Abstract
An exhaust apparatus includes a chamber disposed below an engine, an inlet pipe guiding exhaust gas from an exhaust pipe to the chamber, a tail pipe discharging the exhaust gas from the chamber to an outside, a first partition wall partitioning an inside of the chamber to a pair of left and right spaces, and a second partition wall partitioning one of the left and right spaces to a pair of front and rear spaces. Another of the left and right spaces is a first expansion chamber into which the inlet pipe enters. A rear space of the front and rear spaces is a second expansion chamber disposed downstream of the first expansion chamber. A front space of the front and rear spaces is a third expansion chamber disposed downstream of the second expansion chamber, and the tail pipe enters into the front space.
Claims6
An exhaust apparatus configured to purify exhaust gas exhausted from an engine through an exhaust pipe, the exhaust apparatus comprising:
- a chamber disposed below the engine;
- an inlet pipe configured to guide exhaust gas from the exhaust pipe to the chamber;
- a tail pipe configured to discharge the exhaust gas from the chamber to an outside;
- a first partition wall partitioning an inside of the chamber to a pair of left and right spaces;
- and
- a second partition wall partitioning one of the pair of left and right spaces to a pair of front and rear spaces, wherein
- another of the pair of left and right spaces is defined as a first expansion chamber into which the inlet pipe enters,
- a rear space of the pair of front and rear spaces is defined as a second expansion chamber disposed downstream of the first expansion chamber,
- a front space of the pair of front and rear spaces is defined as a third expansion chamber disposed downstream of the second expansion chamber, and the tail pipe enters into the third expansion chamber,
- the exhaust apparatus includes:
- a first communication pipe extending in a left-right direction and penetrating the first partition wall;
- and
- a second communication pipe extending in a front-rear direction and penetrating the second partition wall,
- the first expansion chamber and the second expansion chamber communicate with each other through the first communication pipe,
- the second expansion chamber and the third expansion chamber communicate with each other through the second communication pipe, and
- the first communication pipe overlaps an inlet of the second communication pipe in a direction in which the second communication pipe extends.
