VDO Electromotive Throttle Valves

VDO Electromotive Throttle Valves

In this type of throttle, the butterfly valve, is mechanically linked to the accelerator pedal. The angle of the valve is monitored by the throttle electronics, which remain in constant communication with the engine management system.

The resulting data is compared in real time with a range of information from other onboard sensors and the engine management system calculates the optimum throttle position in terms of both fuel economy and emissions. This information is then fed back to the throttle electronics, which adjusts the throttle angle as required.

The electronic accelerator’s pulse and other available data from the engine management system’s sensors are permanently calibrated. The optimum throttle valve position is calculated from this information. The electronic throttle valve is only activated by the control signal from the engine management system.
