    摘要： An engine control system for a working machine measures the sulfur content of an exhaust gas since sulfur is detrimental to normal functioning of an exhaust gas aftertreatment device. Each time a key switch is turned ON to start an engine, the engine control system compares a remaining fuel amount memorized at the last stop of the engine and a remaining fuel amount detected at the current start of the engine. The engine control system performs a sulfur concentration measurement process only when the remaining fuel amount is increased. A target revolution speed Na appropriate for measuring the concentration of sulfur is set and when the temperature of the exhaust gas is within a predetermined temperature range and a target time has elapsed, the engine control system determines whether the sulfur concentration exceeds a threshold value. If the sulfur concentration exceeds the threshold value, an alarm display device is activated.

    摘要： When the actuator drive torque of a hydraulic pump is lower than a switching torque τ0, a controller closes a solenoid switching valve and makes a rotary electric machine function as a generator. With the increase in the actuator drive torque, the controller controls a pressure compensated flow control valve so that the flow rate of hydraulic fluid supplied from the hydraulic pump to a rotary hydraulic device decreases. When the actuator drive torque is higher than the switching torque, the controller opens the solenoid switching valve, makes the rotary electric machine function as an electric motor, and controls the pressure compensated flow control valve so that the hydraulic fluid discharged by the hydraulic pump is not supplied to the rotary hydraulic device. Consequently, shocks due to flow rate fluctuation are prevented when operational states of the rotary hydraulic device and the rotary electric machine are switched.

    摘要翻译： 当液压泵的致动器驱动扭矩低于开关转矩τ0时，控制器关闭电磁换向阀并使旋转电机作为发电机。 随着致动器驱动转矩的增加，控制器控制压力补偿流量控制阀，使得从液压泵供给到旋转液压装置的液压流体的流量减小。 当执行器驱动转矩高于开关转矩时，控制器打开电磁换向阀，使旋转电机作为电动机，并控制压力补偿流量控制阀，使液压泵排出的液压油为 不提供给旋转液压装置。 因此，当旋转液压装置和旋转电机的操作状态被切换时，防止由于流量波动引起的冲击。
