    Engine NVH End-of-Line Test Bench (NVH Test) Engine Electrical Test Bench Spark Plug Tester Engine Rotational Torque Test Bench TDI Engine Fuel System Test Bench Transmission Reliability Test Bench Engine Performance Test Bench Diesel Engine Load Hot Test Bench HEV/EV Powertrain Performance Test Bench W-Ibeda New Energy Automobile Powertrain and Vehicle Test Center Chassis Dynamometer Oil Pump Research & Development Test Bench Fawer Commercial Vehicle Steering Engine Camshaft Profile Tester Clutch Function Tester Engine Cold Test Bench

    Engine NVH End-of-Line Test Bench (NVH Test)
    Engine NVH EOL test bench adopts professional NVH analyzer to test vibration of cylinder head, intake/discharge sides of engine without ignition of engine (cold status). Besides, Engine NVH EOL test bench monitors engine oil pressure and torque during the entire test process, and check if assembling faults and part quality faults exist or not on basis of test results.
    APPLICATION - Gasoline engine EOL test
    - Diesel engine EOL test

    - Engine is not ignited during test; no coolant and fuel is needed; no exhausted gas and liquid;
    - Adopt professional NVH analyzer from 3rd party (Reilhofer EOL vibration analyzer), which provides overall
       analysis of vibration signal at different rotation to detect possible faults of engine rotating parts
    TEST ITEM - High Speed NVH Test - Low Speed NVH Test
    - Safe Torque Monitoring - Safe Oil Pressure Monitoring
    PRODUCT BEAT - Tempo≤60s (feeding and discharging included)
