EGR blanking / blocking - what is the real deal?

[Wh1stl3r]

I've debated whether to have this done but decided to go for it. The list of harm Nox can do to the environment is pretty extensive. But after seeing how degenerative it is to the engine, (specially with 500 ppm sulfur fuel) I've decided it defeats its intended purpose. It may seem harmless when your car is new, but after a few tens of thousands of Km's your emissions are going to degrade exponentially.

I had it blocked and planted some trees to get rid of the guilt. If ever the time comes that every station had Euro 5 diesel I'd unblock it and maybe use something like Seafoam?

As for using only gasoline powered cars, that may be counterproductive. It would bring the prices of gasoline up if everyone used it. I still think it's better to "use all the parts of the chicken".

I thought EGR valve was closed at idle, and only opened at part throttle. Also delete some messages, I can't send you a PM hehe.

That was also what I thought. However based on my obd2 scanner, its always partly open 20%, then opens more if you baby drive. But if you punch the accelerator, it will just be at 20%. This is on my ranger t6. On my civic fb, its always closed unless you baby drive

20%?! Not good at all. I-block na lang nga. Hehe.

Here's an interesting read comparing the amount of pollutants of diesel and gasoline.
Vehicle Emissions | Air Pollution | City Diesel | LPG | CNG
Gas isn't exactly "cleaner".
