An engine cooling system is provided. The engine cooling system includes a cylinder head including an integrated exhaust manifold that directs exhaust gases to an exhaust outlet port and a coolant passage surrounding the exhaust manifold. The engine cooling system further includes a cluster of separated exhaust passages for directing exhaust gases to the exhaust outlet port, the cluster including a drill hole disposed within material between the exhaust passages, the drill hole fluidically coupled to the coolant passage.

Integrated exhaust cylinder head

A cooling apparatus for an integrated exhaust manifold includes: a first cooling jacket configured to surround a portion of an exhaust manifold; and a second cooling jacket configured to surround another portion of the exhaust manifold. The first cooling jacket includes a first portion sitting atop the second cooling jacket and a second portion adjacent the second cooling jacket and positioned lower than the first portion.

Cooling strategy for engine head with integrated exhaust manifold

A positive crankcase ventilation (PCV) system is provided herein. The PCV system includes an engine assembly, the engine assembly including an engine block, a cylinder head, a valve cover, and an intake manifold and a PCV passage providing fluidic communication between a crankcase of the engine assembly and a cylinder intake port of the engine assembly without hoses or conduits external to the engine assembly.

PCV system having internal routing

A cylinder head for an engine is provided. The cylinder head may include an upper cooling jacket including at least a first inlet and a first outlet and a lower cooling jacket including at least a second inlet and a second outlet. The cylinder head may further include a first set of crossover coolant passages including one or more crossover coolant passages fluidly coupled to the upper cooling jacket and the lower cooling jacket and adjacent to one or more combustion chambers.

Engine with cylinder head cooling

A cylinder head of an engine with an integrated exhaust manifold is provided. In one example, the inner exhaust runners and outer exhaust runners have different cross-sectional areas. This arrangement may be beneficial to maintain exhaust flow rates in the integrated exhaust manifold.

Integrated exhaust manifold

An intake manifold for a multicylinder internal combustion engine includes a number of inlet runners operatively connected with a mounting flange. A sealing region circumscribes only an outer periphery of the mounting flange and does not extend between adjacent ones of the intake runners. The sealing region includes a continuous groove formed in the mounting flange and a sealing composition applied to the groove.

Intake manifold for multicylinder internal combustion engine

A hydraulically operated charge air system for an internal combustion engine includes an intake manifold having a number of intake runners, and a number of rotatable airflow control devices mounted within at least a portion of the intake runners. A hydraulic motor rotatably positions the airflow control devices.

Hydraulically operated charge air system for internal combustion engine

Systems and methods for selectively activating and deactivating gas exchange valves in a variable displacement internal combustion engine include a rocker arm having a positioning device that opposes movement of a lash adjustment device while deactivated to position a coupling hole of the rocker arm within a desired coupling range to facilitate coupling of the rocker arm during subsequent activation of an associated engine cylinder.

Variable displacement engine having selectively engageable rocker arm with positioning device

A poppet valve operating system for an internal combustion engine includes poppet valves which are driven by rocker arms rotationally mounted to a rocker shaft. Each of the rocker arms is maintained in axial alignment upon the rocker shaft by a separate, resiliently biased telescoping pin housed in the rocker arm body. The rocker arm pins extend into indexing reliefs formed in the outer cylindrical surface of the rocker shaft.
