There is a time lag before getting. In addition, even when the driver's foot is simply released from the brake pedal and the vehicle is gradually started, especially when the vehicle 12 includes an automatic transmission, the engine 10 is returned to the state immediately before the engine is stopped.

- the valve 52 is switched to the engine operable position, that is, the valve position I or the valve position II, and the air whose pressure is increased by the compressor 28 is quickly supplied to the engine main body 14. Therefore, the start-up at the restart of the engine 10 can be accelerated, and the operation response of the engine 10 can be enhanced.
- the power generation device 40 is operated, so that the exhaust gas from the power generation device 40 flows into the exhaust purification device 36. Therefore, even when the engine is stopped by the idle reduction control, the exhaust gas purification device 36 can warm up the catalyst. Therefore, the engine stop by the idle reduction control can be allowed even when it is cold.
- the configuration of the engine according to the second embodiment of the present invention and the vehicle on which the engine is mounted are substantially the same as the configuration of the engine 10 according to the first embodiment and the vehicle 12 on which the engine 10 is mounted.

This has already been explained.
- the predetermined restart condition in the idle reduction control is satisfied when any of the predetermined stop conditions is not satisfied as described above. For example, when the engine 10 is stopped by the system 84, when the brake operation is released, or when the accelerator pedal is depressed, it is determined that a predetermined restart condition is satisfied. And when the accelerator pedal is depressed, the time when there is a request for acceleration is included.
- steps S401 to S405 and S409 in the flowchart of FIG. 4 generally correspond to steps S201 to S207 of the flowchart of FIG. Therefore, the description of these steps can be largely omitted below.
- step S401 If an affirmative determination is made in step S401 that a predetermined stop condition has been established, the engine 10 is stopped in step S403, and the power generation apparatus 40 enters an operating state. At this time, the fuel supply device 48 of the power generation device 40 operates so that the fuel supply amount becomes the first amount.
- the valve 32 is basically closed. Therefore, the amount of power generated by the power generation device 40 and the amount of gas discharged from the power generation device 40 at this time are determined by the amount of fuel supplied to the fuel cell main body 42. Therefore, here, when the power generation device 40 operates in step S403, in the power generation device 40, the fuel supply is controlled by the portion that functions as a discharge amount increasing means of the ECU 70. In particular, here, based on the output of the air flow meter 72, the fuel supply amount is controlled to the first fuel amount so that the gas discharge amount from the power generation device 40 becomes the first discharge amount.

- a predetermined restart condition is established when the driver removes his / her foot from the brake pedal (affirmative determination in step S405). Immediately thereafter, or within a predetermined period from the time when the driver is satisfied, the driver depresses the accelerator pedal. It is also possible to determine in step S407 that there is an acceleration request even when the accelerator opening becomes larger than a predetermined value by stepping on or when the accelerator opening changing speed is larger than a predetermined amount. Thus, when it is determined that there is an acceleration request, the case where the engine 10 is not in a stopped state is included. This is because turbo lag may occur even when there is an acceleration request within a predetermined period after a predetermined restart condition is established.
- the predetermined period is a period in which turbo lag is expected to occur, and may be set by experiment. This predetermined period can be measured by a portion that functions as a timer means of the ECU 70.

- the part responsible for the function of the emission increase control means of the ECU 70 increases the fuel supply amount in the power generation device 40 from the first fuel amount to the second fuel amount larger than the first fuel amount. Therefore, the amount of gas discharged from the gas discharge passage 50 of the power generation device 40 becomes a second discharge amount that is larger than the first discharge amount when the first fuel amount of fuel is supplied to the power generation device 40.
- step S411 the valve 52 is controlled to the engine operable position.
- the valve 32 when the predetermined stop condition is satisfied, the valve 32 is substantially closed. After that, when there is an acceleration request and the predetermined restart condition is satisfied, the generator 40 The amount of fuel was increased compared to when there was no acceleration request. However, when there is an acceleration request by other control, the amount of gas discharge may be increased.
- the valve 32 when a predetermined stop condition is satisfied, the valve 32 can be controlled to be opened to a predetermined opening (not a closed opening) in step S403.
- the valve 32 may be an electromagnetically driven valve.
- the valve 32 or the valve mechanism 28 is completely closed as the discharge amount increase control, and the amount of air supplied to the air introduction passage 44 is increased. (Air supply increase control).

- the drive mechanism 126c includes a motor whose operation is controlled by the ECU 70. Therefore, in the turbocharger 124, the supercharging pressure can be adjusted by adjusting the nozzle opening degree of the variable nozzle mechanism 126a. Note that during normal travel, the nozzle opening of the variable nozzle mechanism 126a is controlled by a portion serving as a nozzle opening control means of the ECU 70 based on at least one of the engine rotation speed and the engine load.
- an acceleration request is issued when a predetermined restart condition is satisfied or within a predetermined period after the predetermined restart condition is satisfied.
- control is performed to make the operation response of the engine 10 different from that when there is no acceleration request. Such control will be described below based on the flowchart of FIG.
- steps S601 to S611 in the flowchart in FIG. 6 correspond to steps S401 to S411 in the flowchart in FIG. 4 respectively except for parts of steps S603 and S611. Therefore, in the following, the control of the third embodiment will be described by paying attention to the difference between the steps while partially omitting the overlapping description.

That is, in this case, the engine 110 is restarted in a state where the nozzle opening of the variable nozzle mechanism 126a is set to the first opening and the power generation apparatus 40 is operated. Therefore, the operation response of the engine 10 is based on the supercharging effect by the turbocharger 124 corresponding to the third emission amount gas corresponding to the nozzle opening.
- step S611 since there is an acceleration request, when an affirmative determination is made in step S607, the engine 110 is restarted in step S611 with the emission increase control.

- the fuel supply amount at 40 is also controlled to increase. Therefore, the amount of gas discharged from the gas discharge passage 50 of the power generation device 40 becomes larger than when the nozzle opening of the variable nozzle mechanism 126a is set to the first opening.
- the supercharging effect at the engine 110 by the turbocharger 124 can be enhanced. Therefore, the operation response of the engine 110 can be improved when the engine 110 is restarted at step S611 than when the engine 110 is restarted at step S609.
- step S611 as in step S609, the valve 52 is controlled to the engine operable position.
- the power generation device 40 continues to operate at least until the restart of the engine 110 is completed when an acceleration request is made (Yes in step S607).
