Car brand does not do ZTE! These engines ensure that we are not subject to anyone!


ZTE, one of the country’s largest communicators, has been pushed to the brink of survival almost overnight because of bans by American hardware companies on the sale of parts, goods, software, and technology.

The reason is nothing less than the lack of core technology in the hands of ZTE. In this regard, Huawei, its competitor, is far more successful than ZTE. Because Huawei has its own chip "Kylin", the fate is firmly in their hands.

The importance of the core technology is so important at this moment. For a time, everyone in the industry is in danger and has been rethinking whether the line of overreliance on the core technology of foreign companies is safe. Similarly, the same is true for the automotive industry. Many fans have issued "If our car industry is also stuck on the neck, will not be like ZTE, suffered the catastrophe?" questions.

As an industry that opened earlier and introduced advanced global competition to the industry earlier, how many core technologies are now mastered in the development of the automobile industry? In other words, can our car's "heart" engine be self-sufficient? Cang Ge made these answers for everyone today.

The "China Core" in the Automotive Industry

There is no doubt that compared with the exterior, the development of the engine can highlight the technical level of a car brand. In the traditional image of the past, the engine was a heart disease for China's autonomous auto companies. Do we have an "engine" that belongs to our own nation and can reach the world level?

If we put aside the narrow concept of "autonomy" (such as reference, reverse research and development, purchase of intellectual property rights, commissioned design and development, etc.), some domestic brands can be said to have achieved many gratifying results, and some engines have already been The level of foreign large companies.

Chery: 1.6T GDI Engine

When all cars made in China were made of Mitsubishi engines, only Chery took a wave of forward research and development, and for so many years they persisted, and they achieved great success. Engines, gearboxes, and other areas had major breakthroughs.

Chery's third generation engine, the 1.6TGDI turbocharged direct injection engine, is a Chery self-developed, high-performance engine with completely independent intellectual property rights. In the future, there will be a 1.2TGDI three-cylinder engine and a 1.6 based on this engine. TGDI high-power version is available.

This major technical performance has reached or surpassed some of the same-level engines of international luxury brands. It is another important breakthrough for Chinese brands in the engine core technology field and represents the leading level of domestic automotive power technology. This engine has achieved a major breakthrough in terms of power and performance. Its maximum power output is 190 horsepower, and its output power torque peaks at 275 N·m. The key is to increase power to 87.61 Kw/L. Especially in terms of power, thermal efficiency and advanced component integration technology, it has reached the level of technical performance of world-class branded engines.

Changan: 2.0T engine

Changan's 2.0T engine was developed by Changan headquarters and the Changan UK R&D center. It took six years from the start of the project to mass production. At the same time, Changan named the product “blue whale” for 6 years. Chang'an currently has the largest displacement and highest engine class.

This engine has a maximum power of 171kW and a maximum torque of 360N·m. In this "blue whale 2.0TGDI", we can see many advanced technologies, such as double VVT, direct injection in the cylinder, variable displacement oil pump and so on. It is understood that Chang'an this 2.0T engine is 100% positive research and development, applied for 74 patents, of which 24 invention patents, Changan in research and development strength can not be underestimated. From the engine point of view, this engine's performance is satisfactory.

SAIC: 1.5T engine

This engine is a typical example of Sino-foreign cooperation. SAIC and GM have jointly built this engine. Therefore, this engine is available on the Roewe RX5 and Encore, which is the result of Heli's research and development. The engine is at the world's top level in terms of power and fuel economy, and it does not lose to the Japanese and German systems.

This 1.5T engine uses many energy-saving and emission reduction technologies. Like the direct-injection technology in the center, this technology contributes to the improvement of power and thermal efficiency; the double VVT ​​can do the Atkinson cycle; and the exhaust manifold integrated in the cylinder head has the advantage of shortening the warm-up time. Reduce emissions at cold start. At high loads, it is also possible to avoid high exhaust temperatures leading to sintering of the three-way catalyst, no need for excessive fuel injection, and lower fuel consumption.

BYD: 1.5T engine

BYD is a relatively early-achieving engine independent research and development company among its own brand cars (swears to use glass and tires, all must make their own), although its early autonomous reverse development of BYD371, 473, and reverse Mazda's BYD's 483,488 are quite satisfactory. There are no bright spots. However, afterwards, the 1.5T engine coming from the EA211 has become a housekeeping product based on past experience.

BYD's G5, S6, S7, Si Rui, Qin, Yuan, Song and other models are also equipped with this engine. It can be matched with manual transmission and dual clutch transmission, and can be applied to BYD's self-developed plug-in hybrid system. Its reputation is better.

Geely: 1.8T engine

The engine was first developed since 2009. In 2010, Geely successfully acquired Volvo. In the course of its research and development, Geely acquired the Scriptures from Volvo and shared a 50% supplier system with Volvo, which eventually created the 1.8TD. Won the "China Hearts" 2015 top ten engine.

This 1.8TD second generation engine uses today's hottest new technology. New technologies such as in-cylinder direct injection, continuously variable valve timing for intake and exhaust, centrally controlled sodium-filled valves, and supercharger and exhaust manifold integration are all installed on this engine.

At present, this second-generation 1.8T engine has increased its power by 12.5%, increased its torque by 20%, and significantly improved its fuel economy.

From the core technology point of view, Geely's 1.8TD engine adopts the current nine advanced international advanced technologies and is at the top level in China. From the core data, the engine is even superior to the public in terms of core indicators such as power and fuel consumption. EA888 second-generation engine.

Written at the end:

The policy of “bringing in” the auto industry brings not only the brand of car that is piped, but also brings with it sufficient competition, the development of related supporting industrial chains, and talented people. These are the soil for independent growth. Although we are currently at a distance from the world's high-end engine camps, we still can achieve the mainstream level.

Today, we are the world's largest auto market and a big automobile country. At the same time, we are also advancing toward the road to a powerful automobile country!
