Estimating the term…
A cooling system (10) for a turbocharged locomotive engine (12) including a two stage intercooler (20) for conditioning the combustion air (16). A first coolant loop (32) includes a first stage intercooler (38), the engine coolant passages (22), a radiator (34), a first tank (36), an oil cooler (30), and a first pump (40). A second coolant loop (42) includes a second stage intercooler (44) a subcooler (48), a second tank (46), and a second pump (50). A fluid connection is provided between the first coolant loop (32) and the second coolant loop (42) to provide heat there between during conditions of overcooling of the second coolant loop (42). Flow control valves forming a portion of first coolant loop (32) may be embodied in a single rotor-sleeve flow control valve (130).
A locomotive engine having coolant passages formed therethrough and having a turbocharger for providing combustion air through an intercooler having coolant passages formed therethrough, the engine further having a cooling apparatus comprising:
An apparatus for controlling the temperature of combustion air entering a locomotive engine from a turbocharger, the apparatus comprising:
A method for cooling an engine and cooling combustion air being supplied to the engine by a turbo-charger, the method comprising the steps of:
