Abstract

An air-fuel ratio control system for internal combustion engine using fuel containing alcohol corrects an amount of fuel supplied to the engine by a correction amount dependent on load on the engine when the engine is in a predetermined high load region. The concentration of alcohol in the fuel is detected, and the correction amount is decreased to a smaller value as the detected concentration of alcohol in the fuel is higher.
