Abstract: An exhaust structure of a vehicle is provided that can ensure an arrangement space for a mounted component below a floor panel and prevent thermal damage to the mounted component by reducing sizes of an engine and an exhaust silencer. An exhaust structure of a vehicle includes: an engine disposed in an engine bay formed in a front part of a vehicle; a silencer that reduces noise of exhaust gas from the engine and discharges the exhaust gas outside; an exhaust pipe that couples the engine and the silencer; and a battery unit disposed behind the engine and below a floor panel, the silencer being disposed between the engine and the battery unit.

Abstract: An engine exhaust device includes: a first catalyst; a second catalyst; and a tubular connecting member. The connecting member includes: a first opening; a second opening; and a bend connecting. A downstream end surface of the first catalyst is connected to the first opening, and an upstream end surface of the second catalyst is connected to the second opening. The downstream end surface and the upstream end surface form a dihedral angle within a range from 60 to 120 degrees. A part of the upstream end surface of the second catalyst includes an overlap that is close and opposed to a part of a surface of the first catalyst. The bend of the connecting member includes: a first wall; a second wall; and a connector. The first wall has a curve. The curvature radius of the first wall is greater than the predetermined curvature radius.

Abstract: An engine exhaust device includes: a first catalyst; a second catalyst; and a connecting member shaped into a tube and forming a part of the exhaust path, and connecting the first catalyst to the second catalyst. A downstream end surface of the first catalyst and an upstream end surface of the second catalyst form a dihedral angle within a range from 60 degrees to 120 degrees. A part of the upstream end surface of the second catalyst is close to and faces a part of a side surface of the first catalyst. On a cross-section including a central axis of the first catalyst and being parallel to a central axis of a second catalyst, a length of the part of the side surface of the first catalyst is longer than or equal to 10% and shorter than 50% of an entire length of the first catalyst.

Abstract: An exhaust-gas discharge port to discharge a main flow of exhaust gas passing through an exhaust-gas purifying device is provided at a position which is offset, on one side, from a center axis of the purifying-device body, and an EGR-gas takeout port is provided at a position which is offset, on an opposite side to the exhaust-gas discharge port, from the center axis of the purifying-device body.

Abstract: A downstream-side exhaust-gas takeout portion of a pressure-difference detector is provided between an exhaust-gas discharge port of a downstream-side cover and an EGR-gas takeout port so that a stable exhaust-gas pressure can be taken out (detected).

Abstract: An engine exhaust device includes: a first catalyst; a second catalyst; a connection member and an exhaust gas outlet pipe. The first catalyst has a downstream end face and the second catalyst has an upstream end face. The downstream end face and the upstream end face form a predetermined dihedral angle. The upstream end face of the second catalyst and a side surface of the first catalyst closely face each other to form an overlap. A center axis of the exhaust gas outlet pipe is offset further toward the first catalyst than a center axis of the second catalyst is.

Abstract: A exhaust gas purifier includes a case having a flat transverse section including a pair of facing short sides and a pair of facing long sides, and configured to house a catalytic converter, and an inlet cone including a conical portion, and configured to connect an outlet of the turbine to an inlet of the case. The conical portion includes an inclined wall inclined from a mainstream of the exhaust gas to increase the transverse section of a path of the exhaust gas. A recess recessed inward is formed in a portion corresponding to each of the long sides of the inclined wall of the conical portion.

Abstract: A vehicle reinforcing member includes first and second pistons movable in an axial direction in a cylinder. An inside of the cylinder is sectioned into a gas chamber and a main liquid chamber by the first piston, and the main liquid chamber is sectioned into a first sub-liquid chamber and a second sub-liquid chamber by the second piston. Gas is sealed in the gas chamber, and liquid is sealed in the first and second sub-liquid chambers. A piston rod is coupled to the second piston. The cylinder and the piston rod are respectively coupled to two locations of a vehicle body. A communication path connects the first sub-liquid chamber to the second sub-liquid chamber. A moving amount of the liquid in the communication path is adjusted by an adjuster such that a moving load through the second piston is adjusted.

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.
