摘要:
An internal combustion engine in which an SOx trapping catalyst (12) and particulate filter (13) are arranged in a engine exhaust passage and in which a recirculation exhaust gas takeout port (17) is formed in the engine exhaust passage downstream of the particulate filter (13). Inside the engine exhaust passage downstream of the recirculation exhaust gas takeout port (17), an NOx storing catalyst (15) and a reducing agent feed valve (21) are arranged. When NOx should be released from the NOx storing catalyst (15), reducing agent is fed into the exhaust passage from the reducing agent feed valve (21).
摘要:
HC feed control for feeding HC into exhaust gas upstream of an SOx trap 11 when a predetermined condition stands is executed. When an SOx trap amount is smaller than a predetermined amount, as HC feed control, first HC feed control feeding HC into the exhaust gas upstream of the SOx trap by a predetermined pattern is executed. When the SOx trap amount is larger than a predetermined amount, as HC feed control, second HC feed control feeding HC into the exhaust gas upstream of the SOx trap by a pattern different from the predetermined pattern, which pattern keeping the temperature of the SOx trap from locally becoming higher than the predetermined temperature or suppressing the formation of a region in the exhaust gas flowing into the SOx trap where the air-fuel ratio becomes locally rich, is executed.

To provide a particulate matter purifying device which is capable of providing excessive deposition of particulate matter. In the particulate matter purifying device, a catalyst element 11 is carried on a porous filter substrate 10 through which an exhaust gas passes. The particulate matter purifying device traps particulate matter contained in the exhaust gas, and oxidizing the trapped particulate matter to remove. This particulate matter purifying device is characterized in that active oxygen producing fine particles 12 are carried on a surface of the filter substrate 10 between the catalyst elements 11. Therefore, the particulate matter is partially damaged by the active oxygen produced by the active oxygen producing fine particles 12. Consequently, oxidization of the particulate matter is promoted so that deposition of the particulate matter is prevented or minimized.

An object of the invention is to recover the capability of an exhaust gas purification apparatus provided in an exhaust passage of an internal combustion engine with improved reliability. According to the invention there are provided recovery control execution unit for executing a recovery control in which the temperature of the exhaust gas purification apparatus is raised by supply of reducing agent to a precatalyst to thereby recover the capability of the exhaust gas purification apparatus and prohibition range setting unit for setting a recovery control prohibition range that is an operation range of the internal combustion engine in which execution of the recovery control by the recovery control execution unit is prohibited. The higher the degree of deterioration of the precatalyst is, the higher the maximum values of the engine torque and the engine revolution number in the recovery control prohibition range are set to be.

摘要:
An information processing apparatus and method for reducing an unnecessary waiting time in a depacketizing process and enabling processing to be easily performed at high speeds applicable to, for example, an encoding apparatus. An analysis unit compares input image data with image data of one previous picture read out from a storage unit. On the basis of the analysis result, a concealment header generation unit generates a concealment header that is referred to by a receiving apparatus at the time of an error concealment process. On the basis of the concealment header, a loss analysis unit performs error concealment for the occurrence of a transmission error by suitably using encoded data stored in a storage unit.
摘要:
A suspension system for a traveling vehicle body is disclosed. The system includes a suspension reference position varying mechanism (18) for varying a reference position of a suspension stroke of the suspension mechanism (100), and a controller (35) configured to calculate an intermediate value from a maximal value corresponding to the maximal position of the suspension stroke and a minimal value corresponding to the minimal position of the suspension stroke, and to control the suspension reference position varying mechanism such that, when the calculated intermediate values deviates from a set target range, the intermediate value is displaced toward the target range. The controller (35) increases a control execution frequency for the suspension reference position varying mechanism (18) when the traveling speed of the vehicle body is low, and reduces the control execution frequency for the suspension reference position varying mechanism (18) when the traveling speed of the vehicle body is high.

Methods and apparatus provide for: selectively supplying a first source of power to a plurality of circuit blocks of a system using a plurality of gate circuits responsive to respective control signals provided by at least one control circuit; and providing a second source of power to operate the control circuit before the first source of power is available to the gate circuits such that the control signals are valid before such availability.
摘要:
The hydraulic suspension system comprises a suspension mechanism (100) for a traveling vehicle body, a suspension reference position variation mechanism (18) for varying a reference position of a suspension stroke of the suspension mechanism, and a stopped state detector (58) for detecting a state in which operation of the suspension mechanism (100) has stopped. The control management unit (60) controls the suspension reference position variation mechanism (18) so that when operation of the suspension mechanism (100) is detected by the stopped state detector (58) to be in a stopped state, the operation of the suspension mechanism (100) moves toward a target range, in preference to control based on a suspension stroke position obtained from a suspension stroke position sensor (37).
