I was reading the DM online this week and an article caught my eye. About an ex Royal Navy engineer who, from his experience with submarine oxygen generation, has developed working and tested units that will improve the engine burn and cut emissions, which result in fuel savings for vehicles from cars, small and large vans right up to HGV and coaches. I have no personal knowledge of these units but had a good look at their website and the information there looks sound? Having run a fleet of cars, vans and trucks for my refrigeration company in years past, I thought others might want to investigate for themselves. The site is cgon dot co dot uk I would be interested to hear peoples views?
