Computer thermal regulation (CTR) systems and methods for thermal energy (TE) regulation of vehicle computers designed to operate within a target temperature range (TTR). A vehicle HVAC system includes a computer heat exchanger in the computer including a phase change material (PCM) with a phase change temperature (PCT). When the computer is below a TTR lower limit, the CTR system causes the HVAC system to run a heating cycle, heating the PCM to and above the PCT. The PCM releases stored TE to the computer. When the CTR system is above a TTR upper limit, the CTR system causes the HVAC system to run a cooling cycle, cooling the PCM to and below the TTR. The PCM then absorbs heat from the computer. TE storage and release processes during phase changes enable the PCM to operate as a buffer between the HVAC system and the computer to allow finer control over the computer temperature with an otherwise over-powered HVAC system for the vehicle.

Exhaust systems are described. In examples, an exhaust flow path couples exhaust ports with one or more turbochargers of an engine. The exhaust flow path may have a portion flowing through a cylinder head (e.g., couplable to the exhaust ports) and a portion flowing through an exhaust manifold (couplable to the cylinder head and the turbocharger(s)). The flow paths may be shaped to reduce the sharpness of turns between the exhaust ports and the turbocharger(s). For example, curves along the flow path may be less than 90 degrees or have a minimum curve radius, which may vary along the flow path. Additionally, at least two, independent flow paths may exist between the exhaust ports and the turbocharger(s). The cross-sectional shape of any part of the flow path may be elliptical, including at inlets and outlets.
