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 method of controlling an inlet manifold air temperature to inhibit condensation and the creation of corrosive acids or chemicals, comprising: a) providing a bypass valve that allows exhaust gas to bypass at least one cooler; b) operating said bypass valve to inhibit condensation buildup in an intake manifold or power cylinder; and c) maintaining an intake manifold temperature substantially within a predetermined range just above the dew point temperature, wherein said bypass valve comprises a first input port and a second input ...
