Title:
CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2019/073815
Kind Code:
A1
Abstract:
In order to reduce vibration by suppressing fluctuation in combustion torque in an internal combustion engine and to prevent detracting from the driver's comfort, this control device of an internal combustion engine 100 comprising multiple cylinders 150 (a first cylinder 151, a second cylinder 152, a third cylinder 153, and a fourth cylinder 154) comprises a combustion state detection unit which detects whether the cylinders 150 are in a normal combustion state or a quenched state, and a control device 100 which controls driving of a combustion pump 131, which is a load on the combustion torque generated in the air cylinders 150. If it is determined that any of the air cylinders 151 to 154 of the air cylinders 150 is in a quenched state, the control device performs control so as to suppress driving of the fuel pump 131 at a prescribed combustion timing of the quenched-state air cylinders 151 to 154.
