Abstract
In the disclosed embodiments, a fuel supply system for an internal combustion engine operating on alcohol-containing fuel has a fuel pump and a cold-starting device for injecting an auxiliary fuel into an air-fuel intake line of the engine. A control unit controls the operation of the cold-start device when the temperature is lower than a predetermined lower temperature limit and the actuation time is adjustable as a function of temperature. The actuation time of the cold-start device is also controllable as a function of the alcohol content of the fuel.
