Methods and systems are provided for a cylinder head with an exterior wall including a removable camshaft carrier. In one example, a cylinder head includes a camshaft carrier removably couplable to a mount surface of the cylinder head and adapted to form a portion of an exterior wall of the cylinder head while coupled to the mount surface. The camshaft carrier may include a first section removably couplable to the cylinder head and a second section removably couplable to the first section, with the first section and the second section together shaped to receive a camshaft journal.

A cylinder head for an internal combustion engine includes a casting and plug. The casting defines a first channel, a second channel, and a bore extending inward from an exterior surface of the casting. The first channel intersects a central portion of the bore. The second channel intersects an opposing end of the bore relative to the exterior surface. The plug is disposed within the bore. The plug has a distal end that engages the casting along the opposing end of the bore via a slip-fit engagement, a proximal end that engages the casting within the bore proximal to the exterior surface via a fixed engagement, and an intermediate portion that is spaced apart from the casting along the central portion of the bore. The plug defines an internal channel that establishes fluid communication between the first and second channels.

Systems for an integrated exhaust manifold cylinder head are provided. In one example, an exhaust manifold for a vehicle includes a plurality of exhaust runners coupling a plurality of cylinder exhaust gas outlet ports to an exhaust exit port, the plurality of exhaust runners forming at least a first exhaust passage and a second exhaust passage at the exhaust exit port; an upper cooling jacket positioned vertically above the first exhaust passage; a lower cooling jacket positioned vertically below the second exhaust passage; and a central cooling jacket positioned vertically below the first exhaust passage and vertically above the second passage.

An engine includes a block defining at least one cylinder and a cylinder head received on the block. The cylinder includes a casting defining an exhaust port in fluid communication with the cylinder and an integrated exhaust manifold. The integrated exhaust manifold has an exhaust runner defined by the casting and extending from the exhaust port to an outlet defined on an outer surface of the casting. The casting includes a protrusion extending into the exhaust runner such that a raised dimple is disposed on a sidewall of the exhaust runner. The casting further defines a sensor bore extending towards the protrusion such that the sensor bore and the protrusion have a common centerline. A temperature sensor is disposed in the sensor bore and has a sensing element arranged in proximity to the protrusion such that the sensing element reads a temperature of the protrusion.

Methods and systems are provided for oil flow for hydraulic lash adjusters of a vehicle engine. In one example, an engine cylinder bank includes a plurality of deactivatable hydraulic lash adjusters and a plurality of non-deactivatable hydraulic lash adjusters. A first linear oil supply passage and a second linear oil supply passage are formed within the cylinder bank and extend linearly through the cylinder bank without bends or curvature to the deactivatable and non-deactivatable hydraulic lash adjusters, with the deactivatable and non-deactivatable hydraulic lash adjusters having a same length.

Methods and systems are provided for a cam carrier insert coupled to a cylinder head of an engine. In one example, a system may comprise: a cylinder head with a cam bearing tower; a cam carrier insert positioned in the cylinder head; and a camshaft, the camshaft directly supported by the cam bearing tower and directly supported by the cam carrier insert. By mounting a first portion of the cam shaft to the cam bearing tower and a second portion of the cam shaft on the cam carrier insert, the system may operate deactivatable and non-deactivatable intake or exhaust valves of one or more engine cylinders in the engine. In this way, packaging of engine components within the cylinder head may be improved while promoting better engine performance.

Cam carrier insert

An engine, such as a variable displacement engine, has a camshaft retainer. The camshaft retainer has a cap adapted to cooperate with a carrier to support first and second overhead camshafts for rotation. The retainer cap forms a housing for a camshaft journal bearing. The retainer cap also forms a retainer land defining an open channel adapted to provide a jet of lubricating fluid from the bearing housing to externally lubricate a cam. The retainer land is adapted to mate with a sealing land of the carrier to enclose the open channel.
