Abstract
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.
Claims5
A method for an engine, comprising:
- at lower engine load,
- storing cooled boost air in an intake passage while simultaneously flowing ambient air into an intake manifold of the engine via a duct;
- and then
- responsive to an inferred temperature of the stored cooled boost air exceeding a threshold temperature, decreasing an amount of the ambient air flowed into the intake manifold of the engine and flowing the stored cooled boost air to the intake manifold.
