Thesis on alcohol consumption

Multifuel vehicles are capable of operating with more than two fuels. Methanol was even more of a challenge than ethanol but much of the early experience gained with neat ethanol vehicle production in Brazil was transferable to methanol. These vehicles could operate on either gasoline or methanol with only one fuel system.

In Brazil, the FFVs are popularly known as "total flex" or simply "flex" cars. Normally, standard gasoline vehicles are retrofitted in specialized shops, which involve installing the gas cylinder in the trunk and the CNG injection system and electronics. The term flexible-fuel vehicles is sometimes used to include other alternative fuel vehicles that can run with compressed natural gas CNGliquefied petroleum gas LPG; also known as autogasor hydrogen.

After extensive research that began in the 90s, a second push took place in Marchwhen the Brazilian subsidiary of Volkswagen launched to the market the first full flexible-fuel car, the Gol 1. After reaching more than 4 million cars and light trucks running on pure ethanol by the late Thesis on alcohol consumption, [63] the use of Eonly vehicles sharply declined after increases in sugar prices produced shortages of ethanol fuel.

Vehicles with this adaptation are known in Brazil as "tri-fuel" cars. Also, liquid fuels were preferred over gaseous fuels not only because they have a better volumetric energy density but also because they were the most compatible fuels with existing distribution systems and engines, thus avoiding a big departure from the existing technologies and taking advantage of the vehicle and the refueling infrastructure.

InFord delivered 40 dedicated methanol fuel M Escorts to Los Angeles Countybut only four refueling stations were installed. Demonstration Ford Escape E85 flex-fuel plug-in hybrid. As an answer to the lack of refueling infrastructure, Ford began development of a flexible-fuel vehicle inand between andexperimental FFVs were built and delivered to California and Canada, including the 1.

As ethanol FFVs became commercially available during the late s, the common use of the term "flexible-fuel vehicle" became synonymous with ethanol FFVs. The CityCar is a plug-in hybrid concept car designed for flex-fuel operation on ethanolor methanol as well as regular gasoline.

In Europe, FFVs are also known as "flexifuel" vehicles.

The most common fuels used by FFVs today are unleaded gasoline and ethanol fuel. The VW Gol 1. This automobile was aimed at the taxicab market and the switch among fuels is done manually. Ethanol FFVs can run on pure gasoline, pure ethanol E or any combination of both.

This crisis opened a new opportunity for ethanol and other alternative fuelssuch as methanolgaseous fuels such as CNG and LPGand also hydrogen. Bi-fuel vehicles have the capability to switch back and forth from gasoline to the other fuel, manually or automatically.

The Siena Tetrafuel was engineered to switch from any gasoline-ethanol blend to CNG automatically, depending on the power required by road conditions. Ina new FFV Ford Taurus was developed, with models fully capable of running on either methanol or ethanol blended with gasoline.

However, cheaper oil caused gasoline to prevail, until the oil crisis resulted in gasoline shortages and awareness on the dangers of oil dependence. Byabout 50 percent of the gasoline used in the U.

Flexible-fuel vehicle

The success of this small experimental fleet of Ms led California to request more of these vehicles, mainly for government fleets.A flexible-fuel vehicle (FFV) or dual-fuel vehicle (colloquially called a flex-fuel vehicle) is an alternative fuel vehicle with an internal combustion engine designed to run on more than one fuel, usually gasoline blended with either ethanol or methanol fuel, and both fuels are stored in the same common flex-fuel engines are capable of burning any proportion of the resulting blend.

The MSc in Contemporary Alcohol & Drug Studies explores the interplay between psychoactive substances and society from a social science perspective.
