Ecopra Fuel Saver

Ecopra: Frequently Asked Questions

Ecopra ~ More miles ~ Less pollution


What is a Comburator?

A comburator is a device used to improve combustion. The earliest known use of a comburator was over 2000 years ago by the Chinese. During the Han dynasty they employed a method of improving the burning of oil in ancient bronze lamp technology. In 1821 d'Orry, Méry et De Corneille patented a similar system for improving the light and reducing pollution from burning candles, calling it a Fumicomburator.

What are the fuel savings and advantages using the ECOPRA comburator?

Most users report economies from 10 to 15% in fuel consumption. There are cases of higher results normally in older cars or using an electronic chip device in electronic fuel injected cars. The ECOPRA device reduces fuel consumption by aiding the carbon based fuel to burn more completely and efficiently. It also helps to clean carbon deposits inside your engine. So, you save fuel, money and help to save the environment.

It uses so little water. How can it work?

The comburator charges a part of the air entering the engine combustion chambers with an unstable air with a high relative humidity, this is not the same as droplets of water as in mist or rain, but as nano particles of H2O, a tiny volume of water is sufficient to achieve this, though the actual water usage will vary according to engine size performance and driving conditions. In damp conditions water usage will usually be observed to reduce.

Will the system improve my performance?

Yes, humid air in an internal combustion engine will assist in cleaning the internal parts as the engine runs. It will increase the torque and reduces the hydrocarbon pollutants currently being released into the air through your exhaust. This makes your vehicle run smoother, quieter and more efficiently than before. You may have previously noticed that your car runs better in fogy or rainy conditions.

Does the system cause rust or corrosion?

No. The combustion temperature in your engine is very high, usually around 1000 deg centigrade, and at pressures exceeding 1000 PSI the moisture which is just Hydrogen and Oxygen is burned instantly and completely.

Does it work with Diesel, Petrol or GPL vehicles?

Yes, the ECOPRA fuel saver works with all vehicles with internal combustion engines.

Does it cause any short or long term harm to my engine?

No, ECOPRA comburator does not cause any damage to the engine, it is not a water injection system and as such no excess water is present. it is impossible for the oil layer on the cylinder wall to be diluted or for water to enter the oil reservoir of the engine.

What type of routine maintenance is involved?

Usually none other than filling the water tank with distilled or rain water as needed. in rare cases if the air inlet becomes blocked it may be necessary to remove the evaporator unit and clean it with hot water and detergent. The catalyser and the evaporator do not require any maintenance if clean distilled water is used.

Will the water in the unit freeze in winter?

It is possible, though usually only in extreme conditions, insulating the installation with a high temperature insulation material and mounting the water tank inside the vehicle and insulating it will help if you live in an area subject to harsh winter conditions. 10 to 20% of glycol may be added to the water in the tank, during extreme periods.

What if I do not use distilled water?

Distilled water is basically pure water. Other types of water like tap water, mineral water, pond water, sea water,will work but they will also quickly cause the unit to block with salts or other contaminants, certain chemicals including acids can damage the catalyser, though this can be easily replaced it is an unnecessary cost.

Is there any kind of warranty?

Yes, the Device carries a 1 year warranty for manufacturing defects, though faults occurring due to bad installation are not covered.

Can the ECOPRA fuel saver be used on a power generator?

Yes, it can work with any internal combustion engine, though where there is not sufficient suction on the air inlet an alternative will have to be found this may be the force of a cooling fan for example.

What is the product life?

The life of the evaporator is almost indefinite as long as it it used correctly and no physical damage is done to it, the catalyser may be replaced after 70,000 kilometres or about 50,000 miles.

Do you have a reseller distribution program?

Yes, if you are interested in becoming a fitter or reseller please contact us by e-mail to

Why is the ECOPRA comburator relatively expensive?

Because it is manufactured with high quality thick gauge stainless steel in the ECOPRA manufacturing facility in Europe, production costs are higher than cheaply manufactured goods coming generally from countries where pay and conditions are unacceptably low. Ecolotec has a policy of sourcing goods from ecologically and socially responsible manufacturers. The ECOPRA fuel saver can be easily removed and refitted to a different vehicle, and will provide years of service, justifying the initial investment many times over.

Can I use a larger model in my car?

There is no point, the ECOPRA units are correctly sized for the engine capacities recommended.

Can I use any kind of water?

It is recommended that you use distilled or de-ionised water but you can use tap water for short periods if it does contain too much iron or limestone, continued use will inevitably clog the evaporator.

How often do I have to check the water level in the tank?

This depends on engine size and tank capacity but about every 500 kilometres or 300 miles on a 1 litre tank used with a 2 litre engine vehicle.

Will installing an ECOPRA comburator void my vehicle warranty?

No. It is an add-on device that can be easily removed. Since you are not modifying the engine fuel tank or ECU computer it does not void your warranty.

Where can I install the evaporator?

The evaporator is normally attached to the exhaust pipe as it is at the lowest point on the vehicle in relation to the water tank which is usually mounted in the boot or at floor level. A height difference is required for the automatic level control of the evaporator. The heat provided by the exhaust gasses also help effective humidification, though excessive heat is not required as with certain other devices.

How much would it cost me to have a mechanic install the device?

Installation of the ecopra device on your vehicle can be easily done by any good mechanic, or by yourself. Mechanics normally like the idea and the installation instructions are easy to follow. Installation cost depends on your vehicle and the hourly rate of your mechanic. However we can estimate your installation will generally take between 1,5 hours up to 2 hours.
