18.104.22.168. Admission system
Functions, design and work of system of an admission of Mazda 3 (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.
|Fig. 2.56. System of an admission of the Mazda 3 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)
– 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.
