Components of high speed diesel power plant consists of the following systems:
Fuel
supply system: It
consists of fuel tank for the storage of fuel, fuel filters and pumps to
transfer and inject the fuel. The fuel ml may be supplied at the plant site by
trucks, rail, road, tank, cars etc.
Air
intake and exhaust system: It
consists of pipes for the y of air and exhaust of the gases. Filters are
provided to remove dust etc. from the incoming air. In the exhaust system
silencer is provided to reduce the noise.
Filters
may be of dry type (made up of cloth, felt, glass, wool etc.) It oil bath type.
In oil bath type of filters the air is swept over or through a bath of oil in
order that the particles of dust get coated, of the air intake systems are as
follows:
i.
To clean
the air intake supply.
ii.
To
silence the intake air.
(iii) To supply air for super charging.
The
Intake system must cause a minimum pressure loss to avoid reducing engine
capacity and raising the specific fuel consumption. Filters must be cleaned
periodically to prevent pressure loss from clogging. Silencers must be used on
some systems to reduce high velocity air noises.
Cooling
system: This system provides a
proper amount of water circulation all around the engines to keep the
temperature at reasonable level. Pumps are used to discharge the water inside
and the hot water leaving the jacket is cooled in cooling ponds or other
devices and is recalculated again.
Lubricating
system: Lubrication is essential
to reduce friction and wear of the rubbing parts. It includes lubricating oil
tank, pumps, filters and lubricating oil cooler.
Starting
system: For the initial starting of engine the
various devices used is compressed air, battery, electric motor or
self-starter.
