A gasoline engine control system includes a crankshaft rotation sensor configured to measure a rotation speed of a crankshaft, a coolant temperature sensor configured to measure a coolant temperature, an engine knocking sensor, a valve timing mechanism, an engine igniter, an air/fuel controller, and a controller configured to obtain a crankshaft rotation speed, a coolant temperature, and knocking information from the crankshaft rotation sensor, the coolant temperature sensor, and the engine knocking sensor, respectively, to determine a fuel class flowing in the engine and a cold start adaption factor, determine a fuel/cold start adaption factor based on the fuel class and the cold start adaption factor, and control an operation of at least one of the valve timing mechanism, the engine igniter, and the air/fuel controller according to the determined fuel/cold start adaption factor when the determined fuel/cold start adaption factor may be not a predetermined reference fuel/cold start adaption factor. |
