At present, together with France, including many European countries have drawn up ambitious biofuels in the short term plan: in order to encourage the use of biofuels, thereby reducing the use of the proportion of conventional fuels. To achieve this goal the introduction of a new type of fuel we have mentioned several times in fact, that is, E85 fuel, this fuel is 15% of unleaded gasoline plus 85% of the alcohol mixture, and now is gradually in the Europe-wide establishment of the corresponding stations. This fuel has a more competitive price, because for them by the gasoline tax should be much less than conventional fuels. This is the Saab introduced the E85 model then the reasons for, and the Volvo XC90 also introduced a version of the bio-fuels.

However, this new fuel and can not be used for conventional gasoline engine. Because it will react with certain materials, their special physical and chemical substances require the fuel system, direct injection system and other relevant places to carry out any modification in order to work properly. And modified engines can use E85 fuel may also be used in gasoline, the hybrid fuel requirements also reduce the number of gasoline and alcohol can be mixed ratio, even if there is no outside gas stations, they would be home-made fuel.

This technology is currently in Brazil have been relatively sophisticated, Peugeot will be started in September 2007 in Sweden, the Netherlands and France try to launch such a model. External formal name is the BioFlex. In France introduced the first model is the 307 version sports travel and travel version 1.6 BioFlex 110, has a special BioFlex logo to make a distinction between ordinary models.

France began in July from reservations, transportation from the beginning of September. Despite the development of this technology a greater need for more investment in research and development, but the Peugeot 307 has given the first campaign launched in travel and travel version of version 1.6 BioFlex 110 models with the same general pricing, respectively, 20,400 and 19,500 pounds.

Through the use of this new type of fuel the vehicle available to lower CO2 emissions from fuel production to the use of the entire process of both. According to some experts study found that through the use of E85 fuel can reduce CO2 emissions by 30%.
Alcohol production process of CO2 generated by production plants with direct absorption. This is mainly dependent on the plant, production and conversion of the way. Can have in the engine used in E85 fuel than an ordinary gasoline engine to reduce emissions of 5 percent to 307BioFlex as an example, the per kilometer of CO2 emissions to 169 grams, and 178 grams for gasoline models.

Advantages

In France, the public and the drivers to a vehicle as a career through the use of this model first in the vehicle registration can be reduced by 50% of the cost, even in some regions is free of charge. Occupational users can also enjoy the unconventional hire purchase and business, may dispense with TVS (vehicle tax) for 2 years, and have to pay value-added tax can be refunded 80%.

Another advantage is to choose more freely. Because Peugeot has always hoped to expand the scope of use of this technology, so users of this technology is no need to separately pay the R & D: 307BioFlex version of the price of petrol version is the same. And because the tax factors makes the purchase of new cars more fuel value, fuel prices can reduce the level of about 0.8 pounds per liter, compared to the compensation due to alcohol gasoline contains 35 percent less energy and increased fuel usage.

In addition this new engine can use any percentage of the mixed fuel. If consumers want is entirely possible to use only unleaded petrol, and to use such BioFlex with ordinary gasoline cars without any distinction. And finally there is a benefit that the use of E85 fuel higher performance, compared to gasoline models, an increase of 4% maximum torque, maximum power increase of 2.5%.

Proven new technologies

From the 2005 beginning of March, Peugeot began sales in Brazil 206 1.6 liters biofuel models, this model can be used pure gasoline or pure alcohol, or the ratio of two arbitrary mixed. Is to be had on the original engine TU5JP4 some modification, such as direct injection system, spark plugs, valve, butterfly valve throttle valve control unit, piston ring and for the pipeline so as to enable them to use alcohol fuel. Since then, this technology in Brazil began to put into practice, and later launched a 1.4-liter engine is also on the 206, followed by 307 sedan version of the 1.6-liter version of bio-fuels, has so far sold a total of 6 10000.


The 307 brought about by travel and sport version of the travel version of the 1.6 liters BioFlex 110 use the same engine TU5JP4. For the European IV emission standard has been improved. Cylinder volume 1587CC, the maximum power of 80 to 82KW between (5800RPM), because for different oils are different. With the use of 5-speed manual transmission. If you are using mixed fuel, then the performance was stronger than the gasoline engine.

Apart from the engine changes, this European version of the 307BioFlex also digitized the engine control unit to carry out the changes. In fuel supply through the installation of Lambda (EGO) monitors to adjust depending on the fuel supply means. Tank monitoring devices measuring the minimum oil cordon software program changes, will be using a different fuel cordon different positions, because the alcohol the more the faster the fuel consumption.
