BIOFUEL

The biofuel is a future of the automotive industry as it will substitute contemporary gasoline or petrol. The main foal of synthetic biology approach is to modify the genetic pathways that bacteria, plants, and animals use to make fatty acids, one of the main ways that organisms store energy. Fatty acids are chains of carbon and hydrogen atoms strung together in a particular arrangement, with a carboxylic acid group made of carbon, hydrogen, and oxygen attached at one end. Take away the acid, and you're left with a hydrocarbon that can be made into fuel. As the result scientists will get the crude oil without the contaminating sulfur that much petroleum out of the ground contains. The crude, in turn, would go to a standard refinery to be processed into automotive fuel, jet fuel, diesel fuel, or any other petroleum product that someone wanted to make.

Bio diesel is produced from renewable energy sources such as rapeseed, sunflower or soybean oil. It can be made from virgin oil or waste oil from restaurant fryers. It is refined through a process known as transesterification in which glycerin is removed making the oil less viscous (thinner liquid) and more stable. Biodiesel is non-toxic,biodegradable, has a proven track record of millions of miles worldwide and is available now. Biodiesel is green as it has the potential to be carbon-neutral, that is to say all the carbon dioxide emitted during use of the fuel when emitted from the vehicle is balanced by the absorption from the atmosphere during the fuel crop's growth.

Biodiesel in some instances can be a direct replacement for diesel, however most manufacturers remain cautious about engine wear and recommend a blend of between 5% to 30% biodiesel although some modern engines are capable of running on 100% biodiesel. Biodiesel greatly lowers tailpipe emissions that contribute by vehicles to global warming, acid rain and many respiratory health problems. Biodiesel makes car engines run smoother and last longer. Biodiesel will work in any diesel motor with little or no modification. Biodiesel is actually better for car engine than petroleum diesel. As little as 1% biodiesel added to petro-diesel provides 65% greater lubricity. Biodiesel testing shows less engine wear, which extends engine life without losing the power.
