Note:
there is a rectangular concave on waveform, the width of the rectangle is the
actual fuel injection pulse width, after the engine entering the closed-loop control,
fuel injection pulse width is generally 1.5ms-2.9ms. If bigger than this value, there
are clogging or excessive intake and other issues of nozzle.
