How to deisconnect EGR

[Hotplate]

Hi,how can i disconnect Exhaust Gas Recirculation (EGR) in Daewoo/Chevrolet Kalos?

[chronoti]

cut a coke can to the size of the hole and slip it in. that wount really disconect it but it will bypass it. or else you need to read the manual and replace it with a resistor.

you will get, check engine light if you do that.

if it is penumatic then remove the electrical socket going to the solinoid that triggers the EGR

if it is electrical then remove the socket on the EGR valve itself.

What does EGR do?

recycle emission gases.

The exhaust gas recirculation (EGR) system is used on engines tolower NOx (oxides of nitrogen) emission levels caused by high combustion temperature. The EGR valve is a duty control linear type that is operated by the powertrain control module (PCM)/engine control module (ECM). The EGR valve feeds small amounts of exhaust
gas into the intake manifold to decrease combustion temperature.

The amount of exhaust gas recirculated is controlled by variations in vacuum and exhaust back pressure. If too much exhaust gas enters, combustion will not take place. For this reason, very little exhaust gas is allowed to pass through the valve, especially at idle.

Too much EGR flow tends to weaken combustion, causing the engine to run roughly or to stop. With too much EGR flow at idle, cruise, or cold operation, any of the following conditions may occur:
- The engine stops after a cold start.
- The engine stops at idle after deceleration.
- The vehicle surges during cruise.
- Rough idle.

If the EGR valve stays open all the time, the engine may not idle. Too little or no EGR flow allows combustion temperatures to get too high during acceleration and load conditions. This could cause the
following conditions:
- Spark knock (detonation).
- Engine overheating.
- Emission test failure.
