Abstract
A fuel supply control system for an internal combustion engine has an exhaust gas-purifying device arranged in the exhaust system of the engine. When a predetermined high load condition of the engine is detected, an amount of fuel supplied to the engine is increased. Temperature values indicative of the temperature of the exhaust gas-purifying device are stored and a stored temperature value is read out according to operating conditions of the engine. A correction coefficient for correcting the read-out temperature value is determined, and the temperature of the exhaust gas-purifying device is estimated based on the read-out temperature value and the determined correction coefficient. When the predetermined high load condition is detected and at the same time the estimated temperature is higher than a predetermined temperature value, the amount of fuel supplied to the engine is actually increased.
