Description

Components of cylinder head

Spark plugs
Spark plugs are found in gasoline engines. They convey electricity to the combustion chamber to ignite the air/fuel mixture. The plugs usually mount on the cylinder head, with their tips going right into the combustion chamber. To ensure an airtight seal, the spark plug mounts are usually threaded.

cylinder head fuel injectors

1. Fuel injectors

On the cylinder head cover, you will also find fuel injectors. These are basically valves but electronically controlled. In a diesel engine, the injectors push fuel into the combustion chamber directly, with the help of the injection pump. Fuel injectors in a petrol engine use an indirect mechanism for the same function.

cylinder head camshaft

2. Cylinder Head Camshaft

Overhead camshaft or OVC cylinder heads house the camshaft. On these cylinder head types, the camshaft works the opening and closing of the valves in a timed manner. The crankshaft, which is one of the engine block components, drives the cylinder head camshaft using a belt.

3. Other Cylinder Head Parts

The cylinder head cover also contains pathways for coolant to cool the engine, and oil for lubrication purposes. Cylinder head port designs vary, just like the head designs do. Essentially, every type of construction aims at making the part as efficient as possible.

The performance of the cylinder head affects the operation of different cylinder block parts directly. The cylinder head cover gasket, too. When these two parts fail, the engine may not function as required.

A leak of coolant due to cracks or blown head gasket causes the engine to overheat. It can also reduce the compression ratio and make the vehicle to struggle uphill or during acceleration.

Therefore, inspect the head and the head gasket regularly, and fix or replace them if damaged. Also, the cylinder head parts such as valves, springs, and other components.
