PURPOSE: A method for compensating air-fuel ratio according to suction temperature of a car is provided to reduce exhaust gas and raise driving power by compensating air-fuel ratio according to suction temperature of the car. CONSTITUTION: A method for compensating air-fuel ratio according to suction temperature of the car includes the steps of inputting various signals for controlling an injection amount of a fuel injector to an ECU(Electronic Control Unit), determining the current driving area of the car through program built in the ECU and determining air-fuel ratio, and transmitting fuel injection signal to the fuel injector based on the determined air-fuel ratio if the current driving area is a full load area, compensating air-fuel ratio by suction temperature compensating weight(8) if the current driving area is an idle area or a partial load area and transmitting optimum fuel injection signal to the fuel injector.
