Electrocontrolled high-pressure common rail experimental rakc

The invention is an electrically-controlled high-pressure co-path test table frame, feeding fuel oil through low-pressure pump and high-pressure pump into fuel oil injector by co-path for high pressure injection, using flowmeter, temperature sensor, pressure sensor, speed sensor installed on the high-pressure pump, fuel oil injection quantity detecting unit to collect data, analyzing and processing the data by a MCU-based control center, and sending control signal to control the co-path test table frame, and the working parameters of the system can displayed by pressure meter, flowmeter and thermometer and can also be displayed, analyzed and stored by PC terminals and the characteristic curves can be printed by printer.
