5655 aftertreatment 1 scr conversion efficiency
SCR conversion efficiency is one of the most challenging diagnostics because typical NOx sensors used for control and diagnostics are cross-sensitive to ammonia, which also leads to high warranty costs. ... Referring again to FIG. 1, the aftertreatment system 100 may include a controller 120 structured to perform certain operations to determine ...Aftertreatment operation requires high temperatures. For example, when the exhaust gas temperature is lower than 200 °C, the SCR catalyst activity decreases significantly, resulting in an extremely low NO x conversion efficiency [11]. Diesel exhaust thermal management technologies have been widely used to increase the exhaust gas temperature ...Nov 7, 2014 · Joined: Oct 2013. 1 11-07-2014, 07:35 AM.

7. SCR - Selective Catalytic Reduction System - Completes the clean air process in a diesel engine. Most found on 2011 and newer diesel equipped vehicles The final stage of aftertreatment is the SCR. At this point, the SCR works together with DEF to remove all the remaining NOx and hydrocarbons not filtered by the DOC.Make: DetroitEngine: DD15 GHG17 (2017 & Newer)PID: N/ASPN: 5298FMI: 14. Description: Selective Catalytic Reduction Catalyst Abnormal Temperature Rise. Troubleshooting: DESCRIPTION: Selective Catalytic Reduction (SCR) abnormal temperature rise. MONITORED PARAMETER: Diesel Particulate Filter (DPF) outlet temperature, SCR outlet temperature.1. Introduction. Selective catalytic reduction (SCR) is the most important technology to make a diesel engine meet the increasingly stringent NO x emission regulations. 1 The working process of an SCR aftertreatment system is complex and changeable. The main factors affecting the NO x conversion efficiency are ammonia concentration distribution, exhaust conditions, catalyst activity, and so on.

4364–2 (E1410 (2)) Aftertreatment #1 SCR Catalyst Conversion Efficiency : Erratic, Intermittent, or Incorrect The current troubleshooting procedure does not always resolve the issue satisfactorily. Caterpillar is investigating the root cause of these issues.SCR is a lively emission management technique utilized in diesel systems to manage the Nox emission from the tailpipe of the exhaust system. SCR performs the selective catalytic reduction of harmful nitrous oxide (NOx) to nitrogen (N2) and water (H2O). The SCR technology injects a liquid reductant through the catalyst into the engine exhaust ...Aftertreatment Diesel Oxidation Catalyst: the volatile substances in PM are removed by oxidation reaction through the catalyst on the substrate, mainly eliminating CO, HC, and a small number of carbon particles. ...
