The technical definition of biodiesel is as follows: Biodiesel, n - a fuel comprised of mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats, designated B100, and meeting the requirements of ASTM D 6751. PPpI7S-ggI\F,[f6R0w20l! This can be defined as biodiesel fuel properties in terms of physical and chemical properties such as viscosity, density, bulk modulus of compressibility, sound velocity, cetane number, iodine value, surface tension, thermal conductivity, chain length, heat capacity and fuel composition. %PDF-1.5

Full Length Article Physical and chemical properties of RME biodiesel exhaust particles without engine modications Robin Nystrma, Ioannis Sadiktsisb, Trifa M. Ahmedb, Roger Westerholmb, Johannes H. Koeglerc, Anders Blombergd, Thomas Sandstrmd, Christoffer Bomana, a Thermochemical Energy Conversion Laboratory, Department of Applied Physics and Electronics, Ume University, SE-901 87 . Biodiesel is a renewable, biodegradable fuel manufactured domestically from vegetable oils, animal fats, or recycled restaurant grease. When a diesel engine is operated with biodiesel, exhaust emissions decrease; approximately 20% in CO, 30% in HC, 40% in particulate matter (PM), and 50% in soot emission, compared to the diesel fuel. Results indicated that additives can improve cold weather properties but canola oil, soybean oil, palm oil, and lard based biodiesel with 2 weight-percent of Wintron XC30 and XC40 additives could not achieve the viscosity requirement therefore those additives were not applicable with that concentration. The solvency properties of the biodiesel can cause microbial slime to detach and clog fuel filters. A general understanding of the various properties of bio-diesel is essential to study their implications in engine use, storage, handling and safety. High unsaturated acid content can lead to lower pour points but less stability for storing. The vegetable- and animal-derived feedstocks used to produce biodiesel are known as triacylglycerides (TAGs), or more simply, triglycerides. It will also require replacing rubber seals in older engines. Sort by Weight Alphabetically Agriculture & Biology.

For example, methyl esters produce more torque per unit of biodiesel used compared to ethyl esters. Adding biodiesel as a blend with ultra-low sulfur should improve lubricity for ultra-low sulfur diesel fuel, which will improve engine wear.
