Problems solved by technology

[0008] Therefore, due to the arrangement of the piping, etc., the height of the passenger seat cushion is increased, which increases the size of the vehicle. In addition, if the above is suppressed, the position of the main frame will be lowered, and there will be a problem of restricting the vertical swing amount of the power unit.

Abstract

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.

Description

technical field [0001] The present invention relates to an exhaust purification device in a straddled vehicle such as a motorcycle or a beach buggy, and more particularly relates to supplying secondary air to an exhaust system of an internal combustion engine so as to purify unburned components in the exhaust gas. Exhaust purification device for purification. Background technique [0002] In order to deal with exhaust gas restrictions, in straddle-type vehicles such as motorcycles and beach buggies, a device that supplies secondary air to the exhaust system of an internal combustion engine to recombust unburned components in the exhaust gas is described, for example, in the following patents: Document 1 is published. [0003] The device shown in Patent Document 1 is configured in a motorcycle equipped with a power unit such that the other end side of the secondary air supply pipe connected to the exhaust system (inside the exhaust port) of the internal combustion engine is ...
