I first became interested in a device call a Gefarator in the early eighties when I fitted it to my mobile workshop a Leyland Sherpa. It was a dog of a vehicle and carried an USA Autosense Computer costing over £12.000 The constant juddery clutch caused the motherboards to displace demanding frequent visits from the engineers in Bicestor.
Fitting the Gefarator immediately stopped the judder as you now no longer needed to slip the clutch,just let it out.
I became an agent for the device for some years until they stopped being made.
Recently a batch turned up, I acquired the stock having first fitted one to a Honda Coupe I had P/X.
Amazingly it worked and emissions of 0.284 CO% & 114 HCppm dropped to 0.008% & 18ppm. The following day they had dropped almost to zero.
I subsequently fitted the device on my sons 53 plate Skoda Superb 1.9 TDCi it having failed an MOT though not on Smoke readings being FAS1 4.62 K(m-1) 2)3.00 3)1.98 4)1.77 the car having done 185.000mls. As the car was out of tax it was not used until I fitted the Gefarator then ran 1/2mile to the MOT Station where I requested another Smoke test. Although not up to temp(71oC) Test1(Fast Pass) was 0.62K(m).
Our works van a Berlingo non turbo diesel 125000 had one fitted and was driven about 5 miles to another MOT garage and surprised the operator by having an absorption coefficient of just 0.70 1/m then automatically stopped as it had passed first time. Something the operator says he had never achieved on that type of vehicle before.
Finally and the reason for my post is I am not trying to sell them, only a few left, but is anyone aware of this device and where they were made. There is a Patent which we have paid for.

Hello Derek, May I ask would this device/gizmo still work on modern day vehicles with all the exhaust monitoring going on nowadays Or just more suited to my 1966 MGB with the only thing with a silicone chip in it is the radio Ian.
I too shared your reservations especially with the advent of OBD and O2 sensor.
I fitted a CEV to my 98 Honda having first videoed not only the emissions but the Lambda switch, which was rather lethargic. In attendance was Dr Terry O'Neill PhD MBA MSc Chartered Engineer(MIEE) and Chartered Physicist(MIoP).
Having connected the device, started the engine and ran on fast idle for a short whilst monitoring the Lambda. Entering closed loop the the count was much faster as if we had fitted a new sensor. Quickly we hooked up my Lucas 5gas inc NOX Analyser (I'm sure Darren Bamford could vouch for this splendid machine) and were surprised how quickly the emissions dropped. The drop in oxygen levels and rise in carbon dioxide together with steadily reducing CO & HC figures showed how more efficient the engine had become.
The engine was noticeable smoother tacho being rock solid at idle.
We have since fitted a CEV on my Son's Skoda Superb,the works Berlingo diesel and Terry's (although recently passing a MOT smoke test) 1990 Merc engined Motor home and his son's Mondeo 2.0 TDCi. All giving reduced smoke results. Also I have the printout's of former tests showing a drop of 50% to 82.5%.
I'm sure if asked the independent MOT garages who who did the tests,would confirm the device definitely works.
We have yet to fit one to a OBD11 petrol with (pre & after) O2 sensors, which Terry thinks could be a problem.
Update on CEV took Honda Civic Coupe for MOT last week despite 108,000mls 15yrs old and just passing last years MOT with 0.284%CO. Only service parts replaced since.
Went through this time 0.01%CO & 7ppmHC.
I dug out my Kia Sportage last MOT with just 4,428 on clock they were 0.039%CO & 2ppmHC and these cars are renowned for their low Emissions.
