Advanced diesel combustion

Future emission norms will further reduce the vehicle emissions of diesel engines. To meet the goal of achieving these stringent limits while maintaining attractive attributes of marketability, the combustion system needs also to be revised or redesigned in order to achieve the CO2 limits that will be demanded in the future, while simultaneously producing significantly reduced untreated NO2 emissions. In the scope of this article, the basic conditions for the design of future combustion systems shall be discussed. As a possible solution, we will introduce the FEV combustion system HECS (High Efficiency Combustion System), with which very low fuel consumption can be obtained even at high part loads, while producing minimal nitrogen oxides.
