Ecopra for Cars & Vans

The ECOPRA DEVICE on Cars and Small Vans

More miles ~ Less pollution

Fuel saver for cars and vans

Fitting instructions are able to be downloaded HERE but probably, the main consideration will be where to site the water reservoir.

The ECOPRA kit comes with a 5 litre tank as standard but any convenient tank may be adapted for use in your vehicle, for example you may prefer a smaller one. 

Always site the Ecopra air supply tube before the air filter.

The diagram below illustrates the basic positioning of the components, but if desired, the water tank can be placed in any location, including in the engine compartment providing it is situated above the evaporator.
The lower evaporator air entry tube must be open in the forward direction of movement. Its route must pass over the evaporator to avoid water drainage.
If you are in any doubt consult a mechanic, but don’t be put off by negative comments. Most people are unaware of this technology and often confuse it with something else. NO HARM CAN COME TO YOUR ENGINE through fitting an ECOPRA fuel saver.

Carbon Dioxide emissions are reduced in proportion to fuel use. There will naturally be a reduction in CO2 emissions as they are intrinsically linked to fuel economy… 10% less fuel means 10% less CO2.
Nitrous Oxide and particle matter emissions will be significantly reduced in diesel motors and CO (Carbon Monoxide) emissions in petrol driven vehicles can be reduced by up to 80%.
These figures will vary from one vehicle to another depending on a variety of variables such as engine wear, age and type, driving style, load, speed, etc.
We don't believe in making exaggerated claims of efficiency, but a generally reported figure for most vehicles is an 8 to 12% improvement in fuel economy. 
On older vehicles this figure may be significantly greater, particularly in the case of particle emissions on older diesel engines.
Fuel economy can also improve significantly over these averages for earlier petrol engines.

How It Works

The ECOPRA COMBURATOR regulates the air consumed in the combustion process. The advantages of the system are produced by the nano humidification of a percentage of the air required for combustion of the fuel.


The effects of the regulation of the air quality on the combustion process are immediate. The engine becomes quieter and increased torque will be observed. An increase in torque translates to less fuel injected per cycle and less pollution. CO2 will be reduced proportionally and NOx may be reduced by up to 80%.
Particle emissions on diesels will be reduced, and the characteristic black smoke plume sometimes disappears altogether.
Average reported fuel savings are 10%, though this will vary according to engine and fuel, significantly higher figures have been reported on older vehicles.
Engine power will not be changed, but efficiency will be improved.

Operating Principle

The ECOPRA COMBURATOR acts on a percentage of the air entering the combustion cylinders, this air enters the motor by the depression cycle of the pistons and joins the airstream before the air filter. There is no possible contamination as the air filter is designed to remove all undesirable contaminants before it enters the combustion process, this is required not only to protect the motor but the highly sensitive air volume measuring sensors used in todays modern direct injection engines.


The device is manufactured in Europe and is made of stainless steel, it requires no external source of power, is entirely recyclable, and is not fitted to the vehicle in a permanent manner.
It can be easily removed and installed on a different vehicle if required by the owner.
