Audi A4 Throttle Body

VDO Throttle Body - The Throttle Body valve angle is monitored by throttle electronics, which remain in constant communication with the engine management system. The resulting data is compared in real-time. The optimum throttle valve position is calculated by the engine management system with regard to both fuel economy and emissions. The information is then fed back to the throttle electronics, which adjust the throttle angle accordingly.

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