Disclosed is a counterflow control exhaust port of an internal combustion engine, which is coupled to a tailpipe through which a combustion gas of the internal combustion engine is discharged so as to prevent the outside air from flowing into an exhaust system according to pressure difference after discharging the combustion gas, thereby reducing exhaust impedance, and controlling the outside air flowing backward so as to increase an exhaust gas discharge speed, and thus, combustion efficiency improvement, output power enhancement, and smoke reduction effects can be expected. |
