Welcome to the site.

I'd really only believe this if I saw some dyno testing proving this. Driving alone can account for way more than a 20% increase in FE as we here know. While smaller droplet size will vaporize gasoline faster, current engines exhaust so little unburnt fuel I doubt there is 20% FE to gain. Interesting first post though.

i figured since it was in a few science magazines it was more credible . i think i found in gizmag with a link to science daily . it looked so simple someone handy could put one together and test it .

Welcome to EM! I googled "temple university fuel saving device" and found these URLs :

Reality Check - A New Fuel Saving Device | New Energy and Fuel
Quote:
They further explain, “The fuel flows through two metallic meshes before it reaches the fuel injector. A voltage is applied on the two meshes to produce an electric field of around 1.0 kV/mm between the two meshes. The device consumes very low electric power, less than 0.1 W. In our setup, the rheologic field direction is opposite the flow direction, which may help to provide negative charges to the fuel droplets. However, the main function of our device is to reduce the viscosity of the fuel as it passes the electric field.” The key is to get the fuel negatively charged, as fuel particle sizes will be small if their charge density is high, and no fuel agglomeration can occur because the negatively charged droplets repel each other. This key of chemistry is the point that kills the skepticism. Gee, if I weren’t so impressed by the innovation of putting the field in the fuel so making it a rheological procedure, rather than around it as with so many electromagnetic devices from the past or ideas about electrostatic atomization that may or may not prove practical, it would be just another dreamy idea.

Electrorheology Leads to Efficient Combustion

I don't know if it's for real, but at least it claims to use almost no juice.

I call shenanigans...

The device is from a company (Save the World Air, INC) that sells fuel magnets with a claim "enhance fuel efficiency up to 33%"..... As such, my respect and general feeling of credibileness is low.

Why is it that I can't find any contact information for the houses that did the testing? And why so many testing firms out of the US - where the device was developed....

The fuel that goes into your motor is almost completely burned. We're talking ~2% is leftover. the combustion itself isn't the problem.

I was wondering when this would show up here...

The quality of the "data" on which they're making claims is laughably poor. Any PhD publishing "results" from on-road use of a 20ish year-old, technologically outdated car which isn't even close to being representative of an average vehicle as the test bed ought to be sent back to school, never mind researching & teaching.

Next, follow the money: SEC Info - Save the World Air Inc - 8-K - For 2/2/07

The good professor and/or the university is being paid serious coin from the company trebuchet mentions to produce "research" for them.

Waaaay too many red flags to take this seriously.

A believable summation in the comments below the psychopath analysis:

Quote:
This seems entirely plausible to me for a couple of reasons. Firstly, you definitely *can* get better power and fuel economy by better atomisation of fuel in a diesel engine, which is why high-pressure, common rail diesels are so much better. Secondly, this is an ancient engine, designed well before the kind of modern techniques that mean current engines only fail to burn a small percentage of fuel. So combine a novel, but crude, technique to better mix fuel and air with immature diesel engine design and you see a nifty improvement.

So whilst it seems plausible, it’s also pretty trivial.

Apply this technology to a modern common-rail diesel engine and i bet you see zero improvement (as you expected).
Or a modern, fuel-injected gasoline engine for that matter.

I have a Simple Device Which Uses Electrical Field Will Boost Gas Efficiency Up To 20% Or More... it is a tachometer controlled microswitch, set to activate at 2000 rpm. It energizes a circuit which consists of a cattle prod transformer with the outputs connected via jumper cables to your privates. Another incorporated function for circuit activation is a WOT switch. Cheap, effective. Wanna test it? :P
