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.
