The QSM Quantum System provides superior fuel economy with strong engine performance, engine protection and other programmable features. Components include:
QSM for Agriculture (Tier 3)
The QSM not only meets Tier 3 and Stage IIIA emissions standards, it uses in-cylinder technology, a simple and cost-effective solution that maintains the proven performance, dependability and durability of the QSM while operating cleanly and efficiently.
Every day, QSM engines are put to the test in farm machinery worldwide. With superior performance that's the result of advanced in-cylinder combustion technology and our responsive wastegated turbo. Both emissions and efficiency are optimized by the QSM's electronically controlled unit injectors, with cam-driven rate shaping.
In addition to providing exceptional reliability and durability, the advanced design of the QSM ensures that maintenance is kept to an absolute minimum. With oil change intervals that are double the previous standards in some applications and an auto-tensioning belt drive.
Available in a range of ratings from 290-400 hp (216-298 kW), the QSM was the first engine in the industry to be certified to EPA Tier 3 levels.
To ensure that every QSM 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 QSM comes with virtually every feature standard. Plus, an optional REPTO (Rear Engine Power Take-Off) adds capacity for driving remote-mounted devices.
Every QSM engine is covered by Cummins three-step warranty, one of the most comprehensive and simplest plans in the industry.
Features & Benefits
- Wastegated Turbo - Designed for optimum boost, it improves throttle response across operating range
- The Venturi™ Oil Filter and Lube System - 10-micron LF9001 filter from Fleetguard combines with a new lubrication system. Can double oil change intervals - up to 700 hours in some applications
- CELECT™ Electronic Engine Management - Provides superior performance, fuel efficiency, diagnostics and prognostics using full-authority electronics. Its programmable features let you customize engine performance to equipment use
- High-Capacity ECM - New space-efficient Electronic Control Module packs ten times more memory and ten times more processing power
- Sealed Sensors - Fully sealed to resist water intrusion. Combined temperature and pressure sensors reduce inventory and simplify maintenance with increased reliability
- Advanced Combustion Technology - Optimized injector tips and a reshaped steel piston bowl improve fuel economy and emissions control with longer oil change intervals
- Articulated Pistons and Liners - Steel-topped pistons handle higher cylinder temperatures for improved fuel efficiency and emissions control. Patented mid-stop cylinder liners resist cavitation and extend life-to-overhaul
- The Auto-Tensioning Belt Drive - Self-adjusting for optimum tension, which increases fan, alternator and fan belt life
- Improved Camshaft Durability - Exhaust valve lobes are designed to improve wear tolerance. The injector lobe profile has been revised to optimize injection
