摘要： An object of the present invention is to provide a technology that enables detection of a fault of a PM trapper with improved accuracy. In the present invention, a pressure sensor 20 that measures a differential pressure across a PM trapper 11 is provided, and a fault of a PM trapper is determined based on an amount of change in the differential pressure across the PM trapper 11 between two different operation states of an internal combustion engine 1 in which the ambient temperature around the pressure sensor 20 falls within a specific temperature range. Since variations in the offset error of the differential pressure sensor 20 caused by changes in the ambient temperature around the differential pressure sensor 20 is made small, the amount of change in the differential pressure across the PM trapper 11 can be measured more accurately, and a fault of the PM trapper 11 can be detected with improved accuracy.
摘要翻译：本发明的目的是提供一种能够以更高精度检测PM捕集器的故障的技术。在本发明中，提供了测量PM捕集器11两端的压差的压力传感器20，根据在两个不同操作之间的PM捕集器11的差压的变化量来确定PM捕集器的故障内燃机1的状态，其中压力传感器20周围的环境温度落在特定温度范围内。由于差压传感器20周围的环境温度的变化引起的差压传感器20的偏移误差的偏差变小，所以可以更精确地测定PM捕集器11的差压的变化量，可以提高精度来检测PM捕集器11的故障。

摘要： A catalyst monitoring system diagnoses deterioration of an NOX catalyst (18) which is arranged in an exhaust passage (12) of an internal combustion engine (10). An NOX sensor (25) is arranged downstream of the NOX catalyst (18). An output integrated value of the NOX sensor (25) is calculated by integrating an output from the NOX sensor (25) during at least a period near the end of air-fuel ratio control. Deterioration of the NOX catalyst (18) is diagnosed based on the output integrated value of the NOX sensor (25).

摘要： In a compression ignition internal combustion engine provided with an NOx storage-reduction catalyst on an exhaust system, when the air fuel ratio of the exhaust gas being in a lean state is controlled to a rich state, a response time (ResS) from a time point an air fuel ratio sensor detects a first air fuel ratio (AF1), which is leaner than a stoichiometric air fuel ratio (AFS), to a time point the air fuel ratio sensor detects a second air fuel ratio (AF2), which is equal to or leaner than the stoichiometric air fuel ratio (AFS) and richer than the first air fuel ratio (AF1). When the response time (ResS) exceeds a stoichiometric air fuel ratio shift reference time (StdS), a determination is made that the air fuel ratio sensor is degraded.

摘要： A hydraulic operation controlling unit where the engine can be driven stably at a target output torque point and reduction in the work speed can be prevented at the time of light load, includes an engine control unit controlling the output of an engine, so that the output properties of the engine become equi-horsepower properties or approximately equi-horsepower properties in a predetermined engine speed range (N2 to N6) that includes engine speed N3, which corresponds to a matching point M3. A controlling unit increases or reduces the absorbing torque of a hydraulic pump in response to an increase or decrease in the engine speed, and thus, controls the absorbing torque of the hydraulic pump so as to make the output torque T3 of the engine, which corresponds to matching point M3, and the absorbing torque of the hydraulic pump coincide with each other.
