What is high NOx emission?
High NOx emissions can occur when an engine’s air-fuel mixture is too lean. This can happen when too much air is added to the fuel or when too little fuel is injected into the engine. In either case, this causes the mixture to burn hotter.
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.
How does a catalytic converter reduce NOx emissions?
The engine-management system does its best to limit NOx production by carefully regulating the air-fuel mixture and ignition timing. A properly functioning catalytic converter reduces emissions further.
Is there any way to lower engine NOx?
Timing Adjustment Can Lower Nox. Proper ignition timing – a combination of the base setting and advance system – is critical for optimum performance, fuel economy and low emissions. An engine with excessively advanced timing will run well, but is prone to ping (harmful abnormal combustion) and produce excessive NOx.
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 makes a Honda CRX Si so good?
They were cheap, light, precise, and about as mechanically complex as a screwdriver. To say nothing of the little H badge on the front, which meant they were as reliable as the sun. These virtues also came at a small sticker price, further adding to their desirability.
What can I do to lower NOx in my car?
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.
