Title: Engine control device
Inventor: HANAI NORIHITO
IPC: F02D41/22
Filed: 2019-07-31
Abstract: To suppress the generation of knocking after a determination of rich imbalance.SOLUTION: An engine control device performs lean active control for commanding a cylinder under rich imbalance determination to inject fuel in an amount smaller than that of other cylinders, and determines whether or not the rich imbalance occurs in the cylinder under determination on the basis of a rotation variation amount of a crank shaft during the lean active control. Also, during the execution of the lean active control at times t1 to t2, the engine control device limits an advance of ignition timing by knock control. By this constitution, since a frequency of the generation of knocking is reduced with the execution of the lean active control, an excessive advance of ignition timing can be prevented. Therefore, when the determination of rich imbalance is finished and an air-fuel ratio of the cylinder under determination is returned to a stoichiometric state, the generation of knocking can be prevented.SELECTED DRAWING: Figure 7
