PURPOSE:To prevent worsening of emission of exhaust gas and to improve a fuel consumption, by a method wherein, after fuel is increased for control during the starting at a high temperature, when the average number of revolutions of an engine exceeds the set number of revolutions, an amount equivalent to an increase in fuel is gradually decreased. CONSTITUTION:When the temperature of cooling water and the temperature of intake air exceed a set value during idle running of an internal-combustion engine, an amount of fuel injected is increased for control to control an air-fuel ratio. After an amount of fuel injected is increased for control during the starting at a high temperature, when it is decided that the mean value of the number of an engine is increased to higher than the set number of revolutions, an amount, equivalent to an increase in said amount of fuel injected, is gradually decreased. This enables prevention of worsening of emission of exhaust gas and permits improvement of fuel consumption. |
