Title:
CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2017008796
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To properly keep rotation of an internal combustion engine by adjusting an air intake amount filled in a cylinder by properly increasing and decreasing the same.SOLUTION: A control device of an internal combustion engine is constituted to repeatedly measure a time necessary for an output shaft of an internal combustion engine to rotate by a first prescribed angle to determine variation of a rotating speed in the rotation of the output shaft by the first prescribed angle, to repeatedly measure a time necessary for the output shaft of the internal combustion engine to rotate by a second prescribed angle larger than the first prescribed angle to determine variation of a rotating speed in the rotation of the output shaft by the second prescribed angle, and to determine an increase/decrease amount of the intake air to be filled in the cylinder, in reference to the small one of the former variation and the latter variation.SELECTED DRAWING: Figure 3
