DC Motor Driven Throttle Bodies and Control Valves Flexible Air Management

DC motor driven throttle bodies and control valves The Pierburg modular ETC system is a consistent extension of the Pierburg air management design philosophy. The principles we have used for more than 40 million production throttle bodies are also utilized in state-of-the-art DC motor driven throttles for a wide variety of applications. Pierburg throttle bodies cover all automotive applications when effective air flow control for both gasoline and diesel engines is needed. The modular design allows a cost efficient utilisation of multiple use components. At the same time the modular ETC sys-...

comfort functions, cruise control, as well as safety functions like antiskid control depend on a highly refined technology and the manufacturing quality of the throttle body. Even current load control concepts for gasoline engines, such as direct injection and variable valve control, require a throttle body either for control or to control any recirculated gas. Pierburg provides individual concepts constituting the best solution for future applications with regard to both function and price. Control valves also serve to regenerate diesel particle filters and reduce engine cut-off vibrations....

ETC-Di, electric control valve for current and future advanced diesel engines Future engines will need improved exhaust gas recirculation precision. Keeping this in mind Pierburg has developed a DC motor driven control valve with integrated position control for diesel engines. The distinguishing characteristic of this component is the high precision positioning of the throttle plate independent of external position control. The desired angle is achieved by the integrated electronics and the drive. The desired position is relayed as PWM signal by the engine controller. Moduleintegrated electronic...

As on the ETC-E a proven drive with DC motor and dual stage train gear is used. The resulting high torque ensures full function throughout its service life despite of recirculating gases and other contaminents, which increase friction. The ETC-Di is easy to adopt to various applications. It allows designs for different diameters and packaging requirements. This given variability led to a further improved variant for HD (Heavy Duty) applications specifically in regards to durability. For the rough environment in trucks the drive is now by EC-motor and CAN communication allows to fulfill known...

Our components are trimmed to customer requirements and could be equipped with DC- or EC-motors as a consequence. Position feedback Position feedback is an integral function of every throttle control system. It serves to determine the throttle plate position precisely and is by such inevitable to control air flow. In between non contact sensors have taken over from the classic potentiometer. Philosophy Pierburg‘s various companies put their expertise in the engineering and manufacturing of these different components – their mechanics and the electric drives – into one overall system. This is...
