Exhaust apparatus for four wheeled utility vehicle
First Claim
1. An exhaust apparatus for a utility vehicle which discharges exhaust gas from a plurality of exhaust pipes connected to exhaust ports of cylinders, the apparatus comprising:
- an exhaust gathering pipe having an exhaust gathering pipe portion connected to the exhaust pipes and a catalyst pipe portion located on a downstream side of the exhaust gathering pipe portion to purify the exhaust gas;
a sensor attaching pipe provided on the exhaust gathering pipe between the exhaust gathering pipe portion and the catalyst pipe portion, said sensor attaching pipe has a base end attached to the exhaust gathering pipe, and a remote end opposite the base end disposed remotely from the exhaust gathering pipe;
an exhaust gas sensor detachably attached to the remote end of the sensor attaching pipe, said exhaust gas sensor having a sensing portion located at a distal end thereof nearest to the exhaust gathering pipe, whereinthe sensor attaching pipe is tilted relative to said exhaust gathering pipe such that the remote end of the sensor attaching pipe is located above the base end of the sensor attaching pipe and away from a surrounding heat source, andthe sensor attaching pipe has a height so that the sensing portion at the distal end of the exhaust gas sensor is located within the sensor attaching pipe.
