  • Patent number: 8549837
    Abstract: An exhaust upstream section (48) of an exhaust apparatus (E) comprises a plurality of branch pipe portions (32), a plurality of intermediate collector pipe portions (33), a final collector pipe portion (34), and an exhaust gas-purifying unit (40). The exhaust gas-purifying unit (40) is disposed on a vehicle-rear side of an engine (1) to allow a gas passage thereinside to extend approximately in vehicle-widthwise direction, in top plan view. Each of the plurality of intermediate collector pipe portions (33) curves to allow an exhaust downstream region of the intermediate collector pipe portion (33) to be oriented toward one side or the other side of the vehicle-widthwise direction, in top plan view, and the final collector pipe portion (34) curves to allow an exhaust downstream region of the final collector pipe portion (34) to be oriented toward a vehicle-front side, in top plan view.

  • Publication number: 20110126522
    Abstract: Disclosed is an exhaust apparatus (E) for a transverse engine (1) coupled with a transmission (11) located on one side thereof in a cylinder arrangement direction. The exhaust apparatus (E) has an upstream exhaust assembly (48) which comprises a plurality of branch pipe portions (32), a single exhaust pipe portion (34), and an exhaust gas-purifying unit (40). The exhaust gas-purifying unit (40) is disposed on a vehicle-rear side of the engine (1) to allow a gas passage thereinside to extend approximately in a vehicle-widthwise direction, in top plan view. The upstream exhaust assembly (48) includes, on an exhaust upstream side of the single exhaust pipe portion (34), a section which curves to allow an exhaust downstream region of the section to be oriented toward one side of the vehicle-widthwise direction which is a direction coming close to the transmission (11), in top plan view.
