ABSTRACT:
In a transient state, where the temperature at the distal end of a fuel adding valve enters a high temperature region, an addition amount for preventing clogging is not simply added in accordance with a map, but instead, delay in the rise of the temperature of the fuel adding valve in the transient state is taken into consideration, and the addition amount for preventing clogging is calculated on the basis of the elapsed time after the point in time when the temperature at the distal end of the fuel adding valve enters the distal end high temperature region and the drive state of the engine (for example, the number of rotations of the engine), and thus, addition is carried out (steps ST4to ST6). Such addition control makes it possible to add an appropriate fuel addition amount for the rise in temperature of the fuel adding valve in the transient state, and thus, wasteful fuel addition is reduced.
