Bitauto News On March 18, the "2022 Automotive Powertrain International Summit Forum" directed by the Passenger Vehicle Powertrain Professional Committee of the China Internal Combustion Engine Industry Association (hereinafter referred to as SCP in English) was digitally connected The cloud live broadcast was successfully held.
Guests from industry associations, scientific research institutions, well-known universities, automobile manufacturers and parts and fuel suppliers focused on the theme of "breaking the dual carbon situation" and discussed energy structure changes, industry development trends, and hybrid technology. We conducted in-depth discussions on topics such as Chinese brands gathering strength to improve.
Achieve "carbon neutrality" in 2060 and the automotive industry has an arduous task of "carbon reduction"
In 2020, my country officially proposed that "carbon dioxide emissions will strive to peak before 2030 and strive to reach a peak by 2060" the development goal of achieving carbon neutrality before the end of the year. At present, China is the world's largest carbon emitter, and the road transportation sector is one of the important sources of carbon emissions in the country. China's total number and increase of motor vehicles rank first in the world. Therefore, whether China's automobile industry can complete the "carbon reduction" task as scheduled or even ahead of schedule plays a crucial role in whether the entire country's strategy can be realized.
Wang Ruiping, senior vice president of Geely Automobile Group, chairman of SCP, and chairman of APS, believes that Chinese brands still have a lot of room for development in terms of size, and the opportunity for the electrification transformation of the automobile industry will be fleeting. , enterprises must seize the opportunity to follow up on the changes. The realization of the "double carbon" goal of the automotive industry requires the joint efforts of OEMs and the entire road transportation industry chain.
The theme of this forum is "Breaking Dual Carbon", and its main purpose is to discuss the diversification and hybridization of vehicle power systems under the transformation and upgrading of China's automobile industry during the implementation of the "double carbon" goal. Power technology route.
The increased weight of hybrid technology has become a new development direction for car companies
Although industry authorities have somewhat different assessments of the contribution of hybrid and electric to reducing carbon emissions, hybrids can greatly reduce fuel consumption. The views on vehicle carbon emissions are consistent. At the same time, the hybrid travel experience is more in line with the actual car usage needs of Chinese consumers.
In addition, from the perspective of the overall environment, the rapid rise in battery raw materials that began last year has interrupted the downward trend of new energy costs that has lasted for many years. The triggering of the power electrification plan may change the path towards "sustainable cost reduction". direction. At the same time, this year’s conflict between Russia and Ukraine has caused the price of nickel metal to skyrocket, which has worsened the cost of lithium batteries. Likewise, as the conflict between Russia and Ukraine has become protracted, oil prices have also continued to rise. The pressure on oil costs has increased, stimulating consumers to choose new energy vehicles. All of these have increased confusion. The weight of mobile technology in the layout of car companies.
The cost of hybrid power is half or less than 1/4 of the cost of EV power. At the same time, it has the dual advantages of fuel-saving new energy and convenient refueling of fuel vehicles. Hybrid is not only a fuel-saving machine, but also It is a comprehensive pursuit of economy, power, comfort, convenience and intelligence.
Taken together, hybrid technology, which was once marginalized by various car companies, is back on track. At present, domestic BYD DM-i hybrid models are selling extremely hot, and Great Wall Lemon DHT hybrid Several products under the platform have also attracted a lot of attention. Geely's new Thor hybrid car Xingyue L, built with a heavy investment, will also be launched soon. In addition, hybrid technologies such as Changan i-DD and Chery Kunpeng DHT are under intensive research and development. It can be seen that hybrid vehicles Automotive technology has returned to the embrace of the industry and has been "entrusted with important tasks" by various car companies.
Who can break the Japanese monopoly on the new hybrid track?
For a long time, when it comes to hybrid technology, the first thing many people think of is the hybrid technology of Japanese Ryota, whether it is Toyota's THS power split technology route or Honda's i-MMD power series-parallel technology route. , basically represents the current mainstream form of hybrid technology, so how can independent car companies achieve transcendence?
On October 31 last year, Geely Automobile officially released the global power technology brand-Thor Power, and the world-class modular intelligent hybrid platform-Thor Zhiqing Hi·X. It can be said that in key technologies It has completely surpassed the Japanese "Liangtian" and set a new global hybrid benchmark.
Its first mass-produced 3-speed hybrid electric transmission, DHT Pro, is the most compact hybrid-specific transmission in the world so far.
DHT Pro adopts 3 gear ratios, with a maximum output torque of 4920N·m and a torque ratio of 41N·m/kg, the highest in the world! The P1 generator switches without induction, bringing silky smoothness; the P2 drive motor + 3-speed combination makes power available at any time. Hi· Quickly achieve high-speed overtaking. Picture: DHT Pro 2
Secondly, the dedicated hybrid engine DHE15 is the world's first mass-produced supercharged direct injection hybrid engine, which uses high-pressure direct injection, supercharged intercooling, Miller cycle, and low-pressure EGR. Four advanced technologies, the thermal efficiency is as high as 43.32%, which is 41% better than the highest level of Japanese hybrid power. Its maximum torque reaches 225N.m, and the torque per liter exceeds that of Japanese competing products by 71%. The maximum power reaches 110kW, and the power per liter exceeds that of Japanese competing products by 41%. %; 1.5L displacement, 2.5L performance, bringing more than 40% fuel saving efficiency.
Finally, the hybrid system that can be upgraded by FOTA is also the only one in the industry. It has up to 20 intelligent working modes, unlimited iterations, and is always new.
In addition, Raytheon Zhiqing Hi· , REEV and other hybrid technologies, which are highly scalable.
It is understood that the Raytheon Hi· In the next three years, it will provide a variety of power combinations including strong hybrid, long-range plug-in hybrid and extended-range hybrid, and be installed on more than 20 models of brands such as Geely and Lynk & Co. Picture: Geely Xingyue L
It can be said that Raytheon Power and Raytheon Hi· In addition, Geely has also formed a global R&D system layout in the areas of pure electric ecology, battery replacement, and new fuels. ?
Editor’s comment: In recent years, Chinese brands have also shown an overall upward trend in the field of power system research and development. After experiencing the process of following and running together, they have even reached a partial lead. Many brands Automobile companies have been at the forefront of the world in the field of hybrid engines. The thermal efficiency of power brands such as Geely and BYD has exceeded the 41% mark; in the field of new energy, brands such as Geely and Hongqi have also gradually conquered the use of methanol and hydrogen fuel in internal combustion engines. Technical difficulties in application. All these highlight the world's leading position in domestic engine research and development levels and eliminate the impression of backward traditional technology. From catching up to following, Chinese brands are accelerating and overtaking on the new track. Taking "dual carbon" as an opportunity and using intelligence and electrification as breakthroughs, we believe that the "double carbon" goal of the automotive industry will be achieved faster.
