Emission Test Results

Here at CGON Ltd we prove what we say - our recent Emissions Analytics results are just outstanding!

Every vehicle tested has special equipment attached and is physically driven around Bruntingthorpe Testing Ground at a variety of speeds and conditions. As the vehicle is subjected to variable road conditions, air resistance and gradients, these tests give a more realistic set of results.

Below are the results of our NOX tests that were carried out on a variety of diesel and petrol vehicles.

The end result of vehicle usage are the pollutants exhaled, they are damaging to both our environment and to our health:

Carbon Dioxide (CO2) – This is a non-toxic gas, which has a negative contribution towards the environment. This is a global problem and governments around the world are continuously pursuing policies to reduce CO2 emissions.

Carbon Monoxide (CO) – Produced from an incomplete combustion process of fuel. This gas is hazardous to health; it reduces the ability of blood to carry oxygen, cause of headaches, respiratory problems and at high concentration; death.

Hydrocarbons (HC) – HCs are emitted from the exhaust as unburnt fuel and as evaporation from the fuel tank and from the nozzle at point of filling up. HCs reacts with Oxides of Nitrogen (NOx) in sunlight which produces photochemical oxidants and low level Ozone, causing breathing problems and increased symptoms in those with asthma.

Oxides of Nitrogen (NOx) – NOx emissions are produced in the combustion process. HCs reacts with NOx in sunlight which produces low level OZone; this can cause inflammation of the airways reduced lung function which can trigger asthma and can contribute to the formation of Particulate Matter (PM).

Particulate Matter (PM) – This is partially burnt fuel which is mainly associated with Diesel Engines. The molecules are formed by the reaction to the other pollutant gases. PMs are small particles that make their way in to deep tissue causing respiratory and cardiovascular complaints.

Particulate Number (PN) – Just like PMs, Particulate Number is a partially burnt fuel associated with Diesel Engines. PNs are molecules that are so small they can only be seen under a powerful microscope. The molecules make their way into the body through the skin causing; irregular heartbeats, nonfatal heart attacks, decreased lung function and increased respiratory symptoms and even premature death in some cases. The ezero1 has been proven to reduce these harmful emissions. Vehicles of all ages have been tested both on and off road; the results are outstanding!

Future Testing

Our future testing will look further into the effect of the CGON system on 'Diesel Particulate Emissions' and the effect on 'DPF filters'. We have some very encouraging in house test results which indicate as much as a 70-80% reduction in diesel particulates and a significant enhancement to the DPF systems fitted to most modern diesel vehicles today. But we have to independently test and verify our findings, so watch this space!
