High nox readings
WebJul 22, 2024 · NOx is usually high due to a problem with the EGR valve, its related components that operate it, or clogged pipes between the EGR valve and the exhaust pipe, or, less commonly, between the EGR valve and intake manifold. Thanks! We're glad this was helpful. Thank you for your feedback. WebWhen operated at a steady state of about 50 km/h, five percent EGR on a typical engine can reduce NOX emissions by as much as forty percent. Ten percent EGR can reduce NOX …

WebThe NOx sensor cannot distinguish between NOx and liquid NH3 (DEF). High NOx sensor 2 readings can be caused by DEF getting past the SCR catalyst. This can be the result of a degraded catalyst or a condition that causes excessive DEF on the SCR. After a DPF service regen, the SCR system is purged of excessive DEF. ... rcr racing tourWeb8 rows · High NOx levels are normally caused by high combustion temperatures and … rcr repairWebApr 1, 2024 · High NOx reading.
