New Technology Blends Ethanol for Cleaner Diesel by Kristin Brekke

Diesel engines may soon have a new partner in the effort to satisfy Tier 4 emissions standards – ethanol.

A Nebraska company has developed a system for bringing a mixture of ethanol and water to a diesel engine just before the point of combustion, increasing the diesel engine’s efficiency and reducing emissions. The business partners behind CleanFlex Power Systems, LLC call the mixture “EM60,” which is 60 percent ethanol and 40 percent water. The overall fuel mix in the diesel engine is 85 percent #2 diesel and 15 percent 120-proof ethanol.

Bob Dickey, a farmer from Laurel, Nebraska, and three business partners are behind CleanFlex. Dickey is past president and current chairman of the National Corn Growers Association, and he and his team were in Sioux Falls, South Dakota last month for a demonstration of the new technology operating in a retrofitted 2005 Ford F250 Powerstroke.

The system requires the use of two separate tanks to deliver the fuel, one for the ethanol-water mixture and one for the diesel. The two come together at the point of combustion and produce a number of benefits, according to Ron Preston, CleanFlex president:

* Reduces NOx by 30 percent or more
* Reduces particulate matter
* Increases horsepower by 25 percent or more
* Increases energy efficiency by 10 to 30 percent

Preston says the EM60 has the ability to help diesel engines meet the U.S. Environmental Protection Agency’s Tier 4 emissions standards that go into effect in 2011. Other benefits of the fuel mixture include added lubricity to the engine, longer storage life for the fuel and the ability to use it in all weather conditions – even down to 100 degrees below zero Fahrenheit.

The hydrated ethanol was first tested last year on Dickey’s farm in a diesel engine running an irrigation system, a John Deere 70-horsepower four-cylinder turbo diesel. He reported increased efficiency and decreased emissions, plus a cost savings of $1 to $1.20 per hour over regular diesel.

The fuel and the retrofit are available today through CleanFlex with an estimated price of $5,000 to $7,500, depending on the vehicle and the engine. They are in talks with ag equipment companies as well as railroad companies on potential use of the fuel and delivery system.

At the Sioux Falls demonstration, Preston estimated that there are 29 million trucks that might not be allowed to operate in California or other places with strict emissions standards under the upcoming Tier IV diesel regulations. The addition of hydrated ethanol to the diesel fuel in this type of retrofit could change that.

Research is being conducted at the University of Nebraska under a two-year grant at the Industrial Agricultural Products Center. CleanFlex can be reached at (402) 480-0346 for questions or product inquiries.

Ethanol Could Make Diesel Engines Greener

A corn grower leader is working on using ethanol to help fuel diesel engines.

National Corn Growers Association chairman Bob Dickey is also chairman of CleanFlex Power Systems, which is so new they haven’t built a website yet, but what they have done is developed a method to efficiently use ethanol in diesel engines.

Dickey started the idea a year ago when he bought a new John Deere 150-hp four-cylinder turbo diesel irrigation system engine and retrofitted it to use an ethanol and diesel blend. “It worked so well that we applied for a grant at the University of Nebraska and we’re currently doing research there to bring credibility to what we’re doing,” Dickey says.

The company has developed a new hydrated-ethanol fuel called EM60 (a mixture of 60% ethanol and 40% water) to combine with diesel fuel to power diesel engines. “Just like oil and water don’t mix, ethanol and diesel don’t mix,” Dickey said. So, they run two lines into the diesel engine. “The only time the ethanol, water and diesel are together is at the point of combustion and it really works well. The engine runs cooler, it runs more efficient and the emissions are reduced.”

CleanFlex president Ron Preston says the fuel they are using is 120 proof ethanol. “Most ethanol plants are putting out 200 proof ethanol and we add distilled water or reverse osmosis water to get it to 120 proof,” he said.

Preston says they are talking with agricultural equipment manufacturers, railroads, and even bus companies about the idea because the EM60 fuel has the potential to help meet Tier 4 emission standards that become effective in 2011. “There are 60 million diesel engines in the United States,” Preston says. “We’ve been working with EPA and going through the proper steps to make ethanol a solution that will help them meet emissions requirements.”

They have already tested the fuel with two and five percent biodiesel blends and it works just as well. “The bottom line is that we can become less dependent on foreign oil,” Dickey says.
