2.1.5.3. The main features of an air line with variable characteristics (VAD) (L3)

Fig. 2.57. Mazda 6 car VAD system with the L3 engine: 1–VAD system zaslonka; 2–the operating electromagnetic valve of VAD system; 3–vacuum chamber of VAD system; 4–return valve of VAD system


The control system of VAD opens a zaslonka in the case of the air filter at high frequencies of rotation of the engine for increase in an air stream. The system consists of a zaslonka, the electromagnetic valve of management, the vacuum chamber and the return valve. Usually, the core under the influence of a spring opens a zaslonka (fig. 2.57).
