E1389 - Aftertreatment #1 SCR Operator Inducement. This key is an inducement associated with an emissions system fault. The engine is derated, limited to low idle, and can encounter 5 minus rolls shutdowns. Aftertreatment #1 SCR Operator Inducement - E1398 Code. Probable Causes - Codes to the "Selective Catalyst Reduction System" ECMSCR 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. ... Systems, methods, and apparatus for reductant dosing in an scr aftertreatment system US9181835B2 (en) * 2013-08-13: 2015-11-10: Caterpillar ...The engine control module (ECM) monitors the NOx concentration in the engine’s exhaust gases using an aftertreatment intake NOx sensor and an 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. Component Location

Cummins SCR technology is a proven system that has been used in hundreds of thousands of applications throughout North America and Europe. It reduces oxides of nitrogen (NOx) to near-zero levels through the injection of Diesel Exhaust Fluid (DEF) upstream of the catalyst. Customers can expect 3% better fuel efficiency,Cummins 6.7L ISB, Code 5655, "Aftertreatment SCR conversion.

" What is needed to repair this issue? ...To meet increasingly stringent emission regulations, diesel engines must be equipped with DOC, DPF and SCR. Five performance parameters including system back pressure, HC conversion efficiency, conversion efficiency of NO to NO2, passive regeneration rate, and conversion efficiency of NO to N2 are very important for DOC+DPF+SCR system. Nine structural parameters including rDOC, rDPF, rSCR ...Possible causes of this fault code include: All Categories All Products; Truck Software
Figure 2 illustrates the operating principle of the Swirl Cap mixer and the most important variation parameters. AdBlue is dosed into a swirling flow which is generated in the mixing tube. In order to meet demanding installation space conditions, the mixer was designed so that a pipe length of 1.5 times the pipe diameter between the outlet DOC or DPF and inlet SCR is sufficient for good ...SPN 4364/FMI 18.
