With the high cost of gasoline and diesel fuel impacting costs for automobiles, trucks, buses and the overall economy, a Temple University physics professor has developed a simple device which could dramatically improve fuel efficiency as much as 20 percent.
According to Rongjia Tao, Chair of Temple’s Physics Department, the small device consists of an electrically charged tube that can be attached to the fuel line of a car’s engine near the fuel injector. With the use of a power supply from the vehicle’s battery, the device creates an electric field that thins fuel, or reduces its viscosity, so that smaller droplets are injected into the engine. That leads to more efficient and cleaner combustion than a standard fuel injector, he says.
Six months of road testing in a diesel-powered Mercedes-Benz automobile showed that the device increased highway fuel from 32 miles per gallon to 38 mpg, a 20 percent boost, and a 12-15 percent gain in city driving.
The results of the laboratory and road tests verifying that this simple device can boost gas mileage.
“We expect the device will have wide applications on all types of internal combustion engines, present ones and future ones,” Tao wrote in the study published in Energy & Fuels.
Further improvements in the device could lead to even better mileage, he suggests, and cited engines powered by gasoline, biodiesel, and kerosene as having potential use of the device.
