direction, loosen fuel pipe.
* Hold seat collar firmly, pull fuel pipe off as arrow direction.
(5) Fuel rail
Fuel rail is used for distributing fuel into fuel injector and fixing fuel injector.
(6) Fuel injector
This system uses top fuel supply single hole fuel injector. Fuel injection pressure is 3.5bar，
output fuel is continuously atomized and in cone angle (15°angle from fuel injector axes )。
The control logic of fuel injector is: phase, sequence control. Four fuel injectors is controlled
according to four cylinders air intake sequence, opening in power stroke till intake stroke start.
Fuel injectors are fixed on fuel rail. Fuel rail press injector onto the fixed seat of intake
manifold, and is sealed by 2 O-rings.

2. Air system
Air intake system mainly consists of air filter, intake hose, intake manifold, idle step
motor and throttle valve body of throttle position sensor.
