摘要： An internal combustion engine is configured in such a manner that an exhaust gas purification catalyst (13) and a hydrocarbon supply valve (15) are provided in an exhaust gas passage. An exhaust gas purification device selectively uses: a first NOx purification method in which hydrocarbon is sprayed from the hydrocarbon supply valve at predetermined intervals, purifying NOx contained in exhaust gas; and a second NOx purification method in which the air-fuel ratio of exhaust gas which flows into the exhaust gas purification catalyst is made rich at intervals longer than the predetermined intervals, causing the exhaust gas purification catalyst to release occluded NOx and cleaning the NOx. It is determined whether or not the exhaust gas purification catalyst is clogged with the deposition of particulates in the exhaust gas. When it is determined that the exhaust gas purification catalyst is clogged, the second NOx purification method is used.

摘要： In order to supply a reducing agent to two NOx catalysts arranged in series in an appropriate manner, normal control in which an additive agent of an amount according to an amount of NOx flowing into an upstream side NOx catalyst is added from an upstream side of the upstream side NOx catalyst, and decrease control in which when an amount of ammonia adsorbed to a downstream side NOx catalyst exceeds a predetermined upper limit amount in cases where the two NOx catalysts have been activated, an amount of additive agent to be added from a first addition device is made smaller than the amount of additive agent to be added at the time of the normal control, are carried out.

摘要： An exhaust gas control system includes an upstream purification device (50, 50a, 50b) disposed in an exhaust passage (5, 5a, 5b, 5a', 5b') of the internal combustion engine (1), a downstream purification device (51, 51a, 51b) disposed in a portion of the exhaust passage downstream from the upstream purification device, a fuel addition valve (52, 52a, 52b) disposed in a portion of the exhaust passage upstream from the upstream purification device, and a urea addition valve (53, 53a, 53b) disposed in a portion of the exhaust passage between the upstream purification device and the downstream purification device, and a cooling device. The cooling device is configured such that refrigerant cools the fuel addition valve first and then cools the urea addition valve subsequent to the fuel addition valve.

摘要： When it is determined that there is a possibility of start-up of an internal combustion engine (11) while regeneration control is in execution during stop of the internal combustion engine (11), processing of the regeneration control is stopped. Accordingly, as compared with the case where the regeneration control is continuously executed when the internal combustion engine (11) is started up, temperature increase in a filter (13) can be suppressed. Therefore, even when an increased amount of oxygen is supplied to the filter, an oxidation reaction is suppressed, so that overheating of the filter (13) can be suppressed.
