Fuel control apparatus for internal combustion engine.

摘要

A fuel injection control apparatus for internal combustion engine includes an air flow meter (24) provided in a path (22) through which air is sucked into an internal combustion engine, a fuel injector (12) for controlling the amount of fuel in response to a signal from the air flow meter to produce the mixture of sucked air and fuel, and an electrical control device (64) including a microprocessor (102) responsive to the signal from the air flow meter (24) to produce, by computation of the microprocessor (102) a signal for controlling the fuel injector (12). The microprocessor (102) computes the fuel injection amount or duration (Ti) and dead time (tD) on the basis of the signal from the air flow meter. The beginning of the fuel injection by the fuel injector is altered in accordance with the dead time (tD) which is variable with the air flow amount.
