ABSTRACT:
A detecting device for fuel injecting interval is provided, more particularly, to a portable and digital detecting device for detecting the fuel injecting interval of the injector of engine. The detecting device comprises a level transformer, a signal delay filter, a digital signal processor, and a display. The input of the level transformer 2 is electrical connected to the output load terminal of the controller 1 of the injector of engine in a way of inverse measure. The high frequency noise in the target waveform is filtered by the signal delay filter. The delay time within the detecting device is calculated by the digital signal processor and is subtracted. The resulted and exact fuel injecting interval is illustrated in the display. The detecting device features a compact configuration, easy to maintain and low service cost. Most important, the detecting device features a lower measuring error level.
