As an answer to challenges the Diesel engine is facing, IFP has developed a combustion system able to reach near zero particulate and NOx emissions while maintaining performance standards of the D.I Diesel engines, especially in terms of output power and torque. This dual mode engine application called NADITM (Narrow Angle Direct Injection) applies Homogeneous Charge Compression Ignition at part load and switches to conventional Diesel combustion to reach high and full load requirements. This paper presents the latest development of this concept, based on results obtained on a single cylinder engine as well as on a 2.2 l multi-cylinder engine, in term of hardware (combustion system, air loop, etc.), parameter settings (multiple injection, EGR, etc.) and advanced control strategies including observer and multivariable controller. Based on simulation, the results show a large potential for the technology to reach, on a 1810 kg class vehicle, the most stringent emission levels proposed by the UBA (0.08 g/km of NOx) as future EURO V standards.
