AIR INTAKE AND EXHAUST SYSTEM
Exhaust Detecting System
Exhaust detecting system depends on two oxygen sensors
1
mounted on exhaust pipes, and they can detect the air &
fuel combustion degree by measuring oxygen density and
transferring it as an electrical signal to the ECU� If the ECU
thinks that combustion is not thorough, it will adjust fuel injection
in accordance with signals from the Throttle Position Sensor and
1
Intake Air Temperature sensors. By this way, the ratio of air to
fuel can be optimized for thorough combustion.
Air Intake Valve
An air intake valve is a valve which allows fresh air to flow only from the air filter into the engine. Any
air that passes through the air intake valve is prevented from returning. Have a dealer inspect air intake
valves in accordance with the Periodic Maintenance Chart. Also, have air intake valves inspected
whenever stable idling cannot be performed stably, engine power is greatly reduced, or there are abnormal
engine noises�
Air intake valve removal and inspection should only be performed by an authorized CFMOTO dealer.
