  "textContent": "An engine control system capable of appropriately controlling fuel injection, irrespective of situations of a throttle opening degree, is provided. A engine control system 1 includes a fuel injection amount calculation unit 33 configured to calculate a fuel injection amount based on an estimated atmospheric pressure estimated from an intake pipe pressure by an atmospheric pressure estimation unit 31 and an engine rotation number detected by an engine rotation number sensor 6. The fuel injection amount calculation unit is configured to compare the estimated atmospheric pressure estimated upon engine start and a learning atmospheric pressure stored in an atmospheric pressure storage unit 32, and calculates a fuel injection amount by using the learning atmospheric pressure when a difference between the estimated atmospheric pressure and the learning atmospheric pressure is smaller than a predetermined value and calculates a fuel injection amount by using the estimated atmospheric pressure when the difference between the estimated atmospheric pressure and the learning atmospheric pressure is equal to or larger than the predetermined value.",
