PROBLEM TO BE SOLVED: To promote discharge of condensation water and melting of frozen condensation water in an exhaust pipe.SOLUTION: An engine control system includes: a throttle motor 34 for controlling a flow rate per unit time of exhaust gas discharged from an engine; and an engine ECU 12 for controlling the throttle motor 34 so that the flow rate becomes higher than that in a predetermined normal state from start of the engine until predetermined second time passes, when a temperature below zero is detected by an outside air temperature sensor 16 for detecting an outside air temperature and previous engine operation time is shorter than predetermined first time.SELECTED DRAWING: Figure 1 |
