PROBLEM TO BE SOLVED: To suitably control fuel injection regardless of a situation of a throttle opening.SOLUTION: An engine control system (1) includes a fuel injection amount calculating section (33) for calculating a fuel injection amount on the basis of an estimated atmospheric pressure estimated from an intake pipe pressure by an atmospheric pressure estimating section (31) and engine speed detected by an engine speed sensor (6). The fuel injection amount calculating section compares the estimated atmospheric pressure estimated in starting of an engine with a learned atmospheric pressure stored in an atmospheric pressure storage section (32), and calculates the fuel injection amount with the usage of the learned atmospheric pressure when the difference between the estimated atmospheric pressure and the learned atmospheric pressure is smaller than a prescribed value, and calculates the fuel injection amount with the usage of the estimated atmospheric pressure when the difference between the estimated atmospheric pressure and the learned atmospheric pressure is equal to or larger than the prescribed value. |
