摘要： A motor vehicle cylinder head is provided with a single flat planar surface in which are formed spaced apart integral inlet and outlet ports used for connecting respective coolant supply and returns to a coolant jacket defined within the cylinder head. The use of a common planar surface for the location of the inlet and outlet ports provides a more reliable sealing of the cylinder head to the respective coolant supply and returns.

摘要： An internal combustion engine includes a cylinder block defining a cylinder and a cylinder head mounted to the block. The cylinder head supplies air and fuel to the cylinder for combustion therein. The engine also includes an exhaust manifold operatively connected to the cylinder head and having first and second outlets configured to exhaust post-combustion gasses from the cylinder. The engine also includes a turbocharging system including a low-flow turbocharger driven by the post-combustion gasses from the first outlet to pressurize the airflow and a high-flow turbocharger driven by the post-combustion gasses from the second outlet. The turbocharging system also includes a flow control device for selectively directing the post-combustion gasses to the low-flow and high-flow turbochargers. The turbocharging system additionally includes a motor-generator to selectively assist the post-combustion gasses in driving either the low-flow or the high-flow turbocharger and generate electric current when driven via the subject turbocharger.

摘要： Methods and systems are provided for thermally insulating an integrated exhaust manifold for a cylinder head of an applied-ignition, liquid-cooled internal combustion engine. In one example, a method may include regional insulation at a collection point where individual exhaust lines and/or partial exhaust lines merge to form an overall exhaust line within the cylinder head. The regional insulation may be formed integrally with a seal and coupled to an outlet flange of the cylinder head and may include a series of tongue-like projections that extend from the cylinder head outlet flange toward the cylinder exhaust lines.

摘要： An assembly includes a cylinder head with an integrated exhaust manifold that has four exhaust flow passages directing cylinder exhaust from inlets arranged to correspond with exhaust from the four cylinders, respectively, and has only three outlets. The assembly includes a twin scroll turbocharger having a housing with a first scroll passage, a second scroll passage, and only three inlets. Two of the exhaust flow passages join in the cylinder head to direct exhaust flow into only one of the inlets of the housing and through the first scroll passage. Exhaust flow through the other two of the exhaust flow passages flows separately into the other two inlets in the housing and joins in the housing to flow through the second scroll passage.

摘要： A cooling system for an internal combustion engine is disclosed. The cooling system includes a radiator for exchanging heat between a coolant and ambient air, and a coolant pump for circulating the coolant. The coolant system further includes a first set of fluid connection branches between the coolant pump and the engine block, the cylinder head and the exhaust manifold and a second set of fluid connection branches between the engine block, cylinder head and exhaust manifold and the radiator and/or the coolant pump. A first controlled valve intercepts the coolant towards the radiator so that the coolant is recirculated towards the coolant pump. A second controlled valve intercepts the coolant from the cylinder block. A third controlled valve intercepts the coolant from the integrated exhaust manifold.
