Neue Technologien für Abgasnachbehandlung

The post Euro6 and post Tier4, respectively Tier5, emission legislation will not focus on further reduction of the emission limits, but will introduce more stringent test condition and on board diagnostic requirements. Life time stable emissions are already one key requirement for heavy engines and also for passenger car with the coming RDE legislation this will be one of the challenges leading to increased system complexity. On the other hand, the requirements listed in Figure 1 has led to an increased complexity of the diesel powertrain including the after treatment systems. Both passenger car and truck engines are facing the challenge to further reduce CO2 emissions to meet future limits and avoid penalty cost. Thus system complexity reduction must be combined with CO2 reduction.

Diesel Engine Potentials by Hydraulic Tuning of the G4S Solenoid Common Rail Injector with 3-Way Function

The emission legislation for diesel engines, both heavy duty and passenger car diesel engines, have been strengthened in the last years significantly. Currently no further reduction of emission limits is planned but still legislation changes will require further improvements as briefly summarized in this introduction chapter.
