Bosch Diesel Technology Powers VW Touareg

FARMINGTON HILLS, Mich., Dec. 19, 2002; Bosch today announced it will provide the Unit Injector diesel injection system for the 10-cylinder diesel engine of the all-new Volkswagen Touareg.

The system features two electronic control units which regulate the injection of diesel fuel from the injectors directly into the cylinders -- at a pressure of 2050 bar. The result is an extremely fine dispersal of the fuel in the combustion chamber and a highly efficient combustion process, providing optimum power and an exceptionally clean running engine. With a power output of 230 kW and torque of up to 750 newton-meter, the engine is powerful and very quiet.

The Bosch Unit Injector System (UIS) for the Volkswagen Touareg consists of 10 individual pump-injector elements, each of which supplies one cylinder with fuel. The magnetic valve control delivers the exact amounts of fuel required and regulates the timing of injection with extreme precision. The pre-injection reduces the combustion noise level of the engine. Each of the two control units from the new EDC 16 series regulates one row of cylinders in the V10 engine.

In addition to its diesel system, the Volkswagen Touareg also boasts a range of other Bosch technologies. The airbag control system and the complete wiper system provide improved safety features. The Bosch instrument display plus the navigation and sound systems provide higher levels of comfort and convenience.

Bosch has provided Unit Injector diesel technology to Volkswagen since 1998. First used in the Passat TDI, Bosch Unit Injector technology has also been used in the Golf, Bora, Sharan and Lupo. The Volkswagen V10 TDI is currently the most powerful diesel engine used in a passenger car.

Bosch designs and produces precision automotive components and systems sold to vehicle and powertrain manufacturers worldwide. These include systems and components for gasoline and diesel injection, airbag components, brake systems, telematics, as well as small motors, electrical and electronic equipment.
