Gabatarwa Akwai nau'ikan Venturi Air Flow Control bawul uku：

m iska flow bawul, zai iya samar da kwanciyar hankali gas kwarara;

Double steady halin bawul, zai iya samar da biyu daban-daban gas kwarara, wato, mafi girma da mafi ƙarancin kwarara; Canji iska yawan bawul, za a iya sarrafa iska kwarara ta hanyar rufe madaidaiciya amsa da kwarara feedback sigina ga umarnin kasa da 1 seconds.

Venturi iska kwarara iko bawul hada da inji matsin lamba alaka daidaitawa da high-gudun iska kwarara iko, fadada iska kwarara iko zuwa mafi girma matakin. Ta hanyar aerodynamic zane, bawul yana da shiru aiki aiki.
