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.

Abstract: A cooling system is disclosed for an internal combustion engine. The cooling system may include a first cooling circuit having a first coolant that flows through cooling channels of an engine, and a second cooling circuit having a second coolant that flows through a charge air cooling component. The cooling system may further include a drain line adapted for fluid communication with the first and second cooling circuits. A first temperature responsive valve disposed on the second cooling circuit may be included, the first temperature responsive valve configured to open to allow mixing of the first and second coolants when the temperature of the second coolant is at a preselected minimum temperature. Also included may be a second temperature responsive valve disposed on the drain line and configured to open to drain both cooling circuits when the temperature of the first and second coolants is at a preselected minimum temperature.

IPC: F02M26/29
Abstract: An EGR cooler may include an EGR cooler housing having top, bottom and side walls, inlet and outlet end walls disposed at opposite ends, and a longitudinal axis extending in a direction of exhaust gas flow from the inlet end to the outlet end. A plurality of cooling tubes extend through the EGR cooler between the top and bottom walls, and are arranged in a cooling tube array to form an exhaust gas receiving area at an upstream side of the cooling tube array proximate the inlet end wall so that exhaust gas flowing into the EGR cooler through an exhaust gas inlet opening will flow into the exhaust gas receiving area and then disperse through the cooling tube array. A pitch distance between the cooling tubes may be greater proximate the longitudinal axis than proximate the side walls to promote flow through, instead of around, the cooling tube array.

Abstract: An oil pump for an engine is disclosed. The oil pump may include a first pump mechanism configured to supply oil to a main lubrication gallery of the engine, and a second pump mechanism configured to supply oil to a piston cooling gallery of the engine. The first pump mechanism may be designed for a first type of engine and the second pump mechanism may be designed for a second type of engine. The first type of engine may have a greater quantity of cylinders than the second type of engine.
