摘要: A control system of an internal combustion engine in which a catalyst device having oxidation ability is arranged in the exhaust system, is provided. When a temperature of the catalyst device is lower than a set temperature, the combustion temperature is made a first combustion temperature or under or is made a second combustion temperature or over, to make an amount of lower olefin in the exhaust gas smaller than that when the combustion temperature is higher than the first combustion temperature and is lower than the second combustion temperature. Therefore, an amount of lower olefin which reduces the oxidation rate of CO in the catalyst device is decreased so as to realize the quick warming-up of the catalyst device by using of the oxidation reaction heat of CO.

摘要: An exhaust purification system of an internal combustion engine which is controlled so that a combustion air-fuel ratio becomes lean at the time of ordinary operation, provided with an adsorption part which adsorb unburned fuel which is contained in exhaust gas and an oxidation part which has catalyst particles of a metal which oxidizes carbon monoxide. The adsorption part includes zeolite which substantially adsorbs the lower olefins which are contained in the exhaust gas. The adsorption part and the oxidation part are arranged so that the exhaust gas contacts the adsorption part, then contacts the oxidation part.

摘要: A wall flow type particulate filter is arranged inside the exhaust passage of an internal combustion engine where combustion is performed under an excess of oxygen. The particulate filter carries a solid acid. The solid acid has an acid strength which is higher than the acid strength of sulfurous acid and lower than the acid strength of sulfuric acid. To remove the ash from the particulate filter, ash atomization processing for rendering the state of the particulate filter a state where the exhaust gas which flows into the particulate filter is lowered in concentration of oxygen and the particulate filter is raised in temperature is temporarily performed.
