Abstract: A system for determining a health of bearing associated with a connecting rod is provided. The system includes an oil collector placed proximate to the connecting rod and configured to receive an oil cast off from side thrust surfaces of the connecting rod during movement of the connecting rod. The system includes a sensor associated with the oil collector and configured to generate a signal indicative of a temperature of the oil cast off from the side thrust surface of the connecting rod. The system also includes a controller communicably coupled to the sensor. The controller is configured to receive the signal indicative of the temperature of the oil cast off from the side thrust surface of the connecting rod. The controller further determines the health of the bearing as a function of the signal of temperature of oil cast off from side thrust surface of the connecting rod.

Abstract: An exhaust manifold is disclosed. The exhaust manifold includes a plurality of exhaust tubes connected to one another, such that a male connector portion of one exhaust tube is received into a female connector portion of an adjacent exhaust tube. The plurality of exhaust tubes define an exhaust passage therein. The exhaust manifold also includes an air shielding zone surrounding the plurality of exhaust tubes. The exhaust manifold further includes a cooling jacket. The cooling jacket surrounds the air shielding zone. A high temperature seal is disposed within the air shielding zone. The high temperature seal is positioned outside of an interface area of the male and female connector portions of the respective exhaust tubes. The high temperature seal is configured to separate the air shielding zone into regions. Also, the high temperature seal is configured to control fluid communication between the separated regions of the air shielding zone.
