From October 11th to 13th, the "2024 China International Internal Combustion Engine and Power Equipment Expo" (hereinafter referred to as the "Expo") hosted by the China Internal Combustion Engine Industry Association was held in Beijing.
Exhibits include four engines, the Z14, Z8.5, D6.7N and B6.2, as well as an integrated powertrain that is deeply matched to the Z14 and Win AMT transmissions. In fact, at present, Dongfeng Cummins has 14 national VI product platforms for vehicles, 7 non-road four-stage product platforms, 2 natural gas product platforms, and technical route products such as hydrogen internal combustion engines, hybrid and methanol fuels are also being actively developed and verified.
Demand-oriented
Achieve full coverage of application scenarios
"Our product layout covers from 2.5L, 3.0L, to 6.2L, 6.7L, 7.0L medium horsepower, as well as 8.5L, 10L, as well as 12L, 13L, 14L, 15L diesel power, and successfully introduced 6.7L, 15L gas power, the current layout of 14 vehicle product platform power displacement fully covers 2.5L to 15L. At the same time, with the introduction of the Winning Gearbox, Dongfeng Cummins has already realized the transformation from a single power supplier to a system manufacturer and a multi-power solution provider. Liu Daokun, director of Dongfeng Cummins vehicle engine products, introduced that in order to fully meet the needs of the market and users, Dongfeng Cummins has accelerated technological innovation at the same time, actively upgraded production lines, rapidly improved the level of intelligent manufacturing, and has built and put into use 2 new production lines and 1 transmission production line.

For a long time, Dongfeng Cummins has continued to promote the innovation and development from traditional manufacturing to "intelligent manufacturing", and has achieved a comprehensive upgrade from production and manufacturing to operation management with the help of digital transformation. Among them, the new intelligent heavy-horsepower factory production line is compatible with the mixed line flexible production of diesel engines and natural gas engines, with an engine displacement of 8.5L~15L and a horsepower of 280-660 horsepower, which greatly improves the degree of automation, and can realize more than 20 digital scenarios such as blurred grasping of robot visual positioning, AI visual inspection, offline programming of spraying robots, and intelligent inspection of robots, and greatly improves production efficiency and product quality.
In view of technological innovation and product development, Dongfeng Cummins accurately focuses on market trends and user needs, continuously improves product layout, improves product performance, especially power, economy, comfort and reliability, comprehensively improves the application experience, and creates greater value for users.
The all-new B-series 6.2L power is upgraded on the basis of inheriting the excellent genes of the classic B-series platform for typical cargo application conditions, using more advanced component systems, and through a series of technical optimizations and improvements, it has achieved a comprehensive upgrade in terms of fuel saving, power, reliability, and driving comfort.
The Z series 8.5L power focuses on the market demand of engineering transportation, especially for the application scenarios and working conditions, and has been specially developed for waterproof, dustproof, shockproof, impact-resistant, etc., with a lightweight design, which is 150-200kg lighter than the same displacement model; The steel stamping oil pan improves the ground clearance, has higher reliability and safety, and further improves the passability of the vehicle; In terms of dynamic performance, the low-speed torque and instantaneous response ability are increased by 30%, and the climbing performance is increased by 7%; Moreover, the thermal efficiency of the mass production of the two power models reaches 48%, which can achieve fuel saving of 8%-10%.
Gas-powered demand released
Rational layout to meet the challenge
Since the beginning of 2024, the demand for gas power has been further released, and at the same time, the demand for new energy has increased rapidly, and the era of diversified power in the domestic transportation industry is accelerating.
"The application scenarios of commercial vehicles are very diverse, and the new energy of light vehicles represented by pure electric and hybrid technology routes has been very clear; The scenarios corresponding to medium-horsepower models are relatively complex, and there are certain opportunities for technical routes such as natural gas power, hybrid and fuel cells; The new energy of high-horsepower models is especially blooming, such as pure electric vehicles, fuel cells, hydrogen internal combustion engines, methanol power, hybrid and so on. Liu Daokun revealed that in response to the wave of new energy, Dongfeng Cummins adheres to the principle of diversification and simultaneous development, consolidates and enhances the advantages of traditional fuel power solutions, and on the one hand, accelerates the promotion of clean energy power products represented by natural gas power; On the one hand, we will promote the development and verification of hydrogen power, including hydrogen internal combustion engines and fuel cells, with the help of resource advantages.
During this exhibition, Dongfeng Cummins D6.7N gas engine won the "Best Innovation Power Star" award for its excellent market performance. Of course, Dongfeng Cummins not only focuses on the development of medium-horsepower gas engines for the international and domestic markets, and has been highly recognized by users, but also has obvious advantages in high-horsepower gas engines, and the matching rate of integrated power chain has been significantly improved.
Dongfeng Kangfengsi integrated power chain is completely based on the Cummins industrial resources depth matching, highly integrated assembly, whether it is the underlying logic, or related data, completely interoperable and open, so the whole system is natural, matching is called "seamless", at the same time, thanks to the intelligent control system blessing, power and economy to achieve the best fit, both fuel consumption, or gas consumption have reached the optimal level.
With the pursuit of efficiency and economy in the domestic medium and heavy truck industry, and the price of natural gas has been relatively stable for a long period of time, the demand for gas power will obviously be maintained. Liu Daokun said: "Although the current market competition situation is becoming more complex, the market share of gas power will continue to increase. In the face of the new demand under the current situation, Dongfeng Cummins will continue to strengthen its technological innovation capabilities, strengthen the advantages of existing products, and continue to improve product performance and quality. ”
【Conclusion】
Under the trend of continuous release of natural gas power demand and accelerated new energy transformation, the pattern of fuel power "dominating the world" has obviously been completely broken, and the accelerated arrival of the era of multiple power has promoted the reshaping of the pattern, during which new opportunities have been born under pressure and challenges. In the face of the new situation, Dongfeng Cummins is undoubtedly prepared, as Liu Daokun introduced, Dongfeng Cummins will continue to increase investment in scientific and technological research and development, provide users with better multi-technology route power solutions, continue to promote technology upgrading and product iteration, and help users to achieve low-carbon or even zero-carbon green transportation on the road to efficiency and wealth.
