Conclusions of the Prodrive Laboratory Tests:

"The addition of the Ecotek CB-26P device to these three vehicles saw a reduction in both fuel consumption and CO2 emissions in all cases.

The Fuel consumption reduction is maybe not as apparent under these test conditions with a reduction in the order of 1 to 1.5% on each vehicle, however it does confirm that the unit is of benefit, even under tight test procedures. In general open road driving it is quite conceivable that these gains may be significantly increased.

The reduction of CO2 is also a significant side effect, although the reduction is again of the order of 1 to 1.5%, any reduction of CO2 emissions should be regarded as beneficial. The CO2 reduction is most likely due to the dilution effect of introducing un-metered air into the inlet manifold but for whatever the reason, the result should be regarded as worthwhile.

This introduction of un-metered air would normally give rise to the expectation that the NOx emissions would increase. Typically, additional combustive oxygen in the mixture, which has not been quantified by the cars engine management system, will increase the combustion temperature, due to a slightly leaner mixture, and subsequently increase the production of oxides of nitrogen (NOx), a linking of nitrogen to the excess oxygen in the combustion process.

Surprisingly, save for a small increase on the Fiesta, the NOx emissions were the same, if not better with the Ecotek device fitted. Given the overall scheme of the tests this can be seen as a benefit, as it would have been expected by the apparent nature of operation of the device, that these emissions would have significantly increased. This has turned out not to be the case; giving rise to the potential likelihood of genuine combustion improvements being generated by the Ecotek CB-26P device."

These are actual pictures of one of the test cars during the laboratory tests conducted by Ecotek at Prodrive Laboratories in Milton Keynes. The test equipment is regarded as state of the art and is used to confirm manufacturers emission and consumption figures for the DVLA and the UK Government under Statutory Provisions relating to Vehicle Excise.

The combination of the Datron and Prodrive tests confirm that the device improves performance, emissions and economy - whilst the improvements in economy and emissions are significant but not dramatic, it should be noted that the cars selected are renown for being both fuel and emission efficient - it is also important to recognise that all the test results are averages of several or many tests and optimum values are thus discounted.

In the event these tests unequivocally confirm that significant performance gains can be combined with improvements in economy and emissions by fitting the Ecotek CB-26P device: To summarise the conclusions of each recent test:

Datron: "It is clearly established by an analysis of the data that the device improved the performance of all three cars during the test."

Prodrive: "The addition of the Ecotek CB-26P device to these three vehicles saw a reduction in both fuel consumption and CO2 emissions in all cases".

Given that these tests were undertaken on the same cars it would appear that significant performance gains can be combined with improvements in emissions and economy.
