VIBRATION TESTER OF A HIGH PRESSURE PUMP FOR A GDI SYSTEM, CAPABLE OF IMPLEMENTING A SIMILAR SITUATION TO A VEHICLE MOUNTING STATE IN A HIGH PRESSURE FUEL PUMP FOR APPLYING VIBRATION

摘要

PURPOSE: A vibration tester of a high pressure pump for a GDI system is provided to perform a vibration test with respect to a high pressure fuel pump in advance by implementing a similar situation to the actual mounted state of the high pressure fuel pump to a vehicle and applying vibration at the same time.;CONSTITUTION: A vibration tester of a high pressure pump for a GDI system comprises a vibration test target module(112), a peripheral device, and a control device(130). The vibration test target module is a test target for a vibration test and comprises a high pressure pump for a GDI(Gasoline Direct Injection system) system and a vibration sensor for sensing vibration generation from the high pressure pump. The high pressure pump is fixed on a jig for corresponding to the engine head of a vehicle. The peripheral device operates the vibration test target module in the same environment as an actual driving environment by providing a driving force and fuel to the module through a plurality of lines. The control device is electrically connected with the module and peripheral device for controlling the environment of the vibration test.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Complex vibration tester; (112A) Pump; (112B) Cam driving unit(CAM box); (114) Hydraulic motor; (120) Hydraulic oil tank and oil cooler, Hydraulic pump; (130) Low-pressure pump and pressure control valve, Fuel tank and temperature control device; (140) Test rail; (150) Engine oil tank, Oil pump; (160) PC or control device
