Document Type and Number:
Japanese Patent JP6993285
Kind Code:
B2
Abstract:
To provide a control device of an internal combustion engine which can effectively suppress the accumulation of deposits in a piston.SOLUTION: In a control device of an internal combustion engine for stopping oil injection when a rotational speed and a load rate of the internal combustion engine mounted to a vehicle belong to a stop region for stopping the oil injection to a piston from an oil jet, when a maximum value of an altitude difference in a traveling path in which a traveling frequency of the vehicle is high is equal to a threshold or larger, and when the fact that a vehicle speed of the vehicle belongs within a prescribed range, and an operation state of the internal combustion engine belongs to a prescribed high-rotation low-load region arises a prescribed number of times within a prescribed period, the stop region is expanded in an order of high-rotational speeds of the internal combustion engine.SELECTED DRAWING: Figure 3
