problem that it is more likely to occur.

In addition, as seen in Japanese Utility Model Application Publication No. 57-117716, vibrations can be reduced by connecting bellows-shaped flexible piping between the exhaust manifold and the turbine housing, and between the turbine housing and the exhaust pipe. Some attempt to absorb thermal expansion. However, the above-mentioned flexible piping is expensive, and has the disadvantage that it is easily cracked by vibration and has poor durability.

The support leg 14 is preferably formed of a pipe, and is integrally connected to the exhaust manifold 3 and the upstream end portion 12a of the exhaust pipe 12, so that the exhaust manifold 3 and the exhaust pipe 12 support the support leg 14. Please make sure to communicate through it.

In this exhaust system, since the exhaust pipe 12 is supported by the support legs 14, the load of the exhaust pipe 12 is not applied to the turbine housing 5 of the turbocharger 114. Further, when the exhaust manifold 3 thermally expands due to a rise in exhaust gas am during high negative operation, the entire turbine housing 5 connected to the gathering portion 3a is pushed and the support 1114 moves. Therefore, the connecting portion of the exhaust pipe 12 to the turbine housing 5 is also displaced. Therefore, stress due to thermal expansion is significantly reduced compared to the case where the support legs are fixed to the vehicle body or cylinder block. In particular, as described above, if the support leg 14 is formed into a pipe shape that communicates with the exhaust manifold 3 and the exhaust pipe 12 and is integrally connected to these, the exhaust pipe 12 can be supported robustly, and the exhaust manifold 3 thermally expands, the high-temperature exhaust gas also flows to the support leg 14.
3 also undergoes thermal expansion. Therefore, by appropriately setting the passage area of the support leg 14 in advance, the displacement of the upstream end and the downstream end of the turbine housing 5 during thermal expansion can be matched, and the stress due to thermal expansion can be reduced. can be prevented from being applied to the turbine housing 5.

(Effects of the Invention) As described above, the present invention connects an exhaust pipe to a turbine housing connected to an exhaust manifold, and connects this exhaust pipe to a turbine housing connected to an exhaust manifold.
Because it is supported by support legs fixed to the exhaust manifold, it prevents the load of the exhaust pipe from being applied to the turbine housing, and also prevents stress due to thermal expansion of the exhaust manifold from acting on the turbine housing. Therefore, failure and damage to the turbocharger can be prevented, and the structure is in a cylinder and is more durable than that shown in the above-mentioned Japanese Utility Model Publication No. 57-117716.
