jeebowhite Posted July 23, 2015 Share Posted July 23, 2015 So, After watching a video previously, I began to understand that the EGR gasses where introduced AFTER the turbo and where not injected into it.... Right? Well... thats the question!? Does it go in before the turbo and travel through, or does it go after? So I have had a look and most the info I can find suggests it goes in after.... So I want to see what other people thing... Hopefuly Mondeo TXS 2.2 comes along and joins in, as we did kinda hijack that other thread, though it was related... :p lol So, heres one quote from another forum 2. The exhaust is added to the high-pressure air as it goes into the intake manifold, after the turbo compressor and after the intercooler, the last thing before the engine itself. The exhaust doesn't go through the intercooler. The exhaust is coming from the high-pressure side of the exhaust manifold, before it goes out through the turbo. So, that seems to agree with what I understand... Turbo or turbine air induction does not mix with EGR and modern clean diesel requirements. that was a comment from a youtube tutorial... I am curious... first off... does it actually go into the turbo, and secondly, what is everyone else s belief? I was always dubious about things like turbo cleaners in the oil tank, it never made sense, I knew the EGR spewed gas out and back in, but I was never sure whether it was re-injected prior to, or after the turbo, but I must admit, I always thought it was after... Will be interesting to get peoples thoughts :) 1 Quote Link to comment Share on other sites More sharing options...
stef123 Posted July 23, 2015 Share Posted July 23, 2015 If i'm picking up what your asking then yes the above is correct. the exhaust gas is added just before the intake manifold where is meets with the intake air from the turbo via the intercooler. 1 Quote Link to comment Share on other sites More sharing options...
MONDEO TXS 2.2 Posted July 23, 2015 Share Posted July 23, 2015 Exhaust gas drives the part of the turbocharger which then impels & compresses air from the intercooler into the cylinders, resulting in a bigger bang ! One of many benefits of blanking the E.G.R.V. is that all the exhaust pressure ( energy ) spins the turbocharger faster resulting in more power. 1 Quote Link to comment Share on other sites More sharing options...
MONDEO TXS 2.2 Posted July 23, 2015 Share Posted July 23, 2015 Therefore the exhaust gases & the turbocharger function are inextricably linked :) 1 Quote Link to comment Share on other sites More sharing options...
MONDEO TXS 2.2 Posted July 23, 2015 Share Posted July 23, 2015 An E.G.R.V.'s sole purpose is to reduce Nox emissions by recirculating cooled waste exhaust gases into the combustion chambers - lowering the combustion temperature - blanking the E.G.R.V. sends these gases where they should go - through the turbo resulting in more power amongst many other benefits 2 Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted July 23, 2015 Author Share Posted July 23, 2015 The vacuum caused by the air going in after the turbo and pulling the air through the turbo helps to spool the turbo, but when you disable it, the exhaust vacuum produces the same effect, or better. This is why I dont believe turbo cleaners can possibly work. If the gas never goes near the turbo (in essence, its always blown away from the turbo - by the turbo) then the cleaner cannot reach the turbo? 1 Quote Link to comment Share on other sites More sharing options...
MONDEO TXS 2.2 Posted July 23, 2015 Share Posted July 23, 2015 I've never used turbo cleaner but I believe it's sprayed directly onto the vanes inside the turbo body & this is the only simple way to clean them internally ? 1 Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted July 23, 2015 Author Share Posted July 23, 2015 There are some that you put in the tank which burn and apparently clean it, which is what I believe to be codswallop :p 2 Quote Link to comment Share on other sites More sharing options...
stef123 Posted July 23, 2015 Share Posted July 23, 2015 you will need to stick fuel line magnets on too then for that to have an effect 1 Quote Link to comment Share on other sites More sharing options...
MONDEO TXS 2.2 Posted July 23, 2015 Share Posted July 23, 2015 I concur James :) 1 Quote Link to comment Share on other sites More sharing options...
MONDEO TXS 2.2 Posted July 23, 2015 Share Posted July 23, 2015 Exhaust gases drive one side of the turbo & that is why the vanes become carbonised - causing them to stick 2 Quote Link to comment Share on other sites More sharing options...
theredfox Posted July 23, 2015 Share Posted July 23, 2015 blocked the egr on c-max spools up so my quicker in lower gears might try terra clean for injectors nothing wrong with them just to see if it makes any difference as they claim it does paul 1 Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted July 24, 2015 Author Share Posted July 24, 2015 It makes an awesome difference mate. Had it done on my Mondeo, so far I'm averaging 65mpg and the car is more responsive 2 Quote Link to comment Share on other sites More sharing options...
Dales Posted July 26, 2015 Share Posted July 26, 2015 I have heard a few people talk about Terra clean. Most people say the same as you James, it makes a big difference., How does this stuff actually work. can it be used on both petrol and diesel cars ?. I have also heard though that Ford do not recommend using products like this on your car. 1 Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted July 26, 2015 Author Share Posted July 26, 2015 Ford don't like it because it prevents egr and dpf failure which means they loose out on charging a lot for a small part... It works on petrol and diesel and basically it's a charged fuel, the charged particles travel through the hit side of engine, through injectors so the combustion, the exhaust are all cleaned out. The charged particles basically attract the carbon and pull it out so the carbon buildup breaks down, that's why more often than not a load of coke is left behind the exhaust pipe as it works. Now the injectors are clean they spray more efficiently, increasing engine performance. The car can breathe better because the exhaust is clear, the standard carbon buildup around the egr is broken down so it works better and the dpf is part cleared if not almost completely because the carbon had been broken up and thrown out too. 3 Quote Link to comment Share on other sites More sharing options...
MONDEO TXS 2.2 Posted July 26, 2015 Share Posted July 26, 2015 Remember that Terraclean is more about preventative maintenance than ''fixing'' issues - sourced from their website 4 Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted July 26, 2015 Author Share Posted July 26, 2015 Couldn't agree more. I plan on getting every used car I buy in the future the terraclean service, it makes the car work less and reduces the risk. The advice is to use it yearly for best results. 1 Quote Link to comment Share on other sites More sharing options...

MONDEO TXS 2.2 Posted July 26, 2015 Share Posted July 26, 2015 www.oilem.com gives good advice regarding E.G.R.V.'s & D.P.F. issues & other fuel /oil related info - essential reading I think 1 Quote Link to comment Share on other sites More sharing options...
Dales Posted July 26, 2015 Share Posted July 26, 2015 Just bought a Mondeo 2.2 Titanium x yesterday. the guy I bought it off took the egr off, although he gave it to me in case I want to put it back on. Think I might look into getting this done on the car. I take it it will still benefit my car even though the egr has been taken off, Still a bit warey of putting it through my wee Focus ST though lol. 3 Quote Link to comment Share on other sites More sharing options...
MONDEO TXS 2.2 Posted July 26, 2015 Share Posted July 26, 2015 I wonder why he took it off instead of simply blanking it ? 2 Quote Link to comment Share on other sites More sharing options...
Dales Posted July 26, 2015 Share Posted July 26, 2015 Not sure Mark. Car still runs fine. got to give it maybe 4 or 5 seconds once you start it to idle right, but my mates car also did this. Wont do any damage to the car with it being off will it ? The guy also had a decat pipe which he didn't get round to fitting which he also gave me. The guy was planning on a re map also. but according to him he preferred rear wheel drive cars. but in his defence he did have the car advertised for sale or exchange for a quick rear wheel drive car. 2 Quote Link to comment Share on other sites More sharing options...
MONDEO TXS 2.2 Posted July 26, 2015 Share Posted July 26, 2015 I bypassed the E.G.R.V. on my Mondeo ST TDCi without any issues - so I doubt it'll do any damage 3 Quote Link to comment Share on other sites More sharing options...
MONDEO TXS 2.2 Posted July 26, 2015 Share Posted July 26, 2015 It'll have a DPF - not a cat - so not sure about the decat pipe ? 2 Quote Link to comment Share on other sites More sharing options...
MONDEO TXS 2.2 Posted July 26, 2015 Share Posted July 26, 2015 Going back to James's original question - Archoil make very good EGRV & Turbo cleaning products that do work post combustion process 2 Quote Link to comment Share on other sites More sharing options...
