B3.3 60-85 hp (45-63 kW)
Cummins B3.3 is designed for dependable, long-lasting
performance. With Tier 4 Interim ratings from 60 to
85 hp (45-63 kW), Cummins solution meets all emissions
regulations while maintaining a simple, compact and
cost-effective design with fuel-efficient performance for
compact equipment.
QSB3.3 75-120 hp (56-90 kW)
The QSB3.3 is one of the most powerful engines in its
class, comparable to 4- and 5-liter engines in a much
smaller package. Ratings reach as high as 120 hp
(90 kW) with a peak torque of 306 lb-ft (415 N•m). The
QSB3.3 combines superior performance with reduced
emissions.
QSB4.5 110-163 hp (82-122 kW)
With power output ranging from 110 to 163 hp
(82-122 kW), the four-cylinder Cummins QSB4.5 delivers
performance comparable to some six-cylinder engines,
without excess bulk and weight. Power output and
engine response are sufficient to handle the highest load
factors, and the rugged dependability of the QSB4.5
has been proven under the most difficult operating
environments.
QSB6.7 140-300 hp (104-224 kW)
Sometimes you just need the extra power and durability
of a six-cylinder diesel. And you can’t do better than the
Cummins QSB6.7. With a 140- to 300-hp (104-224 kW)
range and its proven design, the QSB6.7 has been delivering
dependable performance and exceptional reliability for years.

QSL9 240-400 hp (179-298 kW)
Built on a heritage of reliability and durability, with power
output ranges from 240 to 400 hp (179-298 kW), the
Cummins QSL9 delivers improved performance for a wide
range of agricultural solutions.
QSX11.9 300-500 hp (224-373 kW)
The QSX11.9 has one of the highest power-to-weight
ratios in its class, and its remarkable torque rise (up to
50 percent) enables the QSX11.9 to more quickly take
full advantage of torque power – even as rpm speed falls
due to tough working conditions.
QSX15 400-600 hp (298-447 kW)
The QSX15 combines the best of all worlds, combining
low emissions and up to 5 percent better fuel economy.
The QSX15 is built to deliver clear advantages for any
need, with ratings at 400 to 600 hp (298-447 kW).
QSK19 800 hp (597 kW)
The QSK19 delivers the lowest life cycle cost with the
longest life-to-overhaul of any engine in its class. With
power output of 800 hp (597 kW), the durability of this
engine is well proven in the toughest duty cycles, making
it an ideal power source for high-output agricultural
equipment working under the most demanding
conditions.

Every Advantage.
Cummins provides a unique advantage to meet
EPA Tier 4 Interim and EU Stage IIIB low-emissions
regulations with a complete range of fully integrated
engine and exhaust aftertreatment solutions.
Cummins Compact Catalyst.
Our QSB3.3, QSB4.5 and QSB6.7 engines have
been designed to meet Tier 4 Interim emissions with
a totally passive Cummins Compact Catalyst that is
“fit and forget.” There’s no particulate filter. No
electronic controls or lamps. No regenerations.
Nothing. It is the only fully passive aftertreatment
system below 174 hp (130 kW).
Cummins Particulate Filter.
Cummins Particulate Filter is used on QSB6.7, QSL9,
QSX11.9 and QSX15 Tier 4 engines rated at 174
to 600 horsepower (130-447 kW). The Cummins
Particulate Filter is designed to replace conventional
mufflers in the exhaust system, reducing noise levels
as it ensures ultra-clean operation. Exhaust flows out
of the engine and into the Cummins Particulate Filter.
It passes through the Diesel Oxidation Catalyst (DOC)
and then into the Diesel Particulate Filter (DPF), where
Particulate Matter (PM) is collected on the walls of the
filter. The carbon is then oxidized to remove it from
the DPF. This cleaning process is called regeneration,
which can be passive or active.
Passive regeneration occurs when the equipment’s
duty cycle and exhaust temperature drive the
continuous oxidation of carbon, up to 99 percent of the
time, depending on application.
The Cummins Compact Catalyst is small, lightweight
and easy to fit onto space-constrained equipment. It is
available as a separate unit or as an integrated catalyst
and muffler. Multiple inlet/outlet options (including sidein
and side-out options) give engineers the flexibility
they need for specific equipment installations.
