    摘要: PROBLEM TO BE SOLVED: To stop the application of a load according to a working situation, to make work smooth, and to prevent the deterioration of fuel economy and the generation of white smoke by interrupting filter regeneration when an exhaust temperature cannot be maintained high at the stop of the application of the load during automatic regeneration control of a particulate filter.SOLUTION: When filter regeneration is started by the determination of the accumulation of particulates, a load requirement to a working unit is outputted to a unit control device from an engine control device at an idling or light-load operation, when the application of the load is impossible, or when a load application cancel switch is turned on, and furthermore, when the exhaust temperature cannot be maintained without being applied with the load, a regeneration interruption signal is outputted to the engine control device from the unit control device (step S7), the reception processing of the regeneration interruption signal is performed by the engine control device (step S8), and fuel addition and automatic regeneration control are interrupted (step S10) without forcibly applying the load to a hydraulic unit (step S9).

    摘要: PROBLEM TO BE SOLVED: To provide a heat-retaining/cooling control apparatus for a PM filter device, capable of controlling the temperature of an outer peripheral part of a PM filter device during combustion in the filter of the PM filter device, performing efficient combustion in the PM filter device, and preventing the effect of thermal damage to a peripheral part of the PM filter device by effectively utilizing a travelling wind. SOLUTION: An engine room and a cooling passage are constituted in parallel in the fore-and-aft direction of an operation machine and demarcated by a partition wall. An aftercooler, a cooling fan and the PM filter device are arranged in the cooling passage so that the outer peripheral part of the PM filter device is cooled through the heat waste wind from the cooling fan. When the exhaust temperature of exhaust gas is lower than a target temperature on burning a captured PM in the PM filter device, an amount of air from the cooling fan is controlled to be smaller so that the exhaust gas temperature increases. When, in contrast, the exhaust temperature of the exhaust gas is higher than the target temperature, the amount of air from the cooling fan is controlled to be larger so that a cooling effect on the outer peripheral part of the PM filter device increases.

    摘要翻译: 解决问题的方案为了提供一种用于PM过滤装置的保温/冷却控制装置,其能够在PM过滤装置的过滤器中燃烧期间控制PM过滤装置的外围部分的温度, 在PM过滤器装置中进行有效的燃烧,并且通过有效利用行驶风来防止对PM过滤装置的周边部分的热损伤的影响。 解决方案:发动机室和冷却通道在操作机器的前后方向上平行构成并由分隔壁划定。 后冷器,冷却风扇和PM过滤器装置布置在冷却通道中,使得PM过滤装置的外周部分通过来自冷却风扇的热浪而被冷却。 当在PM过滤装置中燃烧捕获的PM时废气的排气温度低于目标温度时,来自冷却风扇的空气量被控制得较小,使得废气温度升高。 相比之下,排气的排气温度高于目标温度时,来自冷却风扇的空气量被控制得较大,从而对PM过滤装置的外周部分的冷却效果增加。 版权所有(C)2010,JPO&INPIT
