Intake system



Functions The design and operation of the intake system Mazda 3 (GG) with engines L3, L8 and LF are the same as on the motor current model FS 323 (BJ), except for the following:
- To improve the maintainability of the throttle tube AAS used.
- Intake manifold is made of plastic to reduce weight.
- Duct system with variable characteristics (VAD) is used to improve engine performance.

Intake system of the car the Mazda 3
Fig. 2.56. Intake system of the car the Mazda 3: 1 - the air filter; 2 - a regulator of idling; 3 - resonance chamber; 4 - control solenoid valve system VIS (L3); 5 - control solenoid valve Variable tumble; 6 - engines L8, LF; 7 - the inlet manifold; 8 - actuator valve system VIS (L3); 9 - actuator valve system VTCS; 10 - non-return valve system VAD (L3); 11 - the accelerator pedal (RHD); 12 - the accelerator cable (RH D); 13 - the accelerator pedal (LHD); 14 - the accelerator cable (LHD); 15 - damper system VAD (L3); 16 - a control solenoid valve VAD (L3)


- Use induction system with variable characteristics (VIS). This system is similar to the system VICS modern model 323 (BJ) with engine FS.
