At present, Chery Tiggo 8, as the sales leader of Chery, seems a bit weak and unreliable, so the new generation Tiggo 7, as a compact SUV with mainstream size, is very important in Chery's product sequence. In addition, for those consumers who have potential demand for Chery models, the size of Chery's SUV is basically the level of Tiggo 7 and Tiggo 8, so I want to give you an in-depth interpretation of the new generation Tiggo 7.
The interpretation of the new generation of Tiggo 7 is a comprehensive and big project, and I can only scratch the cocoon, bit by bit. For a long time, China's high-tech products, whether airplanes, ships or automobiles, are generally called "heart disease", that is, the engine has always been a problem, or there is no engine at all, or its performance is backward. Under the long-term suppression of joint venture vehicles, the automobile industry is not as good as renting. Therefore, our focus and the first step is the engine. Let's talk about the engine of this new generation Tiggo 7PRO. After reading this most representative Chery 1.6TGDI engine, we can basically see the overall engine level of Chu Chery.
All along, I have a view that the promotion of knowledge, technology and level can never be achieved overnight. For example, if a manufacturer suddenly claims to have mastered the technology of Zentraedi, your first normal reaction should be to doubt rather than believe, because it is illogical. The accumulation of technology needs a little long-term accumulation, time and effort, and a process. I think this sentence can be used for Chery and myself. My own understanding of cars is gradually improved in the long-term accumulation process.
I am the owner of Chery, 1.5T Tiger Eight. Although I prefer my 1.5T EFI engine, it's only because I'm too lazy to worry about maintenance and just want to comfortably meet this special demand. In terms of comprehensive strength, the strength of this 1.6TGDI engine on the new generation Tiger Seven PRO is obviously the strongest engine in the same displacement of Chery and its own brand.
If nothing else, just give a simple example. I know very well that the indexes of this 1.6T in-cylinder direct injection engine are better than those of Mercedes-Benz 1.6T engine, and the torque, power rise and torque curve are better. I actually tested it, and it is really better than Mercedes-Benz 1.6T model. I mean the 1.6TGDI model of Tiggo 8, so we won't take out BUG models like Starrange LX and the new generation Tiggo 7PRO, which is a bit bullying.
At the same time, Chery's 1.6TGDI engine is also very reliable. Since mass installation, all high-end models of Chery, including Starway and Jiewei, have been matched, and there is no news of mass problems. Besides, he is so fuel-efficient under the premise of such strong motivation.
For the above reasons, I have always been curious about this Chery 1.6TGDI engine, and I have been studying hard, and I have always wanted to tell my riders about Chery's engine. Before a comprehensive and in-depth study, I was curious about what factors and efforts made this excellent engine, so I spent a year or so studying, observing and testing experience, consulting experts in the industry, and understanding the engine principle and design process to study this Chery 1.6TGDI engine, hoping to understand the mystery of this engine technically and write something with real technical depth.
Finally, I got some results, mainly to satisfy my personal curiosity, but also to reveal the ultimate secret of this engine, so I will start a series of in-depth articles to analyze the details and mysteries of this engine from today.
Where did Chery's 1.6TGDI engine come from?
Everything has a beginning. Did Chery ever have such an excellent engine out of thin air? Even the Monkey King, a natural stone monkey, must have a stone in the background. In fact, what many people don't know is that Chery auto start started from developing and producing engines. From the early introduction of second-hand production lines to the production of 480 engines.
As far as I know, Chery divides its engine product sequence into three generations, and the 1.6TGDI model is the representative of the third generation engine. Strictly speaking, the development process of this 1.6TGDI engine is actually very long.
The engine project started in 2008 and was jointly developed by Chery and AVL. However, due to various constraints and market environment problems, this engine has been under development as a technical reserve project and has not been mass-produced. At that time, the research and development of this engine was aimed at the highest emission standard at that time, and its maximum torque had reached 420 Nm.
Friends who know a little about the engine will feel a little scary when they see this data, because in fact, even the 2.0TGDI engine that Chery will install next year has a peak torque of only 385 Nm, while the 2.0T high-power version engine used by Volkswagen's main model Audi series has a peak torque of only 385 Nm, which shows the technical level of this engine.
It can be seen that the torque of 1.6TGDI engine mass-produced by Chery is very conservative, and this engine has great potential.
To take a step back, before mass production, it was always said that there were two versions of 1.6TGDI, the low-power version, which is now on the market with a torque of 295Nm；; The other is a high-power version, which was later cancelled. Its peak torque is 320 Nm. The reason for the cancellation is uncertain. I guess it's because Chery changed its plan to launch a 2.0TGDI engine, so the product positioning originally reserved for the 1.6TGDI high-power engine was changed to 2.0TGDI.
Therefore, friends who want greater displacement and stronger power in the future can wait for this 2.0TGDI, which should be installed on a series of Chery models, including the Tiggo 8 and the Starway series.
There are many digressions.
At that time, the 1.6TGDI engine was said to have been tested on the Land Rover Aurora and achieved good results. Later, it was not listed for reasons we didn't understand.
Later, this engine project started again, and the whole market environment has also changed a lot. At the same time, with the accumulation of R&D strength and the growth of the team, Chery has completely separated from AVL, and its engine design style has also changed significantly from the original design style provided by AVL.
As an old owner of Chery, I can feel this change. For example, the engine models originally designed by early AVL are basically European-style, specifically, they prefer high-speed power output, while low-speed power is weak, whether it is 48 1 series or 473 series. The two styles are similar. Now Chery's second-generation engines, such as 1.5T EFI models and third-generation engines,
At this time, the Chery 1.6TGDI engine was directly developed according to the emission standard of National Sixth B, and the original design was completely updated on the basis of retaining the original cylinder block. Finally, it was successfully mass-produced on 20 18 and sold on 20 19. It is used in Chery's new generation Tiggo 8 and the new generation Tiggo 7PRO just listed.
At this point, I have clearly explained the origin and ins and outs of this 1.6TGDI engine on Chery's new generation Tiggo 7PRO model. In the next article, I will first describe the comprehensive performance of this 1.6TGDI engine, and then make an in-depth interpretation. Thanks for your support.
