An integrated aftertreatment system consisting of diesel oxidation catalyst (DOC), catalytic diesel particulate filter (CDPF), and selective catalytic reduction (SCR) is an effective way of reducing both NOx and particulate matter (PM). In this paper, the effect of DOC + CDPF + SCR on NOX and particle emissions is investigated during different …It takes like 5 min and the sensor can cost 2-3 hundred bucks. Details for Cummins fault code: 3545. 3226-10 Aftertreatment 1 Outlet NOx Sensor - Abnormal Rate of Change. Reason. Aftertreatment Outlet NOx Sensor Circuit - Abnormal Rate of Change. The aftertreatment outlet NOx sensor reading is not valid. Effect.SPN 4364/FMI 1. Description. This fault code sets when the Aftertreatment Control Module (ACM) detects that the NOx conversion is lower than a calibrated threshold. Monitored Parameter. Selective Catalyst Reduction (SCR) Inlet NOx sensor, SCR outlet NOx sensor. Typical Enabling Conditions. Diesel Exhaust Fluid (DEF) dosing enabled, 1000 - 1500 ...gen oxide. A SCR system can subsequently remove up to 90 percent of the nitrogen oxide produced during the combustion process from the exhaust gas. Fig. 4: Schematic of the operating principle of the SCR system In the SCR catalytic converter, ammonia converts the nitrogen oxides into water vapor and nitrogen. For this

Knowing the other codes you're seeing would be helpful in pinpointing the issue. Until then: Make sure your DEF isn't crap first. Old DEF that's become diluted is the most common cause of SCR problems. You can check it with a refractometer.

So I did the second regen right after ...The SCR temperature is a crucial factor in NOx conversion efficiency. Fig. 4 depicts the SCR temperature during the cold and hot phases of WHTC and NRTC. For the WHTC tests, at the start of the cold phase, the temperature was not enough to inject ammonia, but it reached 100 °C after 92 ± 10 s, at which point ammonia injection commenced.

420 divided by 60 The ECM monitors the NOx concentration in the engine’s exhaust gases using an aftertreatment intake NOx sensor and aftertreatment outlet NOx sensor. By comparing these two values, the ECM is able to determine the conversion efficiency of the SCR catalyst and dosing system. random wrestler name generatorfinnerty's 18 cost Control Challenges for Optimal NOx Conversion Efficiency from SCR Aftertreatment Systems. 2009-01-0905. The regulated emissions of NO x and particulates from diesel engines are low enough that in many cases the emissions levels cannot be met by system architectures based on improved in-cylinder combustion technologies alone. brashear funeral home brunswick mo Joined: Oct 2013. 1 11-07-2014, 07:35 AM.
