Abstract
A first loop contains engine coolant passageways () and a first radiator (). A second loop contains a first EGR cooler (). A third loop contains a second EGR cooler (), a second radiator (), a charge air cooler (LP), a first valve (), and a second valve (). Valve () apportions coolant flow entering an inlet (A) to parallel flow paths, one including second radiator () and the other being a bypass around radiator (). The apportioned flows merge into confluent flow to both an inlet of charge air cooler (LP) and a first inlet (B) of valve (). Valve () has an outlet (C) communicated to an inlet of second EGR cooler (). The first condition of valve () closes a second inlet (A) to coolant flowing toward both the second inlet (A) and inlet (A) while opening inlet (B) to outlet (C). The second condition of valve () opens second inlet (A) to coolant flowing toward second inlet (A) and inlet (A) of the valve () while closing first inlet (B) of valve () to outlet (C) of valve ().
