SYSTEM FOR TESTING PERFORMANCE OF INJECTOR AND CLEANING INJECTOR, AND METHOD FOR TESTING PERFORMANCE OF INJECTOR AND CLEANING INJECTOR

摘要

A system for testing performance of an injector and cleaning the injector according to an embodiment of the present invention comprises: a fuel supply unit having a plurality of injectors installed on a fuel distribution line connected to a fuel tank; a plurality of cleaning and visualization chambers connected to the plurality of injectors to accommodate fuel sprayed from the injectors; a fuel amount measurement unit which has a plurality of spray amount measurement chambers connected between the cleaning and visualization chambers and the fuel tank, and measures a fuel spray amount of the fuel sprayed from the injectors and supplied to the spray amount measurement chambers via the cleaning and visualization chambers; a cleaning unit connected to the cleaning and visualization chambers in a closed circulation structure to supply cleaning liquid to the cleaning and visualization chambers to clean the injectors when the cleaning liquid circulates; and a control unit which is connected to the fuel supply unit, the cleaning unit, and the fuel amount measurement unit, controls the fuel amount measurement unit to test whether the injectors are in a condition which requires cleaning, and controls the fuel supply unit and the cleaning unit to operate the fuel supply unit and the cleaning unit to clean the injectors if a condition of the injectors requires cleaning.
