The Agricultural Engineering Department at the University of Missouri-Columbia has fueled a 1991 and a 1992 Dodge pickup Cummins engine with 100 percent methyl-ester soybean oil (biodiesel) for more than 172,545 km (107,215 mile). The 1991 pickup has been driven 89,888 km (55,854 mile) and the 1992 pickup has been driven approximately 82,658 (51,361 mile). Fueling the 5.9 L (360 in{sup 3}) engines with 100% biodiesel initially increased engine power by 3% (1991 engine) and reduced power by 7% (1992 engine). However, both pickups produced less power while fueled on biodiesel during the last series of chassis dynamometer testing. The pickups averaged 6.9 km/L (16.6 mil/gal). Analysis of engine lubrication oil showed that the engines were wearing at a normal rate. Black exhaust smoke normally observed when a diesel engine accelerates was reduced when the diesel engine was fueled with 100% biodiesel. Increased EPA exhaust emissions requirements for diesel engines have created much interest in the use of biodiesel as a fuel for diesel engines.
