Title:
STRUCTURE FOR INSTALLING EXHAUST GAS SENSOR IN INTERNAL COMBUSTION ENGINE FOR SADDLE RIDING-TYPE VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/179673
Kind Code:
A1
Abstract:
Provided is an internal combustion engine which is for a saddle riding-type vehicle and in which an exhaust gas sensor is attached to an exhaust system component constituting a portion of an exhaust device, the exhaust gas sensor detecting the oxygen concentration in the exhaust gas flowing in an exhaust gas passage in the exhaust system component, wherein: a sensor boss (64) is provided on a side wall of the exhaust system component (44); the exhaust gas sensor (50) has, on one end thereof, a detection part (51) protruding into the exhaust gas passage (49), and is provided with a cylindrical sensor case (52) which enables air to be introduced from the other end thereof and is mounted on the sensor boss (64); and a protruding part protruding from the sensor boss (64) of the sensor case (52) is covered with a cover (66) which is liquid-tightly sealed against the outer circumference of the sensor case (52). Thus, a temperature drop due to wetting of the exhaust gas sensor can be prevented to enhance the detection accuracy of the exhaust gas sensor.
