Biodieselfuelled

Biodieselfuelled is a term used to describe engines, vehicles, or systems powered by biodiesel or biodiesel blends derived from biological oils or fats. Biodiesel is produced by a chemical process called transesterification, which converts fats or oils into fatty acid methyl esters (FAME) and glycerol. Common feedstocks include vegetable oils such as soybean, rapeseed, and palm, as well as animal fats and recycled cooking oil.

Most modern diesel engines can operate on biodiesel blends from about B2 to B20 without significant modification. Higher blends and pure biodiesel (B100) may require attention to fuel-system materials, seals, and cold-weather performance. Biodiesel generally increases lubricity and can improve cetane number, but it can also have solvent effects on older elastomeric components and may interact with certain fuel additives. Proper filtration and storage practices help maintain stability and prevent water-related issues.

Environmental and sustainability considerations are central to biodiesel use. Lifecycle greenhouse gas emissions are typically lower than those of petroleum diesel, particularly when high-quality feedstocks are used and land-use impacts are managed. Biodiesel is biodegradable and produces lower sulfur emissions, though feedstock supply and agricultural practices influence overall environmental outcomes.

Regulation and standards provide the framework for production and use. In the United States, standards such as ASTM D6751 apply, while in the European Union EN 14214 is used. Biodiesel blends are common in transportation fleets, municipal vehicles, and some industrial applications, contributing to renewable fuel targets and emissions reductions in many regions.
