Hallo,
I keep on reading about the development of all kinds of HHO cells...
Has anyone fitted a HHO generator on TD4 engine?


On top of that my TD4 automatic gear box has a "spider" tuning box installed...

Can you share real experience?...

its all  When I die, I want to go peacefully like my Grandfather did, in his sleep -- not screaming, like the passengers in his car

it's all what?
There are documented installations with up to 50% fuel economy...
I have seen such systems installed on many German diesel cars, but have not come accross any Freelander TD4 engines...
That's why i posted the question to the members...

Hydrogen generation can be a can of worms.
Firstly no-one seems to take into account the amount of electricity that is used in splitting the water to start off with. Ever seen what a runaway generator looks like, lots of molten plastic, hope it's adequately fused

But more importantly can you imagine the insurance companies response when you declare it on the renewal form - oh I've just fitted a bomb under the bonnet, connected directly to the engine, and it's not CE certified, so the whole car certification is up the spout.. Yes sir of course it will explode during a front end collision - hydrogen makes petrol look tame when a spark is added.

Probably not for me then. But good luck.
I have "helped" my brother fit one to an old non-turbo Peugeot diesel, he was V.happy with the performance increase, felt it helped with fuel economy but has never measured it, was less than happy when it melted again - he is now working on version 3. Tangiers Orange - gone, missing her

The only plastic thing i see in the installations is the water tank and the tubes...the cell it self is steel....may be we speak of different systems...

Differing from propane and methane systems the Brawn gas generator is NOT a bomb!!!! This is a common delusion, by the way...

Yes sir of course it will explode during a front end collision - hydrogen makes petrol look tame when a spark is added.

[i]why should it explode...the generator generates less then 2200ml/60sec=~37ml of gas per second....

Let's clarify... I am not a seller or manufacturer of these systems!!!!
I am just a owner of Freelander 2 2008 that consumes 10l/100km average and I am trying to cut it down effectively...I have seen a lot of HHO systems installed on different cars but not on one like mine, that's why i started the topic...

This is fitted to a Peugeot near you as fitted by a "Mental Nurse" of my aquaintance


When it comes to energy levels H2 has around 3 times that of petrol weight for weight.
Even small amounts go bang spectactularily, some of the difficulties are:
Detection - colourless and odourles,
Burns without visible flame,
Tiny molecules are brilliant escapologists,
Controlling the gas generation -those I have seen tend to be on/off devices, so generate too much on tickover, and not enough at full throttle, gas is still liberated after power is removed as it dissolves out of the liquid.

I have to design control systems for hydrogen (and other far nastier chemicals) for a living, and I do not believe that the systems I have seen available on the internet would pass a CE certification process.
Land Rover and others would definately stand shoulder to shoulder with the petrol companies, HM revenue, and the insurance companies if something went wrong.

Don't get me wrong, there might well be an improvement in performance when using HHO, the owner of the unit above swears by/at it.. It's just the safety issue that worries me.
Seriously though
Good luck with the search - and install if it comes to that Tangiers Orange - gone, missing her

Don't get me wrong...but "this thing" on the photo looks really dangerous
What i am reading is some developments like these:
http://hydroxsystems.com/
http://www.hho-bulgaria.com/
http://www.hhoplus-bulgaria.com/
http://www.safehho.com/
I found plenty of systems on ebay, but they lack proper electronic control (mapping) units for our Freelanders cpu...
I don't know if there is CE certification , and personally I don't really care...It's only for insurance purposes of elements that do alter engine architecture...As I told you I have a diesel spider tuning box attached and the insurance is NOT affected by it's presence in any way...

I am very keen on this idea, especially when a I saw a real 40% fuel reduction on a VW Passat...
I ask everybody with experience to share it...

why buy a land rover if you want performance and efficiency, the vehicle at standard is perfectly adequate if you want more power and efficiency get a remap dont mess around with hho cell kits... Potential gains don't outweigh the dangers and costs of doing it anyway...  When I die, I want to go peacefully like my Grandfather did, in his sleep -- not screaming, like the passengers in his car

Sorry I couldn't read the first three sites as my Bulgarian is non-existant.
The forth site did waffle on about coated titanium electrodes that don't corrode.

I work for a company that has spent large sums of money in the last 10 years trying to perfect such a thing for AC applications, DC destroys titaniam even more rapidly, S.Steel doesn't last long either, and produces chromium into the electrolyte - not good. So would take any claims with a pinch of salt.

If you are going to install one, just take care that the system is safe - unlike the one in my photo.

I personally wouldn't, then again I haven't bothered to chip my engine this time, as the fine control off-road and in bad weather is far more important than outright speed.

In the UK chipping the engine without informing the insurance company will invalidate the insurance, let alone, fitting an aftermarket fuel system. This is probably why such systems are less well known in the UK. Tangiers Orange - gone, missing her

I don't believe a 10l/100km is a reasonable fuel consumption...as the LR stated 8.5l/100km in the official brochure...
As I wrote before I have my car tuned with
http://www.dieseltuning.co.uk/landrover-fr...uning.html
which was supposed to return increased power and torque with 10% fuel economy...
None of the above is true , alas....
And once they sold the box didn't bother to answer any more emails...
At least Brawn gas was discovered by Bulgarian, so plenty of developments based on his studies take place here...but none fitted to Freelander

let us know how you get on would be interesting to hear about your project  When I die, I want to go peacefully like my Grandfather did, in his sleep -- not screaming, like the passengers in his car
