IGNITION TIMING CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To stable a combustion condition of an internal combustion engine without preventing rising a temperature of an exhaust gas emission control catalyst, in the case where a load amount an outside apparatus is changed when the temperature of the exhaust gas emission control catalyst is risen. SOLUTION: In this ignition timing control device for an internal combustion engine including a physical quantity in relation to a temperature of the exhaust gas emission control catalyst for purifying exhaust gas of the internal combustion engine and a load amount of an apparatus for applying a load on the internal combustion engine in a parameter for controlling the ignition timing of the internal combustion engine, control means (a step 1 to a step 8) for controlling the ignition timing of the internal combustion engine is disposed on the basis of a physical quantity in relation to the temperature of the exhaust gas emission control catalyst and a physical quantity in relation to an intake air amount corresponding to the sum of the load amounts of the apparatus.
