Heavy-Duty Features And Benefits
Better. Where It Counts.
n
Continuous Improvement – In 2013 we have
refined our technology and our complete
on-highway line-up, including the Heavy-Duty
ISX15 and ISX12. Our 2013 engines meet 2014
Environmental Protection Agency (EPA) and
United States Department of Transportation (DOT)
regulations for fuel economy and greenhouse gas
(GHG) reduction, a year ahead of schedule. Our
Cummins 2013 engines are also equipped with
the required On-Board Diagnostics (OBD) system
that monitors and ensures optimal performance
of the emissions system. If the system detects
any emissions related malfunctions, it will alert the
operator to these detected malfunctions through
a dash lamp known as the Malfunction Indicator
Lamp (MIL).
n
Better Fuel Economy – Cummins has taken our
industry-leading fuel economy and improved it
by up to 2% in 2013, versus 2010 engines, by
reducing parasitic losses, optimizing combustion,
improving component efficiencies and needing
fewer active aftertreatment regenerations. Better
fuel economy means lower operating cost and
maximized profits.
n

800 lb-ft (1085 N•m) clutch engagement torque.
n
ISX15 Ratings – SmartTorque ratings continue
to be offered, adding up to 200 lb-ft of extra
torque in the top two gears so drivers can
maintain road speed going up steep grades with
fewer downshifts and better fuel economy. Plus,
vocational ratings are available, delivering extra
torque in lower gears for dump trucks, mixers and
refuse vehicles.
n
ISX12 Ratings – The ISX12 is ideal in operations
calling for a compact heavy-duty engine. The
ISX12 Vocational ratings are engineered to provide
additional torque in the lower gear ranges, where
it’s needed most. We offer multiple options,
including both Front- and Rear Engine Power TakeOff (FEPTO and REPTO) units and a selection of
hydraulic drive options. This versatility makes the
ISX12 an ideal choice for rear- and front-pouring
mixers as well as dump trucks and refuse haulers.
We also offer standard ratings, with engine software
configurations designed to deliver the precise
combination of fuel economy and performance to
meet the needs of regional and LTL fleets.
Maintenance
n
Maintenance Intervals – We have increased our
maintenance intervals for both fuel and oil.
Oil-change intervals for the 2013 ISX15 and ISX12
can be extended by 5,000 miles (8,000 km) with
the use of Valvoline™ Premium Blue
®
oil
in normal-duty and light-duty cycle operation,
helping to maximize uptime while reducing
maintenance costs.

SmartTorque
Putting Technology In High Gear
SmartTorque technology is a torque
enhancement system that gives fleets and
owner/operators massive hill-pulling torque. And,
at the same time, delivers up to 3% savings on
fuel costs. Here’s how it works:
The electronic control module monitors engine
speed, load and gear position. When the driver
shifts into the top two gears, SmartTorque
automatically “kicks it up”, unleashing as much
as 200 extra lb-ft of torque.
Though SmartTorque increases power
significantly, that’s not a consideration when
spec’ing the transmission. For example, if
SmartTorque boosts engine torque to 1850
lb-ft, the transmission can be spec’d for a
lower torque rating. Saving both the weight
and expense of a beefier transmission. Yet
with SmartTorque’s extra power, drivers get up
steeper hills with fewer downshifts, saving fuel,
decreasing trip times and reducing driver fatigue.
So destinations are reached more economically,
faster and safer.
Page 12

Load-Based Speed Control
Cummins Load-Based Speed Control (LBSC)
is a patented electronic feature on ISX15
and ISX12 engines that helps drivers achieve
higher fuel economy without compromising
performance.
This Cummins exclusive feature automatically
adjusts the engine operating range to match the
load on board and the route.
It optimizes engine rpm during normal driving
conditions by governing the engine speed to
encourage shifting in the most fuel-efficient
ranges. At the same time, it continuously
monitors vehicle operating conditions and allows
access to an extended engine operating range
every time it senses the need. For example:
n On a grade exceeding 2%
n During sharp turns when tire scrub may occur
n When carrying a load in excess of 80,000 lb
LBSC also does not limit engine speed during gear
changes or when operating in the top two gears.
Load-Based Speed Control lowers the average
engine revs/mile (kilometer). This has many
benefits:
n Improved fuel economy
n Reduced parasitic losses due to cycling of
engine accessories (such as the fan)
n Lower engine noise in parking lots and
residential areas
n Improved engine durability

Cummins Westport Inc.
The Natural Choice
Cummins Westport Inc. is a 50/50 joint venture
between Cummins Inc. and Westport Innovations,
created to develop, manufacture and market
low-emissions high-performance alternative
fuel engines worldwide. The vision of Cummins
Westport Inc. is to be the world’s leading provider
of clean gaseous-fueled engines that deliver an
economic solution to bus and truck customers.
Cummins Westport natural gas engines are
manufactured by Cummins and sold and serviced
by the global Cummins network with Cummins
Parts and Service and Warranty support. Optional
extended warranty plans are also available.
The ISL G and ISX12 G share major engine
components with their diesel counterparts,
ensuring parts durability and availability.
The ISL G and ISX12 G operate on 100% clean
burning natural gas, which can be carried on
the vehicle in either compressed natural gas
(CNG) or liquefied natural gas (LNG) form. They
can also operate on renewable natural gas or
biomethane that meets fuel quality specifications.
Both engines meet current U.S. Environmental
Protection Agency (EPA) and California Air
Resource Board (ARB) emission standards and
2014 EPA and U.S. Department of Transportation
(DOT) fuel efficiency and greenhouse gas (GHG)
regulations.
The use of stoichiometric combustion technology
and a Three-Way Catalyst exhaust aftertreatment
creates low emissions without the need for Diesel
Particulate Filters (DPF) or Selective Catalytic
Reduction (SCR) systems.
The ISX12 G and ISL G are available from leading
truck, urban transit, and school bus OEMs in a
variety of applications.
Page 21

Natural Gas Features And Benefits
n Lower Operating Costs – In high fuel use
applications, the combination of lower alternative
fuel costs, improved fuel economy and lower
incremental maintenance costs make it possible to
save valuable dollars with a natural gas-powered
fleet.
n Performance – The high torque and broad power
band of the ISL G, with ratings from 250-320 hp
provide excellent performance when matched to
various automatic transmissions in vocational,
medium-duty and heavy-duty trucks up to
66,000 lb GVW, as well as urban transit, shuttle and
school bus applications. The ISX12 G, with ratings
from 320-400 hp, is designed for a wide variety of
vehicles, including regional-haul trucks/tractors up
to 80,000 lb GVW, vocational trucks and refuse
applications. The ISX12 G will offer optional engine
braking, plus automatic and manual transmission
options.
n Maintenance-Free Aftertreatment – Stoichiometric
combustion with cooled Exhaust Gas Recirculation
(EGR) provides the ideal combustion process in
which fuel and oxygen are completely consumed,
leaving no unburned fuel or oxygen in the exhaust
stream. This advanced combustion technology
enables the use of a Three-Way Catalyst (TWC),
which is a passive device packaged as a muffler
that is maintenance free. It does not require a
particulate filter or Selective Catalytic Reduction
(SCR) system using Diesel Exhaust Fluid (DEF).
n Cooled Exhaust Gas Recirculation (EGR)
Combustion Technology – Takes a measured
quantity of exhaust gas and passes it through a
cooler to reduce the temperature before mixing
it with fuel and the incoming air charge to the
cylinder. The use of cooled EGR in combination with
stoichiometric combustion improves power density
and fuel economy versus lean-burn or traditional
stoichiometric natural gas engines.
Page 22

n Electronic Control Module - The ECM constantly
monitors and controls the engine actuators,
sensors, fuel system and ignition system. It
provides OEM and end users with the ability to
tailor performance of the engine to fit the vehicle
mission. It also has full interface capability to
Cummins INSITE™ and QuickCheck diagnostic
service tools.

Expert Diagnostic System (EDS)
An innovative engine diagnostic tool, Expert
Diagnostic System (EDS) uses historical trends
and advises in the simplest terms the most likely
steps needed to resolve engine problems. This
helps the technician get to the problem quickly,
reducing vehicle downtime and saving money
for everyone. When entering required data and
answering some questions, EDS will recommend
to the technician the most likely solution for
the repair. EDS is the “Next Generation”
troubleshooting system that continually learns
from any repair made. Each service event will be
tracked using a Diagnostic Session Identification
(DSID) which will then record all service history
for a given Cummins Engine Serial Number
(ESN). Warranty administrators will also benefit
from this tool since EDS is designed to simplify
the warranty claim process. You can upload
the diagnostic Standard Repair Times (SRTs) to
RAPIDSERVE Web by entering the DSID into the
first page of the RAPIDSERVE Web Claim.
EDS is a web-based system and can be found
at insite.cummins.com under “Related Tools”.
Training courses cover a variety of roles so it will
help guide everyone to mastering the full benefits
of this great tool. The EDS user guide, FAQs and
other related information can be found on the
EDS page.
For more information, visit
insite.cummins.com/insite/eds/, contact your
local Cummins distributor or call us toll-free at

CUMPAS
Cummins provides CUMPAS (Cummins Parts
and Service) to parts dealers in North America.
This electronic tool enhances a dealer’s ability to
work with the Cummins distributor network.

to the Cummins distributor responsible for the
territory where the dealer is located. CUMPAS
saves time and greatly reduces the need for the
dealer to call or fax the distributor. All the dealer
needs is a computer and access to the Internet.
Cummins dealers benefit by using CUMPAS to
tie electronically into the distributor’s Business
Management System. The dealer can inquire
about part pricing, availability, supercession,
order status, invoice detail and back orders.
CUMPAS facilitates stock orders as well as
branch, emergency and warranty orders. It also
enables order downloading from the dealer’s own
business system. In addition to Parts Ordering
and its many features, CUMPAS provides Core
Processing and Management Reports, including
the latest, Price File Extract. The CUMPAS link to
QuickServe
®
Online makes it easy to look up part
numbers in an online catalog and transfer them
to CUMPAS via an electronic shopping cart.
To sign up for CUMPAS, dealers simply need
to contact their Cummins distributor and
request access. The distributor provides the
registration and authentication, as well as
account information for online access. CUMPAS
provides training tutorials online as well, so dealer
personnel receive training at their convenience

to technicians but other learning “paths” are
available for parts personnel on Cummins latest
products.

Vehicle Mission Simulation
™
(VMS)
Vehicle Mission Simulation (VMS) is a program
developed by Cummins that evaluates the
performance of various engines and power
train configurations. VMS is ideally suited for
comparing different vehicle specifications for
new equipment and predicting performance
for those specifications so the customer can
make the best decision for their new equipment.
The program features the prediction of steadystate performance and route simulation
capability, including starts, stops, gear changes,
observance of speed limits, ascending and
descending grades, braking and idling.
While the program has been designed to reflect
an accurate representation of the vehicle being
configured, it does not represent a guarantee of
actual performance, as conditions may vary.
Contact your local Cummins distributor if you
need a detailed analysis performed with VMS.
