PROBLEM TO BE SOLVED: To prevent feeding of a larger quantity of fuel than necessary, preventing generation of black smoke at the start of an engine by setting the minimum necessary quantity of initial fuel supply 4-2 adaptable for the environmental change or mechanical secular change of the engine. SOLUTION: When the engine is started, the quantity of initial fuel supply 4-1 is decided based on a temperature-fuel supply quantity map. When the start of the engine is not completed, the quantity of fuel supply is gradually increased (5). Then, when the start of the engine is completed, the temperature-fuel supply quantity map is modified. The new quantity of initial fuel supply 4-2 is made to be smaller than the quantity of fuel supply 6 at the completion of the start of the engine by a prescribed value under the previous condition of temperature of the start of the engine. At the next start of the engine, the quantity of initial fuel supply 4-2 is decided based on the modified temperature-fuel supply quantity map.
