Abstract: A method for controlling a plurality of fans associated with a cooling package is provided. The method includes providing a first airflow through a first heat exchanger using a first fan. The method includes regulating a speed of the first fan. The method also includes providing a second airflow through a second heat exchanger using a second fan. The second heat exchanger is spaced apart from the first heat exchanger. The method further includes regulating a speed of the second fan. The regulation of the speed of the second fan is configured to control a recirculation of at least a portion of the first airflow through the second fan.

Abstract: A fuel injector includes an injector body forming an actuator portion. An actuator bore is formed in the actuator portion and is at least partially defined by an inner surface and by an end surface. An actuator disposed in the actuator bore and has an outer surface such that a flow channel can be defined between the inner surface of the actuator bore and the outer surface of the actuator. A cooling flow passage is formed in the injector body, in fluid communication with the actuator bore, and is adapted to supply cooling fluid to the actuator bore. A drain passage is formed in the injector body, in fluid communication with the actuator bore. An internal cooling fluid flow path extends from the cooling flow passage, through the flow channel, and from the flow channel through the drain passage.
