Abstract
A jacket cooling system for an engine of a locomotive is disclosed. The jacket cooling system may comprise a jacket coolant pump driven by a crankshaft of the engine. The jacket cooling system may further comprise a coolant jacket associated with one or more components of the engine, and a delivery conduit in fluid communication with the outlet of the jacket coolant pump and configured to deliver a coolant from the jacket coolant pump to the coolant jacket. The jacket cooling system may further comprise a bypass circuit configured to divert the coolant away from the delivery conduit and the engine, and an electronically-controlled bypass valve in the bypass circuit. The bypass valve may allow at least some of the coolant to flow through the bypass circuit when a valve position of the bypass valve is at least partially open.
