Stepper motor
The throttle body is provided with an auxiliary air
circuit. This is enabled by a piston valve controlled
by a Stepper motor.
The Stepper is powered by the control unit only
when the opening must be changed.
The revolution is divided into portions called
"steps".
By changing the opening "steps" it is possible to
properly feed the engine to facilitate the start-up
procedure and adjust the air feeding with cold en-
gine. When the engine reaches the working tem-
perature, the Stepper partly closes again.
