Cummins Every Time - Agriculture - Tier 3/Stage IIIA

Cummins new QSB3.3 doesn't just contradict conventional thinking about compact power - it rewrites the rules. The QSB3.3 delivers up to 110 horsepower (82 kW) in a much smaller and lighter package than any comparable 4.0- to 4.5-liter engine. Plus, it has the inherent durability you've come to expect from larger Cummins engines.

The innovative benefits of the QSB3.3 have been recognized with the prestigious title of "Diesel of the Year 2007" from a leading European publication. The engine has also been named as one of the "Top 100 New Products of 2006" by Construction Equipment Magazine in the U.S. These awards highlight the capability of the QSB3.3 to enhance the productivity of compact equipment.

With the QSB3.3, you get premium performance spanning the 80-110 hp (60-82 kW) ratings range for all your agricultural applications. It combines the proven reliability and minimal maintenance of the B3.3 with performance-enhancing features such as Cummins Quantum System electronic controls and a High Pressure Common Rail fuel system. A full range of options allow you to customize the QSB3.3 specifically to the equipment and environment where it will be used - whether it's on a farm or a fruit orchard.

To ensure that every QSB3.3 is perfectly matched to every piece of ag equipment, Cummins PowerMatch and Advisor provide expert assistance with your spec'ing and installation process.

Every QSB3.3 engine is covered by Cummins three-step warranty, one of the most comprehensive and simplest in the industry.

All ratings are intermittent unless otherwise noted. Additional ratings may be available. Check with your Cummins distributor or dealer. All ratings are Tier 3 capable.

^*Restricted rating.

The QSB3.3 combines the proven reliability of the B3.3 with Cummins Quantum System electronic controls and a High Pressure Common Rail fuel system for performance previously unavailable in an industrial engine this size.

Because the QSB3.3 maintains the fuel efficiency and minimal service requirements of the B3.3, it offers the same low operating costs.

The advanced features of the QSB3.3 provide many benefits whether you are running a farm, orchard or vineyard:

High Pressure Common Rail Fuel System - Dramatically reduces engine noise while providing more responsive power and better fuel efficiency at every rpm. The fuel system is capable of delivering high injection pressure of 800-1100 bar (11,600-16,000 psi).
In-Cylinder Combustion Technology - Meets Tier 3/Stage IIIA emissions standards without external components; is compatible with high-sulfur fuels for worldwide use.
Heavy-Duty Durability - The camshaft, crankshaft and rods are all made of forged steel and the pistons are a one-piece aluminum design for strength and durability.
Full-Authority Electronic Controls - Optimize engine performance and provide seamless integration with other components. Include advanced diagnostics.
Cast Iron Cylinder Block - Parent bore design with deep skirts and structural ribs to increase stiffness and resist torsional stresses.
Two-Valve Crossflow Cylinder Head - Designed to improve breathing and resist thermal fatigue.
Simple Wastegated Turbocharger - Wastegated for better low-speed performance and high-speed boost.

The small footprint and compact size of the QSB3.3 make it an excellent fit for a wide variety of agricultural equipment. Options for the QSB3.3 include:

Structural pan
Fan height and ratio
SAE "A" PTO options
SAE #3 or #4 flywheel housings
Intake heater and other cold-start aids
One-side service capability
Hydraulic pump drive with your choice of tooth splines
Front or rear sump oil pan
And more

See your local Cummins distributor or dealer for a complete listing.

Minimum maintenance has been designed into every QSB3.3 engine, with oil changes up to 500 hour/6-month intervals. To make service even easier, the lube filter, fuel filter, oil fill (top or side) and dipstick can all be located on the same side.

For complete maintenance information, please consult your Owner's Manual or Operations and Maintenance Manual.

The base warranty includes full coverage on every QSB3.3 engine and branded components, including electrics such as starters and alternators for unlimited hours during the first year of operation, extending through 2 years or 2,000 hours (whichever comes first). The base warranty also includes 3-year/10,000-hour standard protection on major components.

Three simple steps explain everything you need to know:

Step One: Full coverage on all Cummins industrial engines and branded components with unlimited hours during the first year of operation. This includes Cummins branded electrics such as alternators, starters, etc.

Step Two: Full coverage is extended for the second year, up to 2,000 hours of operation. Total hours are cumulative from the time the engine goes in service.

Step Three: Major components coverage including block, crankshaft, camshaft and rods on all products for the third year or up to 10,000 hours of operation.

Cummins PowerMatch helps OEMs optimize engine performance to lower fuel consumption, increase operator satisfaction, improve equipment life and protect the customer's investment. Advanced electronics are used to enhance power curves and trim ratings, matching the duty cycle while taking into account work environment, load factors, ambient temperature and altitude. PowerMatch can also be used to create a unique torque curve, set up alternate torque curves, alternate governor settings or set up engine protection features.

Getting every installation right - the first time - is as important to Cummins as it is to you. Cummins Advisor helps ensure that we get it right, every time. It recommends the best engine and rating match for the equipment and operating conditions based on load factors, climates, duty cycle and equipment usage. It then builds a virtual model of the intake, exhaust, cooling, fuel and mounting systems. When Advisor identifies an issue, it lists acceptable alternatives. This allows changes while the equipment design is still "on paper," ensuring optimum performance while minimizing costs.
