Overview Agriculture Construction

Overview:

The QSL uses Cummins advanced in-cylinder technology to meet Tier 3 and Stage IIIA emissions standards. This is a simple and cost-effective solution that maintains the proven performance, dependability and durability of the QSL while operating cleanly and efficiently.

There is no substitute for power when your equipment needs it. Every hour of every day, Cummins QSL engines deliver performance that meets the challenge of tough agricultural applications worldwide. With ratings from 280-365 hp (209-272 kW) and a torque rise of up to 50%, QSL engines combine advanced in-cylinder combustion technology and a High Pressure Common Rail (HPCR) fuel system that increases power and reduces emissions. At the same time, the QSL delivers better cold starting and runs 50% quieter for increased operator comfort. Every day.

In addition to providing exceptional reliability and durability, the advanced design of the QSL ensures that maintenance is kept to an absolute minimum.

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

The QSL comes with virtually every feature standard. Options include REPTO (Rear Engine Power Take-Off) and a 12- or 24-volt electrical capacity.

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

The in-cylinder combustion technology, high-pressure injection system and electronic controls of the QSL not only ensures clean operation that meets Tier 3 emissions standards, but also ensures powerful and efficient operation every time. Cummins QSL engines are built to deliver heavy-duty performance in every piece of machinery. Full-authority electronic engine controls combine with the High Pressure Common Rail (HPCR) fuel system for strong performance at every rpm. Its free-breathing 24-valve design and centered injectors give the QSL one of the highest power-to-weight ratios in its class. Plus, the QSL is capable of running on high-sulfur fuels, so it's at home in every corner of the globe.

Its ECM (Electronic Control Module) is totally programmable, so you can specify performance parameters to match a wide range of operating conditions and load factors. For every job.

Standard features on the QSL include:

Full-Authority Electronic Controls - Provide seamless integration with other components to optimize engine operation
Stiffer Block and Head - For reduced noise and vibration. Fluid circuits are integrated, replacing hoses and eliminating potential leaks
High Pressure Common Rail Fuel System - Allows multiple injection events for cleaner, quieter operation with consistent performance at every rpm. Also improves cold-weather starting
Wastegated Turbocharger - Delivers maximum power and torque
Mid-Stop Cylinder Liners - Reduce cavitation and improve rebuildability
Gear Housing Design and Front-End Support - The gear housing and accessories mount directly to the block for improved durability
Improved Piston Design - Symmetrical piston bowl combines with centered injectors to deliver optimal combustion
Heavy-Duty Lube System - Targeted piston cooling and increased lube flow to the power cylinder result in increased piston reliability and durability. Improved lube and bypass filtration system increase ring and bearing life by as much as 63%
Improved Crankcase Ventilation - Virtually eliminates oil carryover

Maintenance Intervals

Features have been designed into every QSL engine that minimize downtime for maintenance. The two-stage dual fuel filter provides a balanced level of particle separation to maximize fuel filter life and protect the vital fuel system components. An integrated water pump, lube pump and cooler housings and coolant bypass eliminate possible leak points. QSL engines are designed to run up to 500 hours between scheduled fuel and oil filter changes.
