Abstract:
1. A fuel supply control apparatus for an internal combustion engine, which serves to supply fuel in a fuel tank to an injector installed in a combustion chamber of an internal combustion engine, said apparatus comprising: a crank angle detection section for generating a crank angle signal in synchronization with the rotation of a crankshaft of said internal combustion engine; a cam angle detection section for generating a cam angle signal in synchronization with the rotation of a camshaft of said internal combustion engine; a positive displacement fuel supply section having a suction stroke and a discharge stroke synchronized with the rotation of said camshaft for supplying said fuel to said injector; and an effective stroke changing section for changing an effective stroke related to the discharge stroke of said fuel supply section; wherein said effective stroke changing section operates in synchronization with said crank angle signal and said cam angle signal so as to change said effective stroke based on said cam angle signal wherein said effective stroke changing section operates in synchronization with said crank angle signal and said cam angle signal so as to change said effective stroke based on said cam angle signal, wherein said effective stroke changing section changes said effective stroke by correcting a deviation of each pulse of said cam angle signal.
