Cavitation Technologies Announces Results of Water-Diesel Emulsion Initial Testing

Initial testing of Cavitation Technologies, Inc. (CTI) new HydroFuel water-diesel blend indicates that using 10-20% water-in-oil emulsion (diesel) allows the reduction of fuel consumption by up to 12% and reduces the emission of NOx by 40%, and that of sulfur dioxide and hydrogen sulfide by 50%.

A recent trial at the CTI testing facility showed 17,269 BTU/lb with 10% water in #2 Diesel and 16,698 BTU/lb using a 15% water blend. By comparison, soybean B100 biodiesel has heat energy of 17,035 BTU/lb, while straight #2 diesel has heat energy of 19,494 BTU/lb.

CTI’s technology, which mixes and processes fuel with cavitation and preparation of fine water-in-oil emulsions, can be used not only in marine diesel engines, but also in boilers and turbine power generators. The apparent result is a more efficient burn and is a cleaner emission as well as lowered operating costs, particularly for marine diesels and turbine power generators.



This has been well known for many years. Even gasoline ICE cars operate better (more power + less fuel consumption) on wet rainy days.

How does it effect engine's wear?

Water being very cheap, it seems that a 10% mixture could do a lot for reduced fuel consumption, reduced operation cost and reduced pollution.


Yes Total developed AQUASOL 10 years ago, an emulsion with 5% water. The problem is that the emulsion has a limited stability over time, like one year.

I think a bio diesel with 10% water should be a dramatic improvement in term of emission.

I think they is problems below freezing. I remember the Argus aircraft use to use 50/50 water and alcohol mix. It was a separate tank.


Interesting they do not discuss the cavitation effect on increased heat output of liquids - even nonvolatile liquids.



If the emulsion was done at the gas station, would that solve the problem?

My understanding from looking at their website is that the emulsion is created on the fly just prior to use of the fuel. At least, that's how they do it on ships. Seems you ought to be able to scale this approach down to semi-truck applications, and that's also implied by their website.
