Abstract
A system for controlling fuel injection for an internal combustion engine has a fuel injector provided for injecting fuel directly in a cylinder, a cylinder pressure detector for detecting pressure in the cylinder at fuel injection, a calculator for producing a correcting coefficient in accordance with a difference between the cylinder pressure and fuel pressure, and a correcting means by multiplying the correcting coefficient to a fuel injection time, thereby changing a fuel injection duration in accordance with a change of the fuel injection timing.
