And / or parameters related to the burning rate of the accumulated unburned components (for example, engine water temperature or exhaust temperature).

- the condition for canceling the suppression of the fuel supply may be any one of the suppression time tc has passed (S30) and the glow temperature Tg has fallen below the upper limit temperature Ta (S50).
- the present embodiment further includes an exhaust temperature sensor 18 for acquiring the temperature of the exhaust passage, and the fuel supply time ts, which is the temperature increase execution time, is shorter as the exhaust temperature Te is higher, and the fuel supply amount Qf. Since it is shorter as there is more, deterioration of the glow plug 15 can be suitably suppressed by suppressing excessive temperature rise.
- the tip of the injector 12 and the glow plug 15 can be quickly cooled (after t3 in FIG. 4). Only one of the after addition and the increase of the exhaust flow rate may be performed. The increase in the exhaust flow rate may be started immediately before the glow plug 15 is energized (S20). In this case, the combustion is performed downstream of the tip of the glow plug 15 to increase the temperature at the tip. Can be suppressed.
- the ECU 30 does not supply fuel from the injector 12 for a predetermined suppression time tc including the start of the heating operation of the glow plug 15 (S30).
- the amount of fuel reduced may be reduced during the suppression time tc compared to the fuel supply performed in step S90.
- the fuel supply time ts is set as a function of the exhaust temperature Te and the fuel supply amount Qf, but may be a function of only one of them.
