2014 Defender 110 Puma 2.2 USW Corris Grey

Blimey I have to say you are very passionate about this.

It might be worth letting go of the stick.

Where do they get all the toxic metals and materials to make these things. I've heard but I must admit pub talk that it does more harm to the environment making these things as it saves. Also when you replace them where do they put them? Local tip? Same as the Prius takes an awful lot of fancy materials to make that car.

Not passionate, just the principle of the thing really. There's no stick to let go of, it's a conversation on an open forum. It looks like a lengthy debate as it plays out over a number of days on here rather than the 10 mins it would probably take if it was discussed face to face!

The tables you posted are interesting but with regards to the EGR Nitrous Oxide as far as I am aware (I may be wrong) is not measured in the UK at present? If you go through life with your head in the sand....all people will see is an ar5e!!

I didn't know we made cats. For some reason I thought they were made in Norway.

Once they have gathered in all the bad stuff our engines produce, how do they dispose of them.

I am in the camp of more mpg less fuel used, less damage to environment.

Oh buy the way I have a de-cat pipe for sale for a 2.4 if anyone is interested! Don't think I'll get much for it now.

So in terms of the environment it's not that good. You make them and your defender doesn't have one that says a lot. I've driven TD5 without and they seem a lot freer.

Maybe so, but if the cat isn't present it's a fail regardless of emissions.

That does seem to be the case going forward but that wasn't the point of my comment. It was merely to highlight the fact that passing the current emissions test with good results was not related to the presence or otherwise of those components, as the equipment used doesn't test for what they do.

Regardless of the legalities, CAT's on diesels are a strange phenomenon. Their fitment seems to have been driven by a political desire to be seen to be doing something rather than sound engineering as, generally, diesels don't run hot enough for them to work properly anyway. That same political desire also saw the death of lean-burn petrol engines, which held a lot of promise in terms of efficiency and low emissions but weren't compatible with the CAT technology being imposed and so development was dropped.

A DPF, by comparison, should be a positive thing, as it's intended to solve one of the biggest problems with diesels, i.e. soot. It's just a shame that they seem to have been implemented so poorly, being prohibitively expensive to replace and requiring even more fuel to be burnt just to make them work. 'You couldn't make it up' is the phrase that springs to mind.

As an aside, i read recently that there's more carbon in the air from tyres wearing down (which have a high carbon content to make them black) than from exhaust emissions which, if true, makes a mockery of the whole thing. Darren

lol not my choice really lol i did bring it up with our enviromental guy but he said it would cost to much the company i work for are the reason the lez was implemented yet if we breach emmisions we do pose being shhut down or hefty fine in the millions

no my truck doesnt have a cat and yes i thinks mines freer too
my bosses were shocked when i said that ididnt have one on my car
