Its the percentile of the exhaust that is CO (carbon monoxide). The only thing that can make it high is too much fuel. Nothing else. A car with high CO is running "rich" and consuming a lot more gasoline than necessary.
i would like to know the answer, as I'm buying a 93 Lexus that has failed on the NOX ANY IDEA?......
Auto emits carbon monoxide(CO), carbon dioxide(CO2) and some other gases and particles which pollute the environment. the amount of CO2 compared to total amount of emission in percentage is called as percent of carbon dioxide in auto emissions. %CO2=(Volume of CO2 emitted/Total volume of emission)*100
Yes? And? The idle mix is too rich.
No you will have to take the test in CO.
Depends on what failed on the emission test. HC? CO? NOx? Combination of these? Check to make sure all the vacuum lines are okay. No cracks or anything.
3 major gasses (as checked in an emission test) hydrocarbons, Co. & Nox (oxides of nitrogen) In exhaust gas of diesel engines (at correct fuel mixture) there was 13.8% CO2 (carbon dioxide) and 84.5% N2 (nitrogen).
This blood test measures the amount of CO that is bound to hemoglobin in the body. Blood is drawn as soon after suspected exposure to CO as possible.
Yes. That's what the test is for, your a liability for insurance co.
co= what :)
out of co hold - fel
Timing, vacuum, and carburetor jetting can affect CO levels, keep in mind that high 7% or low will cause high hc readings. set timing to factory setting and adjust carb jets for smoothest idle, probably will slow idle down quite a bit so after that adjust the idle speed screw until idle speed is at normal. you will need to reset after test is done. All settings must be at optimum for burning fuel as co is unburnt fuel, that is why vacuum leaks are not good.
