2.1.5.2. Admission system

Functions, design and work of system of an admission of Mazda6 (GG) with L3, LF and L8 engines same, as well as on the FS engine of modern model 323 (BJ), except for the following:
– for maintainability improvement the throttle branch pipe of AAS is not used.
– the inlet collector is made of plastic for weight reduction.
– the air line system with variable characteristics (VAD) is used for improvement of characteristics of the engine.
– the admission system with variable characteristics (VIS) is used. This system is similar to VICS system of modern model 323 (BJ) with the FS engine.

Fig. 2.56. System of an admission of the Mazda 6 car: 1–air filter; 2–idling regulator; 3–resonant chamber; 4–the operating electromagnetic valve of VIS system (L3); 5–the operating electromagnetic Variable tumble valve; 6–engines L8, LF; 7–inlet collector; 8–executive mechanism of a zaslonka of VIS system (L3); 9–executive mechanism of a zaslonka of VTCS system; 10-return valve of VAD system (L3); 11-pedal of management of supply of fuel (R.H.D); 12-accelerator rope (R. H. D); 13-pedal of management of supply of fuel (L.H.D); 14-rope of an accelerator (L.H.D); 15-zaslonka of VAD system (L3); 16-the operating electromagnetic valve of VAD system (L3)
