Problems solved by technology

[0003] In the actual operation of the diesel engine, in order to ensure the normal and stable operation of the injection valve, the diesel engine is required to respond within a certain period of time under the action of the servo oil of the high-pressure common rail pipe after the diesel engine drives the solenoid valve; An appropriate amount of fuel requires the valve stem to reach the designed displacement and opening time; start to inject fuel after the injection timing is reached, if the injection is not punctual, it may cause problems such as low combustion efficiency, worsened emissions, and serious after-combustion
During the operation of the diesel engine, if the untested and substandard injection valve is used, the operation of the diesel engine will be unstable, and the injection timing and injection quantity will be inaccurate, which will lead to the failure of the whole machine and shorten the service life

Abstract

The invention discloses an electrically-controlled multi-station multi-type injection valve performance detection device. The electrically-controlled multi-station multi-type injection valve performance detection device is characterized by comprising an upper computer, a lower computer, a router and an auxiliary subsystem. Relevant data of the injection valve performance are obtained by simulatingdifferent working conditions that a low-speed diesel engine drives different injection valves, performance parameters of the valves are obtained through real-time calculation, preset parameters, calculation results and real-time state parameters are compared in real time in the testing circulating process, overall multi-cycle testing is terminated or completed, and a report is output. According to the electrically-controlled multi-station multi-type injection valve performance detection device, multi-station testing can be directly conducted on multi-type low-speed diesel engine injection valve functions in a laboratory environment through a physical simulation mode without real diesel engine running, the cost is reduced, environment pollution is reduced, and the unnecessary maintenance cost brought by faults generated due to the fact that the injection valve performance is not up to the standard in the actual diesel engine running process is reduced.
