The control strategy, on the basis of features and demands of cold start conditions, was developed and illustrated thoroughly. The experimental platform was built up and the program of the cold start control strategy was written based on the preliminary work of electronic control system and test bench, and the research on cold start was made. The results show that the engine starts by three cycles successfully with the optimal control parameters for each stage to control cold start process. The engine speed fluctuated around 1023r/min and the speed fluctuation rate was only 6%. The light-off time of the catalyst was 38s and HC emission was at lower lever. The control strategy can meet the general demands for GDI engine cold start.
