Development of biodiesel for use in high-speed diesel engines
- Univ. of Idaho, Moscow, ID (United States); and others
Personnel from the University of Idaho have pioneered the use of transesterified rapeseed oil as a diesel fuel substitute. Since 1979, they have been involved in development of recipes for biodiesel, engine testing and evaluation, long term fuel storage, materials compatibility and tests with off-road and on-road vehicles. A method for producing methyl esters of rapeseed oil (RME) has been developed and used to prepare several thousand gallons of biodiesel each year. More recently, a recipe has been developed for preparing ethyl esters of rapeseed oil (REE). In the last year 1600 gallons of REE have been produced and used in the fuel characterization and engine testing program. Recent data has included biodegradability, acute aquatic toxicity measurements, operating an on-road vehicle for over 16,000 miles on REE including trips to both the Pacific and Atlantic Oceans and back. This is believed to be the first coast-to-coast trip on 100 percent biodiesel. Emissions tests at the Los Angeles Metropolitan Transportation Authority Emissions Test Facility showed a reduction in HC (54.6%), CO (48.8%), and NOx (11.6%) and an increase in CO{sub 2} (1.1%) and PM (8.0%). The results for PM are not significantly different from diesel. The other results were significantly different (P<.05).
