Document Type and Number:
Japanese Patent JP4393264
Kind Code:
B2
Abstract:
A fuel leak test system for a fuel injection system of a diesel engine 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 under a high pressure condition. The ultraviolet ray lamp irradiates an ultraviolet ray around the fuel injection system of the diesel engine. The ID system receives results of a fuel leak test 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.
