As ethanol shows lower inflammability below 13 °C, Bosch has developed the Flexstart system, which heats up the fuel in the starting phase. The heating control unit is part of the Flexstart technology. A smooth start of the engine is guaranteed even at low temperatures due to the fuel being heated up, especially for E85 - E100.
