[@kenlarman4252]

Good honest unbiased opinion Jimmy 👍 I’ve always thought the only way to clean the oily carbon build up is to disassemble the inlet components and clean them manually, anything else is just a temporary fix which will still leave a surface which will attract the buildup to happen again quicker, obviously the cost involved in this method is expensive but if you can do it yourself it’s the best route to go.

[@ORileysAutos]

Definitely the best way. I do use the chemicals to do a Carbon Clean. Even that is limited but has enough success to free up stuck EGR and turbo vanes

It removes money from your wallet at a far higher rate than removing carbon from your engine.

[@wesleyderwael]

I totally agree, I have done tests on 5 cars, with HHO for 1 to 2 hours per car. Diesel and petrol. Did a check of intake, egr, combustion chambers, spark plugs and dpf and dyno runs before and after. No changes at all! On a 2 liter diesel it compensates for 1% of the fuel necessary for running on idle. And it was a heavy 3kW HHO generator, producing way more bubbles than the one shown here. Total snake oil marketing! Invest in good quality additives like WYNNS, built for the purpose you need!

[@leecoulton4236]

I have a hhc machine not that one but all do the same thing. They sell them as they clean inlet valves manifold etc. Witch is bull. But iv had great success with it on diesels that have failed emissions test. I pulled head of my van after a clean +6k and was amazed how clean it was.

[@mrfishbulb7187]

Wouldn't loosening carbon deposits from the intake side eventually make it's way through the engine and clog up the DPF?

[@JustMe-Dude]

I have seen videos where, during the cleaning little chunks of carbon were coming out of the exhaust pipe onto the ground. so yes, I would imagine those chunks go straight to the DPF. if a lot of them build up and it tries to region on the road, it can cook it into place. (update) so there's no confusion the carbon chunks coming out of the tailpipe were on a gas engine without a catalytic converter to stop the debris. A DPF is designed to stop debris.....

[@anonymousdcal]

not if you hoover them out before turning on the engine

even better turn off egr and dpf and remove dpf core then recycle better mpg performance and less maintenance!

[@nathanreid2974]

that should be done at some RPM, probibly 2000 to 2500rmp. I know you said other carbon companies do it at idle, but some do it at RPM. The intake i gues, will suck the hydrogen in and combust it more as well.

The hho doesn't do anything before it gets burnt I had a customer that ran a hydrogen generator on a old di transit to get a few more miles to the gallon a year later we had the head off to do the gasket and the pistons and combustion chambers were spotless from the hho turning back to water and basically washing the inside but it will only work in combustion chambers

[@graemewhitfield2940]

The only way to remove carbon build up off the intake valves etc is a wall nut blaster. It just means the inlet manifold needs to be removed. It’s amazing how much power is taken away from an engine when it is suffering from carbon build up. Carb cleaner and small brushes work well on other parts like the throttle body etc.

[@mauriziogiasan4411]

thanks master .but the hydrogen if I'm not mistaken goes to clean the hot part of the engine and not the suction part . by hot part I mean valves .combustion chamber .exhaust manifold .turbine. etc

Good point. Isn't the whole premise that the burning of the hydrogen captures a carbon atom in the process? I'm no scientist of course.

These are regularly advertised to clean intake manifold and EGR clearly that isn't true. Maybe I'll remove the head and inspect the vales and cylinders 😉😅

​​@@ORileysAutoshat's the problem with it mate, too many people, including companies that sell the machines, will claim they clean intake systems when it's just not possible.

I sell it as an add on to a dpf clean as a preventative measure and have never had a negative report from a customer.

[@sull5307]

@@ssss-df5qz burning hydrogen will get you a water :) Water is not good for taking a carbon deposite (if at all). Update: but, that reaction generates a ton of heat, so I guess that is the purpose. Or it could be that it reacts with carbon trough reduction process forming CxHx compounds which are volatile and therefore easily removed.

I have been involved in electrolysis (which is all this machine is) for 15 years and that is why I have never done this to any vehicles because hydrogen alone will not remove carbon deposits. I would say though that in order to achieve some degree of success the engine needs to be running on hydrogen only...

[@LucasVWGolfR]

Interesting video Jimmy. I have always been skeptical about these machines and if they do anything. Ive manually cleaned the inlet manifold on my Audi SQ5 TDI twice in the 50,000miles ive had it and have used various products (petrol, brake cleaner, degreaser etc) to see what is most effective, but found throttle body and carburettor cleaner to work the best. Apparently oven cleaner also works well but I havent tried it yet. Regular manual cleaning, plus fitting a good quality Mann & Hummel catch can is the only way to keep ontop of the carbon buildup in my experience. Also using the best quality diesel and giving the car regular heavy throttle applications to reduce the EGR being open as much.

[@simoncsaby3073]

best and most honest review, carbon cleaning it's just a scam which tuners advertising

[@gaj1612]

Pretty much as you said Jimmy, it won't do anything at all for the intake side of the engine as the hydrogen needs to combust before it has any sort of effect. I've always had good results from hho carbon cleaning but it us offered as preventative maintenance. It's very effective at freeing off sticking turbo veins. I offer a chemical based intake clean as well as the hydrogen which obviously has a greater effect on intake systems and egr valves.

[@v6si]

Always enjoy your videos but you’ve stuck your head above the parapet with this one Jimmy! If you solve this controversy then there’s probably a peace prize in it for you. In my humble experience of owning turbo diesel cars over the last 20 years, then buying the better diesel definitely slows down the build-up in the intake in the first place. Either that or buying 2EHN and putting it in the tank with regular city diesel (which amounts to the same thing). In both cases there the combustion is much more complete and so there is less to come back via the EGR. Appreciate that’s of no help when you have a customer with a clogged intake, but as a preventative it seems to work for me. Also the Italian tune up (i.e. ragging its arse off at least once a week when warm also seems to make it run smoother afterwards). I’ve been told by a few people (i.e. I don't know for sure) that if I buy the cheapest / simplest water injection kit (there are a few kits which are less than 300) then that water mist which gets sucked through the intake after the MAF will (over a period of time) wash away most of the carbon sludge in the intake and also steam clean the back of the valves. Could one of those maybe be a future video? Where you fit one of those to one of the fleet and update with findings. That could be a great series of videos. It might even turn into a lucrative side line in fitting them to your subscriber’s cars…

After reading the comments, a further trial of this machine on another vehicle should be done. Next time remove an injector or glow plug for a before and after inspection of a cylinder with a borescope. Some of the pro-hydrogen commentors make sense that its a 'hot side' only process, its worth another trial whilst you still have the machine. Makes interesting content too.

[@ORileysAutos]

I've never seen anyone say I'd like my cylinders carbon cleaned. Cylinders cleaned themselves as they are "hot" Everyone who gets a Carbon Clean done is looking to clean the intake manifold and or the EGR valve and turbo. For me this has proved enough that its a waste of time and money and not something I'd feel happy charging a customer for.

[@JustMe-Dude]

I think the biggest point here is that the launch cleaner probably does the same thing on the cylinder heads and turbo as this hydrogen cleaner claims to do. I think when Jimmy runs this through the intake, you would probably see very similar results in the combustion chamber, so there really is no point in much additional testing.

[@pdonneky]

Hi Jimmy, Because we like, respect you, and your very valuable input to the motor industry, I will do a write up on this machine for you in a few days that i hope will give you and the viewers a better understanding of what its actually designed to do and not what peoples claims it does, the industry was badly damaged by amateurs making bold claims on facebook etc, showing off little green boxes that was modified hydrogen gas welders, re badged by a company called carbon kings etc etc, The machine you showed is not a one off, we have several of them, lets meet up soon for lunch and a catch up asap, thanks, Paul @ CD

[@JustMe-Dude]

not so much of a question of what a HH will do and how, but why pay that much to clean half the system when a chem clean can clean the complete system inlet to exhaust better, and without putting chunks of carbon in to the DPF inlet. (or CAT on gas)

@@pdonneky unless you're using a borescope into the front end of the DPF, how would you see the little chunks of carbon stuck in the honeycomb? running an HHO without a CAT on a gas engine, you would see debris coming out the tailpipe. plenty of videos out there showing this, as if it was a good thing and proof that it works, but does not take into account what happens at the DPF.

You have to rev the engine up every 5 to 10 minutes jimmy to agitate and remove loose and vaporised particles so that the gas starts to get the next layer. You should have checked the valves and injector tips and piston crowns and the hot side for a before and after shot, the EGR won’t move if you don’t rev it but a engine carbon clean is a preventative procedure not a cure as it would have removed a soot buildup off the EGR but not the sticky marmite, same on the intake side, only a preventative.

Because your analysing a part that doesn’t get cleaned by a carbon clean, your not doing it right, rev it 10 times at 3 to 4 thousand revs every 5 to 10 minutes, it needs at least 1 hour and then take it out for a test drive for 20 minutes pushing it in low gears and get another 30% of the crap out, you done it like someone who has come over the channel in a dingy with a £200 eBay special and done the snake oil brigade proud, but if you’re going to rip the back out off the process at least do it right. Then get it analysed at your mates mot station with a exhaust gas analyser, then give everyone your opinion buddy.

Did you rev the engine while letting the machine run? For the best results you want to rev it up and down every 5-10mins. Helps clear the carbon deposits in through the hot side of the engine👌🏽 These machine clean the hot side of the engine 👍🏽 most noticeable differences before and after are increase in responsiveness and smoothness and quietness of the engine. 👍🏽 Been doing carbon cleaning for around 4 years now my results have shown anything over 100k benefits most from Atleast a 90min clean with reving every 5-10mins. The carbon cleaning processes are more of a maintenance then a full clean getting it done annually is best for keeping the carbon deposits down in the engine👍🏽 Doesn’t clean the egr or intake manifold only the hot side so combustion chamber- exhaust valves and hot side turbo and out the exhaust. Many say it will help clean the DPF but actually blocks it with the soot from the engine. When I do DPF cleaning I recommend getting the carbon cleaning done before the DPF clean so that the soot created from the cleaning is cleaned out 👌🏽👍🏽
