Intake condensation removal for internal combustion engine

摘要

An engine intake condensation removal system includes a valve for bypassing flow around a charge air cooler (CAC) to a liquid separator and mixer. The separator is downstream of the CAC and the mixer is downstream of the liquid separator. The mixer controls the amount of bypass flow to heat fluid flow from the CAC to a level higher than the dew point of the fluid flowing through the engine intake. The bypass flow is placed in a heat exchange relationship with the conduit receiving the output of the CAC before mixing to raise the wall temperature sufficiently to prevent condensation.
