Simple new fuel-injection technology applies electric field to increase car mileage and reduce emissions

September 30, 2008

Researchers at Temple University in Pennsylvania installed an electrically-charged tube around a car’s fuel line near the fuel injector and resulting in an increase in mileage from 33 mpg to 37 mpg. Based on  a principle called electrorheology, the field reduces the fuel’s viscosity, effectively atomizing the fuel droplets, increasing the mileage while decreasing emissions.  From the study’s abstract:

“Because combustion starts at the droplet surface, smaller droplets lead to cleaner and more efficient combustion. Both laboratory tests and road tests confirm our theory and indicate that such a device improves fuel mileage significantly. The technology is expected to have broad applications, applicable to current internal combustion engines and future engines as well.”

The study will be published in the November 19th issue of ACS’s publication, Energy and Fuels.

The  technique is relatively simple to implement in future car designs, or even as a retrofit.

Lower pollutants, a 20% increase in fuel efficiency – when can we buy this?

Interesting, I will look forward to more info. BTW - magnetic fields and electric fields aren't the same things. This isn't cow magnets. It might not work any better but it's still not the same thing. Also, typical Fuel injection pressure is about 40 to 60 psi depending on the vehicle. That 9 to 15, that was back in the day of carburetors. Oh yea, and fuel does have droplet properties in the engine (even after compression) ... it's one of the main advantages that fuel injection has over carburetion (hence the higher pressure to 'atomize' the fuel through the small openings in the injectors). Nice articles today Margery.

Wouldn't heating the fuel also reduce the viscosity? Headhunter, how do you define fuel burn efficiency? That one, I'm not familiar with. Are you referring to the Carnot cycle? Or are you saying that we only burn 40% of the fuel that goes into the engine? (Not likely given the nearly stoichiometric operation of modern engines.)

Headhunter commented:

An auto mechanic most of my life, gas turbine specialist, and efficiency freak, I believe this may have some merit. Although it isn't any kind of cure all. Fuel atomization is critical for a complete burn. Fuel droplets will tend to accumulate or condense the longer they take to arrive to the combustion cycle, thus fuel injection pressures have dramatically increased (60psi and up). Inducing a static charge will help to stratify the fuel spray and concevably improve combustion and the resultant yield of each gram of fuel. Considering fuel burn efficiency is currently about 40%, there is a lot of room for improvement.

It is correct that the goal is to ignite a mixture of fuel vapor and air, not atomized fuel and air. The concept is valid.

I did something like that almost 15 years back, lifted my fuel rail to 300v - funny times back then.. ! Didnt think petrol had the property suggested in the article but it can hold a charge if its an insulator, sort of gets upset if you add alcohol as that conducts electricity fairly well.

I was told about this 3 yrs ago. Eetman theory also comes into play where electromagetism imparts not only extra speed on the electrons, but also extra energy. Eventually someone will produce your ideas, if you don't do it yourself.

I don't understand how the fuel spent 5 seconds in the electric field without having a second fuel tank to act as a reservoir. The pictures show a device far too small to hold that much fuel. Also, the experimental data listed some 100psi fuel pressure. I don't know what typical diesel fuel pressures are but the link from: autorepair.about.com/cs/faqs/l/bl015h.htm says it should be 5 to 19psi?

Sounds like the old technology of using cow magnets around the fuel line to increase mileage. The ads were in the back of Popular science in the last century.

I had to look at my calendar first to make sure this was not April 1st. Having said this, if this is for real, I hope that a patent has been applied for and that the results are independently validated. This will pose a great chance for snake oil representatives to sell cheap (non functional) knock offs. I will reserve other comments until I get a chance to read the entire study. An electric field (what voltage) in the vicinity of a highly flamable liquid........I am assuming the injector system was modified with a non conductive component to apply the field. This could be interesting, we will see...........
