Development of Common Rail Pump Inlet Meter Valve Performance Test System
Inlet meter valve is a key component of common rail pump.The performance of inlet meter valve impacts the work efficiency of the common rail pump and the common rail fuel supply system.The pressure difference of the inlet and outlet of the inlet meter valve,the driving current of the inlet meter valve and the inlet temperature of the test circuit are regulated by the test system.The flow characteristic,the leakage when the in-let meter valve is fully closed and the response time including open delay and close delay are measured.The test system eliminates the deviation of flow which is caused by only inlet pressure control.And the whole test cycle time is improved by adopting the servo valve.The results of the test experiment indicate the test system is stable and accurate.As a result,the test system has great significance for the development and manufacturing of com-mon rail pump inlet meter valve.
