• Diesel technology combines maximum performance with low consumption
• Specially adjusted Bosch common rail system

An Audi R10 TDI sports racing car scored a unique victory at this year’s world famous 24-hour endurance race at Le Mans by becoming the first diesel-powered car to win the prestigious event. Another Audi R10 TDI finished third. The victory marked further success for the motor racing alliance between Audi and Bosch with the two companies jointly developing the injection system for the R10 TDI with Bosch supplying high pressure pumps, injectors and the engine control unit for the motor racing common rail system.

The past few years has seen Audi win several races at Le Mans with the previous vehicle, the R8, which was fitted with the Bosch developed FSI direct injection system. “We are pleased that this year we were able to play our part in racing success with our innovative diesel injection equipment,” explained Dr. Ulrich Dohle, president of the Bosch Diesel System division. “In recent years, high performance and low consumption have already helped the diesel engine to success in series-produced models. Now the diesel has also shown what it can do on the race track.”

As development partner, Bosch supplied the specially adjusted high-pressure pumps and piezo-inline injectors for the common rail injection system installed in the R10 TDI. Its engineers have also used specific data gained from working with Audi Sport as the basis for developing the new electronic control unit for the car’s 12-cylinder engine. When developing the injection system, the greatest challenge was the variable control of the extremely high injection pressure. Bosch also supplied the telemetry system that ensured an uninterrupted transmission of data from the vehicles to the pits during the race.

Motor racing services at Bosch has a long history dating back to 1903 when Bosch engineering first helped racing drivers to victory. Today, Bosch has pooled all motor racing activities into one unit, named ‘Bosch Motorsport’. It is part of Bosch Engineering GmbH, the Bosch subsidiary that specialises in engineering services.
