A battery pack venting assembly includes a battery pack vent that communicates a flow of vent byproducts from a battery pack. The battery pack vent has a coolant passage that communicates a coolant to manage thermal energy levels within the flow of vent byproducts. The coolant can be a liquid coolant. The battery pack vent can be configured to communicate the flow to impinge on areas of the battery pack vent.

Battery pack venting assembly and venting method

Systems and methods for cold starting an internal combustion engine are described. In one example, fuel is delivered in four equal amounts into a cylinder during a cycle of the cylinder. The fuel is injected so as to reduce cylinder wall wetting, raise combustion stability, and increase exhaust system heating.

Methods and system for engine cold starting

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.

Systems and methods for cam profile switch (CPS) assembly

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.

Method and systems for reducing heat loss to a turbocharger during cold engine starting

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.

Methods for reducing cold start emissions for engines

Systems and methods for operating an internal combustion engine that is included in a hybrid vehicle are described. In one example, the internal combustion engine is operated in a two stroke mode during cold starting to increase mass flow to an electrically heated catalyst so that engine emissions may be reduced.

Methods and system for starting an engine

Methods and systems are provided for to methods and systems for distributing exhaust gas to a turbine, a turbocharger bypass, and an exhaust gas recirculation (EGR) line via a valve. In one example, a method may include selectively flowing exhaust gas, via a valve coupled to an exhaust passage, to one or more of an exhaust gas recirculation (EGR) passage, an exhaust turbine, and an exhaust catalyst via a bypass passage without flowing through the exhaust turbine based on engine operating conditions.

Method and system for distribution of exhaust gas

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.

Staggered exhaust valve timing for emission control

Systems are provided for a pre-chamber. In one example, a pre-chamber comprises a passage outside of a primary combustion chamber for flowing fuel directly from a fuel injector to an interior volume of the pre-chamber.

Systems for a pre-chamber

Methods and systems are provided for an injector. In one example, the injector comprises at least two passages, wherein outlets of each of the passages are differently shaped than corresponding inlets of the passages. Further, in one or more examples, each of the outlets may be shaped and sized differently with respect to each other.

Methods and systems for a fuel injector

Methods and systems are provided for adjusting engine cranking speed, fueling, and spark initiation to increase fuel vaporization during cold-start conditions. In one example, a method may include, during engine cold-start, cranking the engine at a lower speed relative to a nominal cranking speed while injecting fuel and disabling spark for a number of engine cycles, and after the completion of the number of engine cycle increasing the cranking speed and initiating spark.

Method and system for engine cold-start

Systems and methods for restarting an engine are presented. In one example, spark timing during engine starting is adjusted in response to engine speed and a second control parameter. The second control parameter may be correlated with crankshaft or rod degradation. Spark may be advanced from minimum spark for best torque when engine speed is greater than desired and when the second control parameter does not provide an indication of engine degradation.

Methods and systems for improving engine starting

Methods and systems are provided for improving engine startability during cold-start conditions, when operating with gasoline fuels, alcohol fuels, or blended fuels. In one example, a method of engine cold-start control may include initiating fuel injection for cylinder combustion with manifold pressure lowered via intake throttle adjustments. The manifold pressure is lowered based on an optimization between cylinder charge reduction and improved fuel boiling at the lower pressure.

Engine cold-start control

Methods and systems are provided for improving combustion stability, in particular during transient operations such as tip-out to lower load conditions, when EGR is being purged. Until a desired LP-EGR rate is achieved, fuel may be delivered as a split injection with at least an intake stroke injection and a compression stroke injection. Subsequently, single fuel injection may be resumed.
