ABSTRACT:
A fuel supply control system for an internal combustion engine sets an amount of heat generated within a combustion chamber at least based on an engine load condition, and a reference temperature of an exhaust system on the basis of an engine coolant temperature or other parameter associated with the engine coolant temperature. The control system predicts a temperature in the exhaust system based on the set head amount and set reference temperature. The control system derives a correction value for correcting a fuel supply amount on the basis of the predicted temperature of the exhaust system.
