초록

In preferred embodiments, to, e.g., eliminate condensation build-up in the intake manifold and power cylinders, a charge-air cooler (CAC) and/or EGR cooler "bypass" system is provided that can, e.g., control the intake manifold temperature (IMT) above the dew-point temperature of the boosted air. Preferably, a two-port, single valve-body type valve is provided that proportionally controls the amount of charge-air that is "bypassed" (e.g., not cooled), while simultaneously diverting the charge-air cooler return, preferably, inversely proportionally.

청구항

What is claimed is: 1. A charge air cooler bypass system, comprising: a turbocharger that compresses air before it enters a charge air cooler; a charge air cooler that reduces the temperature of the air from the turbocharger before it enters an engine intake; and a bypass system that mixes higher temperature bypassed air with air from the charge air cooler to create a mixed boost-air temperature that is just above the dew-point temperature so as to inhibit condensation and the formation of acids; wherein the bypass system includes: a bypass valve that a...
