Abstract
A vibration suppression system for a diesel engine comprises a first device for decreasing the amount of intake air to be inducted into the engine when operated. A second device is provided to heat the intake air when operated. Additionally, a third device is provided to detect a low engine speed and low engine load operating range, and to produce a signal in response thereto. The first and second devices are operated in response to the signal from the third device, thereby avoiding irregular combustion and misfire while suppressing engine speed fluctuation and torque fluctuation.
