Abstract: A system for optimizing engine braking power is provided. The system includes an intake manifold configured to receive air from a compressed air source. The system includes an engine brake associated with a power source. The system also includes a bleed valve configured to bleed a portion of the air from the intake manifold. The system further includes a controller in communication with the bleed valve and configured to receive a status of the engine brake. The controller is configured to activate the bleed valve to bleed a portion of the air from the intake manifold based at least in part on the engine brake being active and based at least in part on a pre-determined relationship between an air pressure in the intake manifold and one or more parameters associated with the power source.

Abstract: A multi-paneled cooling module adapted to be mounted to an engine exterior protects electronic components such as sensors and associated wiring from heat loads of the engine and/or other heat generating engine devices. The module is formed of wall and ceiling panels having a relatively high thermal conductivity, such as aluminum. The cooling module, which includes strategically situated integral coolant passages within several of its panels, is adapted to protect all enclosed electronic components, including electronic pressure sensors, an EGR valve, and all associated wiring and wiring harnesses. For example, the sensors, harnesses, and valve components associated with and proximal to an EGR venturi may be fully protected from overheating, in spite of exposure of those components to massive heat loads generated by the venturi. Finally, the cooling module may incorporate additional cooling accommodation for hydraulic oil cooling if, for example, the EGR valve is hydraulically actuated.
