A series of tests run on the fully transient engine test benches, in Redwitz, Germany, clearly demonstrate that SCR technology is effective in both NOx and particulate emissions reduction. With different particulate measuring technologies, influences of parameters like the sulfur content of the fuel and the influence of the reducing agent are examined. A reduction of the particulate within the health-relevant range (around 100 nm) is proven. Apart from an effective reduction in the organic fraction of the PM, the system is also able to reduce the carbon fraction. Over the ESC / OICA cycle a decrease of elementary carbon of approximately 25% is obtained. Using an SCR system, a clear decrease of the nano-particulate mass emissions is found under all dosing conditions up to approximately 70%.
