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： A diesel engine oil dilution managing device is configured to act as an oil dilution detecting device to determine if a premature combustion occurred before fuel injection by an injector based on an engine parameter that correlates with an occurrence of the premature combustion, such as an amount of time required for the crankshaft to rotate per unit crank angle or a rotational speed change rate of the crankshaft. Moreover, the diesel engine oil dilution managing device can have an engine output control section that is configured to suppress the production of output power by the engine when it is determined that the premature combustion occurred before the fuel injection by, for example, driving a throttle valve in a close direction.
