What happens if EGR valve is disconnected in a car?

Yes it might affect the environment but no harm to engine as such. there are people who are running without EGR for more than 50k km. Also in all remapping they disable the EGR.

Why does the fuel management light stay on when the EGR is open?

This means the amount of hydrocarbon gases emitted from the tailpipe increases significantly producing a fuel smell. Your engine management light may stay on once your car detects an issue with the EGR valve. This could be caused when the EGR is either constantly closed or open.

Can a vacuum be used to open an EGR valve?

A vacuum-operated EGR valve is usually only found in older vehicles. It is a straightforward system which utilises a vacuum to switch the EGR valve from closed to open. The vacuum is often regulated by a computer-controlled solenoid.

How does EGR reduce the production of NOx?

To reduce the amount of NOx pollutant emitted from your vehicle, exhaust gases need to be cooled before being emitted from your vehicle. In order to achieve this, they are introduced back into the combustion chamber via the exhaust gas recirculation (EGR) valve; this reduces the temperature and thereby inhibits the production of NOx emissions.

What happens when you disconnect the EGR valve?

Disconnecting the EGR valve leads to EPA enforcement. Disconnecting the EGR valve leads to EPA enforcement. My 1980 Chevy V-8 with 120,000 miles used to hesitate at take off, and buck at speeds above 50 MPH. I discovered that when I disconnected the EGR valve, the bucking disappeared and the engine ran great.

What does the EGR do in a car?

Why do I need an EGR blanking plate?

Reason’s An EGR Blanking Plate May Not Be The Best Solution. With proper maintenance, the EGR system not only runs fine, but your engine runs fine as well. The EGR is there to reduce emissions. Of the big three emissions from a petrol or diesel combustion engine, the EGR reduces the worst one: NOx.
