Title:
CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2018009502
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine which can suitably suppress the generation of a piston hammering sound.SOLUTION: A control device 40 comprises an engine rotation number acquisition part 41 for acquiring a rotation number of an internal combustion engine 10, and an engine load acquisition part 42 for acquiring a load of the internal combustion engine 10. The control device 40 comprises a cooling water temperature acquisition part 43 for acquiring a temperature of cooling water in a water jacket 25, and an oil temperature acquisition part 44 for acquiring a temperature of oil injected toward a piston 19 by an oil jet device 30. The control device 40 comprises an oil/water temperature difference calculation part 45 for calculating a temperature difference between a temperature of the cooling water and a temperature of the oil, and an ignition timing control part 46 for retarding ignition timing rather than reference ignition timing on the basis of a first value and a second value. The ignition timing control part 46 calculates the first value for largely retarding the ignition timing as combustion pressure is high, and the second value for largely retarding the ignition timing as the oil/water temperature difference is large.SELECTED DRAWING: Figure 1
