Prevent Water Contaminated Fuel Damaging The Engine

Submitted 8 years ago

I have been working in the clean fuel solutions business for the past 12 years and everyone agrees water is the No 1 contributor to fuel contamination.

Current practice in combating this problem is fuel filtration � may it be particulate, water coalescing or water absorbing filters.

I read a paper that puts the fuel filtration market at USD6-8 billion/yr. But this is still treating the symptoms and not the cause.

And to add insult to injury � engines are still getting damaged even though fuel filtration is in place.

All so often we hear

� Driver filing up
� vehicle breaking down soon afterwards
� Driver has no idea WHY
� Mechanic finds dirty fuel
� Fuel supplier standard reply � isolated incident
� So � who is responsible for the repair bill?

With no real solutions in the horizon I decided to develop my own.

Our approach is very different, instead of relying on fuel filtration to prevent engine damage, why don�t we prevent the engine from starting or putting the engine into limp mode, as soon as water is detected inside the engine fuel tank?

One can argue, OEM can simply reposition their WIF sensor into the fuel tank and reprogram the EMU to do the same.

A few critical problems we managed to resolve:-

� A typical WIF sensor operating on 12-35V and some Amps will suffer badly from electrolysis (See pic of Parker sensors � left 2 is under normal application far right sensor going through our controller)

� Our ability to read all ages of water � bacteria laden water is a quiet different to clean tap water

Being a Land Rover owner myself - this kind of technology goes very well with the brand.
