How does an EGR valve work?
an egr valve opens to put inert gases in the combustion chamber to lower the temperature. this is done to reduce NOx emissions that are produced at high temperatures.
What is the EGR valve on a 1999 Buick Century do?
Exhaust gas recirculation (EGR) Basically, it feeds some of the exhaust gas back to the intake manifold and then into the combustion chamber. It lowers the combustion temperature to reduce oxides of nitrogen.
Is it a big problem if the EGR Flow needs replaced on a 2001 Toyota Camry?
Replace the EGR valve. It routs 1200 degree exhaust into the 1800 degree combustion chanbers to decrease preignition and reduce nox.
What problems can an EGR valve cause?
it will cause pinging running your combustion hotter
What happens to the nitrogen in an internal combustion engine?
They become oxides of nitrogen or the emission NOx, this is controlled by the EGR valve to lower combustion temperatures and lower the NOx gas wich contributes to phot chemical smog, the stuff you see in the air.
Can a bad EGR valve cause a catalytic converter to fail?
Short answer: YES! Longer answer: The EGR valve is designed to recirculate some exhaust gas into the intake, in order to cool combustion temperatures somewhat. If the combustion temps exceed 1100 degrees (actually common in gasoline engines) then oxides of nitrogen are produced. these gases are what we see as visible smog. If the EGR valve fails, it can lead to very high exhaust temps which can gradually melt the insides of the catalytic converter. If a failed EGR is combined with a lean fuel mixture, or over-advanced ignition timing, the melting of the converter happens very quickly.
What is erg valve on 2001 ford escape?
EGR valves control the amount of oxygen that enters the combustion process in an engine. If there is too much oxygen and the fuel level is reduced to an economical level, the combustion temperatures become so high that pistons and exhaust valves burn and/or melt, and exhaust manifolds will literally glow red. By carefully controlling the amount of oxygen in the mixture, engineers have discovered a way to reduce the fuel consumption while maintaining an acceptable power level. EGR is an acronym for "Exhaust Gas Recycling", which means that a controlled percentage of combustion gas is allowed back into the engine to lower the percentage of oxygen. A faulty EGR valve can cause too much of the exhaust gas into the engine or worse, not enough. If it's not enough, your engine can literally burn itself to the point that it is useless. It's important to keep your EGR valve operating properly. Placement of the EGR valve is different on the different engine configurations. You'll need to take a look at the replacment EGR valve and look around for yours, or even ask the sales clerk.
Which emissions control system is designed to reduce NOX emissions?
egr valve
How do you clean an egr valve?
Depends on the EGR valve. A good lot of them can be cleaned and reused. New ones can costs hundreds of dollars.The EGR valve works by routing a small amount of the exhaust gases back into the combustion chamber.See the Related link for more information.To clean the EGR valve, you may be required to remove the vacuum hose and clean out the carbon deposits.
What is a egr valve for cars?
Exhaust Gas Recirculation: in simple terms the valve helps by recirculating some exhaust back into the cylinder (when the engine needs it) to reduce the combustion temperature. Combustion at too high of a temp can make the gas in the cylinder burn to early; this reduces the power, creates a knocking noise in the engine, and worsens the emissions.
Where is the egr valve on a 2002 nissan xtrail 2.2 diesel?
The EGR, or exhaust gas recirculation valve, takes inert exhaust gasses drawn from the exhaust system and reintroduces them into the combustion chamber through the intake manifold.
What is an ejr valve?
would you mean a egr valve i worked on car about 15 years never heard of a ejr but if its a egr that would be a exhaust gas recirculation valve keep the internal combustion chamber cool while the engine running at high speeds
