4000 Series
A
new Generation of Engines
The Perkins' 4000 Series range of diesel engines was
designed in advance of today's uncompromising market place demands and to
create a new generation of engines for the 21st century.
Spanning the power band 261 bhp-2520 bhp (195kW-1879kW) the 4000 Series is
a true family of 6 and 8 cylinder in-line and 12 and 16 cylinder Vee
engines with a common design concept.
The 4000 Series features include exceptional power to weight ratios,
commonality of components, low fuel and oil consumptions, low levels of
gaseous emissions, overall performance and reliability which set new
standards for diesel engines.
The Perkins' 4000 Series has proved itself in the most arduous conditions
worldwide, from Greenland to the Arabian Deserts.
The 4000 Series is the result of a 10 year research programme to develop a
new design giving maximum reliability, durability and reduced running
costs.
The latest computer aided design technology was used to help create the
new range. Our engineers
concentrated on the combustion process to achieve the best fuel efficiency
and produce high power in a compact engine.
Central to the 4000 Series is a unique piston and cylinder design which
incorporates a unit fuel injector. All 4000 Series engines benefit from this proven design.
Individual cam/rocker operated unit injectors achieve high
pressures to ensure ultra-fine atomisation and controlled rapid combustion
resulting in low smoke and gaseous emissions, while producing high powers
per cylinder. The application
of unit injection eliminates the need for external high pressure fuel
pipes.
The pistons are aluminum alloy and incorporate gallery cooling thus
ensuring a thermally stable piston throughout the load and speed range.
This feature gives longer life of piston-rings and cylinder liners,
while decreasing the risk of potentially harmful carbon deposits.
The upper ring is wedge shaped running in a Ni-resist iron carrier, thus
eliminating top ring groove wear and ring sticking after extended periods
of running at high powers.
The 4000 Series cylinder and injection system are common throughout the
range allowing these engines to achieve the highest power outputs per
litre of cylinder capacity.
The range has externally mounted large capacity oil pumps to supply cool
pressurised oil to all working surfaces of the engine in addition to the
piston cooling jets. Wedge
shaped gudgeon pin bosses create large bearing areas, thus enabling high
power to be transmitted to robust induction hardened crankshafts.
Each cylinder has an individual four valve head to give optimised air
flows to these high specific power engines
High Power to
Weight Ratio
The 400 Series engines are noted for achieving high
power outputs per cylinder and offering high power to weight ratios.
The range provides power outputs normally only associated with much
larger engines, their compact size and low weight reduces shipping costs
and allows for easier installation. As
the number of cylinders for the output is lower than other engine designs,
the 4000 Series offers considerably reduced maintenance downtime and lower
parts costs.
Ease of
Servicing
Part of the initial design brief for the 4000 Series
was to provide excellent service access and ease of maintenance.
The individual cylinder heads can, for example, be easily removed.
The unit fuel injection system considerably aids reliability and
maintains overall engine efficiency while providing an easily serviced
system.
The 4000 Series benefits from the worldwide support of the Perkins
International dealer network, sophisticated parts support system and the
finest trained engineers.
Proven Power
The 4000 Series has been subject to continued
research and development using the latest techniques of diesel engine
design and engineering practice and are manufactured to the highest
quality standards.
At an early stage, advanced computer predictive techniques and finite
element analysis were extensively used. Application of such advanced engineering techniques allowed
our engineers to optimise component design, to achieve maximum reliability
and component life and thereby further contribute to operating efficiency.
Later in the development programme, specially constructed test chambers
allowed each stage of design and development to be fully tested in
rigorous operating conditions, allowing years of simulated usage to be
incorporated in basic design decisions.
The application of techniques such as photo elastic strain analysis
contributed significantly to the success of the development programme.
All engines are extensively test run and approved before leaving the
Perkins' factory and each engine is individually certified as complying
with Perkins' quality standards. As
the engines are extensively test run before despatch, they can be directly
installed on-site and will give full power on installation, without a
period of 'bedding-in'.
Application
Emission levels are low, typical smoke levels of
below 1 Bosch unit being achieved. Coupled
with their overall compact size, high power output and low fuel
consumption, the 4000 Series is an exceptional engine range.
Applications typically include:
Generating Sets, Pump Sets, Compressor Sets and Stone Crushers
