Electricity gets more out of
Send gasoline or diesel fuel through
a strong electric field just before it goes into a fuel injector and
you can boost a vehicle's fuel efficiency by about 20 percent.
Electric fields reduce the viscosity of fuels, which means
that when the fuel is sprayed from a fuel injector the droplets are
much smaller. Smaller droplets burn more thoroughly, which increases
fuel efficiency and results in cleaner combustion.
Lab tests showed that the process increases fuel mileage by
just over 20 percent. A six-month road test with a Mercedes-Benz improved
highway mileage from 32 miles per gallon to 38 miles per gallon, an
18.75 percent efficiency gain. The gain for city driving was 12 to
The device's small size and simple design mean that existing
cars could be retrofitted to use it.
