    • In the EGR system having an EGR control valve in an EGR passage, an orifice is provided on the exhaust side of the EGR control valve to define a negative pressure chamber between the EGR control valve and the orifice, and the pressure in the negative pressure chamber can be detected by a pressure-detector. When the operation state of the internal combustion engine is in a first operation zone wherein the amount of EGR is larger than a predetermined value, it is determined that clogging has occurred in the intake side EGR passage if the pressure value detected by the pressure-detector is smaller than a preset negative pressure value; while, it is determined that clogging has occurred in the exhaust side EGR passage if the pressure value detected by the pressure-detector is larger than the predetermined negative pressure value. An ON/OFF type pressure switch may be used as the pressure-detection means 17. As a result, it is possible to accurately detect the clogging position in the EGR passage without an increase in cost.

    • A trouble-detection apparatus for an EGR system provided with an EGR control valve in an EGR passage, capable of correctly detecting a position in the EGR passage at which the clogging has occurred. The trouble-detection apparatus is applied to the system having the EGR control valve controlled by a negative pressure in the EGR passage wherein a lift amount of the EGR control valve is controlled by a lift sensor in a feedback manner in accordance with the operating state of the engine. According to the trouble-detection apparatus, the amplitude of the lift amount detected by the lift sensor is obtained and the pulses in the exhaust-gas flow are calculated from the detected amplitude. When the amplitude of the pulses in the exhaust-gas flow does not reach a threshold value preset in accordance with the operating state of the internal combustion engine, it is determined that clogging as occurred in the EGR passage. In such a case, it is also possible to determine whether or not the clogging has occurred in the EGR passage by dividing the lift amount detected by the lift sensor into two subsystems, extracting solely a pulse component therefrom, calculating an amplitude of the extracted pulse component, and comparing the calculated amplitude with a threshold value.

    • An exhaust state control device for a fuel cell for a mobile unit includes an exhaust gas temperature sensor (17) that measures the temperature of exhaust gas in a discharge passage that discharges the exhaust gas from the main body of the fuel cell, and an ambient temperature sensor (19A) that measures the temperature of ambient air to which exhaust gas is to be discharged. If, based on the difference between the exhaust gas temperature and the ambient temperature, it is determined that white smoke is generated, it is determined whether a condition to reduce white smoke is satisfied. When a first condition is satisfied, a process to reduce white smoke is activated. When a second condition, which requires further reduction of white smoke than under the first condition, is satisfied, a process to suppress the generation of white smoke is activated.
