<p><P>PROBLEM TO BE SOLVED: To properly control operation of an internal combustion engine on the basis of a fuel cetane number. <P>SOLUTION: The internal combustion engine control device (100) includes: a cetane number detection means (110) that detects cetane number of the fuel to be used for the internal combustion engine (200) at a predetermined timing; an angular velocity detection means (120) that detects an angular velocity of a crankshaft (204) of the internal combustion engine; a filtering means (130) that filters an output value of an detected angular velocity; a separation amount calculation means (140) that calculates a separation amount between the filtered output value and a predetermined output value; a correction means (150) that corrects the cetane number detected depending on the calculated separation amount; and a control means (160) that controls the operation of the internal combustion engine based on the corrected cetane value. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
