Background Flexi Fuel Vehicles # E10

In some American countries for a long time even offered E85 - and bought. Recently, moreover, in Sweden. Cars for these markets are especially prepared: Everything that comes into contact with the fuel must be from the alcohol can. The tank must be higher, because ethanol has less energy content. The fuel pump needs more fuel and is therefore designed to promote greater.

It gets even added a requirement: As it can in these countries is no nationwide offer E85, and the deals vary in time, the car must also make do with lower ethanol or methanol content and even use pure gasoline. The fuel pump must therefore depend the alcohol content, promote more or less.

The amount of fuel and ignition timing must be adjusted depending on the alcohol content. To make this all could be controlled, had an appropriate alcohol sensor to be invented. This consists of an electrical capacitor, its capacitance changes depending on alcohol content. He is a co-invention of Siemens, Daimler and Volkswagen. Meanwhile, the alcohol content can also be determined from the exhaust gas, the oxygen sensor can make today.

The ethanol ratio always remains below 100% because a pure alcohol Difficult starting. So when you mix a minimum of fuel, so that the car starts cold.

Furthermore, as the weekend has been the head of BMW mechanics developer announced, the engine oil to the alcohol content of the fuel to be adjusted. And at the end of the chain and the catalyst.

This flexible or multi-fuel capability is perhaps eventually called up? For the car manufacturer a conversion to ethanol or methanol is much cheaper than the development of hybrid and electric drives. However, as already reported this morning, the CO2 balance of the ethanol used very specifically. As long as we grow extra food for gewpnnen is hardly anything. What

but from above it may already suspect, the compatibility of alcohol in the car has developed a purely be. The compatibility must apply long term. It should not come to life shortening of the motor or increased wear.

the way Brazil has experienced some turbulence with the acceptance and the availability of its original E85. First, there were strong incentives. Then, the demand grew so strong, because people switch to ethanol engines, ethanol that Brazil had to buy abroad. The price rose and demand fell again. You can tell you is what a high standard of our supply of gasoline and diesel strictly defined places. Our engines are highly optimized in this country to these specifications.

What bugs me on the issue is that I have every two years, an attack of ward policy needs to take to drive my car may continue. And this despite all the laws and regulations to bring anything: My car does not emit particulate matter increased (because there is no diesel), but I had endless running around the green because of the badge. Then came E5 and I had to search again. Now comes E10, which brings the price structure in motion again, with upward trend.

is the requirement of the EU to reduce CO2 emissions from cars by 10%. The original idea for it to blend ethanol into gasoline, comes from a certain amount of usable ethanol, was obtained in the existing agricultural "eh". And since you have so anticipated: renewable raw materials, we call that grow as fast as we consume them. Then you have that is a balance between production and consumption of CO2. For it is that a plant when it is burned emits as much CO2 as it has removed the growth from the atmosphere. The 10% ethanol in gasoline car that is not counted as CO2 emissions. Nothing so simple as the ethanol content in gasoline to increase just always on?

No, because that applies only to "Eh-da" plants. As soon as you start to build a targeted and so extensively to fertilize, or plant even at the other end of the world to grow and then transport them to Europe, from the degenerates quickly into nonsense. practiced on a large scale, all produced a CO2 surplus and it takes literally by his consumption of agricultural land to other peoples, not only the margarine on bread, but the bread with the same.

Today's large-scale produce "biofuel ethanol to give long term, is almost as if you pump up into as large scale water on one side of a mountain to the waterfall on the other mountain side, a hydroelectric plant to power and the whole self-soothing "renewable" call.

ethanol fuels are therefore only there and only on site-a strategy that works for the reduction of CO2 emissions, and, incidentally, to reduce their own dependence on oil, where there is "eh" excess acreage for renewable resources. In Brazil, for example, no one builds electric cars, but "Multifuel" engines. They are designed so robust that one purely because everything can overturn what drives when burning a piston in a cylinder. Of course, one could block such engines in Europe. Our engines are now also ready for LPG, and E10. But for the reasons mentioned above should be the latest on E "10" end. Rather, at E5.

So it is not strategically to increase the ethanol content in gasoline to reduce its carbon emissions.

we come to another resource which is "anyway" was published offal as a meat meal. This must in the EU so can not be used as animal feed to prevent diseases such as mad cow disease and Kreutzfeld-Jacob, which are triggered by degenerated proteins. I've simplified the states are as follows: Animals should not eat animals, otherwise they are weak-minded. (Similar to the gene pool.) But that's not so common. Animals are only vulnerable to light degenerated proteins from their own kind to me as an engineer immediately, because computers are only vulnerable to viruses that have been developed for their operating system. Other viruses simply do not work.

Then we could go then, and allow meat and bone meal as animal feed again, just not the same kind that sent the meal. Mixing should be prohibited.

That would be worth it for our CO2 footprint. For the offal "anyway". If you build vegetable animal feed to extra costs which in turn area, fertilizer, and above all, money. All over the world uses one slaughterhouse waste as animal feed, therefore, not only in the EU.

What we are much more likely than meat consumers need a labeling of meat and sausage with information on the following production stages (ethical factors in here taken equal to): 1 Was acceptable food uses? 2. We were kept animals? 3. How was it slaughtered?
