SOx ana nox
nox is from exhaust temps too high or a cat. convertor breakdown.
At the end of the process, the purified exhaust gasses are sent to the boiler or condenser or other equipment, or discharged into the atmosphere.
Several things can cause high NOx: lean mixture, bad 02 sensor,exhaust leaks before the catalyst, a defective catalyst, high engine compression (carbon buildup), are among the most common.
The spell nox is the opposite of lumos. Lumos causes light to appear at the end of the caster's wand, so nox extinguishes the light emitting from the wand.
NOx in the emission system would be the engine temperature burning to hot there could be a couple of problems but most of the NOx problems are a failing egr valve it circulates air in the engine and exhaust to help keep he engines running temperature down i would say replace the egr valve and your set
Bad EGR, Exhaust Gas Recirculation valve. That is what reduces NoX emissions
Nox is The abbreviation of Oxide(s) of Nitrogen. These are only produced at high burn temperature's. In a modern engine excess Nox emissions can be caused by a lean fuel mixture caused by a failed O2 sensor(s) Or A failed or pluged EGR valve
Check your EGR valve. I have a 95 Accord and failed with High NOx, double the limit. I replaced the EGR valve and cleaned the EGR ports on the intake, they are under the fuel rail. I passed on the second attempt. The ERG valve was 140.00. It took a few hours to scrape the carbon off the clogged ports, some carb cleaner helps.
Oxides of nitrogen (NOx) are primarily formed from combustion processes, such as in vehicles and industrial sources. Nitrogen in the air reacts with oxygen at high temperatures inside engines or industrial furnaces to form different oxides of nitrogen, including nitric oxide (NO) and nitrogen dioxide (NO2). Atmospheric nitrogen can also react with lightning or UV radiation to produce NOx.
No it will not because NOX is in the engine and picks up spark knock and the ECM adjusts the timing as needed. The O2 Sensor is in the exhaust and measures the air to fuel ratio then the ECM adjusts.
Petrol engines produce oxides of nitrogen (NOx) as a byproduct of combustion at high temperatures. Specifically, nitrogen in the air reacts with oxygen in the engine's combustion chamber to form NOx gases. Factors such as high compression ratios and combustion temperatures can contribute to increased NOx emissions from petrol engines.
