1. A gasoline engine control system of an engine, comprising:

  • a crankshaft rotation sensor measuring a rotation speed of a crankshaft;

    a coolant temperature sensor measuring a coolant temperature;

    an engine knocking sensor;

    a valve timing mechanism;

    an engine igniter;

    an air/fuel controller; and

    a controller obtaining the rotation speed of the crankshaft, the coolant temperature, and knocking information from the crankshaft rotation sensor, the coolant temperature sensor, and the engine knocking sensor, respectively,wherein the controller determines a fuel class flowing in the engine and a cold start adaption factor,wherein the controller determines a fuel/cold start adaption factor based on the fuel class and the cold start adaption factor, andwherein the controller controls an operation of at least one of the valve timing mechanism, the engine igniter, and the air/fuel controller according to a determined fuel/cold start adaption factor when the determined fuel/cold start adaption factor is not a predetermined reference fuel/cold start adaption factor.
