New challenges for combustion control in advanced diesel engines

Against the backdrop of general discussions on the reduction of CO2 emissions, diesel engines will face new challenges in the future in order to meet future emission limits worldwide while maintaining good consumption figures, good driving characteristics, and acceptable costs. One of these challenges is that the fuel characteristics of diesel often varies greatly worldwide, and sometimes even within one country. As part of this article, we will illustrate FEV’s approach for the compensation of different fuel grades during combustion. The basic influencing factors for a possible compensation of the fuel’s influences will be demonstrated and analyzed, and first results for a suitable control concept will be presented.
