Bosch, Ricardo Collaborate on High Performance Gasoline Direct Injection Concept

FARMINGTON HILLS, Mich., July 17 -- Robert Bosch Corporation and Ricardo plc have joined engineering forces to develop an advanced turbo- charged, direct injection gasoline engine system. The prototype system, DI BOOST, will offer superior performance and fuel economy while also being capable of achieving super ultra low emission vehicle (SULEV) standards.

"With global fuel prices at record levels, Bosch is pleased to partner with Ricardo to advance technologies that deliver improved fuel efficiency of gasoline engines," said John Moulton, president, powertrain division, Robert Bosch Corporation. "The DI BOOST concept is a viable solution that by downsizing engine displacement dramatically improves fuel consumption and performance in gasoline vehicles."

Two prototype DI BOOST engines are in development and combine the performance enhancing capabilities of modern valve actuation and turbo charging with the improved fuel efficiency and low emissions of gasoline direct injection. The engines are based on GM's global high-feature 3.6L V6 engine. A premium sport brand vehicle is employed as the demonstrator platform.

"The DI BOOST concept has clear advantages for automakers in offering dramatically improved fuel consumption in parallel with a more rewarding driving experience for the customer and SULEV emissions levels to benefit the environment," said Jeremy W. Holt, president of Ricardo, Inc. and executive director of Ricardo plc. "Ricardo is pleased to continue its partnership with Bosch in developing a vehicle based demonstration of this highly promising gasoline engine technology."

The first phase of DI BOOST, the design and procurement of prototype engines, was completed in January 2006. The next phase, which started in March 2006, concentrates on base engine calibration for best efficiency and driveability. In parallel, vehicle integration is nearing completion. Future phases will focus on achieving SULEV emissions levels via high-pressure start capability and split injection.

Bosch is providing the complete DI Motronic engine management system including the new, second generation direct-injection fuel system as well as ignition, air and exhaust control. Ricardo has contributed to the study using its expertise for prototype powertrain integration and providing base engine calibration work on modern engine dynamometers in Belleville, Mich.
