PURPOSE: A crank journal lubricant apparatus for a diesel vehicle is provided to obtain the easy starting, and to reduce the wear of a crank journal and a main bearing by recovering the increased viscosity of oil lubricant at the starting of the vehicle in winter to the initial state and supplying the oil lubricant to the crank journal. CONSTITUTION: A crank journal lubricant apparatus is composed of a tank(11) for storing oil lubricant, radiating fins(21), a heater(17), an oil valve(16), an oil lubricant supplying unit, and a control unit. An inlet and outlet of the tank(11) is connected to the oil path. A plurality of the radiating fins(21) make the oil lubricant cooler by the heat exchange with the air. The heater(17) installed at the tank(11) operates at the initial starting of an engine, and heats the oil lubricant stored in the tank(11) to a predefined temperature. The oil valve(16) selectively opens/closes the outlet of the tank for storing the oil lubricant at the initial starting or overheating of the engine. The oil lubricant supplying unit supplies the oil lubricant to the tank(11) heated by the heater(17) to the crank journal. The control unit controls the operation of the above components.
