Abstract
An exhaust purification system of an internal combustion engine includes a catalyst arranged in an exhaust passage of the internal combustion engine, a fuel supply device supplying fuel to the catalyst through the exhaust passage, and a control device configured to control the supply of fuel by the fuel supply device. The control device is configured to calculate a concentration in exhaust gas of fuel supplied to the exhaust passage by the fuel supply device and a saturation vapor pressure concentration of the fuel and supply fuel from the fuel supply device to the catalyst only when the concentration in the exhaust gas is higher than the saturation vapor pressure concentration.
