CGON hydrogen additive


Barry

Recommended Posts

I stumbled across a company in the U.K. called cgon who sell a device that adds hydrogen to the fuel-air mix which claims to  increase fuel efficiency by up to 25%. They also claim that it reduces emissions by up to 80%. One customer testimony on the website claims their gas mileage was increased by 33%. 

So,

Real or snake oil? I call snake oil because it's been around for 2 years and the manufacturers haven't adopted the technology then it can't be up to much

Snake oil- even without reading the article you reference.

Even with the addition of some hydrogen to the air/fuel mix there is no way to reduce the emissions caused by the hydrocarbons in the petroleum fuel component of the mix by 80%. Moreover, without a re-flash of the ECU to re-calibrate oxygen sensors/fuel/air ratio sensors, exhaust gas temp sensors, and Nox sensors (among others) the ECU will just enrich the fuel mixture when it reads a fuel mixture that is 80% leaner than it should be. So, no 33% increase in gas mileage, either.
