Fuel injection timing control apparatus of distributor injection pump for use in a diesel engine
A fuel injection apparatus is described comprising: (a) retarding means for, in a low range of engine loading, substantially retarding fuel injection timing by diminishing the advancing rate of the injection timing advancing means lower than a predetermined advancing rate for a high range of engine loading; (b) varying means for, in the low range of engine loading, continuously varying the advancing rate of the injection timing advancing means between the diminished advancing rate and a mostly advanced rate higher than the predetermined advancing rate of the injection timing advancing means; (c) pressure sensitive means for forcing the varying means to effect continuous variation of the advancing rate of the injection timing advancing means in accordance with atmospheric pressure; (d) first advancing rate varying means for, in the high range of engine loading, maintaining the advancing rate of the injection timing advancing means substantially at the predetermined advancing rate, and (e) second advancing rate varying means for, in the range of engine loading between the low and high ranges of engine loading.
