Overview:

The QSB Series incorporates Cummins proven technology enablers to meet EPA Tier 4 and EU Stage IIIA low emissions standards.

The QSB Series achieves these very low emission standards by using our proven cooled Exhaust Gas Recirculation (EGR) and aftertreatment systems.  Both systems have been specifically developed for industrial applications delivering premium performance and durability you can depend on.

Additional performance-enhancing features include a high pressure common rail fuel system for greater fuel efficiency, lower noise and reduced emissions.  Cummins Direct Flow air filtration system providing a 35 percent smaller installation profile than radial air filters, plus improved filtration efficiency.  The engine also incorporates a crankcase ventilation system with a highly-efficient coalescing filter for cleaner engine operating conditions.  Cummins combines full-authority Quantum System electronic controls, managing all components for a completely integrated system with the impressive reliability and durability and long maintenance intervals you expect from the industrys Tier 4 technology leader.

All backed by the best customer support in the business.

Low Exhaust Emissions  The latest generation of Tier 4 Final certified engines reduce emissions through efficient fuel combustion, reducing most of the emissions at source. The Selective Catalytic Reduction (SCR) further reduces pollutants to meet Tier4 Final standards. Our Tier 4 Interim QSB7 utilizes Diesel Particulate Filter

Direct Flow Air Filter  Provides 35% smaller installation than typical engine air filters while retaining the same filtration efficiency.

Full-Authority Electronic Controls Optimize engine operation and deliver critical information for controlling costs, reducing maintenance and seamless integration with other components.

Low-Maintenance Fuel Filter Assembly The fuel filter incorporates an integral water separator and water-in-fuel sensor; 500-hour filter life with easy top-load replacement using standard Fleetguard filters.

Integrated Design Each component (Engine, Aftertreatment and Air Cleaner) has been has been specifically developed and rigorously tested for G-Drive products, ensuring high performance, durability and reliability.

Service and Support G-Drive products are backed by an uncompromising level of technical support and after sales service, delivered through a world class service network.

To protect public health and conserve our planet's natural resources, legislation from the U.S. Environmental Protection Agency (EPA) and regulatory agencies in the European Union (EU) has, for the past decade, required that pollutants produced by diesel engines - such as nitrogen oxides (NOx), hydrocarbons (HC) and particulate matter (PM) - be reduced.

Throughout this time, Cummins Inc. has been at the forefront of the move to meet these new standards, becoming:

  • the first manufacturer to introduce EPA Tier-2 and Tier-3 products to the market - ahead of the regulatory deadline
  • the first manufacturer to introduce EU Stage IIIA compliant generator-drive diesel engines to Europe
  • the leader in innovative emissions solutions that focus on in-cylinder design improvements and advanced after-treatment solutions to eliminate most of the NOx, HC and PM to meet EU Stage IIIA and EPA Tier 4 emission requirements.

Cummins Power Generation provides the best warranty and extended warranty plan in the industry. You can expect Cummins Power Generation and its authorized warranty locations to:

  • Stand behind Cummins Power Generation products.
  • Repair all failures that are a result of defects in materials or factory workmanship by Cummins Power Generation, or arrange for OEM warranty service if component is from another manufacturer.
