Title:
CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2022035736
Kind Code:
A
Abstract:
To provide a control device of an internal combustion engine capable of further reducing difference between output torque in a single turbo mode and output torque in a twin turbo mode by more simple processing, in controlling the output torque to the target torque in a turbo switching region in which both of the single turbo mode and the twin turbo mode can be applied, in the internal combustion engine having two turbo chargers.SOLUTION: As operation regions of an internal combustion engine, one-turbo region of a single turbo mode, two-turbo regions of a twin turbo mode, and a turbo switching region in which the turbo mode is switched between the one-turbo region and the two-turbo regions, are determined, and in the turbo switching region, an injection amount in the single turbo mode and an injection amount in the twin turbo mode are different from each other to reduce the difference between the output torque in the single turbo mode and the output torque in the twin turbo mode.SELECTED DRAWING: Figure 13
