3 Terms and definitions
The terms and definitions as defined in GB/T 28046.1, as well as the following terms
and definitions, apply to this standard.
3.1
Electronic throttle body
An electronic device, that receives control commands from the engine management
system, controls the throttle's opening by driving the DC motor, finally realizes the
control of the engine's air intake; meanwhile can feedback the throttle's opening
position information to the engine management system, in real time through sensors.
It is usually composed of a mechanical housing, a valve plate, a DC motor, a sensor.
3.2
Upper mechanical stop (UMS)
In the case of power failure, the maximum opening position of the valve plate of the
throttle body, when pushed manually (see Figure 1).
The sensor signal output of the electronic throttle body shall comply with the provisions
of the product technical documents.
4.3 Air flow characteristics
4 4.3.1 Air flow at the lower mechanical stop.
The air flow of the electronic throttle body, at the lower mechanical stop, shall comply
with the provisions of the product technical documents.
4.3.2 Air flow at the limb home position.
The air flow of the electronic throttle body, at the limb home position, shall comply
with the provisions of the product technical documents.
4.3.3 Air leakage from bearing.
