ABSTRACT:
A start control apparatus for an internal combustion engine, which takes an amount of a fuel vaporized from a heated fuel into consideration to prevent deterioration of startability due to an overrich or overlean condition caused by an excessive or insufficient amount of the vaporized fuel and to realize improvement of cold startability. The start control apparatus includes: a heater (14) for heating a fuel to be supplied to the internal combustion engine; fuel heating control unit (22) for energizing the heater when a cooling water temperature is less than an internal combustion engine start possible water temperature value to heat the fuel; and start time fuel setting unit (26) for setting a start time fuel injection amount of the internal combustion engine according to a fuel temperature after the fuel is heated by the fuel heating control unit (22), an alcohol concentration, and the cooling water temperature.
