An exhaust muffler includes first and second pipes which extend through a casing, and which are disposed so that a downstream end of the first pipe faces an upstream end of the second pipe, wherein the downstream end of the first pipe and the upstream end of the second pipe are disposed so as to be spaced from each other in an axial direction, one end part of a support member having a circular cross section that has a smaller diameter than those of the first and the second pipes is fixed to one of a first lid member covering an opening at the downstream end of the first pipe and a second lid member covering an opening at the upstream end of the second pipe, and the other end part of the support member is slidably fitted to the other of the first and the second lid members.

Exhaust muffler

A saddle-riding type vehicle is provided in which a water-cooled internal combustion engine, a radiator and a fuel tank are supported on a vehicle body frame. A canister that collects fuel vaporized within the fuel tank is disposed in front of the radiator in a vehicle fore-and-aft direction when viewed from a side. This can enhance the effect in cooling the canister.

Saddle-riding type vehicle

A saddle riding vehicle includes a unit swing engine swingably supported on a body frame through a link member, and an exhaust device provided with an exhaust pipe and a catalyst device. The link member is disposed on an upper side of a crankcase. Part of the catalyst device is disposed below a cylinder section and is located in a region between an imaginary line that connects a link member coupling section coupling the link member to the body frame and a front end of the crankcase and an imaginary line that connects an exhaust pipe connection section of the unit swing engine connected with an end of the exhaust pipe and the link member coupling section, in side view. An exhaust device coupling section that couples the crankcase and the exhaust device is provided.

A fuel supply device for an internal combustion engine includes a plurality of fuel injection valves that are disposed side by side in an engine main body or in an intake system component forming part of an intake system, and a fuel distribution pipe that is connected in common to the fuel injection valves and supported via a support part provided on the intake system component or on the engine main body, wherein the fuel distribution pipe is formed from a pipe material, and a restricting member that is a separate member from the fuel distribution pipe is mounted on the support part at a position adjacent to the fuel distribution pipe so as to abut against the fuel distribution pipe to suppress displacement of the fuel distribution pipe from the support part. Thus, it is possible to suppress displacement of fuel piping while ensuring the mass productivity.

A saddle-type vehicle includes a vehicle body frame, a pillion step supported by the vehicle body frame and on which a foot of a passenger is to be placed, a passenger seat supported by the vehicle body frame and on which the passenger is to be seated, an exhaust pipe configured to guide an exhaust gas discharged from an engine to an outside, an exhaust pipe cover covering the exhaust pipe from a lateral outside thereof, and a guard body extending laterally outward from the vehicle body frame, wherein the guard body is disposed below the pillion step and to protrude laterally from an opening part formed in the exhaust pipe cover.

Saddle-type vehicle

A silencer includes conduit with a downstream end portion configured from a tubular member which includes a conduit discharge port extending through a silencer main body and discharges exhaust gas to the outside therethrough. The tubular member includes a resonance communication hole communicating with a resonance chamber and an upstream side communication hole and a downstream side communication hole communicating with a second chamber. A barrier wall serving as a throttle portion for throttling an exhaust path at an intermediate location of the tubular member is provided in the inside of the tubular member and between the upstream side communication hole and the downstream side communication hole.

Silencer for internal combustion engine

An air cleaner structure for a vehicle includes an air cleaner is mounted on a power unit. The air cleaner case is formed in a shape elongated from a side of the internal combustion engine toward a side of the rear wheel. An intake-air outlet passage connected to an upstream end of a connecting tube is formed forward in the front of the air cleaner case. A filter member is placed rearward of the intake-air outlet passage in the case. A blowby gas return passage connected to a blowby gas return pipe of the engine, and an additional air passage are juxtaposed with each other in a vertical direction and formed forward around the intake-air outlet passage in front of the air cleaner case such that the blowby gas return passage is located below the additional air passage. The resulting structure reduces a length of piping to the engine.

An exhaust purifying apparatus achieving placement of components so as to prevent an increase in the size of the vehicle caused by the placement of the exhaust purifying apparatus while maintaining the performance of the exhaust purifying apparatus by secondary air in a saddle-ride type vehicle. An exhaust purifying apparatus of a saddle-ride vehicle includes a secondary air supply pipe of which one end is connected an exhaust passage of an internal combustion engine. A secondary air control valve is connected with the other end of the secondary air supply pipe for controlling the supply of secondary air to the secondary air supply pipe. An outdoor air introduction passage is connected to the secondary air control valve, wherein an air filter for secondary air and a resonant passage are installed in the middle of the outdoor air introduction passage.
