Our dual-tier strategy for

addressing IMO III takes proven
engine technology and adds an
advanced aftertreatment which
allows SCR to be “paused”
when operating in less regulated
waters. The system doesn’t
require use of low-sulfur fuel and
has the most competitive DEF
usage in its class. Maximum
flexibility, performance and
convenience. Minimum fluid
usage, maintenance and cost.

EXPERIENCE THAT
SPANS THE GLOBE.
GHANA PORTS & HARBOUR AUTHORITY

Ghana’s dramatic increase in cargo traffic has prompted the addition of three new ship-
docking tugs . Each one is 32.8 by 12.9 meters with a depth of 5.37 meters and a pair of
Cummins QSK95 engines power a pair of Rolls Royce US2555 P30 FP azimuth thrusters.
This combination gives the tugs an 80-ton or greater bollard pull and speeds up to 13 knots.
A dedicated fire pump engine provides the required power to meet Fi-Fi 1 standards with
Cummins QSK38-M 1595 BHP (1190 kW) variable speed at 1800 RPM while also providing a
protective water spray.
Electrical requirements of each tug are met with a pair of Cummins QSB7DM-powered
generators producing 170 Kva 136 kWe at 1500 RPM 50 Hz.

POLISH MULTIPURPOSE VESSELS

Poland’s impressive history in maritime research continues to grow with the delivery of two
new multipurpose vessels. In addition to servicing Polish navigational aids and ice breaking,
these diesel-electric powered craft are equipped for towing ships in emergencies. A major
focus of their work is in conduction hydrographic research on water quality and depth contours.
The vessels are fitted out alongside with three 1359 kWe generators each powered by
an IMO Tier III compliant Cummins QSK50 diesel that will turn at 1800 RPM. The green
technology has been well proven on off-shore support vessels where, depending on demand,
the ships can operate on one, two, or three generators.

68 MARINE PRODUCTS GUIDE CUMMINS INC.

Cummins offers factory remanufactured parts for all engine models.
In addition Cummins remanufactures Short Blocks, Long Blocks
and Heavy-Duty L10, M, N and ISX/QSX engine platforms, as well
as, MidRange B, C and ISL/QSL engine platforms.
The following describes the measures Cummins takes to
remanufacture its engines and parts, creating a product that is
comparable to a new Cummins product.
» Core Acceptance: A great benefit of Cummins
remanufacturing is that you can get money back for exchanging
your worn out engine or part. Any Cummins authorized repair
facility worldwide can perform the simple visual inspection
on your old part and give you immediate credit toward its
replacement.
» Disassembly: Engines and parts are completely disassembled
with great care to protect and prepare key components for
processing — right down to the last screw, nut, bolt and spring.
» Cleaning: Each part is carefully cleaned using the latest
technology to remove debris without removing any metal,
including the use of dry ice, enzymes and lasers for specialized
cleaning needs.
» Inspection: The latest technology, including ultrasonic
inspection, is just one of the many methods used to verify that
every ReCon part meets original factory specifications.
» Restoration: Cummins uses a variety of techniques to ensure
that parts meet original specifications or improved standards
of performance. If a part doesn’t meet specifications, it is
scrapped and replaced with a new Genuine Cummins part. Any
upgrades or supercessions that have taken place in the years
since the original part was made will be included as part of the
Cummins remanufacturing process.
» Testing: Validation testing using fail-safe processes verifies
that the performance and reliability of the finished product meet
Cummins standards.
» Reintroduction: Once the remanufacturing process is
complete Cummins engines and parts are ready to be
reintroduced into the field.
Genuine Cummins New and ReCon Parts are built to meet or
exceed your engine’s original specifications for performance,
reliability and durability. For more information about Cummins
ReCon products, please visit cummins.com or contact your local
Cummins distributor or authorized dealer.

subject to load, speed and application. Sleeve bearings are split type,
to permit easy access for maintenance. Subject to frame size, speed
and inclination they may be self-lubricated or force lubricated.

EXCITATION SYSTEM
Our alternators are equipped with brushless excitation; the auxiliary
winding supplies the automatic voltage regulator (AVR) with sufficient
power to ensure short-circuit levels of > 3x rated current. Subject to
frame size and bearing arrangement, PMG is also available.

AUTOMATIC VOLTAGE REGULATOR

A range of digital Automatic Voltage Regulators (AVR) are available to
meet varying application requirements. Typical AVR features include:
» Voltage regulation in island mode (+/–0.5 percent)
» Reactive load sharing by static droop or cross-current compensation
» U/f characteristic for applications with floating frequency
» Under/over-excitation voltage protection
» Excitation fault monitoring
» Fast PID response for high-class regulation characteristic.

INSULATION
All windings are bar-wound type and conform to either Class F or Class H
thermal insulation. Increased machine life and reliability is ensured through

CENTINEL™

Available as an aftermarket kit for K Series

engines or installed as a factory option on MCRS
engines, CENTINEL eliminates or extends oil
change intervals by burning used oil and replacing
it with clean oil.
The CENTINEL Advanced Engine Oil Management System automates
oil changes. While the equipment is running, CENTINEL monitors the
engine’s duty cycle. At precise intervals, it bleeds off a small amount
of used oil and sends it to the fuel tank, where it blends with diesel
fuel and is burned during combustion.

CENTINEL allows equipment to work up to 4,000 hours between

service events. Depending on the duty cycle, that could eliminate
15–20 oil changes from current maintenance schedules.

» Reduces downtime and the cost of oil change service

» Reduces the risk of engine damage due to poor oil change
maintenance practice

CUMMINS INC. MARINE PRODUCTS GUIDE 111

ELIMINATOR™

Available on the
KTA38, KTA50,
and all QSK MCRS
engines, ELIMINATOR
is a combination full-flow and centrifugal system
that incorporates a permanent stainless steel core
that eliminates the need for disposable oil filters.
ELIMINATOR consists of a two-stage filter media system. The first filter
screens for particles as small as 20 microns, while a centrifugal separator
constantly spins, depositing the heaviest particles on a replaceable liner.

Because ELIMINATOR uses the oil pressure in the lubricating system to spin
the centrifugal separator, there is no additional load on the engine, with no
drain on power or fuel economy. This option lowers the cost of operation by:

» Eliminating the recurring cost and maintenance of spin-on filters

» Reducing downtime for filter changes
» Eliminating disposal cost of used filter elements
» Improving filtration and reducing component wear which can
extend overhaul periods
» Extending oil change intervals when used concurrently with oil
sampling and CENTINEL

ELIMINATOR satisfies most Marine Classification Society

requirements for duplex filters.

REFERENCE
MATERIALS

FUEL CONSUMPTION
One of the most commonly asked customer
questions is, “How much fuel will that engine use
in my boat?” The answer may be derived using
any of the following four prediction methods:
» Advertised fuel consumption at rated power (single point)
» Average fuel consumption over a standard test cycle
» Average fuel consumption over a specific duty cycle
» Surrogate vessel comparison

The Marine Products Guide lists the average fuel consumption at rated
power and over standard cycles recommended by the International Standard
Organization ISO 8178 E3 standard test cycle for propulsion commercial
applications, E5 for recreational applications and D2 for auxiliary applications.
It represents the fuel consumption for a typical marine customer, as defined
by ISO.

Fuel consumption values from engine control modules and displayed

on instrument panels are not absolute. Tolerance varies with speed
and load, but is generally less than +/–5 percent when operating within
30 percent of rated power.

Please note: fuel consumption calculations are based on fuel of 35° API
gravity at 16°C (60°F) having an LHV of 42,780 KJ/KG (18,390 BTU/lb)
when used at 29°C (85°F) and weighing 838.9 g/liter (7.001 lb/US gal)
with LTA when available.

marine vessels.

EU: The Nonroad Mobile Machinery Directive regulates exhaust emissions

from diesel engines installed on inland waterway vessels operating in the
European Union. The Recreational Craft Directive regulates noise and
