Canola Methyl Ester Operation in Northern Climates.

Operating diesel engines in northern climates can be a challenge; operating diesel engines using bio-fuels such as Canola methyl ester can be even more of a challenge. Temperatures in North Dakota can range from 35 degrees Fahrenheit to -30 degrees Fahrenheit during the winter months. Canola methyl ester, when exposed to these temperature extremes can be fluid or can have the consistency of margarine. Operating equipment using bio-fuel is possible, but only with planning and preparation. Prior to the cold arctic months of a North Dakota winter, bio-fuel must be preconditioned. Additives, anti-gelling agents, tank mixes with #1 diesel and controlled temperature storage can make winter use of Canola methyl ester possible. Some manufacturers equip their fuel systems with heaters and fuel recirculation systems. Bio-fuel storage is also a major concern in extremely cold temperatures. The North Central Research Extension Center in Minot, North Dakota has been conducting a research demonstration project since April 2005 to test the limitations of bio-fuel use in northern climates.
