Abstract
A fuel injection timing control apparatus for a distributor type fuel injection pump which enables the advantages of a servo valve arrangement provided in a timing piston to be utilized with the servo valve being disposed on the timing piston high-pressure chamber side. The fuel injection apparatus can be applied to engines with parts on the timer low-pressure chamber side without this causing interference, because the servo valve and any control mechanism are provided on the high-pressure chamber side.
