Your HHO Questions Answered

Q: What exactly is HHO gas?


A: HHO, (also known as Brown's Gas or Hydroxy,oxyhydrogen,Hydroxy,H2/O2) is produced when water is separated into 2 parts of Hydrogen and 1 part Oxygen (2 Hydrogen 1 Oxygen), by using dc electricity from the vehicles electrical system

Q: If this technology is so good why are the manufacturers not using it?

A: they are just google CREO project !


 Q: Why are there so many reports HHO/Hydrogen on demand does not work ?





A: The basic science behind the technology has been proven for many years (refer to benefits pages for the science facts) the problems as with all new technologies are numerous, and you need to remember the Wright brothers first aeroplane was not an instant succes, evolutions from the basic concept has taken many years,and not everyone gets it right first time. We therefore apologise on behalf of the pioneers that have taken the industry to this stage, however the technology has now evolved and been tried and tested to the extent where it is suitable and safe to operate in the majority of modern engines,but not all, providing significant benefits including a solution for emission problems, optimisation and improvements are and will be ongoing





The Top 10 reasons for HHO/HOD systems NOT working properly are:





1) Incorrect or poor fitting including poor quality wiring (inadequate rating and connections) and loss of gas through system leaks,and electrolyte leaks





2) Poor Quality Cell design and thermal run off (overheating) producing steam and NOT Oxyhydrogen/Good quality HHO/HOD/H2/O2.





NB. if you see a system resembling a coffee jar or sandwich box IT IS NOT SUITABLE for transport systems and is highly likely to be dangerous !





3) Induction into the wrong place





4) Incorrect engine timing for REVISED COMBUSTION SPEED





5) Incorrect levels of amps/gas for the required load and drive cycle





6) Incorrect O2 /Lambda sensor adjustment (front and rear) (in some cases there is none) which will cause the vehicle to overfuel





7) Incorrect baseline comparison and drive cycle of pre and post installation





8) Amps running too high/Low/ ie regulation of amperage





9) Incorrect Ventilation/cooling





10) Injection timing /multi cycle injection timing combusting the gas before piston hits TDC, causing pre combustion










This is not a definitive list but are some of the main causes of problems historically throughout the industry






Q: How does a HHO unit work?


A: In the HHO unit plates of 316l stainless steel and or a titanium compound are immersed in water. When electricity is introduced to one plate it travels through the water to the opposite plate. In doing so the water breaks down into its component parts which are hydrogen and oxygen (HHO) which when introduced to the engine causes more complete combustion.



Q: What size of engine does it work on?


A: We have a range of products suitable for different cells for engine sizes and drive cycles



Q: What type of fuel can be converted?


A: It has proved successful on petrol, diesel and LPG and NGV. We are accruing more information on LPG converted vehicles as we go along. It is clear that mpg improvement and emission reduction is achieved on all these types of fuel.



Q: How long has HHO technology been around?


A: Francois Isaac Rivaz designed in 1806 the De Rivaz engine, the first internal combustion engine, which ran on a hydrogen/oxygen mixture In 1863. HHO technology has been used in vehicles since the 1920’s. In those times the fuel was very crude and the engines consumed a lot of the lubricating oil. This caused the combustion process to be so dirty that it was common to take the spark plugs out regularly, in order to clean the residues off them. The early HHO hydrogen gas generator unit allowed this poor quality of fuel to be burned more completely and improve the combustion process which stopped the plugs from being fouled.



Q: How safe is a HHO unit?


A: A HHO unit is as safe as water as that is where the hydrogen and oxygen is stored. Once HHO gas is released it is immediately consumed by the engine. When the vehicles engine stops the unit stops producing hydrogen. Water is a lot safer than petrol, diesel, hydraulic fluid, brake fluid etc. Also hho is lighter than air and will dissipate upwards if it leaks unlike petrol etc which tends to pool in the lowest places. Our units are designed to the highest safety specification and have a number of built in safety devices. They have been running for over 5 years and installed on 100,s of engines.



Q: How efficient is the HHO combustion process?


A: The results depends on engine size. When this HHO fuel economy unit is used the combustion process improves typically by 10 to 30% because all the fuel is being burned more power is produced from the same quantity of petrol or diesel. This allows the vehicles engine to operate more cleanly, cooler and more efficiently. Our commitment is to a reduction of 15%.



Q: Is it a good idea to convert your vehicles to use HHO power?


A: Yes, by converting vehicles to use HHO power, you will be able to:

1. Improve your vehicles fuel efficiency typically by 10-30% on average and save thousands of pounds on fuel every year
2. Improve efficient burning of fuel and greatly reduce engine clatter and reduce carbon deposits
3. Reduce emissions and discharges and help in the fight against Global Warming
4. Greatly improve your vehicles engine's performance
5. Reduce the vibration and enjoy a smoother engine operation
6. Prolong the life expectancy of your engine and transmission.


Q What impact is their on emissions?




A. We have independently verified and certified emission reductions of Co2 by 50%, particulate matter by up to 85%, and reduced NOX and CO of over 20%. This data is available on request.


Q: Why is More MPG Now Ltd HHO Dry Cell unit the best?


A: The materials used in our HHO unit are the best that can be sourced. The design of the HHO unit overcomes any electrical edge losses that appear to be inherent in inferior designs. Thousands of hours of research have been put in to our HHO unit to produce the best, most efficent, reliable and best value for money product on the market.



Q: What are the additional HHO electronic options for? Why buy an integrated DEFIE?



A side effect of any HHO unit is that the total burn of the fuel reduces the temperature of the exhaust and increases oxygen in the exhaust gases. On modern vehicles the electronics suite, which controls the fuel flow, can mistakenly read the excess oxygen content of the exhaust gases as too lean a mixture and increase the fuel flow in order to correct this lean mixture signal.




Q: Will this HHO unit damage my vehicles engine?


A: Properly installed following our protocol our HHO unit wont harm the vehicles engine in any way. In fact it will clean it and improve its performance and smoothness of power flow, this also benefits the transmission.The hho works best in a lean fuel environment as the hho reduces the temperature of the combustion which protects the engine from valve or piston damage. To ensure best results we recommend a professional installation.



Q: How hard is it to install this HHO unit? Is it transferable?


A: It is not considered difficult to install for an experienced mechanic. In order to get best results we recommend professional installation. The HHO unit can also be transferred to the next vehicle you own. Full instructions are supplied.



Q: Will the HHO unit cause any corrosion in my vehicles engine?


A: No, any water that is produced during the combustion process is in vapour form due to the high temperatures and is merely released through the exhaust.


Q: Is the HHO unit a modification of the car, will it effect manufacturers warranty?

A: The HHO unit isnt a modification, it is a non permenant addition and as such has no effect upon guarantees. In the USA this was established in a court case under the Moss Magnuson Act. This Act stipulates that a dealer cannot void a warranty because a vehicle is fitted with aftermarket parts. In 2003 the European Union brought in further legislation affecting the motor trade hrough the Block Exemption Regulations (BER) which closed loopholes that the warranty companies were using to get out of paying warranties to thier customers. BER states that a warranty company has to prove beyond all reasonable doubt that the after market addition directly caused an engine failure or impairment to the vehicles performance. This in practice neccesitates the commission of an independent automotive engineer to provide burden of proof and the need to go to court. The European Commission have declared that any clause to the contrary in a warranty document would represent 'an unjustified restriction on the consumer'.



Q: How will it effect the performance of the engine?


A: In all of our installations so far we have only found that there are benefits to the engine in as much as smoother combustion, more complete fuel burn and lower exhaust temperatures all benefit the engine. In any event, we are setting up a customer care/ warranty scheme that can give you additional protection and peace of mind to you here - look out for details.



Q: What servicing is required?


A: Merely keep an eye on the water level indicator. A regular check on the quantity of distilled water in the unit at first, to check that the HHO unit is functioning, as it should, In the case of a commercial operation the reservoir will be mounted in plain view and a quick look at the end of the day will indicate if it needs topping up. Our product range is designed to keep maintenance requirements to a minimum. However, regular preventative maintenance will ensure optimum running of the HHO unit assuring the operator of the maximum savings and lowering of emissions for the fleet of vehicles.



Q: What customer support do More MPG Now provide?


A: More Mpg have a 24-hour e-mail and phone line support service. Out of hours calls will be dealt with at the earliest possible time. More MPG now have a commitment to get back to you within 24 hours - please use the contact us function on the site.



Q: Is this HHO unit explosive?


A: In our HHO unit the hydrogen is created as you drive (it is not in a compressed form) and is not stored in the vehicle except as water, which is a lot safer than many of the liquids stored in our vehicles. The system is at atmospheric pressure, if there is a build up the combination a safety valve will release and excess pressue.The system will return the vehicle instantly to pre running conditions should the units fail, so mobility will not be affected in any way.



Q: What if I lose economy after a period of time?


A: We use an onboard monitor that will The answer will be to check that there is enough liquid in the HHO cell and that there is an electrical supply. An onboard meter/display will indicate exactly what energy is being consumed and this will tell at what rate the HHO unit is operating.



Q: What do I do if the HHO unit freezes in the winter?


A: A small amount of denatured alcohol can be added, around 5% will protect to about ten below. The HHO unit wont be harmed by freezing and will simply thaw out once it starts to work.



Q: Does the HHO unit come with a warranty?


A: More MPG offers the best warranty packages around - contact us for details.



Q: Are there any regulatory issues with supplemental hydrogen systems?


These systems are now TUV safety approved, and come with CE certification. We are constantly working to ensure that our product suite as it develops meets all regulatory and safety requirements for vehicles on the road with hydrogen supplementary fuel systems.



Q: What are the issues for Insurance?


A: It is recommended you contact your insurance company to ensure you do not invalidate your vehicle insurance. The salient factors to note are:

- It is an accessory: an add on to the fuel system, it is not an engine modification but a fuel additive / supplement

- It is completely reversible as there are no permenant changes to the vehicles settings or performance

- It is safe as it doesnt store hydrogen but creates it steadily from water stored in a reservoir as the engine is running

- The fuel economy unit operates by giving more complete combustion of the fuel, thus causing the engine to use a smaller amount of fuel for a given performance, resulting in improved fuel economy and a smoother and cooler operation of the engine.

- It does not change the configuration of the engine

- It is not a modification but a non-permenant after market 'add on'

- For DVLA purposes the system can be classed as a dual-fuel like LPG; you need to amend the relavent part of the vehicles owners document

There are several insurance companies/ groups who now offer cover in this area in the market. We will continue to upload relevant information to this page in order to keep you abreast of developments in this area and how to get the best from your HHO fuel economy unit.
