In 2006 Bosch will introduce a new generation of diesel engine control units with the EDC17. The Electronic Diesel Control (EDC) controls every parameter that is important for effective, low-emission combustion.

EDC17: Ready for future demands
Because the computing power and functional scope of the new EDC17 can be adapted to match particular requirements, it can be used very flexibly in any vehicle segment on all the world’s markets. In addition to controlling the precise timing and quantity of injection, exhaust gas recirculation, and manifold pressure regulation, it also offers a large number of options such as the control of particulate filters or systems for reducing nitrogen oxides. The Bosch EDC17 determines the injection parameters for each cylinder, making specific adaptations if necessary. This improves the precision of injection throughout the vehicle’s entire service life. The system therefore makes an important contribution to observing future exhaust gas emission limits. The improved control functions also open up potential for employing new combustion processes, with even cleaner emissions, such as the process known as “partially homogeneous combustion.”

Specialists from both the Diesel Systems and Gasoline Systems Divisions at Bosch have worked together closely to develop the new generation of electronic control units. This involved the development of a new and improved system architecture, prepared for future standards such as Autosar (Automotive Open System Architecture). The proven plug and housing design of the EDC16 has been retained. The EDC17 therefore satisfies both the present and the future requirements of an engine management system.
