    摘要： In an exhaust gas purifying technique in which discharge is utilized, the invention provides a technique in which purification efficiency can be enhanced while an increase in electric power consumption is suppressed. A discharge mode including a discharge period and an undischarged period is adopted in a configuration in which a plasma process is performed to exhaust gas from a Diesel engine by generating the discharge in a plasma generator. A basic waveform periodically exists in a repeated manner in the discharge period, and the discharge is not performed in the undischarged period. An amplitude and/or a period of the basic waveform is controlled according to a load on the Diesel engine, a continuous iteration count of the basic waveform is controlled according to purification reaction efficiency in the plasma process, and the burst period is controlled according to an exhaust gas flow rate.

    摘要： Provided is a DPF failure detection device not only capable of a quick detection but also having less erroneous and a small power consumption. The DPF failure detection device, after starting applying a dust collecting voltage to a dust collecting electrode, applies a measuring voltage to a measuring electrode while the dust collection voltage is being applied, thereby measuring the capacitance of a sensor device. The DPF failure detection device also stops applying the dust collecting voltage to the dust collecting electrode in response to the fact that the measured value (CCOL) of this capacitance exceeds a completion criterion (CCOL—TH). Further, the DPF failure detection device applies the measuring voltage to the measuring electrode, thereby measuring the capacitance of the sensor device and obtaining a measured value (CPM), on the basis of which a DPF failure is determined.
