Diesel engine fuel sprayer coking analogue test device

The utility model discloses a diesel engine fuel sprayer coking analogue test device, include, pressure control unit, oil -gas pipeline, oil storage tank, sprayer assembly unit, computer control unit and electric actuator unit, the pressure control unit passes through oil, trachea line and sprayer assembly unit intercommunication through oil, trachea line intercommunication oil storage tank, oil storage tank, and computer control unit passes through the experimental parameter setting of electric actuator unit control sprayer assembly unit. The beneficial effects are that, adopt this test device evaluation light diesel oil to generate the deposit incline on the diesel engine fuel sprayer, accomplish to have differentiation nature, repeatability, reproducibility and dependence to the evaluation of commercially available light diesel oil basically, but wide application in monitoring and supervise inspection field, can be fast, the accuracy inspects product correlation index, experimentation cost is cheap. To standardizing the diesel oil service property (quality) on the fuel market, rigorously enforce the diesel vehicle and discharge, have obvious meaning, meet the standard diesel oil can not the field of circulating.
