My landlord
Engines, especially heavy-duty engines, are known as the jewels in the industrial crown.
In China's aviation industry, the lack of advanced heavy-duty engines has led to severe heart disease and forced to be controlled by others. Our 919 large passenger aircraft was seriously delayed and delayed in delivery; our strategic bombers, our advanced fighters, were also severely constrained by engine constraints. The engine, as the heart of the industrial industry, has always been a pain for our country.
However, in the automotive industry, our engine problems have been basically solved, whether it is the commercial vehicle field of heavy trucks, or the passenger car field dominated by cars and SUVs, domestic engines have caught up with the world's advanced level and have fully realized independent control. A few days ago, the Great Wall Motor 3.0T+9AT power system rolled off the production line, which was the crown jewel of the automobile engine and became an exciting event in the industry.
The pinnacle of autonomous powertrains
What is the significance of this 3.0T+9AT? It is necessary to start with the strategic significance of large displacement engines.
At present, the independent brand in the small displacement engine has been completely self-controllable, economic cars, compact SUV and other models do not have to worry about power problems, but if the independent brand goes up, if high-end, large displacement high-end engine is essential.
However, at present, the high-end engines of the independent camp are seriously lacking, and only a very small number of people such as FAW Hongqi have truly achieved large-scale mass production.
Among them, the Hongqi 3.0T engine is a supercharged engine, and the market generally recognizes that this 3.0T engine and the Volkswagen engine are similar in structure and technology. Some people believe that the Hongqi 3.0T engine is based on the Volkswagen 3.0T supercharged engine and is not a completely independent core technology.
In addition, BAIC BJ90 is also equipped with a 3.0T engine, but this 3.0T engine is actually derived from Mercedes-Benz, from research and development to manufacturing all technologies are controlled by Mercedes-Benz, BAIC is just to use it, and there is still a long way to go from being independently controllable.
Compared with Hongqi 3.0T and BAIC 3.0T, the 3.0T engine independently developed and manufactured by Great Wall can be said to have achieved true autonomy and controllability, completely filling the domestic gap.
In the field of automatic transmission, in fact, the threshold is higher than the engine, at present, domestic car companies that can independently produce engines abound, and there are only a few who can independently develop and manufacture automatic transmissions, especially those that can develop and manufacture 9AT gearboxes at this level. Great Wall Motor's 9AT gearbox has also achieved a breakthrough of zero, representing the highest level of independent brands in the field of transmissions.
Enough to compete with the Ashkenazi ABB
This power system is not only leading enough in China, but even if it is placed in the world, it can also rank among the top masters.
In terms of advanced technology, this 3.0T engine incorporates top hard-core technologies such as dual injection and double VGT supercharging, with a maximum power of 354 hp and a maximum torque of 500 Nm, while applying a 48V light hybrid BSG motor, the peak torque can be further increased to 550 Nm. The engine is not only powerful, the greater advantage is energy-friendly, in order to fully reduce fuel consumption, squeeze every drop of fuel power, the engine through the Miller cycle, full map oil pump and a series of advanced technologies, to achieve 38.5% high thermal efficiency, this thermal efficiency in the same level of 3.0T engine dare not say absolutely first, at least is the only two levels, the real top master.
If compared with the international engine of the same level, the Great Wall set of 3.0T+9AT is also enough to compete. Analogies can be made:
Audi Q8 is equipped with a 3.0T engine with a maximum power of 340 hp and a maximum torque of 500 Nm;
BMW 7 is equipped with a 3.0T engine with a maximum power of 340 hp and a maximum torque of 450 Nm;
The 3.0T engine equipped with the Mercedes-Benz S has a maximum power of 435 hp and a maximum torque of 520 Nm under the support of high-efficiency motors;
The Great Wall 3.0T power system, which will soon carry the tank 500, has a maximum power of 354 hp (?) ), maximum torque 550 Nm. For this, Li Jian, president of the Great Wall Motor Honeycomb E-Creation Power Research Institute, commented very confidently, "The comprehensive strength of this engine is enough to compare with the global engine of the same level."
With the 9AT transmission with the 3.0T engine, the technology is also amazing. The transmission adopts the self-developed hydraulic automatic transmission structure scheme, and innovates the patented technologies such as ultra-highly integrated hydraulic control module, redundant parking system design, high-performance torque converter, compact and efficient clutch design and intelligent control software, which can achieve a torque bearing capacity of up to 750N·m. By analogy, the BMW 7 Series and Audi Q8 have 3.0T engines equipped with 8AT gearboxes, and the Mercedes-Benz S 3.0T is equipped with 9AT transmissions.
The Great Wall's 3.0T+9AT power system truly stands at the forefront of the world.
The result of a large-displacement engine
In addition, it is particularly worth mentioning that this power system is of great strategic significance not only for Great Wall Motors, but also of great significance for the power system of China's independent camp, and even of great significance for the development of global engine technology.
Because a very obvious development trend is that international giants such as Mercedes-Benz BMW Volkswagen GM have a generally negative attitude towards the research and development of next-generation fuel engines, especially the research and development of next-generation large-displacement fuel engines, many of which have been suspended, and the models that have been developed have actually slowed down significantly. In the face of the surging wave of electrification, international giants are shifting more energy to power batteries and new energy, more on the current engine model to repair, continue to improve, for the new generation of engine research and development attitude is ambiguous.
Based on this, it is very likely that a reality is that the 3.0T engine that the Great Wall has just rolled off the production line may be the most advanced fuel engine at present, or it may be the last generation of large-displacement heavy-duty engines, representing the top level of the global power system. Because there is still a huge prospect of upgrading, this powertrain will likely remain at the forefront of the global large-displacement engine for a long time.
This time the surpassing of the medium-sized power system of Great Wall Motors may become the work of the domestic engine.
