Abstract

A cooling system including an intake air cooling subsystem and a liquid cooling subsystem for controlling intake air temperatures in a supercharged internal combustion diesel locomotive engine. The intake air cooling subsystem includes an air-to-water aftercooler and an air-to-air aftercooler having intake air sides connected to receive intake air flow in series between a supercharger and an engine. The liquid cooling subsystem includes at least one liquid cooling loop having a pump, a radiator and a water coolant side of the air-to-water aftercooler. At least one shared fan circulates air flow to the cooling air sides of the air-to-air aftercooler and the radiator. An optional air distribution control selectively directs circulated air flow between the air-to-air aftercooler, the radiator and other optional components of the cooling system.
