Novel high-pressure common rail fuel injector characteristic measurement and analysis system

The invention relates to the technical field of fuel injector performance testing, and discloses a novel high-pressure common rail fuel injector characteristic measurement and analysis system which comprises an oil supply system, an oil return system, an oil injection system, a test board, a control system, a measurement system, an analysis system and a display system. The oil supply system comprises an oil supply pipeline, an oil pump and an oil inlet metering module, the oil pump and the oil inlet metering module are installed on the oil supply pipeline, and the oil return system comprises an oil return pipeline and an oil return quantity metering module installed on the oil return pipeline. The oil supply system, the oil return system and the oil injection system are used for carrying out oil injection measurement simulation on a to-be-detected product high-pressure common rail oil injector; oil injection data of the high-pressure common-rail oil injector of the product to be detected under different worki
