The summit meets the same as the continuous upward technological ascent
Scientific and technological innovation wins the new energy track
The competition in the new energy track is essentially the competition of key core technologies. Dongfeng has launched 26 new energy models in the 14th Five-Year Plan, and has independently controlled a number of key core technologies such as SOA centralized electronic architecture, 10-in-1 high-efficiency electric drive, solid-state battery, 800V+4C fast charging, etc., and firmly grasped the competitive initiative of new energy transformation in its own hands.
The test of the second half of new energy is the integration and innovation of intelligence and electrification. By building the Dongfeng Yuexiang intelligent brand, Dongfeng independently controls core technologies such as intelligent cockpit, intelligent driving, intelligent vehicle control, and intelligent ecology, and works with leading ICT companies such as Huawei to build a new ecosystem of open cooperation. Adhere to two-wheel drive and accelerate the seizure of the "new highland" of technology.
You Zheng, member of the Standing Committee of the Party Committee and deputy general manager of Dongfeng Company
Introduce Dongfeng New Energy's scientific and technological innovation achievements and planning
"We name the power brand with 'Mach', which represents Dongfeng's technical pursuit of always being one step ahead of others and always striving for one, and on behalf of creating a pleasant driving experience for users. To create China's best power solutions, Dongfeng has been leading and surpassing. You Zheng, member of the Standing Committee of the Party Committee and deputy general manager of Dongfeng Company, said, "55 years of car manufacturing accumulation, the strong backing of 59 million users, and a huge technical 'reserve' give us the confidence and strength to become a winner on the new energy track." ”
Power innovation leads to technological change
The Mach PHREV is setting a new standard for hybridization
In the evening, Dongfeng released the Mach electric hybrid PHREV technology, which pushed the industry's hybrid technology to a new height and brought China's hybrid technology into a new generation with new standards.
Mach electric hybrid PHREV jumps out of the shackles of traditional inherent hybrids, and with a minimalist and exquisite structural design, it has successfully integrated the two major hybrid technology schools of power shunt and series-parallel connection in the industry, which has the advantages of both schools and makes up for its disadvantages. This configuration only uses one planetary row, two pairs of fixed-shaft gears, and two sets of synchronizers to achieve multi-gear series-parallel and dual-mode power splitting, and uses the power shunt for gear shift at one time in the industry, which can control the engine speed more smoothly and achieve CVT-like silky shift and ultimate energy saving.
Yang Yanding, President of Dongfeng R&D General Institute
Released Mach hybrid PHREV technology
Mach electric hybrid PHREV is equipped with industry-leading electric drive, hybrid special engine, industry-leading i-Control intelligent electronic control system and high-safety and durable battery, with the four system advantages of "strong configuration, strong heart, strong brain, and strong armor", realizing the integration of a variety of new energy drive modes and advantages. It can be pure electric, and it can be driven more efficiently than plug-in hybrid in a car, and the pure electric driving experience of the extended range car can also solve the range anxiety of the pure electric car, so that users do not have to be entangled.
With the blessing of the i-Control intelligent electronic control system, Dongfeng Mach electric hybrid PHREV is equipped with an industry-leading AI predictive energy management system, which can achieve dual prediction based on travel road conditions and driving habits, and adopts self-learning scene recognition AI algorithm to automatically implement the optimal control strategy.
A special hybrid engine with ultra-high thermal efficiency is the indispensable core of an efficient hybrid system, and it is also a "strong auxiliary for Zui". In recent years, Dongfeng has continued to lead the industry in the breakthrough of core technology of hybrid special engines, and the thermal efficiency has continued to set a record for the thermal efficiency of hybrid special engines, creating the industry's first high thermal efficiency of 41.07% three years ago, and 45% in 2023, which is the current industry high record of authoritative certification, while the thermal efficiency of the engine under development has exceeded 47%, and will exceed 48% in 2026, and the new technology pre-research of thermal efficiency exceeding 50% is being carried out.
Dongfeng's new generation of high-efficiency hybrid special engine innovatively applies four key technologies, including variable geometry turbocharged VGT technology, global coupling low-pressure EGR control technology, high-pressure four-time injection technology, and ultra-lightweight design engine piston, to achieve a high thermal efficiency of 45.18% in mass production, which is the first and only one in the industry.
In terms of battery, Mach battery has built a super high-strength battery framework through multi-dimensional support structure and multi-dimensional structure safety design, created "military-grade safety armor", and strengthened the quadruple safety of battery cells, passed the rigorous safety test far beyond the industry standard, and obtained the industry's authoritative safety certification. It is worth mentioning that Dongfeng's self-developed lithium dendrite self-repair technology is the first in the industry to be mass-produced and applied, which greatly alleviates the battery attenuation, can improve the battery life by 33%, and ensure that the battery is fully charged and discharged for more than 2,000 times, which is much higher than the industry's general level of 1,500 times.
The Mach hybrid PHREV can also realize the integrated design of multi-energy bodies from "gun" to "wheel", and the authorized certified oil-electric conversion efficiency is as high as 3.66kWh/L. In addition, the all-scenario adaptive noise control technology of hybrid vehicles can ensure that the interior noise increases by less than 1 decibel when the engine is involved, and the body vibration is less than 0.01G, and the user almost does not feel it, such as falling leaves silently. Even under the extreme working conditions of rapid acceleration and overtaking of the feed, the noise increment into the car can be controlled within 3 decibels, which is far lower than the level of about 8 decibels in the same level.
