An engine ECU executes a program including the steps of: calculating an in-cylinder injector's injection ratio (S100); if the ratio is 1, calculating a cold state increase value by employing a function f(1) having the engine's temperature as a parameter (S120); if the ratio is 0, calculating a cold state increase value by employing a function f(2) having the engine's temperature as a parameter (S130); and if the ratio is larger than 0 and smaller than 1, calculating a cold state increase value by employing a function f(3) having the engine's temperature and the ratio as parameters (S140).
