Throttle Body

Throttle body assembly mainly consists of the

bearing, shaft and valve plate, return spring,

throttle wire part, throttle position sensing system,

and bypass air volume control system. All of the

above subsystems work together to meet the

requirements for following functions:

Intake flow control

Control of air flow at idle speed

Throttle position detection – provide

throttle opening feedback signal for engine

control system

Throttle body position sensor provides ECU

with throttle opening; the stepper motor at throttle

body maintains the idle speed of engine near the

target idel speed required by ECU;

28mm inner diameter

maximum flow: ≥50g/s@2.7kPa vacuum

Breakaway torque of throttle body:

Idle speed state: 0.12±0.03 N•m

Full opening: 0.32±0.05N•m
