A side vehicle body structure ensures rigidity and shock absorption performance of the body, avoids widening of the body, and smooths the flow of exhaust gas. Embodiments include an engine, an exhaust apparatus, and a rear pillar extending upward from a rear-side portion of a side sill extending in the vehicle front-rear direction. The exhaust apparatus is disposed along the vehicle front-rear direction on the vehicle-width-direction outer side relative to the side sill. An exhaust system member is located at a going-around portion, with respect to the rear pillar, from the front side to the rear side and from the outer side to the inner side in the vehicle width direction. The rear pillar has a cross section orthogonal to the vehicle up-down direction having a shape in which a portion between front and rear ends is located on the vehicle-width-direction outer side relative to these front and rear ends.

Exhaust assemblies for vehicles and methods of installing exhaust systems on vehicles are disclosed. An exhaust assembly for a vehicle includes an exhaust inlet to receive combustion products from a drive unit, a catalytic converter to control emissions from combustion products received by the exhaust system, and a first piping assembly coupled to the exhaust inlet and the catalytic converter.

The encased exhaust is a traditional aftermarket expansion chamber muffler system for a two stroke engine encompassing a duct fan/propeller. The propeller is mounted directly to the engine's driveshaft, eliminating reduction gears and belts allowing for more airflow and less weight. This eliminates the muffler and replaces the cage on a paramotor, allowing for more airflow through the funneled air duct. The configuration of these two functions exists but not in this sequence, that is what makes this product unique.

An exhaust system member is provided on a vehicle-width-direction outer side relative to a vehicle body structure such as a side sill, while avoiding widening of the vehicle, enhancing shock absorption performance during a collision, and maintaining rigidity of the vehicle body. Embodiments include an engine disposed forward of a vehicle cabin, an engine exhaust system, and a hinge pillar extending vertically. The exhaust system includes a first exhaust system member beside the hinge pillar in the vehicle front-rear direction from the vehicle-width-direction outer side of the hinge pillar and extending forward of the hinge pillar, a second exhaust system member rearward of the hinge pillar, and a connection part connecting these exhaust system members. The connection part has a smaller length in the vehicle width direction than at least one of the first and second exhaust system members, and overlaps with the hinge pillar in the vehicle front-rear direction.

A condensed water drainage device of an exhaust system includes a casing having an inlet on a first side thereof and an outlet on a second side thereof and a deformable member coupled to the first side of the casing and configured to elastically and extendably deform. The drainage device includes a condensed water drainage member coupled to the deformable member to extend the deformable member by pressure of an exhaust gas introduced to the deformable member and having a condensed water drainage hole communicating with the outlet. The drainage device includes a stopper coupled to the second side of the casing to limit movement of the condensed water drainage member and to open or close the condensed water drainage hole according to extension or contraction of the deformable member.

A muffler for an exhaust system of an internal combustion engine includes a muffler housing having a peripheral wall elongated along a longitudinal axis of the muffler housing. The peripheral wall has first and second end walls. A muffler insert is surrounded by the peripheral wall and is supported thereon. The muffler insert has a retaining wall extending in a direction of the longitudinal axis. The peripheral wall has a peripheral wall opening and a first exhaust-gas routing pipe has a first end region and is positioned with the first end region thereof engaging in the peripheral wall opening. The first exhaust-gas routing pipe has a second end region and is secured by the second end region thereof to the retaining wall. The first exhaust-gas routing pipe is of multi-part configuration and has a first pipe part and a second pipe part.

A vehicle including an engine body that has a crankcase that rotatably supports a crankshaft, a cylinder, and a cylinder head provided with an intake port and an exhaust port, in which a central axis of the crankshaft extends in the vehicle width direction, a CVT disposed on a side portion in the vehicle width direction of the engine body, a transmission disposed on one side in a front-rear direction of the engine body, an intake pipe connected to the intake port, an air cleaner connected to the intake pipe, an exhaust pipe connected to the exhaust port, and an exhaust muffler connected to the exhaust pipe. At least a part of each of the transmission, the intake pipe, the air cleaner, the exhaust pipe, and the exhaust muffler is disposed in a region where the engine body is projected in the front-rear direction.
