Checking the tightness of the atomizer nozzle

Checking injectors for leaks

Checking the injectors for leaks is carried out on a nozzle tester.

Install the nozzle on the device and create a pressure of 2.0 MPa below the opening pressure of the nozzle. If, within 10 seconds, fuel in the form of a falling drop does not appear on the protruding part of the atomizer around the needle, the atomizer seat is sealed. With a slightly worn atomizer, its protrusion is slightly moistened without the formation of a drop.
