Cummins is also showcasing its aftertreatment solutions expertise with a new Compact Box (pictured) and Single Module, offering a 60% space reduction and 40% weight reduction.
The turbocharger component design features a 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, while 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 optimising aftertreatment.
The new mid-range fuel system on show will be launched in 2017 and, says Cummins, offer industry-leading injection pressure as demonstrated on the Heavy Duty XPI Fuel System. This tailored system also delivers optimal engine performance and improved fuel economy to mid-range engines. The system can provide up to 5% fuel efficiency improvements by optimising injector specification based on the duty cycle and selecting the right pump size at engine integration level.
Also launching in 2017, Cummins Emission Solutions is meeting customer needs for improved efficiency for heavy-duty cab over truck applications with the development of a new Compact Box – 20% smaller than the most compact Euro 6 HD box systems currently on the market, the redesigned aftertreatment solution offers simplified vehicle integration to reduce installation costs and potential improved fuel economy.
The new high performance Compact Box also achieves higher NOx conversion rates when compared to the current modular aftertreatments in the market.
Also on display at IAA is Cummins’ new Single Module, a single cylinder system up to 60% smaller and 40% lighter than current modular aftertreatment systems and promising improved PM and NOx capabilities.
