Even five years ago, domestic automobile manufacturers with little ability to independently manufacture engines and gearboxes accounted for the vast majority of automobile manufacturers in China. As a result, the "4G" series of Mitsubishi Shenji has nourished domestic car companies that are hungry everywhere for a long time.
However, in the past two years, independent car companies have changed from "stacking configuration" to "internal strength", and the powertrain formed by the engine and gearbox has become the "core competitiveness" pursued by first-line independent brand car companies. Today, when 1.5T and 1.6T have become the mainstream displacement, in fact, there are still many independent car companies that we call "first-line brands" advancing towards higher goals. Can we come up with an excellent 2.T engine and become the "big test" of the core technology of independent car companies?
so let's sort out the highlights of the 2.T engines of these first-tier car companies today.
changan 2.T blue whale engine
changan automobile has made great achievements in SUV field in recent years, which is inseparable from the improvement of its core product strength. The 2.T engine originally installed on CS95 was jointly developed by the team of Changan Headquarters and the British R&D Center. It took six years from concept to mass production, and this blue whale engine can be described as a sword in six years.
this blue whale 2.TGDI engine can reach the maximum torque output of 36 nm at 175rpm, and can last up to 35rpm. The highest power can reach 171kw, which even surpasses some joint venture brand 2.T engines in the 2.T 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 and high tumble combustion technology. It is reported that this engine is all products developed by Changan based on the forward direction. There are 74 patents and 24 invention patents alone. The R&D strength of Changan should not be underestimated.
nowadays CS85? Coupe and CS75? PLUS is also equipped with this engine, although CS75? The main sales volume of PLUS comes from the 1.5T version, but the 2.T engine has actually played the role of a technical benchmark, and at the same time promoted some sales volume, which also played a key role in boosting the overall texture and technical strength of Changan.
great wall 2.GTDI engine
recently, another car company purchased the great wall engine after sailin. BJ4, an off-road vehicle owned by BAIC, intends to equip the 2.T gasoline engine easily created by Great Wall Honeycomb.
it is rare for independent brands to sell engines to the outside world. Although SAIC and Brilliance's Xinchen Power have provided engines for other manufacturers, the engine technology of these two companies can not be regarded as completely independent in a strict sense. However, Great Wall Motor sells engines to the outside world, and it is certainly worthy of praise for the Great Wall, which does not rely on the "big factory".
At present, there are only a handful of domestic brands that fully master the core technologies of engines and gearboxes, and Great Wall is one of them. In the list of the top ten engines of "China Heart" in 219, GW4C2B of Great Wall Motor? The 2.T gasoline engine was also successfully selected, which is the sixth time that Great Wall Motor won the title after 29, 21, 211, 213 and 217.
now countries all over the world have put forward more and more strict requirements for engine technology. This GW4C2B? The 2.T engine also conforms to the global trend of emission reduction. As a new generation product of Great Wall EC platform, GW4C2B has greatly improved its comprehensive performance compared with the previous generation model. It can output a maximum of 224 horsepower at 55 rpm and a maximum of 385 Nm of torque at 18-36 rpm. Compared with the Volkswagen EA888 with the same displacement of 22 HP /35 Nm, the BMW B48A2C's 184 HP /29 Nm is even ahead of the world-class manufacturers in data.
The cumulative sales volume of Haval in the world has exceeded 5 million, which is the first automobile brand in China to enter the 5 million club, and the successful establishment of factories in Russia and India also indicates that China's automobile industry has begun to go abroad, and its own brand represented by Great Wall is also entering the world market.
GAC Chuanqi 2.T engine
Although some people say that the core technology of the 1.8T engine before Chuanqi came from Alfa Romeo, this 2.T engine is a brand-new engine independently developed by GAC Research Institute. It is also known as the strongest 2.T engine in China, and it is also the most satisfactory engine product by Wu Jian, Vice President who has led the engine product development of Guangzhou Automobile Research Institute for more than 1 years.
the 2.T engine (internal development code "4B2J1", hereinafter referred to as "39T engine") with the label of 39T, which is fully installed on the GS8 model of Guangzhou Automobile Chuanqi 22, has completely replaced the 2.T engine with the label of 32T installed on the model of 217. "39" in "39T" means that the peak torque of the engine is 39 Nm, and "T" means that the engine adopts turbocharging technology.
in terms of power output parameters, compared with the 32T engine, the maximum horsepower of the 39T engine is increased by 51 horsepower, and the maximum torque is increased by 7 Nm. At the same time, the emission standard of the 32T engine is upgraded from national V to national VI.
With the enhancement of domestic engine R&D capability and the upgrading iteration of engine hardware technology configuration in the industry, manufacturers in China and other countries have been at the same starting line at least in terms of power parameters. And the time node of fully implementing the national VI emission standard in China has also become a good opportunity for China brands to achieve technological catch-up.
39T engine is equipped with 35bar in-cylinder direct injection system and GCCS tumble combustion chamber technology, which is the key for the new engine to achieve a better balance between power, emission and fuel efficiency. At present, this 39T engine has surpassed some international mainstream 2.T engines in power parameters, which greatly enhances the competitiveness of Chuanqi brand products.
Conclusion: In the current China automobile market, mastering the core competitiveness in technology and innovation in design is the key to the success of a car model or even a car company. Today's first-line independent automobile brands have already realized this point. On the most critical technology of engines, we can finally proudly say that the moon in China is as round.
