ELECTRONIC CONTROLLED EXHAUST VALVE ACTUATING EQUIPMENT USING THE MECHANICAL HYDRAULIC ACTUATOR FOR THE DIESEL ENGINE

PURPOSE: An electronic-controlled ventilation valve driving device using a machinery hydraulic actuator of a diesel engine is provided to improve the stability of an electronic-controlled ventilation valve driving device by being converted into a machinery ventilation valve driving device in case of the malfunction of main components. CONSTITUTION: An electronic-controlled ventilation valve driving device using a machinery hydraulic actuator of a diesel engine comprises multiple machinery hydraulic actuators(110), an accumulator(120), multiple control valves(140), and an electronic control device(150). The multiple machinery hydraulic actuators are driven by an exhaust cam(10) to transmit hydraulic oil for the drive of an exhaust valve(30). The accumulator is connected to the machinery hydraulic actuator and axis-compresses the hydraulic oil transmitted from the machinery hydraulic actuator. The multiple control valves are driven by the solenoid to control hydraulic oil supplied to the oil chamber(31) of the exhaust valve. The electronic control device controls the opening and closing time of the exhaust valve by controlling the control valve.
