Abstract (en)
[origin: US5101791A] A method and apparatus regulate and control the running smoothness of an internal combustion engine. Based on the existing operating conditions, either a running-smoothness regulation or a running-smoothness control is performed. If the vibrational frequency of the engine or the system deviation thereof reaches a threshold value, or if the absolute value of the system deviation is greater than the threshold value, then the running-smoothness regulation is ceased.
