Should we blank out the EGR knowing what we know?

[ldrego]

This is an open question. Should we blank out the EGR if we know it increases the NOX particles in the air. I believe these are harmful elements that can affect the lungs. Any thoughts and is there any benefits in cleaning out the EGR system instead.
Thanks all. I am thinking of reinstalling my valve back on the machine.

certainly an issue in urban areas , particles are so small they enter the blood stream through the lungs,cleaning would help

Buy EV if you give a toss

We should all give a toss if it is just a simple matter of cleaning out the valve and putting it back on.

if it bothers you that much, sell your big 4x4 diesel landy and buy a horse!

Took my cats off my v8 and gave them a home in garage

Passes mot every time

did you know, NOx actually causes global cooling as it destroys methane molecules which cause global warming. human activity causes global warming which allegedly damages the earth. NOx kills humans (who are the cause of damage to the planet) and counters global warming.
so... blank your EGR and save the earth!

IMO this thing with the EGR is more complicated than it appears IMO, without EGR it's a fact that the amount of NO3 will be a bit more, but not some huge difference believe me, and that's the only purpose of it, to reduce that emission... i made a comparison on my car cos i have afriend at a MOT station with active EGR and vacuum removed from it and the difference was 4 units, 261 with EGR and 265 with it blocked, BUT i've seen cases when a de-EGR'd one had better emissions, so i made a test with EGR but MAF unplugged and it gave us 290... IMO they did something to reduce the emissions forced by law but it's not well engineered at all, if you read the EGR description you'll see an interesting statement there :

"Recirculating too much exhaust gas can result in higher emissions of soot, HC and CO due to insufficient air. The recirculated exhaust gas must be limited so that there is sufficient oxygen available for combustion of the injected fuel in the combustion chamber, to do this the Engine Control Module (ECM) is used to control the precise quantity of exhaust gas to be recirculated in accordance with the prevailing operating conditions. Influencing factors include:
-the mass of air flow detected by the mass air flow sensor. + ENGINE MANAGEMENT SYSTEM - Td5, DESCRIPTION AND OPERATION, Description.
-the ambient air pressure, determined by the ambient air pressure sensor which is used to initiate adjustments to reduce the amount of smoke produced at high altitudes. + ENGINE MANAGEMENT SYSTEM - Td5, DESCRIPTION AND OPERATION, Description"

we all know how often the MAF can fail and as it's there mainly for EGR controll the overall pollution can be worst from one with EGR than from one without it that's sure so my conclusion is that removing it it's a win-win situation​

Just another thought - there were rumours a while ago that an EU reg would force the MoT test to check for the presence/functionality of the EGR valve if it was fitted at the factory, in the same way that a cat is checked... so if anyone is thinking of removing their EGR it might be worth keeping it for refitting as required.

The EGR valve argument is one that only a good unbiased scientist will be able to win - yes, the valve reduces some pollutants, but it also decreases performance and increases fuel consumption albeit marginally. So fitting the valve reduces some pollutants, but overall does it make the engine more polluting due to the increased fuel being burnt???

People talking about pollution and the like on a 4x4 forum...you couldn't write about it lol

Fit a 3mm plate between the valve and manifold, it's technically still there but circumvented, can't fail you for it being missing then, same as when we gutted the cats on the V8s, open them up on the top, empty contents and weld it back up.

No harm in trying to reduce your emissions or does it make you more macho by having higher emissions? Not sure? We all have our reasons for owning land rovers and I appreciate that some owners may be trying to get more fuel economy out of them (although by your argument , you would think that Land rover owners ,would not give a damn about fuel economy). As for speed and responsiveness I can think of many other cars that are much better than these beasts.

I have kept it just in case of that too.

do what you want. but if you were that bothered, you'd buy a different vehicle.

meanwhile across the pond they turn up the smoke https://www.youtube.com/watch?v=3tKJ6oZOkNo

I prefer economy as that is less overall pollutants.

Raising fuel consumption to lower one thing always seems like a silly idea.

More emissions means machoness?? the fumes really have got to you lol
Fuel economy and carbon footprint or fumes or whatever are completely different things entirely.
