“Helping our customers to succeed is our driving force,†said Brett Merritt, vice president and head of road engine business at Cummins. “Cummins is deeply involved in the multi-application of Power Technology to provide our customers with the most suitable applications for the most suitable time. Good solutions to help them succeed." Advanced diesel engine platform In the coming decades, diesel power technology will continue to be the best power solution in many markets. For 2020, Cummins further expanded its advanced diesel power platform. At the show, Cummins' heavy-duty flagship product, the 2020 X15 Energy Series engine, the 2020 X15 Productivity Series, and the X15 Performance Series (X15 Performance Series) The X12 engine has become a highlight of the show and has received much attention. The 2020 version of the X15 energy-saving series engine, focusing on the customer's full life cycle cost, optimizes and improves the engine's basic hardware and intake handling system, and improves fuel economy by 3.5% compared to the 2017 version. At the same time, the X15 platform has a fuel change cycle of 120,000 km (75,000 miles) and can be extended to 160,000 km (100,000 miles) by participating in the Cummins Oil GuardTM program, increasing vehicle attendance and reducing total operating cycle costs. . In addition, the 2020 version of the X15 energy-saving series engine and the Eaton gearbox drive system enhances powertrain performance and increases fuel economy by optimizing engine base hardware and air handling systems. effectiveness. In addition to the original ADEPT smart assisted driving technology, the new series also uses new technologies such as predictable shifting, predictable braking, ramp acceleration and dynamic power to improve the team's powertrain performance and driving experience. The new 2020 version of the X15 high-efficiency series engine features a wider range of engine speeds and is designed for multi-purpose, special-purpose, heavy-duty applications to meet the stringent requirements of the engine for powerful power, fast response and high performance. . The X15 Performance Edition engine has not changed much in the original version that has earned the customer's trust, retaining excellent transient response and powerful engine braking. The X12 engine, with the lightest quality in its class, provides the ideal solution for weight-sensitive customers in the long-haul transportation sector. The 12L engine is paired with the Eaton Cummins Endurant gearbox to provide the industry's lightest powertrain and long service intervals. In addition, as part of the investment in diesel power core technology, Cummins is conducting research to further improve turbocharger efficiency and reduce engine system emissions. To help customers better cope with the challenges of carbon dioxide and NOx emissions in the future, Cummins is developing a new integrated system that combines the air handling system with the post-processing architecture to help the turbocharger work efficiently while efficiently performing heat. management. Cummins Digital Solutions In the field of digital intelligent services, Cummins actively explores continuous innovation. Today, Cummins Connected SolutionsTM, built on an open digital platform, enables data connectivity across multiple environments, providing remote monitoring, reporting, calibration and repair service solutions to help customers better manage fleets and cost savings. Customer experience throughout the product lifecycle. In the near future, fault prediction technology will help customers identify and diagnose problems early, and deploy parts to prioritize procurement to optimize the service experience. In addition, Cummins plans to further enhance remote service functions and optimize powertrain management to improve fuel efficiency, guide drivers and manage vehicle speed. Electric power solution Following the official launch of the electric power business in 2017, the pure electric heavy-duty (7-level) concept truck AEOS was launched. In just two years, Cummins continued to break through in the field of electric power. At present, Cummins electric powertrain has been widely used in buses, school buses, light commercial vehicles and medium-sized vehicles. Six of the world's seven applications have introduced complete electric powertrain solutions. At the show, Cummins also introduced its latest integrated electric drive system. The new electric drive system integrates the motor, transmission and inverter. Currently, the new traction system is in the development stage and is expected to be launched in the second half of 2022. Compared to direct drive systems, the new system will reduce weight and volume by 1/3 and increase efficiency by 10%, which will greatly simplify the installation of OEM customers and expand to medium and heavy commercial vehicles. New breakthrough in hydrogen fuel cell technology As early as more than 20 years ago, Cummins has focused on the development of hydrogen fuel cell technology. Recently, Cummins' several important initiatives in the field of hydrogen fuel cells, including the acquisition of Shui Ji Neng, signed a memorandum of cooperation with Hyundai Motor Co., to develop hydrogen fuel cell technology in the commercial market in North America, and to invest in hydrogen fuel cell range extender providers. Loop Energy, etc., further promotes Cummins' ability to innovate and expand hydrogen fuel cell technology. With a complete industrial capability from hydrogen production technology to hydrogen fuel cell manufacturing, Cummins offers users a complete and unique hydrogen fuel cell solution that seamlessly links customers' needs. At this year's North American Commercial Vehicle Show, Cummins made another breakthrough in hydrogen fuel cell technology – the first electric power heavy-duty truck with hydrogen fuel cell, which was highly anticipated! The show car is a zero-emission, North American 8-grade 6x4 heavy-duty tractor that can be widely used in special-purpose vehicles, inter-provincial transportation, inter-city distribution, port haulage and container transportation. To enable all OEM (OEM) customers and end users to benefit from Cummins fuel cell power, Cummins has not developed with any of the OEM's partners, which are designed and manufactured at Cummins equipment at US headquarters. The Integration Center (CMIC) is complete. The truck is equipped with a proton exchange membrane fuel cell (PEM) developed by Shui Ji Neng, the newest member of the Cummins family. It is designed to be 90 kW and can be expanded to 180 kW in 30 kW or 45 kW increments. It is also equipped with 100 kWh of lithium ion. battery. It has a cruising range of up to 400 km (250 miles) and can be extended by adding additional hydrogen tanks, increasing hydrogen tank pressure or installing additional fuel cells. In addition, in addition to the integration of third-party supplier parts, many of the car's key powertrain components, including proton exchange membrane fuel cells, system controllers, powertrain controllers, wiring harnesses and distribution boxes, were developed by Cummins. . “Cummins is proud to have the technology to power the future. From advanced diesel power technology to pure electric, to the first hydrogen-fueled trucks today, we are committed to innovative power solutions. Customers.†Brett Merritt, vice president and head of the road engine business at Cummins, said, “After a hundred years, we are committed to the next century with unwavering commitment to provide our customers with a reliable and innovative product portfolio.†Ultra-Precision Live Center, Ultra-precision High Speed Live Center, machine tool parts in machining.
