Mounting structure for air-fuel ratio sensor in motercycle

摘要

To provide a mounting structure of an air-fuel ratio sensor on an exhaust pipe in a motorcycle (10) wherein the concentration of oxygen in an exhaust gas can be detected by the air-fuel ratio sensor efficiently and accurately. An air-fuel ratio sensor (50) is mounted on a manifold (34) of exhaust pipes (32a and 32b) connected to the cylinders of an engine. The air-fuel ratio sensor (50) is located upstream of catalytic converters (38a and 38b) provided in the exhaust pipes (32a and 32b).
