When it comes to Guangzhou Automobile Chuanqi, everyone's first impression will be "the product value of always online". No matter whether it is the independent MPV Chuanqi M8 or the SUV dark horse GS4, GS8 and other products, it gives people a very good impression. A car brand that can obviously conquer consumers by its product value, now GAC Chuanqi emphasizes "technology Chuanqi" and released it at the 22 Beijing Auto Show? "Huge Wave Power" technology brands.
not only Guangzhou automobile chuanqi, but also many independent brands have undergone great changes at the 22 Beijing auto show. From the previous "vehicle display" to the current "technical area", it shows that the development of autonomous vehicle technology has reached a new height.
ten years ago, China automobile brand gave people the impression that it was more like an assembly plant, with others' technology, backwardness and poor quality, which left a bad impression on consumers. GAC Chuanqi reversed the image of independent car companies with "positive research and development", and then "positive research and development" led the development direction of independent brands.
At the 22 Beijing Auto Show, Julang Power's brand-new powertrain platform was released, which demonstrated the achievements of GAC Chuanqi on the road of technological transformation. As the head enterprise of its own automobile brand, GAC Chuanqi now puts forward the road of digital transformation, which involves many aspects, among which the transformation to a technology-based enterprise is emphasized, which is also increasing the hard power of GAC Chuanqi on its own development road.
according to che shijun, GAC has invested more than 3 billion yuan in research and development. From January to June 22 alone, the number of new patent applications of Guangzhou Automobile Group has reached 927. Not only that, the first internal incubation technology innovation company of Guangzhou Automobile Group has also been registered.
when foreign automobile brands announced that their technology could make the maximum thermal efficiency of engines reach 4%, 41%, or even 43%, I believe many people were not impressed, and they questioned the technology of autonomous engines: Can they catch up?
The emergence of Julang Power has undoubtedly boosted the spirit of independent technological innovation, and made new breakthroughs in the two major fields of engines and gearboxes. It can be said that the products under this platform have been injected with "black technology".
julang power engine covers three platforms: 1.5L, 2.L and DHE, all of which use GAC GCCS combustion control system technology. At present, the representative models of the three platforms are the third generation 1.5TGDI, the third generation 2.TGDI and the fourth generation 2.ATK engines. Among them, the thermal efficiency of the third generation engine exceeds 4%, the lifting power reaches 1kW/L, and the lifting torque reaches 2 Nm/L.
As for the fourth generation 2.ATK engine (special for hybrid power), it achieved a technical breakthrough, reaching the highest thermal efficiency of 42.1%! This is the representative of the highest thermal efficiency of autonomous engines at present, even higher than that of Toyota and Honda engines.
julang power engine can achieve higher thermal efficiency, and one of the most important factors is the application of GAC GCCS combustion control system technology. This technology is the achievement of repeated experiments among the design of combustion system, virtual visual simulation of in-cylinder process, prototype test of combustion system and reconstruction of combustion indicator diagram.
application of GAC GCCS combustion control system
taking the fourth generation 2.ATK engine as an example, Atkinson cycle and GAC GCCS combustion control system are combined to achieve an ultra-high compression ratio of 15.6, which means that the engine has better power performance.
Intelligent thermal management technology and engine low friction technology
Not only that, Julang Power Engine also applies intelligent thermal management system and optimizes the power loss caused by friction. In order to make the engine run in the best working condition, through the application of intelligent thermal management system (high-power electronic water pump, thermal management module, cylinder head shunt water jacket), the internal hot spots of the engine are accurately adjusted.
in terms of reducing the internal friction of the engine, advanced technologies such as low-friction lubricating oil, DLC (diamond-like) coating technology, electronically controlled fully variable oil pump and roller bearing have all appeared, and the friction loss has been reduced by 2%.
Low-temperature exhaust gas recirculation technology
For turbocharged engines, GAC's "low-temperature exhaust gas recirculation technology" realizes the recycling of low-energy pure exhaust gas after turbines and catalysts, and the most direct result is that it can achieve 5% fuel saving effect.
julang power transmission currently covers three plATforms, namely WDCT, at and DHT. it is equipped with the electro-hydraulic control system pioneered by GAC, and applies the latest technologies such as multi-objective pressure control, dual-pump time-sharing control and segmented linear flow control. The representative models are 7WDCT gearbox, 8AT gearbox and G-MC electromechanical coupling gearbox on hybrid vehicles.
It is worth noting that the sum transmission efficiency of 7WDCT transmission reaches 96%, and the shift response is as low as .2s, and it has won the title of "Top Ten Transmission in the World". As for the G-MC electromechanical coupling transmission, it can not only realize various working modes, such as pure electric, extended range, hybrid and braking energy recovery, but also carry out intelligent optimal combination according to power demand, and the fuel saving rate is over 35%.
technology brands's subordinate models of Julang Power have been applied to different types of cars, SUVs and MPVs produced by GAC Chuanqi.
The brand-new Chuanqi M8 at the p>22 Beijing Auto Show
According to Che Shijun, Chuanqi GA8, GS8, M8 and other flagship models are all equipped with the third-generation 39T engine under the 2.L platform, that is, the 2.T engine. The third generation 39T engine can achieve a maximum power of 185kW and a maximum torque of 39N? M, official data show that the cumulative sales of models equipped with this engine have exceeded 3, units.
The second generation Chuanqi GS4
Not only that, Chuanqi GS4, known as the dark horse of SUV, also completed the second generation vehicle update earlier. The new car is equipped with the third-generation 27T engine under the 1.5L platform, that is, the 1.5T engine. The engine can achieve a maximum power of 124kW and a maximum torque of 265? N? M, strong power, comprehensive fuel consumption has dropped significantly.
in the future, we will also see GAC Chuanqi's hybrid vehicle equipped with 2.ATK+G-MC electromechanical coupling transmission, leading its own brand vehicles into the era of fuel consumption 4.
of course, the further development of GAC Chuanqi engine field not only consolidates its advantages in hard power, but also has far-reaching benefits for consumers. Under the blessing of GAC Chuanqi's "Great Wave" power, all new cars of GAC Chuanqi will make a great leap.
GAC Chuanqi's third-generation engine has more powerful power, lower fuel consumption and more durability than the original series engines. The 2.ATK+G-MC engine, which will be installed in the hybrid vehicle of GAC Chuanqi, has a thermal efficiency of 42.1% and quickly climbed to the second level in the world. The measured idle noise is as low as 57.6 decibels, and the quietness is greatly improved compared with previous models. A more intelligent control and management system can further enhance the realm of vehicle integration.
Summary:
All of the above are the achievements of GAC, which are truly built on the road of technological innovation of self-improvement, thus innovating its models and rapidly enhancing its technological advantages and market competitiveness.
From the case that Guangzhou Automobile Chuanqi transformed into a technology enterprise and released Julang Power, it can be seen that the domestic engine technology achieves the highest thermal efficiency of 42.1%, which is the first shot for independent brand technology innovation.
