    摘要： This is a method for regenerating the NOx catalyst in a NOx purifying system provided in the exhaust passage with a direct reduction type NOx catalyst which directly decomposes the NOx during lean-condition operation and is regenerated at rich-condition operation, and the method prohibiting the rich-condition control when the temperature detected by a catalyst temperature detecting means is within the predetermined temperature range.Thus, when the exhaust gas are temporarily made rich-condition for catalyst regeneration which means recovering the NOx purifying ability of the direct reduction type NOx catalyst arranged in the exhaust passage of the engine, the NOx is prohibited from being discharged into the atmospheric air, and also the purifying ability can surely be recovered.

    摘要： Adequate controllability is ensured when feedback control is provided to both the EGR valve and the intake throttle valve, and switching shock is prevented when control is switched from one to the other. The present apparatus comprises an EGR valve, an intake throttle valve, feedback control means for providing feedback control to the EGR valve and intake throttle valve such that the actual EGR volume approximates the target EGR volume corresponding to the running condition of the engine, and limiting means for limiting the operable opening ranges of the EGR valve and intake throttle valve in accordance with the target EGR volume. During EGR control of one valve, feedback control is provided to the other valve and the target opening is constantly calculated. The actual operations are merely limited, so these operations can start from the optimal opening and the switching shock can be prevented when a switch is made to the control of the other valve.

    摘要： A particulate accumulation amount estimating system is configured to accurately estimate an amount of particulate matter accumulated in a particulate filter based on the pressure difference across the particulate filter even when ash is accumulated in the particulate filter. The particulate accumulation amount estimating system is configured to estimate a particulate accumulation amount of particulate matter accumulated in the particulate filter based on a pressure difference that was detected across the particulate filter and an effective area change of the particulate filter that was detected due to the accumulation of ash in the particulate filter. The estimate of the particulate accumulation amount based on the pressure difference across the filter will be lower as the estimate value of the ash accumulation amount becomes larger.

    摘要： In an engine (10) comprising a fuel injector (12) which performs a post injection after performing a main injection into a cylinder and an exhaust valve (15) which opens and closes to discharge an exhaust gas, a controller (70) controls the fuel injector (12) to start the post injection during a period where a gas velocity in the cylinder along a cylinder axis increases after the exhaust valve (15) opens. A duration (t) of the post injection is controlled according to a crank angle at which the post injection is to be performed such that a breakup distance (L) at the end of which the injected fuel atomizes does not become larger than a distance (S) from an injection hole (12a) to a cylinder liner (10c), thereby ensuring that the injected fuel is supplied to an exhaust passage (23) without adhering to the cylinder liner (10c).
