摘要: An engine cooling system includes a two-pass radiator, a jacket water pump pumping coolant from the radiator to the engine, and an aftercooler for cooling engine charge air from a turbocharger. An aftercooler pump pumps coolant from the radiator to the aftercooler. An orifice can be disposed in the aftercooler discharge line to limit flow therethrough, and an orifice bypass line with thermostatic control valve can be provided to selectively bypass the orifice. A shunt tank is connected to the suction of the jacket water pump to establish a static pressure head thereon, to ensure that the jacket water pump has sufficient suction pressure despite relatively high coolant head loss through the two-pass radiator.
