摘要： Provided is a heat retention/cooling control device for a PM filter device, which controls the temperature of the outer periphery of the PM filter device to ensure an efficient burning in the PM filter device and prevents the influence of heat damage on the periphery of the PM filter device by effectively using moving air. An engine room and a cooling passage which are demarcated by a partition wall are provided in parallel in the front-back direction of an work machine, and an aftercooler, a cooling fan, and a PM filter device are provided in the cooling passage. When the exhaust temperature of exhaust gas is lower than a target temperature when PM is burned, the air volume of the cooling fan is controlled so as to decrease, thereby increasing the exhaust gas temperature. When the exhaust temperature of the exhaust gas is higher than the target temperature, the air volume of the cooling fan is controlled so as to increase, thereby enhancing the effect of cooling the outer periphery of the PM filter device.

摘要： There is provided a retarder control device which is simple in constitution and can reliably apply braking. An engine rotational speed detector detects an engine rotational speed, gear step detection means detects a gear step of a transmission, an accelerator operation detector detects the operated state of an accelerator, and a retarder controller previously stores automatic braking amount determination data representing the relation between the engine rotational speed and the automatic braking amount of a retarder corresponding to each gear step of the transmission and controls the retarder according to the automatic braking amount of the retarder calculated from the automatic braking amount determination data based on the detected engine rotational speed and gear step of the transmission when the accelerator is judged to be off from the detected operated state of the accelerator.
