Cummins - The Tier 4 Technology Leader.
You can be confident that Cummins will deliver better system integration every time with the most dependable power solutions for Tier 4.
Our Tier 4 Interim technology solution builds upon the proven durability of our Tier 3 base engines while adding worldwide experience and leadership in key enabling technologies to meet EPA Tier 4 Interim and European Stage IIIB mobile off-highway emissions standards for the 174 – 751 horsepower (130 – 560 kW) range taking effect in 2011. Cummins is the only engine manufacturer with a single, integrated system that encompasses critical subsystems from air intake to exhaust aftertreatment.
EPA Tier 4 Interim and EU Stage IIIB emission regulations will take effect on January 1, 2011 across the 174-751 hp (130-560 kW) power categories with 90% particulate matter (PM) and 45% oxides of nitrogen (NOx) reductions.
Cummins Tier 4 Interim solution from the MidRange QSB6.7 to the Heavy-Duty QSX15 engine will utilize common Tier 4 subsystem architecture with cooled Exhaust Gas Recirculation (EGR) and Cummins Particulate Filter as the core technologies. Engine enhancements will include a new Cummins Direct Flow air filtration system, the use of Cummins Variable Geometry Turbocharger (VGT™) and a crankcase ventilation system with a highly-efficient coalescing filter. All components are managed by a single Electronic Control Module providing a completely integrated system.
Beginning January 1, 2012, the Tier 4 Interim and Stage IIIB regulations will take effect for the 75-173 hp (56-129 kW) power categories.
The next generation 4-cylinder QSB engines retain the same 3.3-liter and 4.5-liter proven platforms and will be supplied as a fully integrated air-intake to exhaust aftertreatment system. Both the cooled EGR system and the Particulate Aftertreatment unit have been specifically developed as a more compact and simplified version of the Tier 4 Interim technology of the 6-cylinder QSB6.7 engine. An upgraded turbocharger with electronic control will be utilized to manage EGR flow across the entire engine rpm speed range.

A Series
Cummins A Series engines give equipment manufacturers a big advantage. Every one of the A Series engine ratings is compliant with Tier 4 Interim which means no change to the engine through 2012. We also meet Stage IIIA regulations through 2017.
Cummins has been able to meet these standards by using Cummins in-cylinder technology, a technology that provides the highest reliability and performance possible.

QSM
The QSM uses advanced electronic controls to meet the toughest
standards without compromising anything. Exceptional fuel
efficiency, durability, dependability and the highest power-to-weight
ratio in its class are still trademark QSM qualities. Plus,
the QSM now runs quieter and cleaner.
The QSM engine comes with the same powerful Electronic Control
Module (ECM) as our larger QSX and QSK engines. Using input
from sensors located throughout the engine, it governs the
timing and metering of fuel to the engine. Fuel is injected
into the power cylinder using Cummins dual-pulse technology.
This injection method helps reduce noise levels as it increases
responsiveness and improves fuel efficiency.
Reaping The Rewards Of High Technology. The onboard electronics
of the Quantum System give equipment operators greater control
over operating speeds, gear selection and more. Including
the ability to switch to an alternate power curve, adjust
the low idle and reset intermediate speed governors to match
job site needs. Plus, the ECM can be mounted in two different
locations on the engine, for easy equipment integration.

your local branch for more information or to order.

QSX
The QSX is the first diesel of the 21st century, with totally
integrated electronics that link engine and equipment performance
like never before. Not only does the QSX meet Tier 2 emissions,
it will meet proposed Tier 3 requirements with just minor
modifications. Taking equipment manufacturers past 2010.
The Advantage Of Dual Overhead Cams. The first cam drives
the high-pressure fuel injection system, capable of pressures
up to 30,000 psi. Higher injection pressure means greater
combustion efficiency. So your customers get more power with
fewer emissions.
The second cam operates the intake and exhaust valves, plus
it has a set of lobes dedicated to the operation of an integrated
engine brake, called the Intebrake ™, which adds extra
braking capacity while reducing service brake wear and extending
maintenance intervals.

QSK19
The QSK19 is a powerful example of Cummins
Quantum System technology at work, with state-of-the-art electronics
capable of self-diagnostics, prognostics and more. The latest
version of this proven performer takes technology to the next
level, meeting Tier 2 emissions standards without compromise.
Fuel economy, horsepower, torque rise, transient response
and service intervals match the high levels achieved by Tier
1 models of the QSK19. It’s an engine that goes beyond
meeting government standards to meet the toughest standards
of all…the performance demands of your customers.
The QSK19’s high-pressure injection system and electronic
controls ensure clean, powerful and efficient operation. The
ECM continuously monitors data from strategically placed sensors
within the engine, optimizing the fuel-to-air mixture for
maximum combustion. Fuel is injected at pressures exceeding
25,000 psi. This results in better utilization of fuel with
fewer emissions. Getting more energy out of every drop of
diesel fuel also results in more power.
The innovative QSK19 is designed for maximum utilization
with minimum maintenance, for example, the articulated pistons.
Not only will they last 30% longer, until the first rebuild,
but your customers will also get an additional 30% longer
life after the first rebuild.
The lubrication system and monitoring program give standard
scheduled oil and filter changes at 250 hours. Even the oil
seals have been engineered so they are never exposed to contaminants.
The result is virtually leak-free operation.

local branch for more information or to order.

QSK23
The QSK23 delivers the power you need and
the low operational costs that today’s business climate
demands. It combines the high-tech electronic features of
all of our QSK engines with the proven power cylinder design
of our QST30 and QSK78 engines, for superior reliability and
durability.
Smart torque across the rpm range gives haul trucks the power
to pull away from the shovel fast and maintain speed on the
uphill climb out of a pit. A high-pressure injection (HPI)
system injects fuel at 29,000 psi for the best fuel economy
of any engine in its class, while maintaining low emissions.
The QSK23 meets current EPA and European standards for all
horsepower ratings today and will be developed for Tier III
with minimal installation impact.
The QSK23 shares electronic components with all of our other
QSK engines, from 19-78 liters in size. Sensors located throughout
the engine and equipment subsystems constantly send a stream
of information to the ECM, so the air/fuel mixture is always
optimized to the operating conditions. The HPI system is so
sophisticated that it adjusts to fuel quality.
The QSK23 is based on an engine platform that’s been
proven in industrial applications for over 20 years. The block
is one-piece cast iron, with wide cylinder spacing for long
life and excellent rebuildability. Both the liner and the
piston are made of ferrous cast ductile iron, for even expansion
and contraction during thermal cycles. The head has a new
seven-bolt design to handle cylinder and injection pressures
reaching 29,000 psi. From the robust (105mm) camshaft to the
ceramic top ring on the piston to an oil pump with 15% more
capacity than in previous years, every part is designed for
maximum lift.

QST30
The QST30 delivers more power and more torque in a smaller
package than competitive diesels. So whether you are looking
at buying new or repowering, the QST30 fits almost any piece
of equipment in the pit.
The QST30 is an excellent choice to replace a number of
engines – including some of our own. It’s got
significantly more power, as much as 50% longer life-to-rebuild
and better fuel economy than the Cummins V28, even though
it is virtually the same size. Repowers are available with
air-to-air cooling (for equipment which has to meet emissions
standards) or jacket-water after cooling (for non-emissionized
equipment).
If you have an older competitive engine, you’ll find
that replacing it with the QST30 gives you up to 25% more
power and torque, better fuel economy and longer service intervals,
for increased productivity with lower costs.

local branch for more information or to order.
