EMA issues technical statement on biodiesel

12 March 2003

The Chicago, IL-based Engine Manufacturers Association (EMA) published a technical position statement on the use of biodiesel fuel in diesel engines. The statement provides an assessment of the potential effects of the biodiesel fuels use with current technology engines.

In the statement—while admitting that the information on biodiesel effects on engines that were not designed for that fuel is still limited—the EMA concluded:

The conclusion that biodiesel bends greater than B5 should not cause problems when used in existing diesel engines is consistent with the Common Position Statement issued in June 2000 by a consortium of fuel injection equipment (FIE) manufacturers. The FIE Manufacturers concluded that fuel injection systems can be designed for operation with neat biodiesel fuel (B100). However, in equipment designed for petroleum fuels, blends greater than B5 can cause reduced product service life and injection equipment failures.
