Ethanol-Blended Diesel Fuel Passes Demanding Three-Year Trial

SPRINGFIELD – Ethanol-blended diesel fuel known as “E-Diesel” is comparable in performance to No. 2 diesel fuel when used in heavy duty truck engines. A recently concluded 3-year test and demonstration of the alternative fuel found that E-Diesel performed as well as conventional diesel fuel with no fuel-related or other unusual maintenance problems after nearly 400,000 miles of use in each of two over-the-road diesel trucks.

“This field demonstration was designed to test this experimental fuel under typical driving conditions and to evaluate its potential in the marketplace,” said DCCA Director Pam McDonough. “E-Diesel has the potential to increase the ethanol market by more than 400 million gallons annually.”

For the test, two different E-Diesel blends were used to fuel two 1999 model Mack “Day Cab” trucks equipped with Mack E-7 diesel engines. Number 2 diesel fuel was mixed with 15 percent and 10 percent anhydrous ethanol, and a special blending additive developed by Pure Energy Corporation of New York. The trucks, owned and operated by the Decatur-based Archer Daniels Midland Corporation, made year-round short-to-medium distance hauls.

The same maintenance was performed on both trucks fueled with E-Diesel as with ADM’s regular diesel truck fleet. Oil analyses, taken at each oil change were normal. Engineers will examine key engine parts for wear, including the fuel pump, fuel lines and fuel injectors, all original factory installed equipment.

“E-Diesel is coming,”said ADM Senior Vice President Marty Andreas. “This real world demonstration confirms that E-Diesel is a fuel with a future.”

Test results from this project have identified fuel economy and cost as the only appreciable differences between E-Diesel and regular diesel fuel.

For mileage comparison, 10 percent and seven percent reductions in fuel economy corresponded with 15 percent and 10 percent blends of ethanol and No. 2 diesel fuel respectively. E-Diesel also was found to be slightly more expensive than No. 2 diesel fuel, due to the limited production of the special blending additive. E-Diesel, when commercially available, is expected to cost a few cents more per gallon than conventional diesel fuel.

The ADM truck test was sponsored by the Illinois Department of Commerce and Community Affairs (DCCA), in cooperation with Mack Trucks, Growmark, Corn Belt FS, Williams Energy, Pure Energy Corporation of New York, Archer Daniels Midland Corporation, and the Illinois Corn Growers Association.

In other tests, E-Diesel significantly reduced particulate emissions in diesel engine exhaust. E-Diesel was found to reduce particulates by 20 percent or more, even in the newer diesel engines designed to meet today’s stringent air emission standards.

DCCA manages ethanol test and demonstration projects designed to encourage economic growth in both industrial manufacturing and agriculture. Illinois is the nation’s leading producer of ethanol.
