摘要:
An exhaust gas purification system for an internal combustion engine can quickly recover the exhaust gas purification ability of an exhaust gas purification device by increasing opportunities to release the SOx occluded in the exhaust gas purification device. In the exhaust gas purification system having the exhaust gas purification device having the property of occluding the SOx in the exhaust gas emitted from the internal combustion engine and collecting particulate matter contained in the exhaust gas, when the load of the internal combustion engine falls within a load range in which SOx poisoning recovery control can be executed, during the time when the particulate matter is oxidized and removed by collection ability regeneration control (S105), the collection ability regeneration control is interrupted and the SOx poisoning recovery control is executed (S106, S107).

A theoretical torque transmitted through a belt is calculated, and a first guaranteed torque is calculated by adding a marginal torque to the theoretical torque. In step S101, the theoretical torque is multiplied by a safety factor, calculating a second guaranteed torque. The second guaranteed torque is set to a value greater than a lower limit value. A smaller one of the first guaranteed torque and the second guaranteed torque is stored in a buffer, and a pressing force calculation reference torque is set through the buffer.

A vehicular power-transmission control system comprises a continuously variable transmission CVT, which transmits the output of an engine E to wheels, a starting clutch 5, which controls the transmission of power in the continuously variable transmission, an electrical motor generator M, which can assist the engine in rotational drive, and a hydraulic pump P, which is connected to the output shaft of the engine. When the vehicle, which has come into a halt with the engine consequently stopped in an idling elimination control, is to be restarted, the power-transmission control system controls the electrical motor generator to rotate the output shaft of the engine, to which fuel supply is not allowed, thereby to drive the pump. Thereafter, when the starting clutch receiving a hydraulic pressure from the hydraulic pump starts its engagement, the power-transmission control system starts the operation of the engine.

A system wherein raw material excavated from a plurality of pit faces on a mine are conveyed to and collected at a specific collecting location at the foot of a mountain by a plurality of vehicles and the degree of quality of collected raw material is then properly controlled at the specific collecting location is generally called a mining site control process. To practically execute such a mining control process, the degree of quality of conveyed raw material previously analyzed per each pit face and a quantity of conveyance thereof are confirmed at every time when the raw material is conveyed to the collecting location. Then, the degree of quality of raw material required to be next conveyed so as to allow the degree of quality predetermined as a target with respect to raw material to be collected is determined on the basis of the confirmed degree of quality and quantity of conveyance, and the manner of operating the respective vehicles is determined on a real time base so as to allow the thus determined degree of quality to be realized. When such a manner of operating the vehicles is to be determined, the most effective arrangement is selected for them in view of the representative state of actual operations of the vehicles and their loading capacity. All information in relation to such a mining site control process are electrically processed using a variety of sensors arranged at the respective pit faces and the collecting location, a computer installed in a control center and the like means.

A damper includes an outer cover having a front cover and a rear cover. The covers are joined to form a lubricant oil accommodation chamber for accommodating liquid. A damper device, a limiter mechanism, a first plate including a first collar portion located toward the front of the limiter mechanism, and a second plate including a second collar portion located toward the rear of the limiter mechanism are arranged in the outer cover. The limiter mechanism includes a first limiter plate, which is an input side on the torque transmission path, a second limiter plate, which is an output side on the torque transmission path, and a limiter disc spring, which presses the limiter plates.

A torsional damper includes a torque limiter and a damper. The torque limiter includes at least two friction members, allows transmission of torque, and prohibits transmission of excessive torque. The damper absorbs torsional vibration through resilient deformation of a spring. The torque limiter is a wet torque limiter in which the friction members are arranged in an oil chamber filled with lubricating oil. The damper is a dry damper in which the spring is not immersed in the lubricating oil.

A vehicular power-transmission control system transmits the rotational driving forces of an engine E and an electrical motor generator M through a continuously variable transmission CVT to wheels by controlling the speed change ratio of the continuously variable transmission CVT in correspondence to the operational condition of the vehicle. Additionally, the control system corrects the speed change ratio of the transmission in correspondence to the difference between the actual output of the electrical motor generator and the requested output of the electrical motor generator that is set correspondingly to the speed of the vehicle.
摘要:
In a power transmission, which adjusts and transmits the rotational output of an engine by the engagement control of a starting clutch 5, the rotational speed Ne and the suction negative pressure Pb of the engine are measured while the starting clutch is being actuated from a disengaged condition to an engaged condition with the engine being operated under a constant operational condition. An engagement-control value is calculated for the starting clutch when there is a change in the rotational speed and the suction negative pressure being measured, and the engagement-control value calculated is stored as an initial control value for starting an engaging action of the starting clutch. This initial control value is used for controlling the engagement of the starting clutch.

The invention provides a novel dual-membered suctional gasket which has a reliable function to fit and fix the gasket to an object to be sealed, and also provides an effective suction effect and air venting function. For that purpose, the gasket which has a function to prevent fluid from leaking when compressed, comprises an inner sealing member 1 and outer sealing member 2 arranged on a surface perpendicular to a compressing direction; and a plurality of connecting members 3 for connecting and fixing the inner sealing member 1 and the outer sealing member 2 together. Suction cup structures are formed, when a proper amount of air closed between the inner sealing member and the outer sealing member is vented from the inner sealing member, the outer sealing member or the both sealing members by compressing the dual-membered gasket.
