摘要： PURPOSE:To remove combustible particles contained in the exhaust gas of an engine effectively, by providing an injector for injecting a catalytic solution and hydrochloric acid substantially simultaneously on the upstream side of a particulate filter, and burning combustible particles effectively even when the temperature of exhaust gas is low. CONSTITUTION:When the back pressure of an engine 1 becomes higher than a predetermined value due to clogging of a particulate filter 4, a pump 9 of an injecting means 5 is set into operation and a mixture liquid is injected from an injector 7 into an exhaust pasage 3 on the upstream side of the filter 4.

摘要： PURPOSE:To effectively raise the temperature of a reactor as well as to aim at a complete combustion of particle components, by throttling suction air in a specific cylinder and leading such exhaust gas as being raised in temperature and incresed in uncombustive components into the reactor, while bypassing the reactor to the exhaust gas in remaining cylinders. CONSTITUTION:When loading happens in a filter member 5, a control device 11 operates an on-off valve 7 and leads only the exhaust gas of a specific cylinder 1A into a reactor 4 by the help of an exhaust pressure sensor 12 and a temperature sensor 13, while throttles the quantity of suction air. As a result, in the reactor 4, the filter member 5 gets a temperature rise due to a rise in exhaust temperature and thereby reaction starting in an oxidation catalyzer is accelerated and simultaneously an increase in uncombustive components heightens the oxidation reaction of a catalyzer in consequence whereby reaction heat causes the temperature of the filter member 5 to go up further so that all sticking particles are removed in combustion. At this time, exhaust gas in those of remaining cylinders 1B-1D bypasses the reactor 4, reducing the flow rate of the reactor 4, thus a temperature rise in the filter member 5 takes place in an effective manner.
