Optimal performance at varying load demands.
The QSX15 incorporates Cummins proven technology enablers to meet EPA Tier 4 Interim and EU Stage IIIA low emissions standards.
The QSX15 achieves these very low emission levels by using our proven cooled Exhaust Gas Recirculation (EGR) and Cummins Particulate Filter. Both systems have been specifically developed for industrial applications delivering premium performance and durability you can depend on.
The Tier 4 Interim and Stage IIIA 15-liter engine incorporates Cummins Xtra-High Pressure Injection (XPI) fuel system enabling very high fuel injection pressure, providing cleaner combustion and improved engine response. Together, the fuel system and Cummins Variable Geometry Turbo (VGT™) provide optimal performance at varying load demands.
Additional performance-enhancing features include Cummins Direct Flow air filtration system providing a 35 percent smaller installation profile than radial air filters, plus improved filtration efficiency and a crankcase ventilation system with a highly-efficient coalescing filter. Cummins Electronic Control Module manages all components for a completely integrated system.
All backed by the best customer support in the business.
Cummins Extra High Pressure Injection (XPI) Fuel System– Most capable common-rail fuel system utilized on a heavy-duty engine, enabling faster, smoother power delivery with lower fuel consumption.
Diesel Particulate Filter (DPF)- A state of the art, efficient exhaust diesel particulates filter that reduces particulate matter by over 90%. (Only available on QSX15-G14 and QSX15-G15 Tier 4i/EU Stage IIIA G-Drive engines.)
Turbocharger System– A new electronic variable geometry turbocharger (VGT) is used, which is able to continuously vary airflow boost and manage the EGR.
Exhaust Gas Recirculation (EGR) System– Proven cooled EGR system that reduces nitrogen oxide (NOx) emissions.
Crankcase Breaker– Utilizes a “dripless” crankcase breather system.
Direct Flow Air Filter– Provides 35 percent smaller installation than typical engine air filters while retaining the same filtration efficiency.
Electronic Control System– Provides faster processing power and increased memory capability while allowing seamless electronic interface to other systems.
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 interim emission requirements.
