DEVICE FOR MEASURING DRIVING FORCE OF CAM SHAFT IN VIEW OF CHARACTERISTICS OF FLOW DISTRIBUTION OF ENGINE VALVE TRAIN

摘要

PURPOSE: A driving force measuring device is provided to evaluate the damage of an engine and the change of the engine performance by analyzing the friction characteristics of an engine valve train according to a flow amount distribution by measuring the driving force of a cam shaft in view of the flow and temperature of oil supplied to a cylinder head for lubrication of the engine valve train. CONSTITUTION: A driving force measuring device includes a torque meter(80) mounted on a line with an A/C motor(90) mounted with an inverter(92) and a cam shaft for driving a valve train of an engine main body(100) for controlling a rotation number of the cam shaft, an oil control part(50) mounted to a heater and a flow meter for controlling a flow and a temperature of oil supplied via the valve train, a cooling water control part(40) mounted with the heater and storing cooling water for compensating the temperature of the engine main body with a real operation condition, and a control part(70) for controlling the rotation number of the A/C motor mounted to the inverter, the flow and the temperature of the oil control part and the cooling water temperature of the cooling water control part.
