Abstract: DOUBLE DAMPER ASSEMBLY FOR REDUCING THE VIBRATIONS IN INJECTORS OF AN INTERNAL COMBUSTION ENGINE According to the aspect of the present invention, a double damper assembly is provided for reducing the vibrations in engine assembly components. The double damper assembly has a high- pressure pipe (5), a plurality of injectors (7), an injector wiring harness (8), a horizontal bracket (1) and a plurality of double dampers (6). The plurality of double dampers (6) comprises a first damper (6.1), and a second damper (6.2). During the running operation/condition of the vehicle, the high-pressure pipe (5) connected to the plurality of the injectors (7) receives high vibration from the common rail injection system (10). The higher vibration on the high-pressure pipe (5) will be transferred to the plurality of injectors (7) and the injector connectors (13). To absorb the higher vibration generated in the assembly, the plurality of double dampers (6) is mounted on the high-pressure pipe (5) according to the embodiment of the invention.
