Magneti Marelli equips over 10 million vehicles in Brazil with Flex tech

October 15, 2012: Magneti Marelli has achieved a landmark in the Brazilian automotive market after having equipped more than 10 million vehicles with its SFS (Software Flexfuel Sensor). This number represents 67 percent of the nearly 15 million biofuel automobiles sold in Brazil since 2003, when the system was launched.

The data above refers to the total number of vehicles registered between 2003 and 2011, according to Anfavea (National Association of Automotive Vehicle Manufacturers). During this period, biofuel vehicles became the majority, and they currently account for 83 percent of all sales: a total of 1,402,672 units were sold from January to June of this year.

For the consumer, the main advantage of this solution is the possibility to choose the type of fuel with the best cost-benefit ratio and, in this case, ethanol serves as an alternative to petrol. Vegetable fuel, however, burns more thoroughly, reducing the amount of pollution released into the atmosphere. In March 2003, Magneti Marelli revolutionised the automobile market by launching the first flex fuel system, known as SFS which manages the burning of alcohol, petrol or any mixture thereof in the same engine. Consequently, drivers can choose which type of fuel to use.

SFS is an advanced software module fitted inside the electronic control unit of the car engine. This technology identifies and measures the mixture of alcohol and petrol in the fuel tank, using information received from sensors installed throughout the fuel injection system, including the lambda sensor, which is located in the exhaust system, and other sensors for combustion, revolution, speed and temperature.

Using this information, the program determines the amount of fuel to be injected in the engine and the instant that the spark plug should ignite to burn the fuel mixture. Biofuel systems in other countries require the use of an expensive physical sensor to conduct this type of analysis, something which the SFS does not require.

Magneti Marelli is currently the leader in the biofuel segment on the Brazilian market, and it supplies the system to Fiat, Ford, Mitsubishi and Volkswagen. The Italian supplier has been operating in Brazil since 1978, with a current staff of nearly 8,500 employees. It has a total of 11 production plants and five R&D centres in Brazil.
