APPARATUS FOR DETECTING LEAKAGE OF FLUID IN AUTOMOBILE FUEL INJECTORS

摘要

Leakage of fluid in an automobile fuel injector (2) is detected by connecting the injector (2) on one side to a device for feeding a test fluid under pressure and on the other to a chamber (15) containing a contrast fluid different to the test fluid, supplying light radiation through the containment chamber (15), and measuring the intensity of the light radiation when it leaves said containment chamber (15).
