摘要： A fuel-efficient hydraulic fluid has a lower viscosity than a standard hydraulic fluid, a pressure loss decreases, and thus, when control based on a standard model is exercised, the speeds of various actuators increase. However, the speeds need not be increased beyond the speeds of the standard model. Instead, it is preferred that fuel efficiency be improved. As a result, an engine revolution speed decreases by 50 rpm and a pump torque decreases by 5%. This reduces an engine output. Therefore, when a hydraulic fluid is changed from the standard hydraulic fluid to the fuel-efficient hydraulic fluid, the fuel efficiency can be improved while maintaining operability equivalent to that of the standard model. Hence, the fuel efficiency can be improved while maintaining the operability when an item affecting the fuel consumption is replaced. In addition, the settings can be changed with ease by a service technician.
摘要翻译：节能型液压油的粘度低于标准液压油，压力损失降低，因此，当进行基于标准模型的控制时，各种致动器的速度增加。然而，速度不能超过标准型号的速度。相反，优选地提高燃料效率。因此，发动机转速降低50rpm，泵转矩降低5％。这降低了发动机输出。因此，当将液压油从标准液压油改变为节油型液压油时，可以提高燃料效率，同时保持与标准型相同的可操作性。因此，当更换影响燃料消耗的物品时，可以保持燃料效率，同时保持可操作性。此外，维修技术人员可以轻松地更改设置。

摘要： A hybrid construction machine has an electric motor for driving the swing structure, and the electric motor is prevented from becoming incapable of generating torque due to a low energy state or an overcharged state of an electricity storage device. A swing-mode selector switch 77 which is manually operated switches between a hydraulic/electric combined swing mode for driving the swing structure by driving both the electric motor and a hydraulic motor and a hydraulic solo swing mode for driving the swing structure by driving only the hydraulic motor. For a normal operation, the swing mode is initially set in the hydraulic/electric combined swing mode. For a specific operation, the operator switches the swing-mode selector switch from a hydraulic/electric combined swing position to a hydraulic solo swing position.
