5655 aftertreatment 1 scr conversion efficiency
Nitrogen oxides (NOx) are the main emissions of diesel engines. Selective catalytic reduction (SCR) is the main technology used to reduce NOx emissions from diesel engines. NOx conversion efficiency and ammonia (NH3) escape are the main indicators to evaluate SCR performance. In this work, the effects of diesel engine exhaust …The Selective Catalytic Reduction on Filter (SCRF) system is yet to be deployed in current heavy-duty diesel engine aftertreatment system. Due to the thermal, space and cost benefits of the SCRF, it could become a useful component of the after-treatment system of a heavy-duty diesel engine, as regulators continue to demand an even cleaner environment.Integrating urea-selective catalytic reduction (SCR) and diesel particulate filter (DPF) technologies into a single device has the potential to reduce the complexity of current diesel aftertreatment strategies. Fundamental studies were performed to shed light on the pressure drop and reaction behavior of integrated SCR and DPF systems. Details of …

The engines were calibrated for low PM emission levels, below 0.02 g/kWh, while engine-out NOx was elevated to about 9-11 g/kWh. SCR aftertreatment was then used to bring down NOx emissions to below 2 g/kWh. The required NOx conversion efficiency of the SCR system was about 80-85% for Euro V and only about 65% at the Euro IV stage.Cummins X12 CM2350 X119B (2018 & Newer) Fault Code: 5655 PID: SPN: 4364 FMI: 31 Aftertreatment 1 SCR Conversion Efficiency- condition Exists.
