Abstract
When the temperature in a cylinder of an engine is low, the fuel injection amount of fuel that has a low vapor pressure and is less likely to be vaporized is increased, and the fuel injection amount of fuel that has a high vapor pressure and is more likely to be vaporized is reduced, so that the start timing of the engine can be kept constant. When the temperature in the cylinder is high, the fuel injection amount of the fuel that has a low vapor pressure and is more likely to be decomposed is reduced, and the fuel that has a high vapor pressure and is less likely to be burned (decomposed) is increased, so that the start timing of the engine can be kept constant. Thus, the start timing of the engine is kept constant irrespective of the fuel property, and deterioration of the drivability can be curbed.
