Cylinder head is one of the main components of the diesel generator, diesel generator set is mainly composed of diesel engine, synchronous
generator, control panel, electrical control equipment and various accessories,
its role is largely closed to the upper body, and with the pistons' parts such
as cylinder combustion chamber space, as well as the installation of nozzle,
intake valve and exhaust valve and rocker arm assembly parts, to ensure the
supply high pressure atomized diesel combustion chamber and the inlet and
exhaust process smoothly. Water-cooled diesel engine cylinder head is not within
the cooling water and lubricating oil channels.
Cylinder head is installed on the top of the cylinder block, from
the upper seal cylinder and combustion chamber. It often come in contact with
high temperature and high pressure gas, so bear a lot of heat load and
mechanical load. Water-cooled engine cylinder cover internal cooling jacket,
cooling of the cooling hole of the bottom of cylinder head and cylinder hole.
Use of circulating water to cool the combustion chamber high temperature parts,
etc. The cylinder head is also equipped with inlet and exhaust valve seat, valve
guide hole, used for installation of inlet and exhaust valves, and inlet channel
and the exhaust pipe, etc. Gasoline engine has to install the spark plug hole on
cylinder head processing, and processing with the installation of fuel injector
holes on the diesel cylinder head. Overhead of concave wheel on engine cylinder
cover have a concave wheel bearing hole processing, used to install the concave
wheel axle. Cylinder head generally USES gray cast iron or alloy cast iron, cast
aluminum alloy of good thermal conductivity, is helpful to improve the
compression ratio. So aluminium alloy cylinder head in recent years have been
used more and more. Cylinder head is part of the combustion chamber, the shape
of combustion chamber had a great influence on the engine work, because of the
gasoline engine and diesel engine combustion in a different way, the component
part of the combustion chamber on cylinder head difference is bigger. Gasoline
engine's combustion chamber, mainly on the cylinder head and combustion chamber
of diesel engine in the piston at the top of the pit.
I hope this suggest can help you when the diesel generator have fault. I also hope to have the opportunity to cooperate with you.
