This disclosure relates generally to battery packs for electrified vehicles, and in particular relates to a volume filler for immersion cooled battery arrays. In some aspects, the techniques described herein relate to a battery pack, including: an enclosure assembly defining a volume; a battery array within the volume, wherein the battery array includes a plurality of battery cells; and a volume filler within the volume, wherein the volume filler is disposed on a side of the battery array.

Volume filler for immersion cooling battery array designs

Methods and systems are provided for an engine for adjusting cylinder parameter settings to optimize engine output during a transient mode. In one example, a method may include adjusting cylinder parameter settings, including a cam timing setting, a spark timing setting, and a fuel injection timing setting based on a chamber temperature in response to a rate of fuel injection acceleration being greater than a positive threshold, thus indicating the engine is in the transient mode.

Methods for transient fuel control compensation

Embodiments for heating an emission control device are provided. In one example, a method for a turbocharged engine comprises during an engine cold-start, delivering boosted air from downstream of a compressor into a wastegate duct coupled across a turbine and exothermically reacting a reductant with the boosted air upstream of an exhaust emission control device. In this way, boosted air may be used to initiate an exothermic reaction to heat the device.

Secondary air introduction system

A vehicle system operation method is provided. The method comprises, during a first operating condition, increasing back pressure in a first exhaust conduit positioned upstream of a turbine and downstream of a first emission control device and during a second operating condition, reducing back pressure in the first exhaust conduit and flowing boosted air from downstream of a compressor into a second exhaust conduit positioned upstream of a second emission control device and downstream of the turbine.

Secondary air introduction system and method for system operation

Systems and methods for controlling air flow in an engine including a turbocharger are provided. One example method includes adjusting valve operation for a turbocharged engine. The method may improve scavenging and reduce exhaust blow down interference.
