Cummins is currently expanding its product portfolio to include alternative fuels, small engines and electrification, but diesel engines remain its core business. Cummins' continued investment in diesel technology research and development is paying off, and the Cummins team is focused on developing clean emissions technologies that allow companies to meet increasingly stringent emissions regulations. Cummins demonstrated a revolutionary concept of integrated turbocharging and aftertreatment systems. This revolutionary concept consists of a fixed-rotor turbocharger (RTC) fixed-section turbocharger and a tightly coupled SCR catalyst, representing a future blueprint for clean power technology. “This is an exciting time for the power industry. Customers tend to choose more efficient, more reliable and more flexible power solutions,†said Tracy Embree, President of Cummins Parts Business Unit. “As engine manufacturers are The new power solutions are innovating, and we realize that the systems and innovations of the new ideas are changing the industry. We are very proud to be at the forefront of development." Embeen also said, “At Cummins, we respond to market shifts by expanding our product portfolio to meet future demands. To meet the most stringent environmental regulations, we have adopted innovative engine technology to meet the most advanced emission regulations, thus enabling Diesel engines are cleaner, simpler and more efficient. We will be releasing new technologies at the Hannover Commercial Vehicles Show in Germany, believing that the value of innovative engine technology will be proven again in next-generation applications." From an innovation perspective, current research and development for integrated systems is focused on optimizing thermal management and improving fuel economy. Accordingly, we focus on helping our customers reduce costs while improving engine performance. The integrated RTC transports the exhaust gases to the turbine and injects urea into the tightly coupled catalyst via Cummins' latest UL4 urea nozzle. This timely conversion enables the gas to reach the SCR at a temperature 70 ° C higher than the conventional SCR. Turbocharged combined with a single-cylinder post-processing unit (Single Module) for 97% conversion. This integrated system will meet future lower NOx and greenhouse gas limits, as well as the benefits of reduced emissions in cold start and urban conditions. The new concept system is demonstrating Cummins' continued investment and ongoing efforts to meet future emissions regulations. To commemorate the 20th anniversary of the development of the Variable Section Turbocharger (VGT), Cummins Turbo technology also previews the most advanced seventh-generation variable-section turbocharger. Compared to the previous generation, the seventh-generation variable-section turbocharger saves customer fuel and achieves greater turbine efficiency through patented nozzle and cover design, making it the most efficient turbocharger available today. Cummins' business also emphasizes investments in regulations from 2021-2024 and beyond, which are focused on pulse optimization, intake valves, oil seals and motorized turbochargers. In addition to the integrated system and the seventh-generation variable-section turbocharger, Cummins will also showcase a range of other components at the Hannover Commercial Vehicles Show in Germany, demonstrating the Cummins engineering team's requirements for the next 10 years. Forward-looking research and development and technology accumulation.
In the die casting industry, according to the difference of equipment, it can usually be divided into cold chamber die casting and Hot Chamber Die Casting. Cold chamber die casting is most used in aluminum alloy die casting. Cold chamber die casting is suitable for die casting of various non-ferrous metals, and its models are relatively complete, and the die castings of large and small parts are more suitable for production; the production operation is relatively simple, the production efficiency is high, and it is easy to automate. At present, the most used in the industry is also cold chamber die casting.
SCZY provides one-stop services such as mold development, die-casting production, product follow-up CNC machining, and product surface treatment. We have our own precision mold workshop, die-casting production workshop, and follow-up precision CNC workshop, which can ensure delivery and quality at the same time. It also provides outsourced surface treatment services, so that customers can have no worries.
