ABSTRACT:
A vibration suppression system for a diesel engine, comprises a device for decreasing the amount of intake air to be inducted into the engine when operated. A heating device is provided to heat the intake air when operated. A first detecting device is provided to detect a low engine speed and low engine load operating range of the engine, to produce a first signal in response thereto. A second detecting device is provided to detect the level of vibrational acceleration of engine vibration having frequencies within a predetermined range, and to produce a second signal in response thereto. First and second control devices are provided respectively operate the intake air amount decreasing device in response to the first signal and the heating device in response to the second signal, thereby throttling intake air in the low engine speed and low engine load operating range while heating intake air when the vibration acceleration level is outside a predetermined allowable range.
