Chery is really an "incredible" presence in the car. It can be said that the quality is not as good as Geely, the Great Wall, Chang'an, and it can also be designed in depth, criticizing product chaos and marketing. However, only "technology" seems not to be questionable. If someone says that Chery's technology is not good or not, it is the same as hitting the muzzle of the gun, and it will often be "besieged" by many people. This is also Chery's "technology house" name in the jianghu for a long time, it can be seen that many people are used to this statement. Of course, some people think that Chery technology has been "deified", but in fact, it is not as cattle as imagined. So what is the truth? In order to answer this question, Brother Jiang still wants to speak with facts and see what technology Chery has in his hands.
1, the engine, has a technical foundation, the predecessor of chery with strong financial strength is the Anhui Auto Parts Industry Company, which was founded in 1997, and the main business at that time was the engine. As a result, Ford's used engine production line also cost a lot of money to buy. In 1999, the first engine rolled off the production line. Of course, this is someone else's thing after all. Chery's first engine, so Chery cooperated with Austria's AVL and began self-production. In 2005, the ACTECO engine, which has independent intellectual property rights, rolled off the production line for the first time. So far, Chery is also regarded as the first domestic brand derived from the motivation of research and development. At that time, most domestic brands were still buying Mitsubishi engines, so Chery undoubtedly laid the status of "technology house". At present, Chery Hongqi series has developed to the third generation, the first application is the 1.6T codenamed SQRF4J16, using aluminum alloy body, iHEC combustion system, direct fuel injection, rapid heating cooling and other technologies, the maximum horsepower is 197Ps, the maximum torque is 290 n290 n.
Chery's third-generation 1.6T engine, which began to be installed in 2018, is currently widely used in Chery, Jietu, and Xingtu brands, with good word-of-mouth and market response. It is considered to be a "divine machine". In 2021, Chery III machine will launch another 2.0T, using advanced technologies such as 350bar ultra-high pressure direct injection system, pendulum double-layer flywheel, mid-mounted VVT, and electronically controlled supercharger, with maximum horsepower and torque from the initial 254Ps and 390Nm to 261Ps and 400Nm, respectively. Chery's third-generation 2.0T engine faces the mainstream 2.0T, and Chery has no scruples and is statistically close to BMW's 2.0T high-power engine. At present, the engine has been installed on the Xingtu Youyue, Lingyun, Tiggo 8/Tiggo 8 PLUS and Jietu X90. Whether from the origin or the latest products, Chery's engine is indeed within reach. The only point of contention may be the Austrian company AVL. Someone took this to refute it. Chery's engine is not 100% self-developed. Brother Jiang really feels that there is no need to leverage this, which car brand is not so step by step?
2, the transmission CVT is gradually abandoned, and now mainly rely on the third party In 2009, Chery developed the first independent patented CVT transmission in China. At that time, almost all other independent brands relied on joint venture transmission companies such as Shenyang Mitsubishi and Tangshan Aisin, and the name of "Technology Chery" was obviously famous. In 2015, Chery sold transmission technology to Wanliyang. The purpose is to facilitate the purchase of other host factories. Although strictly speaking, Wanlin is an independent third-party supplier. But because of this technical relationship, many people like to say that the Wanliyang CVT is Chery's. I think it's good for everyone to see this, and there are two more things that need to be known. 1. Chery intends to reduce its stake in Wanliyang. After the completion of the transaction, the shareholding will be less than 1%. This means that Chery is not very confident in the Wanliyang CVT. 2, Wanliyang CVT can not match the engine with high torque. Chery is currently only installed in a few models such as the Ericsson 5, and the two main models of 1.6T and 2.0T do not match.
In summary, Wanliyang CVT is actually not a technology that Chery can master. In fact, most of chery's current transmissions rely on third parties. For example, the Tiggo 7 and Tiggo 8 series are 6MT gearboxes equipped with the entry-level version, and they are Aisin from Japan. On the other hand, the 6-speed dry dual clutch suitable for Chery's 1.5T engine, although it claims to have been jointly developed by Chery and Getlark, is actually only responsible for tuning, and the actual technical ownership is still Getrak (Magna)." For the large-scale use of 7-speed wet dual clutches in the main models of Chery, Jietu and Xingtu, it can be divided into three sources: 1. Glock 7DCT - at present, the 1.6T engine of Chery and Xingguang brands comes from it; 2, Chongqing Qingshan Industrial 7DCT - Changan Transmission Enterprise, mainly used in the Shortcut 1.6T mode; 3, Liuzhou SAIC Motor Transmission Co., Ltd. 7DCT - applied to Chery, The most controversial of the 2.0T models of Jetto and Starway is the third, the DCT380 gearbox that is consistent with the 2.0T. Zhongfan said saicki is just a substitute, and the technology and design are provided by Chery. I think this statement makes Django a little weak. Based on two points: First, DCT380 officially clarified that Liuzhou SAIC Motor Transmission Co., Ltd. independently designed and developed, and has been put into production. Why only Chery is used, it should be some kind of agreement reached between the two sides. Second, Chery has CVT technology and has also done 4AT, but has never heard of having technical reserves in the dual-clutch transmission. Suddenly saying that DCT380 is Chery's technical achievement is really hard to convince.
3, the chassis / platform has a certain technical accumulation and experience, the well-known effect is not high three major parts have said the engine and transmission, now to the chassis, it is composed of four parts of the transmission system, driving system, steering system and braking system. This is a very complex and huge system, and if you want to do it well, you often need a long period of tuning experience and technical reserves. I think you ask Chery if the chassis tuning technology can be obtained, and the whole network can't find a clear answer. However, it can be explained that Chery is the first car company to independently develop car chassis, from the earliest famous T1X platform to the later M1X, M3X, new energy special platform @LIFE. Indeed, Chery's chassis technology still has a certain technical accumulation and experience. Chery T1X platform in the automotive platform architecture prevails today, Chery's chassis / platform actually has no advantages. Geely's CMA framework, the Great Wall's lemon and tank platform, BYD's BNA framework, etc., are better than Chery in terms of fame and word-of-mouth effect. 4, Kunpeng DHT hybrid technology has highlights, but need to actually verify that in terms of new energy technology, Chery Kunpeng DHT hybrid is a bright spot, the front double motor of the 1.5T engine, the hybrid system of the rear single motor, the hybrid special gearbox with multi-gear ratio, the maximum input torque reaches 510Nm, and the single/double motor
Specific to the Tiggo 8 PLUS Kunpeng e, the official statement can achieve zero hundred acceleration of 4.9s at the earliest, directly consistent with the 4.3 seconds of Tang DM-p (2.0t), the fuel consumption of 100 kilometers of power supply is less than 5L, Tang DM-I ) 5.3, 5.5L/100km) In simple terms, it takes into account the high performance of BYD DM-P and the low fuel consumption of DM-i. Although it sounds very good, it has not yet been officially mass-produced and listed, and it is not known whether the cost can be controlled within a reasonable range, so whether it can be obtained still needs actual research. In addition to the above four projects, Jiang Ge found after the investigation that Chery has a self-developed and produced wire control system (including ESP system function) and engine ECUs. Most of the independent brands need to rely on suppliers such as Bosch and Continental. In addition to the automotive business, Chery is also involved in shipbuilding and even mastered aero-engine technology. Chery SQR D4D20 aero engine
Written at the end, in order to facilitate everyone's discussion, here are three more points. 1. As a pioneer of domestic automobile technology, Chery deserves the title of "Technology Chery". Moreover, its spirit of research is still preserved today. Therefore, so many people will "favor" Chery. 2, although Chery's technology started high, but hindered by the subsequent brand strategy mistakes, the current overall development is not smooth, this "gap" to a certain extent caused a polarized reputation; 3, in the traditional three parts, Chery's biggest short board is now on the gearbox, but it is said that it will do 8AT, so it is worth the eye; indeed, Chery's technology, is not brainless, indeed has a foundation. Of course, we don't have to be too popular, in the current domestic camp, the advantages of Chery technology are actually not particularly prominent. Moreover, to evaluate an automobile company, it is not only necessary to integrate technology, but also to integrate design, marketing, product layout, sales and other links. Otherwise, the structure becomes smaller. What do you think about this? Welcome to follow "Borderless Car Domain" and leave a comment in the comments section below to share your thoughts on Chery.
