PURPOSE: A vehicle engine lubricator is provided to prevent the wear of a crank journal when an engine is started by supplying oil to an oil gallery, and to extend the life span of the engine and a crank shaft. CONSTITUTION: A vehicle engine lubricator includes an oil pan for storing lubricating oil and forming the lower part of a cylinder, an oil pump(24) for pumping the lubricating oil stored in the oil pan, an oil gallery(28) for conveying the pumped lubricating oil to respective driving parts, and a lubricating oil supply unit for supplying a portion of the lubricating oil to the oil gallery when an engine is started. The lubricating oil supply unit has a vessel(31), a piston(35), an outlet valve(37), an air pipe valve(38), and an air discharge pipe(39). When the engine is started, the lubricating oil is supplied to the oil gallery. An oil film is formed between a crank journal(12) and a bearing(18). Therefore, wear due to the friction of the crank journal and the bearing is avoided.
