Engine Decarbonising.....

[jimbobsimmonds]

Don't know how many other people see the new Wheeler Dealers with the poorly Jag which is failing it's MoT emissions...

Anyhow for those that you that didn't the 4.0L V8 was throwing out IIRC 3 times the HC of the fail limit so the ever so tall Ed brought out another one of his amazing tools, an "Engine Decarboniser". This uses (apparently...) ultra refined fuel with certain additives mixed in to clean the entire system. The car is left to run off this fuel for an hour at 1200rpm until the cleaning is complete. Ed sticks the Jag back ont the machine and the CO is halved and HCs brought massively down... and he says this is all for £80... Great.

Now, does anybody know of any reputable companies providing this and does anybody have any experiend of this actually working?

Seems better than a bit of snake oil bought in the garage but still... Seems too good to be true...

I saw that episode too - I'd also be interested to hear from anybody.

I'm very interested in the workings of the process - although I guess that's a 'trade secret'.

[Wycombe83]

I'm sure a similar process has been mentioned in Car Mechanics mag over the years.

[jimbobsimmonds]

Anyone with Sky+ got it recorded to see the company that does it, i assume they will be in the credits. Cant find much on google...

[gtidriver]

Here you go. Terraclean fuel system de carbonisers.

[redgriff500]

If you want to de carbonise the head - squirt water in the intake - a bit of care is required but I've run DIY water injection for years with great results.

The company name was covered with tape on the two canisters he used so perhaps the company would not play ball with free kit!

I had a treatment done on my previous Ariel Atom which had a very rich fuel map on its Rover K-series engine, it made a massive different to the point I could start the car and it would idle without need a bit of help from the throttle pedal when cold.

Didn't use a machine like that but some stuff that must have been closely related to mustard gas, I think it was called Fisk or something like that

When I had an MGF, i took it to a. Rolling road. There was a problem with idling ( later diagnosed as a badly fitting throttle body)

Before the rolling road and in an attempt to clear the problem they sprayed some sort of aerosol into the air inlet. It made the car cough and splutter, then it ran fine. The guy said it was Vicks Sinex for cars.

Would this be something similar?

[Dogwatch]

I suppose a good blat in 3rd gear might do it?

[twink]

That seems rather a lot just for a bit of an engine clean. I can see it being a good idea though with it not stressing the engine, just idling pretty much. On my cars the only engine decoking I've done is a can of 10k Boost in the inlet, a shot of Redex in a nearly empty tank then get it hot and screw the tits off it for a bit. I had a diesel Vectra with straight through exhausts and no cat which only just registered on the MOT emissions test at full throttle after that.

First time i'd seen it for a petrol iy's been about for a while on diesel cars, you run the engine off a cleaner in a can for 30 mins or so.
Thought it was interesting

Won't it just be redex. In the olden days (when you could fix a car with a hammer) it was standard to run redex thorugh your engine if it was running a bit crap.

[Roadrunner23]

A good old Italian tune up is what I do.

[Mr MXT]

I wondered how much of the reduced emissions was down to a cold start on the first test and a nice warm engine and cat on the second?

And that's exactly what I thought when Ed said words to the effect of "too high HC/emissions fail" - try re-testing when it's a bit hotter and the choke's (ok, cold start enrichment) not on!

[laam999]

at the risk of sounding like an idiot, if I put a fairly large amount of redex into my nearly empty tank and let it run for a while this will help clean the engine and reduce emissions? my project cars gets its mot test next week and at the cost of a few bottles of redex id give this a go, my worry is it may burn too hot and potentially damage the engine, any tips would be great.

thanks

Damn you - just wasted 5mins and 30secs of my life watching that utter load of tosh.

Terraclean - columbally fractionalized electrically charged terraclean molecules which vapourises aliphatic carbon deposits.

I call bu*****t bingo.

Get the head off and give it a decoke... Just like Grandad did!
