Peugeot has introduced flex-fuel versions of its popular 206 sedan and hatchback in Brazil. The cars run on either gasoline (already with 22% ethanol) or ethanol or any mixture of the two.
The new vehicles, promised in November 2004 at the ceremony to launch production of the Peugeot 206 SW at the Peugeot Porto Real plant in Brazil, represent the company’s first flex-fuel efforts in the country.
The 206 Nova Geração and SW flex-fuel models both use the 1.6-liter, 16-valve engine produced at Porto Real with a Bosch Motronic Flex Fuel injection system to handle the management of the different fuels.

The Bosch system measures the oxygen content in the exhaust fumes to determine the alcohol content in the fuel. The engine management software adjusts ignition and injection based on the actual fuel mix in the tank.
The diagram to the right illustrates the basic components of the system. A legend (Portuguese) is available here on the Bosch Brazil site.
Because the ignition properties of alcohol are inferior to gasoline when the engine is cold, the flex fuel system uses gasoline from a small 0.5 liter reserve tank for cold starts.
The Bosch system is not unique to Peugeot; the first car with Bosch flex fuel injection management as standard equipment was the VW Fox Total Flex, launched in 2003.
Peugeot is now the sixth automaker offering flex fuel cars in the country, joining Volkswagen, Fiat, Chevrolet, Ford and Renault. Peugeot will launch a Citroën C3 flex fuel model in the fall.
Peugeot has produced more than 4 million of the 206 model worldwide. The company will also begin producing the 206 in China this year, adding that country to France, Great Britain, Argentina, Brazil and Iran as production sites.
