Not only during running of a vehicle, but even when a diesel engine 1 is stopped at the time of starting up the vehicle or during braking control of the vehicle and when an output of the diesel engine 1 is reduced during coasting of the vehicle, a propeller fan 8 of a radiator 7 is forcibly driven to generate a wind sound caused by the propeller fan 8.</p> |
