ABSTRACT "INJECTOR TESTER" A device for testing fuel injectors in situ. The device comprises a detector having a piezo-electric crystal which converts mechanical impulses caused by the fuel injector valve needle snapping back onto its seat into electrical signals. The signals are fed to electronic processing means which detects the signal amplitude and displays it on an LED bar graph display as an indication of the operating efficiency of the fuel injector. A timing system using the detector as a generator of timing signals is also disclosed.
