Evolution of Active Grille Shutters 2014-01-0633

Automotive manufacturers are looking for ways to reduce the CO2 emissions of their vehicle fleet. Increasingly, OEMs are focusing on intelligent air flap systems, which enable high cooling capacity through maximum air flow when they are in an open position. In a closed position, they reduce drag and the time necessary to bring the engine up to operating temperatures. Electric vehicles like the Tesla S benefit from Röchling's Active Grille Shutters (AGS) with a total of four independently controlled flap systems and the new generation of actuators. The module extends the driving range through improved aerodynamics and ensures optimized battery cooling and temperature control. Maximum benefit can be achieved if the controlled air flap systems are mounted right in the front to optimize aerodynamics. While adaptive air flap systems are increasingly used to improve aerodynamics today, they can be a key component of a future thermoacoustic engine encapsulation. This presentation is giving an overview about the current active grille shutter systems as well as a prospect for further CO2 reduction when integrated into a thermoacoustic engine encapsulation.
