摘要： The exhaust gas purifier includes a fuel addition valve (71), an NOx catalytic converter (72), and a catalyst loaded PM filter (73). The catalyst temperature of catalyst loaded PM filter (73) is increased to a target temperature by adding fuel to the exhaust gas from fuel addition valve (71), whereby PM trapped on the filter (73) is purified. When the NOx catalytic converter (72) is deteriorated, the target catalyst temperature of catalyst loaded PM filter (73) is changed to a value larger than the target catalyst temperature when the NOx catalytic converter is in a normal state.

摘要： If the amount of fuel added to exhaust gas becomes excessive as a result of an abnormality of an addition agent supply unit (60), the air-fuel ratio of exhaust as decreases. If an exhaust gas air-fuel ratio obtained from a value output from an A/F sensor (4) remains equal to or smaller than a predetermined value for a predetermined period, an ECU (2) determines that an addition agent supply unit (60) is abnormal. Upon detection of an abnormality of the addition agent supply unit (60), the ECU (2) incrteases an amount of EGR gas recirculated to the intake side by an EGR unit (40), reduces an amount of fuel injection from injectors (11), and restricts an operational state of an engine body (10) to a low-speed/low-load state. Also, the ECU (2) turns a warning lamp (7) on, warns a driver of the abnormality of the addition agent supply unit (60), and makes it possible to pull a vehicle over safely.

摘要： Whether discharge of high-concentration, unburned fuel is indicated or not is determined based on air-fuel ratio AF, calculated air-fuel ratio AFc and exhaust temperature thco (S110, S112, S114). If it is determined that high-concentration, unburned fuel would be discharged ("no" in any of S110, S112, S114), amount of fuel addition per one addition is decreased in PM regeneration control (S116). Therefore, in a state where high concentration HC is to be discharged to the downstream of an exhaust purifying filter, the amount of fuel addition at one time is immediately decreased, so that discharge of high-concentration HC to the outside can be prevented, and generation of white smoke can reliably be prevented.
摘要翻译：基于空燃比AF，计算出的空燃比AFc和排气温度thco确定是否指示高浓度未燃燃料的排出（S110，S112，S114）。如果确定高浓度未燃烧燃料将被排出（S110，S112，S114中的任何一个中为“否”），PM再生控制中的每一次添加量的燃料添加量减少（S116）。因此，在将高浓度HC排出到排气净化过滤器的下游的状态下，一次燃料添加量立即减少，能够防止高浓度HC向外部排出，可以可靠地防止白烟的产生。

摘要： An electronic controller (6l) integrates a rate of progress (dK) of thermal degradation of exhaust purifying catalyst (42A, 43A) at every predetermined time period, to calculate degree of thermal degradation (K) of the exhaust purifying catalyst (42A, 43A) , when the state of thermal degradation of the exhaust purifying catalyst (42A, 43A) is to be detected. By comparing the degree of thermal degradation (K) with a defect determining value S, whether the exhaust purifying catalyst (42A, 43A) is defective because of thermal degradation or not is determined. In calculating the degree of thermal degradation (K) , the electronic controller (61) calculates the rate of progress (dK) of thermal degradation in the predetermined time period based on the integrated value of rate of progress (dK) of thermal degradation up to the last time (degree of thermal degradation K) and on the temperature (T) of exhaust purifying catalyst (42A, 43A) at that time, and adds the same to the integrated value up to the last time .

摘要： A fuel injection control apparatus has a rail pressure sensor (43) and an electronic control unit (ECU) (52). The ECU (52) converts the common rail pressure (analog signal) detected by the rail pressure sensor (43) into a digital signal by an A/D converter (53, 55), and controls the injection amount and the injection pressure based on the converted rail pressure. During the injection amount control, the ECU (52) determines an injection period based on an injection amount instruction value and the rail pressure, and causes an injector (23) to inject fuel over the injection period. During the injection pressure control, the ECU (52) controls a supply pump (27) so that the rail pressure converges to a target pressure. Furthermore, the ECU (52) performs the sampling for computing a rail pressure for the injection amount control and the sampling for computing a rail pressure for the injection pressure control at different timings.
