biodiesel,

fuel made from natural, renewable sources, such as new and used vegetable oils and animal fats, for use in a diesel enginediesel engine,
type of internal-combustion engine invented by the German engineer Rudolf Diesel and patented by him in 1892. Although his engine was designed to use coal dust as fuel, the diesel engine now burns fuel oil.

. Biodiesel has physical properties very similar to petroleum-derived diesel fuel, but its emission properties are superior. Using biodiesel in a conventional diesel engine substantially reduces emissions of unburned hydrocarbons, carbon monoxide, sulfates, polycyclic aromatic hydrocarbons, nitrated polycyclic aromtic hydrocarbons, and particulate matter. Diesel blends containing up to 20% biodiesel can be used in nearly all diesel-powered equipment, and higher-level blends and pure biodiesel can be used in many engines with little or no modification. Lower-level blends are compatible with most storage and distribution equipment, but special handling is required for higher-level blends.

Biodiesel is made from oils or fats, which are hydrocarbons. Fresh soybean oil is most commonly used, although biodiesel can be made from mustard seed oil or waste vegetable oil (such as used oil from restaurant deep fryers). These hydrocarbons are filtered and mixed with an alcohol, such as methanol, and a catalyst (sodium hydroxide or potassium hydroxide), resulting in a chemical reaction whose major products are the biodiesel fuel and glycerolglycerol,

Neither were associations noted for HDL-C or apolipoprotein A-1 among women with low apolipoprotein B100 as the number of participants were small in this category and few events were seen.
Considerando que a concentracao de biodiesel na mistura, atualmente, e de apenas 3% e que isso diminui a sensibilidade do metodo de determinacao do indice de peroxidos, realizou-se o ensaio deste parametro no biodiesel B100 mantido a temperatura de 20[grados]C.
Following problems are apparent in the engine, when it is run on B100 bio-diesel fuel of high viscosity: impact atomization of the fuel being injected into the engine combustion chamber, large drop of fuel caused by high viscosity affect to combustion quality, burn not clean, build up in the engine, around valve, injector tips and on piston sidewall and ring and Fuel does not flow properly through filter and engine injection system.
15%) reported by the 2007 survey of 56 samples of B100 from production plants in the US.

Great River Soy started operations in October 2007 and produced 94,000 gallons of B100 biodiesel that month.
To avoid these problems, most drivers use blends of B100 and petrodiesel mixed at varying ratios.
The addition of B100 tended to reduce shoot and root fresh and dry weights of big bluestem and showy partridge pea (Tables 3 and 4).
There are three basic fuels available to biodiesel drivers: B100 (pure, processed biodiesel from retailers), B20 (a blend of 20 percent biodiesel and 80 percent regular petroleum diesel, also available from retailers), and fryer oil ("recycled" oil from restaurants that is not sold commercially).
Paying higher prices for B100 is akin to spending more for organic milk (which, by the way, will not run in any diesel engine--don't even try it).
According to Enertech Labs, the BioFlow line includes BioFlow 100, BioFlow 1000 and BioFlow 107671A for the treatment of B100 biofuels and bio-lubricants oils, as well as BioFlow 20 for the treatment of blended biodiesel fuels.
