On November 15, the 22nd China International Internal Combustion Engine and Parts Expo (referred to as the "Expo", or commonly known in the industry as the "International Internal Combustion Engine Exhibition") opened in Nanjing, Jiangsu Province. At the same time, Dongfeng Cummins organized the theme activity of "Creating 'Core' Drive, Leading the New Era of Internal Combustion".
Facing the new trend of commercial vehicle power, Dongfeng Cummins, as a leading brand in the industry, continues to carry out innovation and upgrading, and leads every upgrade in the engine industry.
Deep plowing in internal combustion engine, leading the industry in technology level
With years of deep plowing in the internal combustion engine industry, Dongfeng Cummins has profound manufacturing and R&D capabilities and a rich product matrix, and has brought a new generation of internal combustion engine solutions to the industry at this Expo. Dongfeng Cummins presented four heavyweight products at the exhibition, including the Dongfeng Cummins Z15N gas engine, which has been created by the century-old Cummins for 50 years in the field of natural gas, the newly-launched Legend 460/480 hp diesel engine this year, the ISDe4.5 diesel engine tailored for short- and medium-haul markets, and the Z14 with the integrated powertrain with the Eaton 12-speed AMT gearbox.
Shi Lei, Chief Product Engineer of Dongfeng Cummins, said on the spot: "Dongfeng Cummins is always committed to providing customers with efficient, reliable and environmentally friendly power solutions. In the face of the future trend of intelligent, efficient and environmentally friendly internal combustion engines, Dongfeng Cummins has launched the National VIb power product platform covering the whole series of 4.0 liters to 15 liters. The new generation of commercial engines adopts the latest combustion technology and design concepts with high efficiency, environmental protection and intelligent features, bringing low emissions, low energy consumption and improved driving experience."
Xing Min, Executive Vice President and Secretary General of China Internal Combustion Engine Industry Association, said, "The new generation of internal combustion engines from Dongfeng Cummins features higher efficiency, lower emissions, more reliable performance and a wider range of application scenarios. I believe that with the continuous efforts of Cummins as well as colleagues in the internal combustion engine industry, we will continue to see more efficient, environmentally friendly and reliable internal combustion engine products come out and make greater contributions to the promotion of the development of the global energy power sector."
Gas Engine Outperforms and Gains Market Recognition
In the heavy truck market, the natural gas trend is sweeping the industry, and Dongfeng Cummins has successively launched two natural gas engines, 15-liter and 6.7-liter, which satisfy the National VI stage b emission. Up to now, the market sales of Dongfeng Cummins' 15-liter engine will soon exceed 20,000 units, and the 6.7-liter natural gas engine will also be launched this year.
Since its launch, Dongfeng Cummins Z15N gas engine has won positive feedback from the market with its performance of high horsepower, low gas consumption and high reliability.Z15N gas engine has a displacement of 14.5 liters, a maximum torque of 2,600N‧m, and a brake power of up to 270kW, which is ahead of the industry level.
This engine has a low speed and high torque, taking into account the power and economy, and is suitable for the application scenarios of express transportation, LTL logistics, coal transportation, sand and gravel transportation, etc.; the application of Cummins two-stage three-way catalytic (TWC) technology provides stable emission; the optimized position of the detonation sensor and the control software, the advanced crankcase ventilation system and the fuel filter enhance the reliability of the engine; and the innovatively-designed exhaust gas recirculation system, further integrates the intelligent control system to protect the users. The innovatively designed exhaust gas recirculation system, integrated with intelligent control system, ensures users' efficient operation and reduces gas consumption by about 5%-10%, which helps customers of logistics enterprises to reduce costs, increase efficiency and operate reliably.
Explore new opportunities and open up new markets
In the face of market changes, the only way to be invincible is to be adaptive. In addition to its efforts in the gas market, Dongfeng Cummins will strengthen its linkage with Eaton Cummins AMT to provide users with efficient, safe, fuel-efficient, comfortable, reliable and worry-free experiences through the integrated power chain of commercial vehicle engines and off-road engines.
In terms of new energy, Eaton Cummins is also exploring new opportunities. The single-engine electrified hybrid products, which have been formally put on the market this year, have also gained recognition from customers. The hybrid product introduces a single-engine electrification system, adopts a dual-motor configuration, does not require battery configuration, and has a fuel saving rate of 35~40%, which creates a good "tool" for customers to reduce costs and increase efficiency. In addition, for the specific application scenarios of 4.5t~18t vehicles, Dongfeng Cummins has also developed hybrid products with P2 structure, realizing the function of PHEV plug-in hybrid, which is applied to light trucks with a fuel saving rate of 20%~25%.
It is close to the domestic transportation working conditions and industry reality. In the future, Dongfeng Cummins will continue to upgrade and strengthen the features of high attendance, low energy consumption, ultra-reliable and strong power, so as to bring efficient and low-cost operation guarantee to more logistics enterprises and customers.
