Abstract
Methods and systems are provided for a coolant system coupled to cylinders in a locomotive engine. In one example, a coolant system coupled to an individual cylinder may include a cylinder liner jacket encircling the cylinder, a cylinder head lower coolant jacket surrounding a lower surface of a cylinder head placed over the cylinder, a cylinder head upper coolant jacket surrounding an upper surface of the cylinder head, and a cylinder head exhaust port cooling jacket surrounding an exhaust port of the cylinder. Coolant may flow to each of the cooling jackets from a coolant feed gallery located in the engine crankcase, and after flowing through the engine, the coolant may return to a coolant return gallery also located in the engine crankcase.
