摘要

A fuel leak test system for a fuel injection system of a diesel engine is provided which includes a cranking device, a mixer, an ultraviolet ray lamp, an ID system, and a PLC. The cranking device cranks a diesel engine in an engine assembly line. The mixer mixes fuel with fluorescent material and supplies a mixture of the fuel and the fluorescent material to the diesel engine. The ultraviolet ray lamp irradiates an ultraviolet ray around the fuel injection system of the diesej engine. The ID system has results of a fuel leak test that is performed input thereto based on a change of a color around the fuel injection system. The PLC receives the data on the fuel leak test from the ID system and controls operations of the fuel injection system and operations of devices of the engine assembly line.
