Title:
CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2019138263
Kind Code:
A
Abstract:
To suppress the generation of knocking.SOLUTION: A control device 200 of an internal combustion engine 100 comprises: an electrode part flow speed calculation part for calculating an electrode part flow speed being a flow speed of a tumble flow passing an electrode part 12a while flowing to a direction progressing toward an exhaust port 32 side from an intake port 31 side along an apex face of a combustion chamber 7; a determination part for determining whether or not a flow direction of the tumble flow becomes a reverse direction progressing toward the intake port 31 side from the exhaust port 32 side on the basis of the electrode part flow speed; and a fuel injection control part for injecting fuel from a fuel injection valve 21 at prescribed timing at an advance side rather than the ignition timing of an ignition plug 12 so that the flow direction becomes a direction progressing to the exhaust port 32 side from the intake port 31 side when it is determined that the flow direction of the tumble flow becomes the reverse direction. The fuel injection control part increases an injection amount or the injection pressure of the fuel which is injected from the fuel injection valve 21 compared with the case that the electrode part flow speed in the reverse direction progressing to the intake port 31 side from the exhaust port 32 side is low when the electrode part flow speed is high.SELECTED DRAWING: Figure 1
