A control method of a direct-injection internal combustion engine that switches an injection count of multiple-stage injection according to an operating region and performs the multiple-stage injection, the multiple-stage injection being configured to divide fuel into multiple times in one combustion cycle and inject the fuel, - the control method comprising: - supplying fuel vapor generated in a fuel tank as evaporated fuel to the internal combustion engine; and - narrowing an operating region in which the injection count of the multiple-stage injection is large when an amount of the evaporated fuel supplied to the internal combustion engine is large, compared with a case where the amount of the evaporated fuel is not large, - wherein: - the amount of the evaporated fuel supplied to the internal combustion engine is determined to be large when the amount of the evaporated fuel exceeds a predetermined threshold and - the threshold is an amount of evaporated fuel at which an injection pulse width of each injection after the amount of fuel injection is corrected according to the amount of evaporated fuel without changing the injection count of the multiple-stage injection becomes a minimum injection pulse width, the control method being characterised by: increasing the multiple-stage injection count in a case where the amount of the evaporated fuel supplied to the internal combustion engine is large and a combustion chamber temperature is in a low-temperature state lower than a predetermined temperature, compared with a case where the amount of the evaporated fuel supplied to the internal combustion engine is large and the combustion chamber temperature is equal to or higher than the predetermined temperature. - the control method comprising: - supplying fuel vapor generated in a fuel tank as evaporated fuel to the internal combustion engine; and - narrowing an operating region in which the injection count of the multiple-stage injection is large when an amount of the evaporated fuel supplied to the internal combustion engine is large, compared with a case where the amount of the evaporated fuel is not large, - supplying fuel vapor generated in a fuel tank as evaporated fuel to the internal combustion engine; and - narrowing an operating region in which the injection count of the multiple-stage injection is large when an amount of the evaporated fuel supplied to the internal combustion engine is large, compared with a case where the amount of the evaporated fuel is not large, - wherein: - the amount of the evaporated fuel supplied to the internal combustion engine is determined to be large when the amount of the evaporated fuel exceeds a predetermined threshold and - the threshold is an amount of evaporated fuel at which an injection pulse width of each injection after the amount of fuel injection is corrected according to the amount of evaporated fuel without changing the injection count of the multiple-stage injection becomes a minimum injection pulse width, the control method being characterised by: increasing the multiple-stage injection count in a case where the amount of the evaporated fuel supplied to the internal combustion engine is large and a combustion chamber temperature is in a low-temperature state lower than a predetermined temperature, compared with a case where the amount of the evaporated fuel supplied to the internal combustion engine is large and the combustion chamber temperature is equal to or higher than the predetermined temperature. - the amount of the evaporated fuel supplied to the internal combustion engine is determined to be large when the amount of the evaporated fuel exceeds a predetermined threshold and - the threshold is an amount of evaporated fuel at which an injection pulse width of each injection after the amount of fuel injection is corrected according to the amount of evaporated fuel without changing the injection count of the multiple-stage injection becomes a minimum injection pulse width, the control method being characterised by: increasing the multiple-stage injection count in a case where the amount of the evaporated fuel supplied to the internal combustion engine is large and a combustion chamber temperature is in a low-temperature state lower than a predetermined temperature, compared with a case where the amount of the evaporated fuel supplied to the internal combustion engine is large and the combustion chamber temperature is equal to or higher than the predetermined temperature.
