As a world-leading supplier of diversified power solutions, since the first engine came out in 1919, Cummins' main business has never deviated from the core of power solutions. During this period, generations of Cummins engines have pushed the historical wheels of the automobile industry forward.
Among them, the release of Cummins 15-liter China stage VI engine has led an innovative breakthrough in the industry. Relying on the two "trump card" of thermal efficiency and maximum power, this product has promoted the road logistics industry to enter a "new era" in terms of power, TCO (total life cycle cost) and customization.
Xi'an Cummins 15-liter engine:
15N Natural Gas Engine:fuel nataural gas,displacement 14.5L; Power 430-550ps, 6 cyliners in line,turbochared intercooler.
M15 Diesel Engine:fuel diesel,displacement 14.5L; Power 530-680ps, 6 cyliners in line,turbochared air-air cooler.
In terms of power, the Cummins 15-liter China Stage VI engine has a power of 680 horsepower (about 500kW) and a torque output of 3200N m, with a maximum braking power of 612 horsepower (about 450kW), and a power of 47 horsepower (about 34.5kW), the acceleration performance is increased by 16%, and the climbing performance is increased by 20%, which meets the needs of the trunk medium and long-distance logistics market for high transport timeliness and creates a "new era of high-efficiency power".
In terms of TCO, the Cummins 15-liter China stage VI engine breaks through the problem of thermal efficiency, and the fuel economy can be increased by 5-12%. The Down-Speed performance of the power chain is further optimized to achieve lower fuel consumption at the same speed and faster speed at the same fuel consumption. . Coupled with the longest oil change interval of 150,000 kilometers, 1 ton dead weight, and the application of Cummins National Six Power's "Smart Brain 2.0" and industry-leading high-horsepower compression braking, it has created a "New Era of TCO".
In terms of customization, the Cummins 15-liter China stage VI engine is customized in the development stage according to the product positioning of different vehicle manufacturers. While ensuring the overall performance, it can play a differentiated advantage; The remote calibration upgrade optimizes the engine settings to be more in line with actual working conditions; according to the needs of different customers, it customizes services and data tools to improve service efficiency and user experience, creating a "new era of customization".
At present, the global road logistics industry is tending to choose high-efficiency power with high horsepower and low fuel consumption. The 15-liter engine has become the mainstream configuration for trunk logistics in the international long-distance market. In China, the choice of medium and long-distance logistics power also shows a significant trend of upgrading the engine displacement from 13 liters. Cummins is the first to launch the 15-liter China VI engine, which just meets the new demand for this power segment in the domestic commercial vehicle market.
Technological innovation drives optimization and upgrading
The 15-liter China stage VI engine is an efficient transportation power created by Cummins for China's logistics industry and tailored to create an "epoch-making era". In terms of technological innovation, this engine has achieved innovative upgrades in terms of design concept, material selection and digital technology application.
Specifically, the Cummins 15-liter China stage VI engine adopts a newly designed high-compression ratio piston bowl, high-efficiency supercharger, large-flow fuel injector, low back pressure after-treatment and combustion management system, which not only meets China VI-b emission standards, And the fuel economy has been further improved.
In terms of technology and process, this engine adopts a new optimized design of flow channel and impeller profile, and the overall efficiency is increased by 3%. With the unique pressure maintaining technology, ultra-high pressure injection, and full-range closed-loop oil supply compensation, fuel economy is significantly improved. and torque transient response.
At the same time, the Cummins 15-liter China stage VI engine adopts a newly designed U-shaped low back pressure after-treatment structure, which saves installation space, saves fuel and is easy to maintain and repair; the advanced urea mixer achieves extremely low back pressure and improves fuel economy and reduce the crystallization of urea, so that the urea can achieve ideal atomization and mixing effects, and the high-efficiency copper-based SCR can achieve higher NOX conversion efficiency.
In addition, the non-EGR design of Cummins 15-liter China stage VI engine and advanced intelligent thermal management technology can achieve better fuel adaptability; "Smart Brain 2.0" (full closed-loop intelligent control) ensures the optimal integration of engine and aftertreatment, and achieves an optimal balance of economy, power and environmental protection; Provide means to intelligently manage the production differences of subsystem parts and realize the system control optimization of individual vehicles; The industry's top NanoNetTM modular nano fuel fine filter and oil filter, combined with China VI engine special oil, achieve an ultra-long oil change interval of 150,000 kilometers, efficiently protect the engine, and reduce maintenance and fuel costs; Intelligent digital products (remote health check, remote calibration upgrade, intelligent diagnosis system) are further escorted.
Cummins 15-liter China stage VI engine has been installed on China domestic first-line brand heavy-duty truck models such as Dongfeng, Foton Daimler, Shaanxi Automobile, etc., and is favored by China's long-distance trunk line, LTL express and other logistics market segments, and has become an important power for efficient operation of logistics fleets, energy conservation and carbon reduction.
