hi all.

yesterday I took the plunge and had the engine cleaned with nitrogen put into the air intake.

fantastic the emissions are now a third of what they were and the car has so much more pull is quitter and smother.
have gained about 15 hp I think was wondering if any one else has had this done 

[Shackeng]

Hmmm, sounds too good to be true, but then I am just an old cynic.

where did you get that done and at what cost....if that aint a rude question..

If it's gained 15hp, then there will be a line of oof'ers and every other car owning person there.

HP costs money and a 15hp gain. I'm with shakeng on this.

[jacko]

that is only 15 hp regained of its 150hp that it has lost over 100 k.

it was £99.00 worth every penny a marked difference in performance

Sounds very dodgy, most of the air pulled into the intake under normal running is Nitrogen anyway.

If its done any sort of decoke then you could achieve the same with a good run on decent fuel or even by using the small breather to suck water in at revs.

Just looked, its Hydrogen not Nitrogen so its simply increasing the cylinder temps, that's real easy to achieve by normal means

Ive heard fish fart, and seen the bubbles. 

[Diamond Black Geezer]

I currently run my engine on 78% nitrogen through the intakes.

This engine cleaning system was used by Ed China on a recent repeat of Wheeler Dealers. It did give better results, although I guess there are other cheaper and easier ways to get the same results.

You'll need to sell the cow first.

If its raising cylinder temps (hydrogen is likely to do that but there will still need to be oxygen present!) then deposits will get burnt off, if your doing lots of short journeys then yes you may notice a difference.

But you could do the same by blanking the EGR and going for an hours drive.....

Or small quantities of water into the inlet is pretty good at steam cleaning the internals!

But it wont clean the inlet, may clean the cat out a bit with the raised exhaust temps (but again a good drive with EGR blanked will do the same)

Thanks. 

Almost sounds like a DPF re-gen cycle, but for the combustion area? 

Raise the temp to burn off the crap, so worth it more on diesels than petrol?

Mr DTM. You have looked into the cylinders/head of the Silver Bullet's probably more times than you care to remember .  Any sign of enough carbon deposits to cause power loss, despite its 230k miles ?

Unless both the engine and the management system are utterly oppsed, there won't be any. The days of coked-up valves and heavy deposits on pistons are long gone.


Squirting snake oil into the inlet tract is the same old Wallet Overthickness Adjustment that it always was.
