Electronic fuel injector tester

摘要

An electronic fuel injector tester which permits fuel injectors to be tested when a car is at idle is disclosed. The fuel injector tester is in the form of a probe and detects the impact or vibration which occurs when the pintle within a fuel injector opens by using a piezoelectric transducer provided in the pistol-type handle of the tester. A light emitting diode provided in the pistol-type handle flashes each time the pintle within the fuel injector opens and the piezoelectric transducer emits an audible sound each time the pintle within the fuel injector opens. The fuel injector tester remains in the "sleep" mode when not in use and is activated by tapping the tester on a hard surface. When testing has been completed, the fuel injector tester automatically goes back into the "sleep" mode.
