Cummins is showcasing a diverse set of new technologies aimed at reducing total cost of ownership for OEM customers at the IAA Commercial Vehicles Show in Hannover, Germany.

The technologies being unveiled by Cummins include turbocharger components designed for high efficiency and a tailored mid-range fuel system that combined can offer up to 7-8% fuel efficiency improvements. Cummins is also demonstrating a new aftertreatment solution with the unveiling of the new higher performance Compact Box and display of the Single Module that offers a 60% reduction in space claim, and 40% reduction in weight, providing improvements for customer integration and installation.

Cummins Turbo Technologies will unveil specific turbocharger component design to help achieve up to 8% turbocharger efficiency gains and improve overall fuel economy.

The Mixed Flow Turbine Wheel enables turbine efficiency improvements of 2-3% and lower inertia resulting in improved transient response and fuel economy at key engine operating points. A Wastegate Blown Diffuser improves turbine stage efficiency by up to 5% resulting in increased fuel economy and reduced CO2. The Twin Port option on electric wastegates can increase stage flow by up to 45% allowing engine downsizing without a loss in power, as well as optimizing aftertreatment.

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 Heavy Duty XPI Fuel System.

This specialty tailored system also delivers better engine performance and improved fuel economy to mid-range engines. The system can provide up to 5% fuel efficiency improvements by optimizing injector specification based on the duty cycle and selecting the right pump size at engine integration level.

Launching in 2017, Cummins Emission Solutions is addressing global customer needs for improved efficiency for heavy-duty cabover truck applications with the development of a new compact box. The new box is 20% smaller than the most compact Euro VI HD box system currently on the market and a redesigned aftertreatment solution offers simplified vehicle integration to reduce installation costs and potentially improved fuel economy. The new Compact Box achieves higher NOx conversion rates when compared to the current modular aftertreatments in the market.

Another aftertreatment 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% lighter than current modular aftertreatment systems and offers improved reduction of particulate matter and NOx capabilities. The reduced size and weight, as well as various length options available, means customers can select the right aftertreatment system sized appropriately for their engine output needs.

Cummins Turbo Technologies will also be showcasing its compressor oil seal technology which improves resistance to oil leakage by 200%, according to the company. This provides a more robust turbocharger design, even at lower engine speeds to meet customer requirements for downspeeding.

Cummins Filtration’s Next Generation EnviroGuard rotating Crankcase Ventilation solution is ultra-efficient and designed to meet the needs of OEMs facing strict emissions regulations while protecting the engine and extending CV service life. Depending on how the product is applied, the product can last between 4 – 8 times longer than conventional designs and requires minimal redesign for OEMs to adopt the technology.

 “Customers demand ever higher levels of efficiency and durability from their commercial vehicles to optimize business costs and address the global challenge of meeting environmental standards,” said Tracy Embree, president Cummins Components. “We have carefully considered these demands to develop technologies that empower our customers with solutions that deliver greater fuel economy, engine efficiency, extended service intervals, reduced downtime due to improved durability, and improved emissions compliance.”
