摘要： An exhaust gas purifying device of the invention comprises an exhaust gas purifying catalyst (20) disposed in an exhaust system, a fuel adding device (28) for adding fuel to the exhaust gas purifying catalyst (20) as a reducing agent, a fuel supplying source (6) for supplying the fuel adding device (28) with fuel, an emergency shut-off valve (31) disposed in a fuel supplying passage (29) that connects the fuel supplying source (6) to the fuel adding device (28), and a shut-off valve position detecting means for detecting that the emergency shut-off valve (31) is closed. If an upstream fuel pressure applied to the emergency shut-off valve (31) becomes higher than a downstream fuel pressure applied to the emergency shut-off valve (31), the emergency shut-off valve (31) is controlled so as to be prevented from being opened. If the exhaust air-fuel ratio does not shift to the rich side despite the issuance of an instruction to add fuel at this moment, it is possible to detect that fuel leakage has occurred downstream of the emergency shut-off valve (31).

摘要： An internal combustion engine 1 is capable of switching, during engine operation, between a low-temperature combustion state in which an intake air with a high EGR rate is burned to operate the engine, and a normal combustion state in which an intake air with a low EGR rate is burned to operate the engine. In the internal combustion engine (1), a pilot injection is executed in addition to a main fuel injection, and furthermore the execution of the pilot injection is restricted during the engine operation with a combustion state switched to the low-temperature combustion state.

摘要： The heater (28) heats the NOx catalyzer (20) to establish a target temperature based on the mode of operation of the engine as detected by the detector (33, 36). The heater does not heat the NOx catalyzer if the engine is running at high load when it is not appropriate to heat the NOx catalyzer. Apparatus for controlling the emission from an internal combustion engine (1). This comprises a NOx catalyzer (20) which adsorbs and accumulates the NOx from the exhaust gases flowing in the NOx catalyzer if the air/fuel ratio is poorer than the stoichiometric ratio and which releases the NOx when the air/fuel ratio is the same as or richer than the stoichiometric ratio. A heater (28) heats the NOx catalyzer if it is necessary to suppress the sulfur oxides in the NOx catalyzer; and means of detecting the state of operation (33, 36) of the internal combustion engine. If it is necessary to suppress the sulfur oxide in the NOx catalyzer, the heater temporarily raises the temperature of the NOx catalyzer to the temperature required for recovery from sulfur poisoning and, if the recovery has not been achieved by a final preset time, the heater heats the NOx catalyzer to a target temperature based on the state of operation of the engine detected by the detector and, if the engine is in an operating state during which heating is not appropriate, the heater stops heating the NOx catalyzer. The target temperature of the catalyzer is made higher if the engine is operating with low load than if the engine is operating with high load. The command to turn on the heater is weakened if the real temperature of the catalyzer is higher than the target temperature and strengthened if the real temperature of the catalyzer is below the target temperature. The heater stops if the engine's mode of operation does not allow suppression of sulfur oxide to occur during a preset time while the heater heats the catalyst. An Independent claim is also included for process for using the apparatus, where the mode of operation of the engine is detected, a target temperature for the NOx catalyzer is established based on the mode of operation and the NOx catalyzer is heated to the target temperature or the heating is stopped if the engine is operating with high load when it is not appropriate to heat the NOx catalyzer.
