ABSTRACT:
A fuel injection timer for internal combustion engines, wherein a shaft of a fuel injection pump is rotated relative to a drive shaft connected to the internal combustion engine as a function of the rotational speed of the engine. Oscillating bodies are disposed between first tracks connected to the drive shaft and second tracks connected with a shaft of the fuel injection pump. The first and second tracks are disposed in opposed pairs and the oscillating bodies each transmit a portion of the pump drive torque and move from an inner end position at a lower rotational speed of the engine to an outer end position at a maximum rotational speed of the engine under the influence of centrifugal forces and counteracting spring forces. A slope formed by the tracks affects the relative torque between the two shafts with the displacement curve of the injection time which corresponds to a favorable combustion cycle. Several of the track pairs have a non-uniform slope pattern over their displacement path, with a segment of the displacement path being constructed as a slight slope so as to cause self-locking between the tracks and the corresponding oscillating bodies. These segments of the individual track pairs are each associated with rotational angles of the shafts at which high torque peaks occur or at which there is a danger of oscillation for the injection timer as a result of resonances.
