BE85 fuels could be environmentally friendly alternative energy instead of fossil fuel pollution levels from the combustion process is quite high.
BE85 as bioethanol fuel can be used for motor gasoline with a mixture of 85 percent bioetanaol and gasoline (premium) 15 percent. It is compared with premium fuel, BE85 has advantages in terms of thermal efficiency or heat generated from combustion.
Produced the largest thermal efficiency BE85 on motor gasoline is 17.44 per cent at engine speed 3000 rpm (round per minutes). While the premium occurred at 7500 rpm at 20.36 percent.
"This is related to the temperature of exhaust gas generated from each fuel,"
the temperature of exhaust gases from burning fuel BE85 is lower than the premium. This is due to the heating value or heat BE85 lower than the premium so that the heat energy released is also low.
In the largest engine speed, exhaust gas temperature standard BE85 is between 530 to 540 degrees celsius. While the premium reaches 870 to 890 degrees Centigrade in the largest engine speed.
However, owned energy content of ethanol is smaller than the premium. Therefore, to obtain power equal to or greater than the premium, one of which is to supply more fuel.
"This can be done by way of enlarging the diameter of the machine,"
If it goes perfect, the process of burning fossil fuels produces carbon dioxide gas only. But, in fact, complete combustion does not take place so that the process also produced carbon monoxide, hydro carbon and nitrogen gases endangering human health.
As for bioethanol in general have more oxygen content so that it is more complete combustion process and it can reduce the formation of carbon exhaust. Other types of alcohol fuels tested in various countries is methanol. (Ant / Bey)
