摘要：AbstractIn this paper, the scavenging concepts and scavenging control scheme in GDI engine is introduced, and then the strong scavenging and weak scavenging control function is designed in detail. From the test results on FAW technology center GDI engine test-bench, the scavenging control method is verified effectively. And the small-displacement GDI engine torque and the power performance can be improved in the scavenging conditions.
