Doosan Infracore Engine BG
Since 1958, Doosan Infracore has produced and developed diesel and natural gas engines for
commercial vehicles, military vehicles, construction equipment, generator sets and marine. Now,
Doosan introduces a new engine; the DP Series; V-type engines for generator sets. An easy
installation, high performance, fuel efficiency and durability are what engine users always need,
which are in the new DP series V-type engine. With Doosan’s engineering expertise, the new
engine obtain the maximum power output and fuel efficiency while maintaining mechanical type
that helps customers manage an engine more easily and conveniently. In addition, an engine
naming scheme was also redefined for easy and quick recognition of engine information. If you
look at the new DP series, the most appealing part is simple design minimizing an impact of
installation and maintenance. The eye-catching part is the glossy “New Green” color, which gives a
clean, luxurious image.
Doosan Infracore will keep striving to provide values to customers.
What is the DP series? The DP series is Doosan Infracore’s
new V type engines for generator
sets. DP stands for Doosan Power
generator engines. . The DP Series
is the result of Doosan’s efforts to
satisfy customer’s needs for the
best engine

Improved Fuel Efficiency Fuel consumption reduction thanks to stable combustion
One of the major cost parts for ownership is fuel cost. To solve this issue, the new DP series offer high fuel efficiency at the same time, power output is increased significantly. Thus, customers can enjoy with high fuel efficiency as well as higher power output than before.
Stable combustion can reduce unnecessary fuel consumption. By redesigning the intake air bend, the
DP series can save on fuel cost through stable combustion.

High Durability
Improved durability with reinforced exhaust manifold
A downtime of an engine is the most critical and time and cost consuming failure. Doosan Infracore
understands this hassle and difficulty well and tries to build enduring and durable engines so customers
can benefit from it. To achieve this, the rigidity of major parts - such as cylinder block, cylinder head,
crank shaft, con-rod, and piston ring - is improved by minimizing stress concentration and increasing
fatigue strength.
Newly designed cylinder block
Extend of R in Fillet part
Addition of Bracket
By applying HiSiMo as exhaust manifold material,
heat resistance is increased. Adding bracket at an
exhaust manifold prevents leak or crack due to
vibration.
Reinforced V belt for V12
High Performance Radiator
A V belt drives generator & water pump of an engine and supplies electricity to various electric devices
in the engine inside. To improve durability, the V belt was redesigned from the 4-row type to the 6-row
type. Likewise, the bearing of the fan drive was changed from single type to dual type to contribute to
the durability of an engine.
A radiator cools down the heat generated by an engine combustion. It is important because it prevents
overheat during operating an engine. The performance of the DP Series radiator was improved for
better durability, thanks to the redesigned intercooler & layout and material change.

For an easy installation, the DP series offers the following convenient features:
With the same performance, but the small-sized DP series can be installed more easily.
It can also secure more space in a generator set. Customers can find the installation much easier.
To secure larger space for an engine installation in a generator set
To enhance working convenience
To install an alternator of a generator set more easily
To move an engine more easily
To avoid interference with tools during installation Easy
When using 566 kW engine, the DP series V8 engine
provides larger space.
Easy installation in cold region
Redesigned engine mounting bracket
Repositioned turbochargers
Jacket water heater ports are required in cold regions to aid starting an engine. The DP series offers
in- let and out let of jacket water heater ports to increase the ease of installation. It also reinforce
durability by increase an ability of preheating in cold regions.
The engine mounting bracket was redesigned to avoid interference with tools during installation.
It can save working time and minimize safety accidents.
The turbochargers are repositioned from the top of the flywheel housing to the left and right
directions to a secure space for an alternator of generator set. This also prevents interference with
an wire when lifting an engine. The repositioned turbochargers aid in much easier installation.

Mechanical type engine
A mechanical type engine provides higher ease of maintenance and repair than an electronic type engine.
Considering this benefit, the DP series offers in mechanical type engine. In spite of the power increase, the
mechanical type offers easy management and easy operation with maximum power output.
Sufficient space between parts
Compliance with the American and Japanese Fire Services regulation
New belt cover and heat screen for safety and beatification
A fire caused by heat rarely occurs but can cause huge damage if it happens. The fuel
strainer was repositioned to secure sufficient space with the turbocharger so as to prevent fire caused
by overheat of an engine.
The material of the fuel line was changed from rubber to steel pipe to prevent damage by overheat. It
was adopted to comply with the Fire Services Act when operating generators in developed countries
such the U.S. In addition, rubber clip was applied to reduce vibration.

Safety and beautification are major factors as
well as performance and durability. The belt
cover and heat screen (protection from hot
exhaust manifold) are applied to prevent safety
accidents. It is also a condition to comply with the CE
Safety Regulation. The heat screen has 2 options;

Commonality of key parts
One of the worries of customers when they have a new engine is an increase in management cost caused
by change of parts. The DP series solve this issue by offering common major key parts. To do this,
management cost can be much saved. In the case of fuel systems, the existing injection pump, nozzle, and
high-pressure lines are carried over to the DP series.

New Color and Naming Optional Items
New Coloring Scheme
New Naming Scheme
The new coloring scheme was introduced for the new DP Series Engines. “New Green” color was selected
for the engine for a clean, stable, and luxurious look.
The engine naming scheme was redefined for easy & quick recognition. Customers can recognize fuel
type, application, displacement, number of cylinder, exhaust system by simply checking new engine name.
For example, DP222LA is for diesel power generator, 22L displacement, 12 cylinders, turbo intercooler
type, and version A.
