Abstract
An engine control method for cold start stabilization is provided. The method includes detecting, by a controller, a cold start based on a cold start condition of a soaking condition of an engine in response to sensing a starting of the engine. In addition, a turbo charger is operated with a control value of a vane corresponding to a first allocated bit. After the cold start, either a normal control is performed to operate the turbo charger according to an engine running condition or cold start-2 is performed to again operate the turbo charger with a control value of the vane corresponding to a second allocated bit and then performing the normal control.
