Flexifuel vehicle for ethanol and petrol
The flexifuel car has a combustion engine with a flexible injection system. Any blend of fuel from E85 (85% ethanol and 15% petrol) to 100 % petrol can be used in this car. The car is provided with a sensor that measures the conductivity in the fuel, and thus determines the ratio of the blend. The signals are later sent to a powerful computer that controls injection, ignition time and quantity of air. Injection is increased and substituted with resistant material for large quantities to be injected. The vehicle is basically a standard car. The obvious differences are that engines with only E85 are about 7% more powerful than pure petrol engines, and the fuel consumption increases by 30%, as the energy content pr litre of ethanol is lower. However, the energy is utilised much more effectively. Using ethanol is just as expensive as petrol, despite the fact that the consumption of ethanol is higher. This is because ethanol fuel is cheaper because of low tax.
