Electronic throttle body

Function

The electronically controlled throttle-valve device (DV-E) is the central actuator element in the ETC/E-GAS system for gasoline engines. It comprises the throttle valve with electric drive and throttle-valve-angle sensor.

Using the position of the accelerator pedal, the engine control unit calculates the required opening of the throttle body, the ignition angle and the quantity of fuel to be injected.
A DC motor adjusts the throttle-valve shaft through gearing. The advantages here are: High torque levels, low energy consumption, low weight, and tried-and-tested reliability.
The throttle body angle sensor monitors the current position
of the throttle body and thus permits the position of the throttle valve to be precisely maintained.
