Also in some cases, it is manufactured from aluminium. While in Compression Ignition type engine (CI Engine), a fuel injector is mounted on the cylinder head.ДЄ cylinder head is usually made by casting or forging process in one piece of cast iron. While exhaust valve is mounted to escapes burnt exhaust gases to the atmosphere through the silencer.ДЄ spark plug is mounted if the engine is spark ignition type (SI Engine). To admit a fresh charge of the mixture inside the cylinder block, Intake Valve is mounted on a cylinder head. So, the leakage of the air-fuel mixture and burnt exhaust gases are totally arrested. The main function of a cylinder head is to seal the cylinder block from the upper side using a head gasket. The engine block is manufactured in one piece by casting process.ДЄ cylinder head is bolted to the upper side by placing cylinder head gasket while crankcase is bolted at the bottom of the cylinder block. To withstand high temperature and pressure, engine cylinder block is made from high grade cast iron. In air-cooled engines, fins are provided to cool the cylinder block. So, to carry out generated heat water jacket is provided in a water cooled engine. This charge is compressed and expanded hence piston can work further.Дue to fuel combustion, extreme heat is generated.

In-cylinder bore, a fresh charge of the air-fuelВ mixture is ignited. The main function of a cylinder is to allow the piston to reciprocate inside. This is the part where combustion of fuel is carried out.
