High nox readings
WebApr 5, 2013 · For the NOX test you are allowed a higher value at higher speeds. So at 25 with bigger tires and high gearing (lower number) it would be at an RPM equivalent of running 15 mph which should have a lower NOX. For the other tests that makes sense since the allowed limits are reversed. WebDec 7, 2015 · In this video I go over how you can diagnose excessive amounts of Hydro Carbons (HC), Carbon Monoxide (CO) and Nitrogen Oxide (Nox) in your exhaust. I go ov...

WebRemember that CO is a rich indicator; it will be high when the air-fuel mixture is rich. CO is incomplete burning of the fuel and is by-product combustion. CAUSES OF EMISSIONS NOX NOx is formed when combustion temperatures exceed 2500 degrees. Oxygen bonds to nitrogen to form NOx. This is the result of high temperature and or high pressures within WebAs the oxygen is used to form NOx, the oxygen will be used up, causing a lot of hydrocarbons to be unused. The gas analyzer will read high HC, low C0, high 02, low C02, …
WebApr 26, 2024 · Burnt or damaged cables: A burnt or damaged wiring harness can be the root cause of Nox sensor malfunction. In such a case, a virtual inspection will pinpoint the culprit. It may not mean the Nox sensor itself is bad. It could be that internal connectors that read the Nox level are defective. WebHigh NOx readings at the tailpipe are an clear indication that there is a problem in at least one part of the system, but an NOx reading that appears within "normal" ranges or is only …
WebJan 30, 2024 · High NOx is caused by elevated combustion temperatures. Some of things that can cause high NOx readings are, a malfunctioning EGR system, an engine that’s running too hot, an engine that’s running too lean, high carbon deposits in the combustion chambers, and a defective catalytic converter. WebDec 15, 2024 · The PACCAR emissions systems have Nox sensors that default at 3000 ppm. It never gives a reading and throws the fault code.
