1Testing the pressure of pumping cavity of electric detection pump
2. Testing the piston stroke of the timing advance unit

EDC System Electronic Testing Device VP37 Testing Tool Traditionally mechanical VE Pump adopts mechanical speed governor in fuel control,with Centrifugal fly piece as Speed sensing elements and controls fuel return Slide set of travel by a series of Spring leverage structure. Though this kind of structure can fit with a wide range operating mode and the response speed can reach the basic requirement, traditional mechanical pump has many disadvantages: Complicated mechanical structure, large engine body and big workload of fitting and debugging. Low control accuracy The response of fuel adjustment and speed is bad Fail to operate closed loop control
