摘要： It is checked whether or not a supercharged pressure Pb becomes equal to or greater than a predetermined value P0 to judge whether or not a mechanism for adjusting the supercharged pressure is failed. When it is judged that the mechanism for adjusting the supercharged pressure is not failed, the fuel injection quantity Tp of normal time is computed based upon the engine operation condition. When it is judged that the mechanism for adjusting the supercharged pressure is failed, on the other hand, the fuel injection quantity Tp of failed time is computed, which is smaller than the fuel injection quantity of normal time. The fuel injection is then controlled based upon either the computed fuel injection quantity Tp of normal time or the computed fuel injection quantity Tp of failed time. In case the mechanism for adjusting the supercharged pressure is failed, therefore, the fuel injection quantity is decreased to decrease the torque that is produced, to thereby control the supercharged pressure to be less than an allowable upper limit.
摘要翻译：检查增压压力Pb是否等于或大于预定值P0，以判断增压压力调节机构是否失败。当判断为增压压力调整机构未发生故障时，基于发动机运转状态来计算正常时间的燃料喷射量Tp。另一方面，当判断为增压压力调整机构发生故障时，计算失效时间的燃料喷射量Tp小于通常时间的燃料喷射量。然后基于正常时间的计算燃料喷射量Tp或计算出的失效时间的燃料喷射量Tp来控制燃料喷射。因此，在调整增压压力的机构故障的情况下，燃料喷射量减少，减少产生的转矩，从而将增压压力控制在容许上限以下。

摘要： A diesel particulate filter (14) which traps particulate matter and a NOx trap catalyst (13) which traps nitrogen oxides are installed in series in an exhaust passage (10) of a diesel engine (1). A controller (21) calculates a particulate matter deposition amount in the diesel particulate filter (14) (S4). The controller (21), when the particulate matter deposition amount exceeds a first predetermined amount (PM2), prevents sharp increase of the particulate matter deposition amount by prohibiting rich spike where the oxygen concentration of the exhaust gas is controlled to a value corresponding to a rich air-fuel ratio in order to regenerate the NOx trap catalyst (13) (S301, S302, S306), and prevents the particulate matter deposition amount of the diesel particulate filter (14) from reaching a limit.
