Cummins QSC
 Cummins Southern Plains, Ltd. |
These engines combine the proven Quantum System, full-authority electronic controls with the reliable performance you’ve come to expect from Cummins engines.
QSC Engine Applications
• Agricultural
• Construction
Key Features
•
Superior Performance. The QSC's improved performance is gained through its use of superior diesel engine technology.
•
Low Maintenance Costs. Greater reliability with fewer parts.
•
Better Coverage. One of the simplest and most comprehensive coverage plans anywhere.
Performance
• The QSC has applied the same Quantum technology for the 4-cylinder versions of this engine.
•
Full-Authority Electronic Controls offer advanced diagnostics and programming options. The Electronic Control Module is totally programmable, so you can specify performance parameters to exactly match your equipment. It’s a concept we call PowerMatch. Then, we optimize the engine’s performance with other vehicle components, using the Cummins
Advisor program.
•
Cummins Advisor software builds a virtual model to show how the QSC engine is installed in your equipment then makes sure that all systems work as a team for optimum performance.
•
Electronic Fuel Injection combines high injection pressures with electronically controlled timing and fueling for precise and instantaneous control.
•
Parent Bore Cylinder Block is designed for reduced noise and increased durability. Integrated design features eliminate potential leak points.
•
Wastegated Turbochargers are custom-designed by Holset for high-speed ratings. Wastegates provide for better low engine speed performance and high engine speed boost.
•
Ni-Resist piston inserts give exceptional oil control.
•
Mid-stop cylinder liners reduce cavitation and improve rebuildability.
•
Plasma-coated top ring increases durability in high-horsepower ratings.
• 20% more
low-end torque means greater pulling power in the field.
• The
Low Tension Belt Arrangement has a simplified design for maximum power output through the accessory drive, with the ability to handle larger hydraulic pumps.
• A
24-Valve Cylinder Head at four valves per cylinder provides increased power with faster response across the power band. Vertical injectors are centered over the piston for improved combustion and low-end torque. Single-piece head has integrated intake manifold and fuel supply.
• The Patented Cummins
fuel system delivers high injection pressures, independent of engine speeds. The result is improved throttle response, low-end torque and fuel economy with reduced emissions.
• The QSC has up to
50% less noise.
•
The bearings have a large surface area to
handle higher loads with greater durability.
• The
exhaust manifold allows for heat expansion and contraction, eliminating metal stress fractures.
•
Reduced friction in the power cylinder means longer life and increased power output.
• The QSC is available with a front-mount accessory drive or Rear Engine Power Take-Off (REPTO).
Emission Standards
• Tier 2/Stage 2 Certified
• Maintains the lowest possible cost of installation.
Easy Maintenance
The Cummins QSC engine has numerous options that make equipment integration easier.
• The QSC has been designed to run up to 500 hours between scheduled maintenance stops. Long maintenance intervals combined with a simplified design means
lower operating costs.
•
Low-Maintenance Fuel Filter Assembly - Integrated water separator and water-in-fuel sensor help prevent performance
problems that result from contaminated fuel. A 10-micron filter is designed for filter change intervals of 500 hours – consistent
with oil change intervals.
