| Performance and emission control of propulsion sources are among the leading activities in transportation. In response to the growing demand for rapid diagnostic equipment, an innovative test stand dedicated to gas in- jectors has been proposed. It was based on the Szpica-Warakomski test method, which is an alternative to the Gauss characteristic area method. The essence of the new method was to determine, on the basis of the results of flow tests under specific conditions, a trend line with its parameters. Preliminary tests carried out on a prototype test stand confirmed the correctness of the design assumptions and inference method. They made it possible to refine the test conditions affecting the final evaluation. The fundamental tests carried out confirmed the sensi- tivity of the test stand to varying operating conditions. The ranges of divergence (tolerance) of the directional coefficient, the intercept point and the coefficient of determination, determined as a result of the tests of brand- new injectors, allowed the identification of deficiencies in the groups of in-operation and remanufactured in- jectors. The test stand also demonstrated its sensitivity to artificially simulated injector faults, such as decreasing and increasing plunger stroke and outlet nozzle diameter. Tests of an additional injection rail of a brand-new injector did not show exceedances of the accepted tolerance ranges of the trend line parameters, indicating a possible reduction. This achieved the possibility of rapid diagnostics of the operational state of gas injectors, which was not possible with previously available methods. |
