How does EGR work on Duramax?
How does EGR work on Duramax?
The EGR uses inert gas (exhaust has no oxygen in it) and recirculates that gas into the combustion cylinder. Since 2004.5 they have been used to reduce NoX emissions, act as buffer in the combustion cycle between air and fuel and reduce combustion temperatures.
Where is the EGR valve on a Duramax?
Over time, the EGR valve will clog and will need to be replaced. Disconnect the cable on the negative terminal of the battery. Locate the exhaust manifold on the engine. The manifold will be on the right side, or driver’s side, of the engine, but its location will vary slightly depending on the particular Duramax model.
How do you remove the EGR plug from a diesel engine?
The first option is simple. Simply turn off the truck and disconnect the EGR plug from the butterfly valve. This takes about 15 seconds. It’s important the truck is turned off when disconnecting the cable because the butterfly value is in the closed position during this time (meaning, exhaust gasses are blocked from re-entering the engine).
Why is the EGR Valve Bad for your diesel engine?
So when you reintroduce exhaust back into the diesel engine, you are displacing fresh air that has more oxygen with exhaust gasses that don’t. As a result, the engine doesn’t burn the fuel as well because there is less oxygen. Second, diesel exhaust by its very nature has pollutants in it, including soot in the form of carbon.
How long does it take to close the EGR valve on a truck?
This takes about 15 seconds. It’s important the truck is turned off when disconnecting the cable because the butterfly value is in the closed position during this time (meaning, exhaust gasses are blocked from re-entering the engine). When the engine is on, the valve opens and closes as needed based on the inputs sent from the on-board computer.
What does EGR delete actually do?
- Park your car or place it in neutral with the emergency brake on. Raise your hood and remove the negative battery terminal.
- There’s metal tubing that extends upwards and is connected to the driver’s side exhaust manifold. It’s through this tube that exhaust gas is sent to the EGR valve.
- The EGR valve is on the intake manifold.
What does EGR removal do?
An EGR delete is the device that can be used to block off and delete the EGR cooler or at least the functionality of the EGR system . Most EGR deletes stop or block the flow of exhaust gases from flowing through the EGR cooler. Therefore, it prevent the EGR system from functioning properly.
What is an EGR bypass valve?
EGR DELETE / EGR BYPASS. The EGR valve (Exhaust Gas Recirculation) is an emission control device designed to reduce NOx emissions to help towards the ever more stringent Euro Emission Regulations. Celtic Tuning EGR Delete and EGR bypass software is designed to remove the functionality of the EGR valve to ensure it removes the running issues associated with these devices.
What is an EGR valve delete?
EGR delete is the removal, bypass, defeat, disconnect, damage or in any way rendering ineffective the exhaust gas recirculation device on a motor vehicle. EGR delete is a form of tampering because deliberately doing anything to prevent the EGR valve from working correctly meets the definition.
