Many people buy a car just because it is big and domineering, but it needs enough power to support it. In the past two years, domestic cars have become more and more domineering, and the improvement of product quality is also obvious. What is more gratifying is that the research and development of domestic brand engines is also on the right track. In addition to the conventional 1.5T power, an engine with a displacement of 2.0T or even higher has been introduced.
Who has the better technical level among these domestic 2.0T engines? Today, we will evaluate the 2.0T engines of the four domestic giants Great Wall, Geely, Changan and Chery.
65438 +0? Great wall 2.0T
Looking back on the development history of Great Wall Motor, engine technology has long been recognized by users. As one of the third largest engines in the world, we can see this Great Wall 2.0T engine in the 20 19 China Center Top Ten Engine List. It is worth mentioning that this is the sixth time that Great Wall Motor has won this award after 2009, 20 10, 20 13.205438+07, which shows that Great Wall has a good strength in the engine field.
At present, what is more demanding for engines is the requirement for emissions. With the official opening of the National Sixth Standard, this Great Wall 2.0T engine is a high-performance, low-fuel consumption and low-emission engine built by Great Wall Motor in three years.
According to the specific data, this Great Wall 2.0T engine has a maximum torque of 385 Nm and a maximum power of 165kw. Compared with Volkswagen EA888-DKX and BMW B48A20C, this engine not only achieved the data transcendence, but also carried the product performance. Haval F7X's 100-kilometer acceleration has also surpassed joint venture brands such as Tiguan L and BMW X 1.
This brilliant performance is mainly due to the more advanced in-cylinder direct injection technology adopted by this Great Wall 2.0T engine. Through better fuel atomization, every drop of gasoline can be fully burned, the exhaust manifold can be optimized, the engine temperature can be better controlled, and the fuel consumption can be reduced. Intelligent thermal management keeps the engine in good running condition.
Number two? Chang 'an 2.0T
Changan Automobile has made great achievements in SUV field in recent years, which is also inseparable from the improvement of its core product strength. This Changan 2.0T engine was jointly developed by the Changan headquarters team and the British R&D Center. It took six years from concept to mass production. This blue whale engine can be described as a sword for six years!
Let's take a concrete look at the performance of this engine. The maximum torque output of Blue Whale 2.0TGDI engine is 360 Nm at 1750rpm, and it can last up to 3500rpm. The highest power can reach 170kw, even surpassing the 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 engines, such as dual VVT, in-cylinder direct injection, variable displacement oil pump, high tumble combustion technology and so on. It is reported that this engine is all products of Changan based on forward development. There are 74 patents and 24 invention patents alone. Chang 'an's R&D strength should not be underestimated.
Number three? Geely 2.0T
You may not be familiar with Geely's 2.0T engine, because most of Geely's models are equipped with 1.5T and1.8t. As a car company with the highest sales volume in China, Geely, as the first car company to actively develop, still attaches great importance to engine research and development, especially after the acquisition of Volvo, and has absorbed many foreign advanced concepts.
This 2.0T engine is mounted on the newly launched Xingyue of Geely, which is a completely self-developed engine. You can see many core elements of Volvo on this engine. The performance is also very good. Maximum power 175kw and maximum torque of 350 Nm. Xingyue matched the 8AT gearbox, and the acceleration time of 100 kilometers was only 6.8 seconds. It is worth mentioning that Geely's engine cylinder is made of all-aluminum alloy, which is more in line with the development of the times and reduces fuel consumption to some extent.
Number four? Chery 2.0T
Not many people know about Chery's 2.0T. Like Geely, its own brands still put more energy into the engines of 1.5T and1.6t. As one of the earliest domestic brands focusing on engine research and development, Chery has made great progress, but the layout of 2.0t engines is obviously later than those of the above-mentioned brands such as Great Wall, Chang 'an and Geely.
However, the power of R&D is still there. It took only two years for Chery to develop its own 2.0T engine. However, considering the stability and matching degree with gearbox and other components, Chery delayed the time to market.
It is reported that Chery's high-end SUV Starway VX will be equipped with this 2.0t engine for the first time, and the book data of the news is not bad. The maximum power can reach 180kw and the maximum torque can reach 380 Nm. The book data still kills the above three models, but it is uncertain whether Chery will reduce the engine torque for more stability after real mass production.
Conclusion:
By analyzing and comparing the 2.0T engines of independent brands, we can see the progress of independent brands and the significance of independent research and development for a car enterprise. It is hoped that independent brands will make greater efforts in R&D and realize the rapid development of high-end manufacturing industry in China at an early date.
