¡@DESIGN & CONSTRUCTION FEATURES |
| ¡@GENERAL |
The NIIGATA 32CLX diesel
engine is an ultra-modern, high power,
4-cycle, medium speed engine, designed to
provide reliable power for industrial or
marine service under long, arduous
conditions, anywhere throughout the world.
The design, based on many years of diesel
engine manufacture, incorporates maximum
reliability with minimum maintenance and
fuel consumption at low intial cost. |
| ¡@ |
¡@ |
|
¡@DESIGN AND CONSTRUCTION |
CYLINDER BLOCK (FRAME)
Rigid, box-girder section design with
mounting feet extended along the entire
length of the engine.
High grade cast iron, carrying the
crankshaft in main bearings, with
incorporated air intake trunk, lubricating
oil and coolant water channels.
All working parts inside the frame are
easily accessed through lightweight doors,
some incorporating explosion-proof valves,
provided at the front and rear of the frame.
¡@ |
¡@ |
CRANKSHAFT
One-piece, special forged steel,
manufactured by the 'R-R' process for
ensured strength.
Oil passages through the shaft provide
continuous oil feed to both connecting rod
bearings and pistons for optimum piston
crown cooling.
Balanced counterweights fitted on each web,
drastically reduces mechanical vibration.
A torsional vibration damper fitted to the
crankshaft's free end enhances crankshaft
and alternator shaft reliability.
¡@ |
MAIN BEARINGS
Shell type, steel-backed copper-lead alloy
with Pb-Snoverlay, housed in the frame and
caps.
This type of bearing provides ultra-strong
bearing force and long service life.
¡@ |
¡@ |
ANCHOR BEARING
A crankshaft anchor bearing, consisting of
the same shell type journal and thrust
bearings as the crankshaft, is supplied to
the coupling side of the frame for precise
crankshaft location and improved shaft
deflection.
¡@ |
CYLINDER HEADS AND VALVES
High grade cast iron cylinder heads provide
high thermal stress resistance.
Effective waterways are provided throughout
for totally adeguate coolant circulation.
The valve gear, with two intake and two
exhaust valves, is totally enclosed in a
cylinder head bonnet and lubricated by an
oil system independent from the engine oil
system.
The intake and exhaust manifolds are located
at the same side of the counter-camshaft and
arranged so that they may be left
undisturbed when one or more cylinder heads
are removed for partial disassembly.
A unique inlet and exhaust port arrangement
enables two types of valve to be used, one
being the inserted valve-seat type, of which
seat rings are inserted into the cylinder
head and directly cooled by the jacket
coolant.
The other available valve type is the
valve-cage type in which cages can be easily
withdrawn without necessitating removal of
the cylinder head, thereby providing easy
maintenance when using heavy fuel.
¡@ |
¡@ |
CONNECTING RODS
Made of special pressed steel, "I" section
connecting rod shank provide high regidity
and strength.
Large end bearing of a type similar to the
main bearing is secured by four high tensile
steel bolts.
Bush type small end bearing is
shrink-fitted.
The large-end 120-degree serrated matching
surfaces ensure high rigidity and serration
groove reliability.
¡@ |
CAMSHAFT(S)
Driven by a crankshaft gear through an idler
gear, individual case-hardened cams (intake,
exhaust, and fuel) are keyed onto the
camshaft.
The start-air distributor is located at the
shaft end.
The camshaft can be easily removed when
required. |
CYLINDER LINERS
Special cast iron, wet type liners are
precision-honed inside the bore.
Liners are secured to the top of the frame
by copper joints and are free to expand at
the lower end guide.
The upper section of the liners are provided
with a "Bore Cooling" system consisting of a
number of coolant passageways to ensure
moderate cooling.
¡@ |
¡@ |
FUEL INJECTION PUMPS
An individual Bosch type high pressure pump
is mounted at each cylinder, just above the
camshaft, and actuated by the camshaft's
fuel cam, enabling individual pump
adjustment for equal load distribution
across all cylinders.
¡@ |
FUEL INJECTORS
Fuel injectors consist of a nozzle and body.
When heavy fuel is used, nozzle temperature
is suitably controlled by the cylinder
coolant.
¡@ |
PISTONS
Two types of piston are avaliable, the
"composite type" with a heat-resistant steel
crown and ductile cast iron skirt, and the
ductile cast iron "mono-type" piston.
Both types are designed to reduce mechanical
and thermal stresses.
Cooling oil is induced into the cooling
chamber through the connecting rod for
optimum piston crown cooling.
Three compression and two oil scraper rings
are supplied.
Specially designed top rings minimize gas
blow-by through the ring gap.
Two coil expansion type oil scraper rings
ensure normal oil consumption. |
¡@ |
GOVERNOR
A camshaft-gear driven, Woodward-type
governor, controls the fuel pump's rackrod
through a interconnecting linkage.
Speed regulation is suitable for parallel
generator operation. Remote speed adjustment
is also provided for synchronization.
¡@ |
TURBOCHARGER(S)
Highly efficient, exhaust-gas driven, water
cooled, oil-bath lubricating type
turbocharger provided.
Either an air intake filter-silencer is
available, depending upon site conditions.
Either impulse or constant-pressure system
is provided, dependent upon engine
application.
