China's automobile development is not long, although it has been catching up rapidly, and has even achieved a relatively leading position in the field of new energy, but for a long time, there is still a gap between domestic engines and overseas engines, and in the field of high-performance engines, domestic brands are still blank.
Why is it that domestic brands are not as good as joint ventures? The internal combustion engine has undergone such a long period of development, the working principle has long been familiar, why can't the independent brand make a surprising engine?
The history of the internal combustion engine dates back to about the 17th century, producing chemical energy through fuel explosions, and then converting chemical energy into mechanical energy through a piston linkage mechanism, thereby pushing the vehicle to do work.
The principle is understood by everyone, and it is not complicated to manufacture an internal combustion engine that can work normally, but it is not easy to be the top in the industry. In fact, after years of development, the progress of the internal combustion engine can not be the same day, even if the same principle, after the blessing of different technologies and processes, the engine performance is also significantly different.
Personally, I believe that there are several reasons for the slow development momentum of domestic engines
According to a company research report, in 2019, Chinese brands invested 4.2 billion yuan in research and development: Great Wall 4.2 billion, SAIC 5.5 billion, GAC 5 billion, Changan 4.5 billion, ANDD 8.4 billion.
By comparison, Toyota is $10 billion, Volkswagen is $16.9 billion, GM is $7.3 billion and Ford is $8 billion.
In contrast, the investment is directly proportional to the height of technology, and it is precisely because of the insufficient investment in engine technology that engine technology will naturally not lead the world's progress, which is an objective law.
As we all know, machining requires high-tech machine tools, the regular name is CNC machine tools. According to relevant statistics, China's high-end CNC machine tool imports are the first in the world, while Germany is the first in exports.
Among them, the high-end industry needs to use the mold, most of the current are relying on imports, although a small number of domestic enterprises can do this kind of processing equipment, but from the performance, yield, speed, stability point of view, the current domestic equipment and overseas still have a certain distance.
The car engine is a device with extremely high precision requirements, any bad pool may lead to various problems in the process of using the car, and the reputation of the independent brand has just begun to be established, and any bad pool may be destroyed.
At present, the top engine is the study of details, the so-called details in addition to the subtle data statistics of the engine, there are subtle differences in engine processing accuracy. For example, due to the different compression ratios caused by the machining accuracy, the accuracy is increased ± 0.06, the engine can increase the power and torque by 0.7%, and reduce the fuel consumption by 0.5%, which is the improvement brought by the high-precision CNC machine tool.
At present, driven by policies, major manufacturers have long since not invested all their energy in the research and development of internal combustion engines. In today's era, cars are no longer fighting engine power, new energy, automatic driving, the Internet, mobile travel has gradually replaced the internal combustion engine as a bellwether in the automotive industry.
From 2020 onwards, many brands have released the news that they have stopped selling pure fuel vehicles, and in this environment, the progress of the internal combustion engine will naturally slow down relatively.
As we all know, at present, many independent brands have launched their own hybrid models, and I personally believe that this is the best way to transition to new energy in the pure internal combustion engine.
The hybrid system also needs to have the existence of an internal combustion engine, but compared with a single internal combustion engine power, the hybrid system has relatively low requirements for the engine, mainly in terms of efficiency and fuel consumption. At present, independent brands seem to have achieved good results in the internal combustion engine dedicated to hybridization, for example, THE BYD DM-i system is the first engine developed for hybrid, and this power system can be regarded as first-class from the perspective of fuel consumption performance and overall vehicle performance.
From the current situation, the internal combustion engine has two main directions. The first is the main efficiency mentioned above, through a variety of high-tech to achieve lower fuel consumption for the purpose. However, the life of this engine will not be particularly long, and when the new energy technology matures, the hybrid engine will complete its mission and disappear into the long river of history.
The other is a top-of-the-line multi-cylinder large-displacement engine, which is mounted on a supercar or a racing car, becoming a hedonistic machine in the top crowd, realizing the triple stimulation of somatosensory, auditory and visual.
Driven by the concept of global environmental protection, the internal combustion engine has been transformed from a popular equipment into a hedonistic equipment, for example, not particularly appropriate example is the electronic watch and mechanical watch, when the electronic watch to achieve accurate time, reliable and durable, the mechanical watch has become people's pursuit of boutique technology and aesthetic items, the same is true for the internal combustion engine, when the new energy completely occupies the mainstream, the traditional internal combustion engine pursues a more high-end enjoyment.
