The Bosch Flex Fuel System is capable of recognizing and adapt automatically the functions of management of the engine for any proportion of alcohol and gasoline mixture in the tank.

The identification of the mixture is made by the oxygen sensor (also known as Lambda Probe). After the fuel burning, Lambda Probe sends a signal to the command unit that starts the fuel recognition process, alcohol, gasoline or a mixture of them.

From this identification, beside the desire expressed by the driver via accelerator, the software of the command unit performs a comparison with the ideal points mapped. Thus it determines how de different components of the system must behave to generate the expected performance – having the lowest possible consumption and pollutants emission rates.
