ABSTRACT:
A fuel injection timing control device for an engine comprises a control member which is mechanically connected to a fuel injection pump to control the injection timing or advance angle. The output pressure of an engine driven low pressure supply pump for the fuel injection pump is balanced against the force of a spring by means of first piston which is connected to position the control member. A second piston and spring combination is exposed to the supply pump pressure in such a manner that the second piston engages with and moves the first piston and thereby the control member to a timing advance position when the engine is being started and the engine speed and the supply pump pressure are very low in order to reduce the emission of pollutants.
