10 - SQR484F INTAKE SYSTEM
Intake system mainly consists of air induction pipe, air filter assembly, hot wire air flow meter, intake hose,
electronic throttle assembly and intake manifold assembly, etc.
Intake system uses air filter to filter particles and dust in air. The air filtered flows into intake manifold through
electronic throttle assembly and mixes with fuel at the end of intake manifold assembly port to form flammable
gas mixture, which is transmitted to each cylinder uniformly to coordinate with engine operation.
Electronic throttle assembly is a critical part for engine intake system. Its main function is to adjust the intake
passage area according to driver's driving intention. It controls intake air volume to meet intake requirement of
engine in different operating conditions, and sends back position signals of throttle valve plate to control unit
to achieve accurate control.
