ABSTRACT:
A centrifugal ignition advancer device adapted to advance the ignition timing of an internal combustion engine according to the engine speed comprising two weights adapted to be displaced in accordance with the speed of revolution of a distributor shaft, and two springs differing from each other in initial tension and spring constant, one of the two weights being maintained in its initial position by one of the two springs while the other weight is maintained in its initial position by the other spring. Only one weight is displaced so that the rate of increase in the degree of advance of ignition timing in relation to a change in engine speed can be kept at a lower level at lower engine speeds and the two weights are both displaced so that the rate of increase in the degree of advance of ignition timing in relation to a change in engine speed can be maintained at a higher level at higher engine speeds.
