Your HHO Questions Answered

Q: What exactly is HHO gas?

A: HHO, (also known as Brown's Gas or Hydroxy) 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: 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 mileage

Q: What type of fuel can be converted?

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

Q: How long has HHO technology been around?

A: 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. 

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 20 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 20-30% 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 recorded very sizeable reductions in carbon emissions, with cuts of over 50%.  This data we can share with those customers and partners who choose to work with us under and NDA

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:   A side effect of any HHO unit is that the total burn of the fuel reduces the temperature of the exhaust and leaves some unburned 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: Very glad to say NO to that question, with this 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 of a safety chain means there is very little build up in pressure or heat.

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

A: The answer will be to check that there is enough liquid in the HHO cell and that there is an electrical supply. An ammeter 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 currently sold on an experimental use basis with responsibility for insurance and warranty resting with the purchaser. Regulations are evolving in the EU. 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.
