Title: Control device of internal combustion engine
Inventor: NOSE YUKI
IPC: F02D41/22
Filed: 2017-07-24
Abstract: To provide a control device of an internal combustion engine which can avoid the occurrence of a situation that the lowering of the control performance of combustion resulting from imbalance is promoted by dither control, and becomes conspicuous, or can suppress the situation compared with the case that the dither control is not limited.SOLUTION: When there arises a temperature rise requirement of a three-dimensional catalyst 24, a CPU 32 performs dither control for setting one of cylinders #1 to #4 to a rich combustion cylinder which is enriched in an air-fuel ratio more than a theoretical air-fuel ratio, and setting the remaining cylinders to lean combustion cylinders which are leaned in air-fuel ratios more than the theoretical air-fuel ratio. When the dither control is not performed, the CPU 32 learns a rich learning value being a learning value of a degree of rich imbalance on the basis of an upstream-side air-fuel ratio Afu. When the rich learning value is not smaller than a prescribed value, the CPU 32 prohibits the dither control.SELECTED DRAWING: Figure 1
