CONTROLLING DEVICE OF INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To provide a controlling device of an internal combustion engine capable of preventing starting failure of an engine and deterioration of an exhaust performance by over lean or over rich due to an inefficient correction volume of an air/fuel ratio. SOLUTION: When a kind of fuel in a fuel tank might be changed, a range of a volume for correcting the air/fuel ratio capable of correcting the fuel injection volume is enlarged in comparison with a normal time (when a kind of fuel in the fuel tank might not be changed) from the time when it is judged to change the kind of the fuel till a single component density of the fuel is estimated.
