れにより全体を大型化させていた。 Conventionally, as shown in FIGS. 1 and 2, for example, exhaust gas from each cylinder 2 of an internal combustion engine 1 is routed through exhaust gas exhaust pipes from the cylinders 2 to avoid thermal stress effects caused by high-temperature exhaust gas and to improve scavenging and exhaust efficiency. 3. The exhaust gas was collected in the exhaust gas collecting pipe 6 via a telescopic pipe 4 attached to the exhaust gas discharge pipe 3 and a diffuser 5 attached to the telescopic pipe 4. 7 is a protection tube. According to this, since the telescopic pipe 4 and the diff user 5 are arranged in a straight line, the distance L between the discharge end of the exhaust gas discharge pipe 3 and the center of the exhaust gas collecting pipe 6 becomes large, which increases the overall size. was.

化できる。 That is, in the present invention, the expansion side of the diff user attached to the exhaust gas exhaust pipe is located within the exhaust gas collecting pipe,
The present invention proposes an exhaust gas coupling device in which a telescopic pipe is provided between the pipe expanding side of the diff user and the exhaust gas collecting pipe. According to this configuration, since the diff user and the telescopic pipe are of a double pipe type, the exhaust gas collecting pipe can be brought sufficiently close to the exhaust gas discharge pipe, the width can be shortened, and the whole can be made compact.

離を示す。 An embodiment of the present invention will be described below with reference to FIG. 10 is an exhaust gas discharge pipe from the cylinder 11, and a diffuser 12 is attached to the tip thereof. The expanded pipe side of the diff user 12 is located within the exhaust gas collecting pipe 13. Said differential user 12
A protection tube 14 is fitted onto the outside, and this protection tube 14 is fixed to the exhaust gas collecting pipe 13. Here, protection tube 14
is formed to be shorter than the differential user 12.
15 is a telescopic tube, the inner end of which is connected to the diff user 1.
It is welded and fixed 16 to the outer periphery of the tube expansion side of the protection tube 14, and its outer end is welded and fixed 18 to a flange plate 17 attached to the outer end of the protection tube 14. l is exhaust gas discharge pipe 1
The distance between the discharge end of 0 and the center of the exhaust gas collecting pipe 13 is shown.
