Cummins will showcase a diverse set of new technologies to tackle the challenge of reducing total cost of ownership for OEM customers at the upcoming IAA Commercial Vehicles Show in Hannover this September.
The technologies address global challenges for engine systems and allows Cummins’ expertise to deliver integrated solutions for air handling, fuel and after treatment systems.
The technologies being unveiled include turbocharger components designed for high efficiency and a tailored mid-range fuel system that combined can offer up to 7-8 percent fuel efficiency improvements. Cummins’ expertise in after treatment solutions is also demonstrated with the unveiling of the new high performance Compact Box and display of the Single Module that offers a 60 percent reduction in space claim, and 40 percent reduction in weight, providing significant improvements for customer integration and installation.
“Cummins supplies a range of technologies to customers in every region of the world and we have carefully considered the operational challenges faced by each customer to develop a robust set of technological solutions that deliver significant benefits,” said Tracy Embree, President Cummins Components. “With our expertise demonstrated across the critical engine components, Cummins is in the unique position to offer integrated technologies to provide system solutions that meet ever higher demands for efficiency and durability in order to fully optimize performance.”
Focus on Fuel Efficiency
Cummins has seen a shift in industry focus from emission driven regulations to an increased focus on fuel economy. In response to this Cummins Turbo Technologies will unveil specific turbocharger component design to help achieve up to 8% turbocharger efficiency gains and improve overall fuel economy.
- Mixed Flow Turbine Wheel enables turbine efficiency improvements of 2-3 percent
and lower inertia resulting in improved transient response and fuel economy at key engine operating points. - Waste gate Blown Diffuser improves turbine stage efficiency by up to 5 percent resulting in increased fuel economy and reduced CO2.
- The Twin Port option on electric waste gates can increase stage flow by up to 45 percent allowing engine downsizing without a loss in power, as well as optimizing after treatment.
Cummins Fuel Systems have expanded their product range with the development of a mid-range fuel system to be launched in 2017. The products offer global customers industry-leading injection pressure as demonstrated on the dependable Heavy Duty XPI Fuel System. This specialty tailored system also delivers optimal engine performance and improved fuel economy to mid-range engines. The system can provide up to 5 percent fuel efficiency improvements by optimizing injector specification based on the duty cycle and selecting the right pump size at engine integration level.
Emissions Solutions Simplified
Launching in 2017, Cummins Emission Solutions is addressing customer needs for improved efficiency for HD cab over truck applications with the development of a new compact box; 20 percent smaller than the most compact Euro VI HD box system currently on the market, the redesigned after treatment solution offers simplified vehicle integration to reduce installation costs and potential improved fuel economy. The new high performance Compact Box achieves higher NOx conversion rates when compared to the current modular after treatments in the market.
Another after treatment solution helping to meet customers’ space claim challenges is the Single Module which will also be displayed at IAA. The single cylinder system is up to 60% smaller and 40 percent lighter than current modular after treatment systems and offers improved reduction of particulate matter (PM) and oxides of nitrogen (NOx) capabilities. The reduced size and weight, as well as various length options available, means customers can select the right after treatment system sized appropriately for their engine output needs.
