Abstract
In a timing control device of a fuel injection pump which is so arranged that the fuel injection timing is adjusted in accordance with the duty ratio of a driving pulse signal applied to a timing valve, the frequency of the driving pulse signal is controlled in response to data showing the rotational speed of the fuel injection pump in such a way that the resonating phenomenon does not occur whereby the timer can be actuated smoothly without resonation of the timer.
