Question

engine
the housing of a piston engine is called the engine block or cylinder block. the engine assembly consists of 3 major components:

1. cylinder head.
2. engine block.
3. oil pan or crankcase.

water jackets, coolant passages, and oil galleries are found in the block and cylinder head. they cool the engine and supply oil to moving parts.
the cylinders are found in the block and house the pistons.
the crankshaft is attached to the block with bearing caps and bolts or a bed plate.
the camshaft and valves are located in the cylinder head in an engine with an overhead camshaft configuration.
the cylinder head seals the top of the cylinders and in most engines contains the combustion chambers.
the oil pan is a reservoir for oil and seals the lower portion of the block.
what is the function of the cylinder head?
oil distribution.
this is the housing for connecting rods and crankshaft.
this is the oil reservoir.
this is the housing for the camshaft and valves.
sealing the cylinders.
the coolant used to cool the engine flows through this.

Explanation:

The text states that the cylinder - head seals the top of the cylinders and in most engines contains the combustion chambers. Also, in an engine with an overhead camshaft configuration, the camshaft and valves are located in the cylinder head.

Answer:

This is the housing for the camshaft and valves., Sealing the cylinders.
