ABSTRACT:
It is determined whether an engine for a flexible fuel vehicle is in a start enabling state based on alcohol concentration of fuel supplied to the engine. When it is determined that the engine is in the start enabling state, a heater for vaporizing fuel is energized. Current flowing in the heater is compared with a reference current representing completion of warmup of the engine. When the current becomes smaller than the reference current, the heater is de-energized, and the fuel is injected to start the engine.
