The computing power and functional scope of the new EDC17 unit can be adapted to match particular requirements giving it the flexibility to be fitted in any vehicle segment across the world. In addition to controlling the precise timing and quality of injection, exhaust gas recirculation, and manifold pressure regulation, it also offers options such as the control of particulate filters or systems for reducing nitrogen oxides. The Bosch EDC17 unit determines the injection parameters for each cylinder, making adjustments if necessary. This improves the precision of injection throughout the vehicle's entire service life and allaows the system to observe 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 homogenous combustion.'

Specialists from the Diesel Systems and Gasoline Systems divisions at Bosch have worked 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 proved plug and housing design of the EDC16 has been retained meaning that the new unit satisfies both the present and the future requirements of an engine management system.
