摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control device for an internal combustion engine which can maintain the reliability of an addition valve by preventing the generation of a deposit around the addition valve.SOLUTION: An oxidation catalyst with a heater 6 is disposed at an upstream side of a fuel addition valve 5 in the exhaust emission control device where the fuel addition valve 5 is provided at an upstream side of an exhaust emission control unit 7. When a detected or estimated exhaust gas temperature exceeds a predetermined temperature, a heating operation by the oxidation catalyst with a heater 6 is not executed. When the exhaust gas temperature is equal to or lower than the predetermined temperature, the heating operation by the oxidation catalyst with the heater 6 is executed to raise the exhaust gas temperature. Consequently, a formic acid in the exhaust gas is decomposed and the generation of the deposit around the addition valve 5 is prevented.

摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission cleaning catalyst device and exhaust emission cleaning method for an internal combustion engine which has a wide range of cleaning temperature and shows a NOx cleaning rate higher than a certain rate over the substantially whole range. SOLUTION: A high temperature type catalyst 2 which has a high cleaning temperature range for nitrogen oxide cleaning and a low temperature type catalyst 3 which has a lower cleaning temperature range compared to the high temperature type catalyst 2 are serially arranged from the upstream side of an exhaust path. The distance L from the high temperature type catalyst 2 to the low temperature type catalyst 3 is set so that the upper limit temperature of the cleaning temperature range of the low temperature type catalyst 3 to the inlet gas temperature of the high temperature type catalyst 2 is higher than the temperature where a hydrocarbon cleaning rate of the high temperature type catalyst 2 shows 10% and lower than the temperature of where the rate is 80% or less. In the high temperature type catalyst 2, the portion of hydrocarbon of 10 or less carbon number in the exhaust gas in this temperature area increases, and since the low temperature type catalyst 3 shows satisfactory NOx cleaning performance in the presence of hydrocarbon of 10C or less, if the distance L between the catalysts is properly set, a gap between the cleaning ranges of both catalysts is eliminated and NOx cleaning rate is largely improved.

摘要： PURPOSE: To increase a HC amount meeting operating condition of an engine in an exhaust emission control system simply. CONSTITUTION: In a feed pump for supplying fuel to a fuel injection pump 1 by pressurizing fuel in a comparatively low pressure, the operating condition of an internal combustion engine, for example, it is noticed that feed pressure of fuel whose volume is changed according to rotating speed is generated. A part of fuel of feed pressure is taken out to a HC feed line 2 by a HC taking- out part 2a, pressure is regulated by a throttle 3, and it is supplied to a HC feed device 5 arranged upstream from an exhaust emission control system (for example, a catalyst). Exhaust purifying action is assisted as amount increasing HC by fuel which is mixed with exhaust gas and supplied to the exhaust emission control system 6. Since the amount of fuel supplied as HC is automatically regulated to a volume meeting operating condition of an engine, HC is supplied without the shortage even if complex means for regulating a HC feed amount especially is not used. A control valve 4 for opening/closing controlling by a simple control circuit 11 and an exhaust temperature sensor 7 are arranged.
