PURPOSE: A method for controlling an engine of a car is provided to increase travelling performance and engine efficiency by controlling the engine on the basis of output torque of the engin to exactly correspond to a driver's request and a travelling state of the car. CONSTITUTION: A method for controlling an engine of the car includes the steps of detecting a depth of an acceleration pedal, rotational frequency of an engine, opening amount of a throttle and an inhaled air amount, determining target torque from a stored target torque map and the current torque from the current torque map, controlling the current torque to approach the target torque by compensating ignition time of an ignition plug of the engine, controlling the current torque to approach the target torque by adjusting opening degree of a throttle valve if the current torque does not approach the target torque through the compensation of the ignition time, and controlling the current torque to approach the target torque by adjusting air-fuel ratio if the current torque does not approach the target torque through the adjustment of the opening degree of the throttle valve.
