The EcoFit single module is a potential solution designed to meet Stage V requirements in a small, light-weight, simple and robust advanced aftertreatment system package.
Cummins revealed a selection of next generation innovations at Intermat 2015, showcasing the full spectrum of its expertise in component technologies for the commercial diesel engine.
Cummins Turbo Technologies, a global engineering leader in turbocharger technology, unveiled its next generation Holset VGT, designed to improve turbo efficiencies and deliver greater fuel economy. This latest innovation in VGT technology offers multiple benefits, such as enhanced integration with the engine system due to a new actuator, improved durability, and optimized performance through the moving-shroud variable geometry mechanism. The next generation series 300 variable geometry turbocharger is capable of improving turbo efficiencies by up to 12 percent at low engine speed as well as delivering reduced carbon dioxide (CO2) emissions. In addition, this latest solution is 10 percent lighter than its existing counterpart, creating greater fuel economy, according to the manufacturer.
Cummins Emission Solutions, a global leader in aftertreatment technologies, introduced the first of its next generation of aftertreatment platforms for future emissions regulations — the EcoFit single module. This platform product is a potential solution designed to meet Stage V requirements in a small, light-weight, simple and robust advanced aftertreatment system package.
The EcoFit single module, designed for heavy-duty and midrange engine applications, is up to 60 percent smaller and 40 percent lighter compared to today’s combined selective catalytic reduction (SCR) and diesel particulate filter (DPF) systems while achieving advanced emissions reductions levels. The system enables easier equipment integration for OEM customers, and its lower weight minimizes the impact on equipment weight, which will contribute towards improving fuel economy, according to the manufacturer.
Advancements in catalyst technologies are enabling efficiency improvements throughout the entire system, and Cummins Emissions Solutions has invested in DPF technologies with higher ash capacities, allowing for more time between cleaning intervals for its customers. The SCR catalysts, coupled with the EcoFit UL2 liquid-only urea dosing system, offer enhanced oxides of nitrogen (NOx) reduction, and, linked with improved thermal management capability, deliver the optimum solution for emissions reduction and minimized fuel and diesel exhaust fluid (DEF) usage.
Suzanne Wells, executive director — sales and marketing, components business, said “These next generation component technologies deliver a number of technical advances, to satisfy market and customer demands. Over the last few years, we have seen continued demand for smaller, lighter, high-quality components to drive diesel engine efficiency improvements, as well as the industry requirement from manufacturers for equal and higher power outputs.
“The latest technological enhancements enable us to meet these demands, as well as offer greater versatility, which allows the development of tailored customer solutions.”
