Construction Tier 3/Stage IIIA.
No matter what type of application you may have and no matter where on the globe it may be, the Cummins Tier 3/Stage IIIA certified engines are the choice you can depend on. Every time. Cummins uses in-cylinder technology, a simple and cost-effective solution that maintains Cummins proven performance, dependability and durability while meeting Tier 3 and Stage IIIA emissions standards, and providing the base platform to reach Tier 4 requirements as well.
Cummins has so much confidence in the reliability of our Stage IIIA engines - and the rapid response capability of our service network - we offer an Uptime Guarantee on equipment purchased, registered and operated in EU countries from May 1, 2007 through April 30, 2008. If your engine is out of service and it can't be repaired within 48 hours from fault diagnosis, you will receive a parts and service credit equivalent to 500 Euros on the future purchase of Cummins parts or service. See the European Stage IIIA Uptime Guarantee for registration requirements and terms.

QSM
Every day QSM engines are put to the test in industrial applications worldwide. With superior performance that's the result of advanced in-cylinder combustion technology and our responsive wastegated turbo. Advanced design ensures that maintenance is kept to an absolute minimum. Ratings from 290-400 hp (216-298 kW).
QSL
Every hour of every day Cummins QSL engines deliver performance that meets the challenge of a multitude of tough industrial 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.
QSC
Cummins QSC engines are built on one of the world's most successful - and durable - engine block designs. In fact, there are over three quarters of a million in use around the globe every day. Ratings are from 215-305 hp (160-228 kW). And there's no fuel economy penalty when compared to Tier 2 mechanical engines.
QSB6.7
Our new QSB6.7 diesel engine makes short work of the tough jobs. At 6.7 liters, it has 13% more displacement with more torque and horsepower. Advanced electronic controls and a HPCR fuels system capable of multiple injection events per cycle keep it running quietly and efficiently. Ratings range from 130-275 hp (97-205 kW).
QSB4.5
Cummins QSB4.5, a 4.5-liter power plant incorporates similar technology and user benefits to the 6.7-liter model. Electronic controls are easily customized using Cummins PowerMatch. The QSB4.5 is rated from 110-160 hp (82-120 kW).
QSB3.3
Cummins QSB3.3 combines the proven reliability of our 3.3-liter platform with electronics and a High
Pressure Common Rail (HPCR) fuel system. The result is an engine capable of 110 hp (82 kW) in a
package that takes 30% less space and weight than the average 4.0- to 4.5-liter engine. It meets Tier 3/Stage
IIIA emissions without exhaust gas recirculation, operates safely on fuel with a high sulfur content, and it
runs quieter and smoother with durability that's equal to any competitive engine. Ratings range from 80-110 hp (60-82 kW).
A Series
Every one of the A Series engine ratings under 48 hp is compliant with Tier 4 which means no change to the engine through 2012. We also meet Stage IIIA regulations through 2017. Our 2300T is certified to Tier 3/Stage IIIA regulations. Ratings range from 31-68 hp (23-45 kW).
