PRESSURIZED AIR INDUCTION SYSTEM

Methods are provided for engines. In one example method, at higher engine load, cool compressed air is drawn into an engine via an air intake passage, and at lower engine load, ambient air is drawn into the engine via a duct while retaining cooled compressed air in the air intake passage. The compressed air may be released from the air intake passage based on heat transferred to the compressed air during the lower engine load, in at least one example.
