Abstract
A vehicle includes an internal combustion engine; an engine body at least partially located at a center in a vehicle width direction; a first chamber provided in an exhaust passage extending from the engine body; and a second chamber provided downstream of the first chamber in the exhaust passage, in which the first chamber and the second chamber are each located behind the engine body, and at least a part of the first chamber and at least a part of the second chamber overlap the engine body in a vehicle width direction and a height direction, respectively. This vehicle structure can contribute to downsizing of an exhaust system of an internal combustion engine in a vehicle including a vehicle frequently used to travel on an uneven ground.
Claims6
A vehicle that has an internal combustion engine, the vehicle comprising:
- an engine body at least partially located at a center in a vehicle width direction;
- and
- an exhaust system,
- the exhaust system comprising:
- branch pipe portions each extending from a corresponding cylinder of the engine body;
- a downstream common pipe portion where the branch pipe portions merge;
- a first exhaust pipe connected to a downstream side of the downstream common pipe portion;
- a first chamber provided to a downstream side of the first exhaust pipe in an exhaust passage;
- and
- a second chamber provided downstream of the first chamber in the exhaust passage;
- and
- a second exhaust pipe extending between the first chamber and the second chamber,
- wherein
- the first chamber has a larger diameter than those of the first and second exhaust pipes, and is located behind the engine body in a vehicle longitudinal direction,
- at least a part of the first chamber and at least a part of the second chamber overlapping the engine body in a vehicle width direction and a height direction, respectively,
- the first chamber being provided with an upstream connection portion to which the first exhaust pipe is connected and a downstream connection portion to which the second exhaust pipe is connected on one end surface of the second exhaust pipe, and
- both the first exhaust pipe and the second exhaust pipe are on either a right side or a left side of center in the vehicle width direction.
