From April 19th to 22nd, the 3rd World Congress of Internal Combustion Engines organized by the Chinese Society of Internal Combustion Engines officially opened in Tianjin. Focusing on the hot and cutting-edge issues in the field of intelligent technology of internal combustion engines, experts, scholars, engineers, business executives, teachers and students of colleges and universities, and representatives of industry associations from all over the world participated in the discussion. Dongfeng Commercial Vehicle was invited to attend this industry event, once again demonstrating its outstanding strength and forward-looking vision in the field of internal combustion engine technology research and development. Yin Yong, director of the Advanced Powertrain Technology Development Office of the Powertrain Department of the Technology Center of Dongfeng Commercial Vehicle Co., Ltd., shared Dongfeng's fruitful achievements and strategic deployment in internal combustion engine technology innovation, energy conservation and emission reduction, and intelligent development as a representative guest, and vividly presented the magnificent picture of Dongfeng Commercial Vehicle in the industry to innovate and lead the trend for the guests.
The technological achievements are brilliant, and the innovation drives forward.
As a technology pioneer in China's commercial vehicle industry, Dongfeng Commercial Vehicle has always adhered to the innovation-driven development strategy and is committed to independent research and development and breakthroughs in core technologies of internal combustion engines. In recent years, Dongfeng Commercial Vehicle has made a number of significant achievements in the field of internal combustion engine technology, such as high-efficiency and energy-saving technology, low-carbon emission technology, clean energy application, etc., constantly refreshing industry standards, providing a strong impetus for the realization of more efficient and cleaner transportation solutions.
So far, Dongfeng Commercial Vehicle has successfully launched a series of commercial vehicles equipped with high-efficiency and energy-saving internal combustion engines, such as Dongfeng Intelligent Driving Heavy Truck, Dongfeng Tianlong Gas Vehicle and other star models, which use advanced combustion technology, optimized thermal management system and intelligent control strategy, which can significantly improve fuel and gas economy, reduce operating costs, and create real value for users.
In order to actively respond to the call of global carbon emission reduction and the national "double carbon" policy, Dongfeng Commercial Vehicle has also made significant breakthroughs in emission control technology. Its self-developed Longking Power series products all meet the national VI emission standards, and adopt high-efficiency SCR (selective catalytic reduction) system, EGR (exhaust gas recirculation) technology and advanced after-treatment devices to greatly reduce the emission of harmful substances such as NOx and PM, demonstrating the firm practice of environmental protection responsibility as a state-owned enterprise.
At the same time, in the face of the trend of energy diversification, Dongfeng Commercial Vehicle actively explores the research and development and application of clean energy such as hydrogen and natural gas in internal combustion engines. As early as the 2nd World Internal Combustion Engine Conference in 2021, Dongfeng Commercial Vehicle launched the industry-leading 13L Longqing DGi13 gas engine, which leads commercial vehicles into a new era of green power with the characteristics of high thermal efficiency and low emission. In 2023, Dongfeng Commercial Vehicle's ammonia diesel engine and ammonia hydrogen engine will go through 6 months, and will complete more than 270 and 370 single product tests of key components including hydrogen nozzles, hydrogen rails, hydrogen regulator valves, hydrogen supply pipelines, special pistons, etc., as well as more than 300 control system developments, once again refreshing the height of the field of clean energy internal combustion engines, showing its deep accumulation and leading advantages in the industry.
Forward-looking layout and leading industry change.
While adhering to the technological innovation of internal combustion engines, Dongfeng Commercial Vehicle has a forward-looking layout for the future, actively responds to the wave of energy structure transformation and intelligence, and not only draws the strategy and goal of "green and intelligent wings" for its own development, but also contributes Dongfeng wisdom to the expansion of the sustainable development blueprint of the commercial vehicle industry.
In September 2023, at the opening ceremony of Dongfeng Motor's 8th Science and Technology Innovation Week and Automobile Carnival, the strategic goal of Longqing Power 2.0 "Green and Smart Wings" was officially released. With the help of Dongfeng Commercial Vehicle's patent group layout and industrial upgrading in core technologies such as combustion control technology, brake safety technology, engine cooling technology, low-carbon fuel, and intelligent control of power chain, Longking Power 2.0 has made technological breakthroughs in low-carbon fuel engines, hybrid powertrains, pure electric vehicles, fuel cells, domain control architecture, AI machine learning, MPC model predictive control, and SOA central computing platform control architecture.
Based on "more economical and low-carbon drive", Longking Green Wings will expand from a single assembly to an integrated power chain, forming four typical power chains: diesel/gas/low-carbon fuel power chain, hybrid powertrain power chain, pure electric power chain, and fuel cell power chain, to better meet the needs of customers in different applications and stages; Cloud and other intelligent perceptions, predictive and integrated integrated control of the power system, and intelligent diagnosis and predictive maintenance technology are realized.
Share wisdom and draw a blueprint for the future.
At this internal combustion engine conference, Dr. Yin Yong, a researcher-level senior engineer of Dongfeng Commercial Vehicle, was invited to give a keynote speech on "Research on the Combustion Technology Route of Hydrogen Ammonia Internal Combustion Engine for Commercial Vehicles", mentioning in the sharing that commercial vehicles are the focus of carbon emission control, but due to their many use scenarios, the low-carbon and zero-carbon technology of commercial vehicles adopts multi-energy and multi-technology routes has become an industry consensus. In order to compare the different combustion technology routes of hydrogen internal combustion engine/ammonia engine, Dongfeng Commercial Vehicle has carried out a number of R&D tests, such as: building a hydrogen and ammonia multi-energy test platform, carrying out hydrogen cylinder direct injection, active and passive jet, hydrogen ammonia active and passive jet and other tests on the same engine, and at the same time carrying out simulation research on the above different routes of hydrogen and ammonia, and comparing the thermal efficiency and detonation characteristics of different combustion technology routes, in order to provide a basis and reference for the industry to determine the technical route of low-carbon fuel.
Under the spotlight of the 2024 World Internal Combustion Engine Congress, Chinese commercial vehicle brands have demonstrated to the world their persistent pursuit and innovative power for the development of "green, efficient, reliable and intelligent", as well as the responsibility and responsibility to discuss challenges, share wisdom and draw the future together. Dongfeng Commercial Vehicle also once again demonstrated its industry leadership and influence as a benchmark enterprise for commercial vehicles with its fruitful achievements and foresight in the field of internal combustion engine technology. We look forward to stimulating the spark of wisdom for the high-quality development of China's internal combustion engines and setting a benchmark for the green and smart future of the commercial vehicle industry."
