Fuel control apparatus for an internal combustion engine

摘要

A fuel control apparatus for an internal combustion engine comprises an intake air quantity detecting means for detecting an intake air quantity for the engine, a crank angle detecting means for detecting a crank angle of the engine, a sampling means for sampling the intake air quantity every predetermined time, a first calculating manes for calculating the means value of the sampled values every predetermined crank angle, a switching means for changing the crank angle value in accordance with the revolution speed of the engine, and a second calculating means for calculating a fuel injection quantity on the basis of the calculated means value, and a fuel injection means for injecting fuel to the engine at the fuel injection quantity obtained by the calculation.
