Bio-fuel for cars

The present veh?culos & lt; p& gt; they face a challenge to happen of exhausting and polluting of renewable fuels highly f? ? siles to and the combustible ones like m?green s See-fuels that are less polluting and can be mixed with fuels f? ? siles or to be used separately. We are going to discuss on some of these see-fuels. & lt; /P& gt; 1. Ethanol: caña is known them comúnmente like grain alcohol produced from vegetal sources like ma?z or azúcar by fermentaci? ? n. The ethanol has a high número of octane that produces a high efficiency of the motors. At world-wide level the ethanol est?gaining vile popularity and many manufacturers of autom? ? est?n developing veh?culos Flexi-Fuel (FFV). The veh?culos Flexi-fuel that use a mixture of gasoline and ethanol in one proporci? ? n of ethanol are as high as 85% with the gasoline a 15%. These fresh fruits and vegetables have one opci? ? n of percentage vari? ? of ethanol and gasoline. Now compañ?as est?n investing in doing this like m?s efficient and less polluting fuels. Bioetanol is the carbon-neutral one and has one of the very low emissions of di? ? xido of carbon during the use of the fuel and también during producci? ? n. & lt; /P& gt; 2. GLP Car-gas: This f? is a sil fuel ? that are very low polluting agents like of di? ? xido of carbon and xidos ? ? of nitr? ? geno in comparaci? ? n with the gasoline and the diesel engine. Light modificaci? ? n in the ready motor of combusti? internal ? n har?a to use GLP like fuel. GLP has a special property to turn to l?quido to presi? atmosférica ? n and can properly be stored in l?quida form. & lt; /P& gt; 3. Compressed Natural gas: Like the GLP, the GNC f? is a sil fuel ? and has a very low level of di? ? xido of carbon of emissions in comparaci? ? n with the gasoline or the diesel engine. Like the GLP, the veh?culos must be put under one conversi? ? n before being ready to use GNC like fuel. The GNC cannot be stored in l?quida form and it is stored in the form of gas compressed in cylinders like the GLP. GNC has stop value of the octane, therefore it is the efficient fuel. & lt; /P& gt; 4. Biodiesel: Produced from vegetal sources like oilseed rape, the sunflower and the oil of soybean. Biodiesel is green and is neutral in carbon since xido of carbon has done it of the very low emissions of di? ? during the use and producci? ? n. biodiesel can replace gas? ? I read in many cases, but the manufacturers of veh?culos are cautious and recommend 5% to 30% of biodiesel mixed with gas? ? I read in principle to study the wearing down. The modern motors are able to use the 100% of see-fuel. & lt; /P& gt; 5. Fuel cells: Aún in phases of investigaci? ? n can be soluci? ? n of vanguard. Fuel batteries are electro-qu?micas devices of conversi? electroqu?micos ? n of energ?a that turn energ?a of reacci? ? n. The electricity can continuously be produced, as long as the reagents are provided. At the moment this tecnolog?a is very expensive and todav?a est?in investigaci? ? n. & lt; /P& gt; Another caracter?stica of the see-fuel in debate is the fact that aumentar?presi? ? n on producci? ? n of grain foods as some of these see-fuels are of vegetal origin. producci? ? n in mass or podr?a to give rise to one reducci? ? n of the surface available for producci? ? n of grains for alimentaci? ? n or habr?one deforestaci? massive ? n. Although ? exists an urgent necessity to pass of fuels f? siles to fuels m?s green también is a clear necessity to quantify the impact in producci? ? n of grain foods and deforestaci? ? n. & lt; /P& gt;
