Abstract
A fuel injection apparatus for a distributor injection pump for use in a diesel engine. The apparatus has an injection timing advancing device which advances a fuel injection timing of the distributor injection pump at an advancing rate responsive to a change of engine loading. A timing control includes a variable pressure relief system for changing the amount of pressure relieved from a pump chamber of the distributor injection pump. This variable pressure relief system can change the advancing rate of the injection timing advancing device in such a way that the advancing rate becomes lower in a low range of engine loading than in a high range of engine loading. The advancing rate may be continuously increasingly varying from that determined by the low engine loading in accordance with atmospheric pressure to a mostly increased advancing rate which is higher than a predetermined advancing rate in the high range of engine loading.
