Abstract
There is provided a fuel supply control system for an internal combustion engine installed on an automotive vehicle. The engine has an exhaust system, and an exhaust gas-purifying device arranged in the exhaust system. A start of the engine is detected. A combustion stability of the engine is detected. The air-fuel ratio of a mixture supplied to the engine is leaned over a predetermined time period from the start of the engine depending on the detected combustion stability.
