In recent years, as people’s wallets have become bigger and bigger and their spending power has increased significantly, cars have entered thousands of households.
Many people buy a car because they want it to be big and domineering, but even if it is large, it still needs enough power to support it. In the past two years, the styling of domestically produced cars has become more and more domineering, and the improvement in product quality has also been obvious. What's even more gratifying is that the research and development of domestic brand engines is also on the right track. In addition to the conventional power of 1.5T, engines with 2.0T or even higher displacement have also been launched.
Among these self-contained domestic 2.0T engines, who is better at the technical level? Today we will review the 2.0T engines of the four domestic giants Great Wall, Geely, Changan, and Chery.
NO.1? Great Wall 2.0T
Looking back at the development history of Great Wall Motors, the engine technology has long been recognized by users. As one of the world's third largest engine selections, we can see this Great Wall 2.0T engine in the list of China's top ten engines in 2019. It is worth mentioning that this is the sixth time Great Wall Motors has won this honor after 2009, 2010, 2013 and 2017, which shows Great Wall's considerable strength in the engine field.
The current requirements for engines are higher than those for emissions. With the official launch of the National VI standards, and against the background of corresponding energy conservation and emission reductions around the world, this Great Wall 2.0T engine is what Great Wall The car took three years to build a high-performance, low-fuel consumption, low-emission engine.
In terms of specific data, this Great Wall 2.0T engine has a maximum torque of 385 Nm and a maximum power of 165kw. Compared with joint venture brand engines of the same displacement, such as Volkswagen EA888-DKX, BMW B48A20C, etc., it not only achieves the data surpass in the performance of the installed products. The Haval F7X's acceleration from 100 kilometers to 100 kilometers also surpassed joint venture brand cars such as Tiguan L and BMW X1.
The main reason for such outstanding performance is that this Great Wall 2.0T engine adopts more advanced in-cylinder direct injection technology, which allows every drop of gasoline to be fully burned through better fuel atomization. , the temperature exhaust manifold is optimized, the engine temperature is better controlled, and fuel consumption is reduced. Intelligent thermal management keeps the engine in good operating condition.
NO.2? Changan 2.0T
Changan Automobile has made great achievements in the SUV field in recent years, which is also inseparable from the improvement of its core product capabilities. This Changan 2.0T engine was jointly developed by the Changan headquarters team and the British R&D center. It took 6 years from concept to mass production. This Blue Whale engine can be said to be a six-year hard work!
Let us take a specific look at the performance of this engine. The Blue Whale 2.0TGDI engine reaches a maximum torque output of 360 Nm at 1750rpm, and can continue to 3500rpm. The maximum power can reach 170kw. This performance even surpasses Great Wall's 2.0T engine in the 2.0T field.
In addition to good data performance, we can also see many core advanced technologies of the engine, such as dual VVT, in-cylinder direct injection, variable displacement oil pump, high tumble combustion technology, etc. It is reported that this engine is all a product developed by Changan based on forward development. It has 74 patents alone and 24 invention patents. Changan’s R&D strength cannot be underestimated.
NO.3? Geely 2.0T
You may not be very familiar with Geely’s 2.0T engine, because most of Geely’s models are equipped with 1.5T and 1.8T. As a domestically produced Geely, which ranks among the top car companies in terms of car sales, is the first car company to develop forward. It still attaches great importance to engine research and development. Especially after acquiring Volvo, it has learned from and absorbed many advanced foreign concepts.
This 2.0T engine is installed in Geely's newly launched Xingyue. This completely independently developed engine has many core elements of Volvo in it. Performance is also very good. The maximum power is 175kw and the maximum torque is 350Nm. Xingyue is matched with an 8AT gearbox, and the acceleration time from 100 kilometers to 100 kilometers is only 6.8 seconds. It is worth mentioning that Geely’s engine block material is all aluminum alloy, which is more in line with the development of the times and reduces fuel consumption to a certain extent.
NO.4? Chery 2.0T
Not many people know about Chery’s 2.0T. Like Geely, independent brands still focus more on 1.5T and 1.6 Regarding T engines, as one of the first domestic brands in China to focus on engine research and development, Chery has made early progress, but the layout of the 2.0T engine is obviously later than the above-mentioned Great Wall, Changan, Geely and other brands.
However, the R&D strength is still there. It took only 2 years for Chery to develop its own 2.0T engine. However, considering the stability and matching with the gearbox and other components, Chery postponed it. time to market.
It is reported that Chery’s high-end SUV Xingtu VX will be equipped with this 2.0t engine for the first time, and the book data revealed are not bad. The maximum power can reach 180kw and the maximum torque reaches 380 Nm. The book data still beats the three previously mentioned models. However, after actual mass production, it is not certain whether Chery will lower the engine torque for more stability.
Conclusion:
By analyzing and comparing 2.0T engines of independent brands, we have seen the progress of independent brands and the importance of forward independent research and development for a car company. It is hoped that independent brands will work harder in research and development and realize the take-off of my country's high-end manufacturing industry as soon as possible.
