Engine cylinder head with integrated exhaust manifold and temperature sensor

A cylinder head comprising:

• a casting defining a plurality of exhaust runners that collectively form an integrated exhaust manifold disposed within the cylinder head, wherein the casting protrudes into one of the exhaust runners to form a dimple raised from a sidewall of the one of the exhaust runners;
• and
• a sensor bore defined by the casting and extending towards the dimple such that a bottom of the sensor bore is adjacent to the dimple.

A cylinder head comprising:

• a casting defining a plurality of exhaust runners that collectively form an integrated exhaust manifold disposed within the cylinder head, wherein one of the exhaust runners includes a raised dimple that forms an artificial hot spot of the casting, wherein, during operation, a temperature of the raised dimple is substantially equal to a temperature of a natural hot spot of the cylinder head;
• and
• a sensor bore defined by the casting and extending towards the dimple such that a bottom of the sensor bore is adjacent to the dimple.
