What can be done about high NOx in smog?
What can be done about high NOx in smog?
The solution to this problem is called De-Carbonizing. It usually costs around two labor hours at a smog check repair station. It will remove a good amount of carbon out of an engine. This will increase combustion space, lower compression and lower NOx. 5. Engine Overheating – Inadequate engine cooling can will high NOx.
What causes high No ( Nox ) in a car?
Nitrogen Oxide or NO is created when an engine’s combustion chamber temperature reaches over 2500F. Vehicle manufacturers have designed several systems, which when working properly, lower nitric oxide emissions. Below are common failures which may cause your car, truck, van, suv, or motorhome to produce high high nitric oxide. 1.
When does the EGR system cause high NOx?
The EGR system’s job is to re-route a small amount of exhaust gas back into the intake manifold to help reduce combustion chamber temperatures. As mentioned above NOx is created when combustion chamber temperatures reach above 2500F.
What can I do to lower NOx in my car?

What to do if your car fails the NOx test?
If you own a non-EGR equipped vehicle, and have failed the emissions test for high NOx, pay close attention to the Catalytic Converter. Read about Catalytic Converter

What causes high No ( Nox ) in the air?
What Causes High NO (NOx)? Nitrogen Oxide or NO is created when an engine’s combustion chamber temperature reaches over 2500F. Vehicle manufacturers have designed several systems, which when working properly, lower nitric oxide emissions.
Why is my NOx so high on my car?
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.
What causes NOx to increase to an abnormal level?
Let’s consider the things that can cause NOX to increase to an abnormally high level. Oxides of nitrogen (NOX) are formed when the combustion chamber temperature exceeds 2500°F (the ignition point for compressed nitrogen). The engine must normally be under some kind of load before it develops such high combustion chamber temperatures.

When do you get high NOx in your car?
Remember high NOx nitric oxide is created when an engine’s combustion chamber temperatures reach over 2500F. You will want to make sure your vehicle’s cooling system is working properly, and your vehicle’s temperature gauge is always indicating normal.
What causes excessive NOx in a GM engine?
The richer the air to fuel ratio (less than 14.7/1), the cooler the combustion will be, the leaner the air to fuel ratio (more oxygen), the hotter the combustion is and more NOx is produced. These particular engines either equipped or not with an EGR system may produce excessive NOx due to a lean condition.
Why does my GM MPFI fail NOx test?
GM MPFI 3200, 3800, engines failing NOx caused by lean condition. General Motors Multiport Fuel Injection engines may fail emissions standard testing due to excess Oxides of Nitrogen levels in the exhaust gas. Here are some steps to determine and correct the cause of high NOx emissions.
Remember high NOx nitric oxide is created when an engine’s combustion chamber temperatures reach over 2500F. You will want to make sure your vehicle’s cooling system is working properly, and your vehicle’s temperature gauge is always indicating normal.
What causes high NOx in a fuel mixture?
1. Lean Fuel Mixture – Lean fuel mixtures cause high NOx. A lean fuel mixture exists when less fuel then required is delivered to the combustion chambers or when more air then necessary is added to the fuel. In either case the lack of gasoline needed to cool the combustion chambers down is not present.
