In an internal combustion engine of the present invention, an exhaust purification catalyst () and a hydrocarbon supply valve () are disposed in an engine exhaust path, and NOcontained in exhaust gas is purified by injecting hydrocarbon from the hydrocarbon supply valve () at a predetermined cycle. With respect to the injection amount per unit time of the hydrocarbon from the hydrocarbon supply valve (), there is a difference provided between the first half and the second half of one injection time period, and in the first-half injection time period (Y), the injection amount per unit time of hydrocarbon is made to be less as compared to the second-half injection time period (X).

Exhaust purification system of internal combustion engine

A method for purifying exhaust gas of an internal combustion engine, including chemically reducing NOx that is contained in the exhaust gas when a concentration of hydrocarbons flowing into an exhaust purification catalyst is made to vibrate within a predetermined range of amplitude and within a predetermined range of period, wherein, during the chemical reduction, the NOx contained in the exhaust gas is reacted with reformed hydrocarbons to produce a reducing intermediate containing nitrogen and hydrocarbons, a reducing action of the reducing intermediate chemically reduces the NOx, and the NOx is chemically reduced without storing nitrates or with storing a fine amount of the nitrates in a basic layer of the exhaust purification catalyst.

A three-way catalyst () having an oxygen storage function and an exhaust purification catalyst () are arranged in the exhaust passage of an internal combustion engine. During medium-load operation of the engine the degree of lean of the air-fuel ratio in the combustion chamber () is increased so as to increase the oxygen storage amount of the three-way catalyst () to the maximum oxygen storage amount, and the air-fuel ratio in the combustion chamber () even after the oxygen storage amount of the three-way catalyst () has reached the maximum oxygen, storage amount is maintained at lean, after which the air-fuel ratio is returned to rich, and at this time, as the amount of poisoning of a noble metal catalyst when the air-fuel ratio in the combustion chamber () is rich increases, the amount of time for which the air-fuel ratio in the combustion chamber () is maintained at lean is increased.

An internal combustion engine wherein an exhaust purification catalyst and hydrocarbon feed valve are arranged in an engine exhaust passage and wherein the NOwhich is contained in the exhaust gas is removed by injection of hydrocarbons from the hydrocarbon feed valve by a predetermined period. Hydrocarbons are injected from the hydrocarbon feed valve toward the upstream side of the engine exhaust passage.
