Abstract: A battery pack system includes first and second battery arrays of a traction battery pack and a thermal barrier assembly disposed at least partially between the first and second battery arrays. The thermal barrier assembly is configured to block thermal energy movement from the first battery array to the second battery array, and from the second battery array to the first battery array. The thermal barrier assembly includes a primary attachment portion, a first lip that interfaces with the first array, and a second lip that interfaces with the second array. The system further includes a routable component of the traction battery pack. The routable component is received within a channel of the first lip and a channel of the second lip.

Abstract: Methods and systems are provided for a compressor of a turbocharger of an engine. In one example, a compressor may include a flow passage and a resonance chamber surrounding the flow passage, with the flow passage fluidly coupled with the resonance chamber by a recirculation passage, a bleed passage, and a plurality of apertures positioned between the recirculation passage and the bleed passage. Flowing fluid from the resonance chamber, through the apertures, and into the flow passage may reduce a noise level of the compressor.

Abstract: A system for an engine comprising an engine drive system and an oil delivery system is provided. According to one embodiment, the engine drive system includes a chain that engages a plurality of drive sprockets and a chain guide that pivots about a pin. Further, the pin may include an internal oil passage that is in fluidic communication with the oil delivery system. In this way, improved oil lubrication can be provided with simplified structure and manufacturing.

Abstract: A system for an engine drive that engages a timing band with a camshaft and a crankshaft is provided. The system further includes a coupling device that couples the camshaft to another camshaft that is not engaged with the timing band. The coupling device and the camshafts are in such a configuration that the camshafts rotate in opposing directions.
