TT Electronics has collaborated with Volkswagen-Audi Group and Saleri to develop an electrically driven 50W water-pump controller (EWPU) for the turbo-intercooler circuit of the EA288 2.0-litre turbo diesel engine used in the Audi A3, A4, A6 models. The controller helps increase fuel efficiency by reducing load on the engine crank, and reduces emissions by assisting faster warm-up.
The EWPU is optimised for mass-market deployment, and meets high performance and reliability targets using conventional assembly technologies with a specially designed frameless EMC filtering circuit. Sophisticated motor control and diagnostics ensure smooth running and maximise reliability, while the option to connect to the vehicle’s LIN infrastructure provides scope for richer communications.
“Our expertise in EWPU development, spanning applications from high-performance cars to the latest generations of clean, economical vehicles, made TT Electronics the suitable technical partner for the EA288 project,” said Johann Maier, Product Line Director, Power Modules, TT Electronics.
