摘要： A battery pack assembly includes a cell stack having a plurality of battery cells distributed along an axis and a plurality of thermal energy transfer assemblies distributed along the axis. Each thermal energy transfer assembly is disposed between axially adjacent battery cells within the plurality of battery cells. Each thermal energy transfer assembly includes a first sheet and a second sheet that sandwich an insulation layer. The battery pack assembly further includes a coolant plate assembly and a base sheet sandwiched between the coolant plate assembly and the cell stack. The base sheet is configured to communicate thermal energy from the first sheet and the second sheet to the coolant plate assembly.

摘要： Methods and systems are provided for injecting gaseous fuel during an engine start. In one example, a method comprises generating gaseous fuel via a fuel gasification device and injecting the gaseous fuel via a fuel injector. The fuel injector is configured to inject adjacent to an ignition device.

摘要： Methods and systems are provided for actuating an advanced cam profile switch (CPS) assembly. In one example, a system may include a first cylinder and a second cylinder of the CPS assembly that may be independently coupleable to a valve stem via two separate locking mechanisms. A first cam may be selectively engage with the first cylinder and the valve stem and a second cam may be selectively engaged with the second cylinder and the valve stem.

摘要： Systems and methods for reducing heat loss to a turbocharger during cold engine starting are described. In one example, a turbocharger bypass pipe and a turbocharger turbine pipe are oriented at forty five degrees relative to a longitudinal axis of a catalyst so that a turbocharger turbine may be completely bypassed, thereby increasing the amount of energy that may be transferred to the catalyst.

摘要： Methods are provided for reducing exhaust gas emissions during a cold-start of an engine. In one example, a method may include generating a flame front in an exhaust port of an exhaust system, heating exhaust gas flowing into an emission control device of the exhaust system and thereby expediting the approach to a light-off temperature of the emission control device, and directing the flame front back to the cylinder as part of a combustion stroke of the four-stroke engine cycle.

摘要： Methods and systems are provided for reducing hydrocarbon emissions from an engine. In one example, a method may include adjusting timing profiles of a first and a second exhaust valve to selectively allow pneumatic communication between a cylinder and exhaust ports of an exhaust manifold during an engine cold start.
