Cylinder Heads

The main task of the cylinder head is to close the combustion chamber of the engine from the top. The upper part of the engine is called the cylinder head, while the lower part is the engine block. The cylinder head sits on the engine and closes off the combustion chamber. The gap that remains between the cylinder head and the engine is completed by the head gasket.

Another task of the cylinder head is to ensure the constant lubrication of the cylinder. If the cylinders are not well-oiled, a smooth operation of the engine is not possible, which is why the cylinder head is an indispensable part of the function of the engine.

Components of a cylinder head in a gasoline engine

  • Inlet and exhaust ducts: These ensure that the exhaust gas can escape from the cylinders and the absorbed air-fuel mixture can get into the cylinders
  • Inlet and exhaust valves: This is where petrol engines suck an air-fuel mixture in, while exhaust gases are simultaneously transported to the exhaust system
  • Camshafts: A crankshaft-driven by the timing belt drives the camshafts. The camshafts are responsible for opening and closing the valves
  • Injectors: They ensure that the fuel is injected into the combustion chambers
  • Spark plugs: They initiate the combustion of the fuel

Air-cooled cylinder heads

Air-cooled cylinder heads are only cooled by the passing air. In addition, they are equipped with large cooling fins.

Among the advantages of this cooling method is that it ensures reliable functionality and can be built both very simply and inexpensively. Accordingly, the repairs to such cylinder heads are cheaper than repairs of water-cooled cylinder heads. In addition, you do not have to worry about freezing the cooling liquid when cooling the air.

Water-cooled cylinder heads

Most modern engines are cooled using water. For this purpose, a mixture of water and a frost agent is usually used as the cooling liquid. To cool the cylinder head, the coolant is passed through the cylinder head gasket into the cylinder head.

One of the advantages of this type of cooling is, above all, that the cooling liquid can absorb and also dissipate large amounts of heat. In addition, this cooling method is the most effective.
