The fuel efficiency benefits and its excellent torque characteristic made the HSDI Diesel to a real success story in Europe - in the meantime some European manufactures have already placed passenger car Diesel concepts successfully on the US market. In the near future the Diesel shall play an important role in achieving future US CO2 targets based on its favourable working principle. Anyway, in order to remain on the US market some further efforts have to be taken to further reduce the gaseous emissions. The development efforts and system costs of the aftertreatment concept play a major role for the whole drivetrain costs. Due to that reason it is mandatory to define an engine and aftertreatment system that can keep the efforts at a reasonable level; at the same time achieving the stringent US emission targets. In addition the fuel efficiency benefits of the Diesel engine have to be secured. Different aftertreatment concepts are compared and evaluated towards the envisaged target achievement considering also the impact on fuel efficiency. The study is focusing short term on fulfilment of ULEV50 scenario based on LEV2 and EU6 technology elements. Detailed results and characteristics of the different systems are being discussed; explaining also the methodology approach and selected operating strategies. To finalize the paper the achieved cycle results are evaluated, closing with an outlook on possible SULEV solutions.
