How strong is China's automotive industry? Domestic netizens have not reached a consensus on this issue. Some people think that China's automotive industry is on the rise, and domestic technology is overtaking in curves. But some people believe that China's automotive industry is large but not strong in core technology or rely on imports from abroad.
In fact, the development situation of China's automotive industry is very complicated, and in some technical fields, China has achieved a counterattack, such as bearings, engines, etc., and China has even achieved a large number of exports to foreign countries. However, at present, pure domestic cars are not particularly ideal in performance performance, especially in terms of power, the gap with foreign cars is still very large, why is this?
Domestic engine strength is not OK?
Many people think that the strength of domestic cars is not as good as foreign cars, the main reason is that the engine performance is insufficient, there have been people who think that China's engine manufacturing industry has progressed very slowly over the years, and there is no comparison between domestic engines and foreign engines in performance. In fact, this is the prejudice against domestic engines, china's engine manufacturing industry has developed rapidly in the past decade, and many powerful enterprises have emerged.
The engine strength developed by BYD, Great Wall, Lynk & Co and other enterprises has long been not inferior to foreign engines. The 1.5T engine developed by BYD and Great Wall has reached 180-190 horses in horsepower, which has surpassed many established engine manufacturers in foreign countries; the horsepower of the new Honda 1.5T engine that has just been listed has reached only 177 horses, while Toyota, which has been known for engine manufacturing, has only 150 horsepower of the 1.5T engine developed by toyota. It can be seen that in terms of power, domestic engines are not inferior to foreign engines.
The domestic 2.0T engine manufactured by Lynk & Co has more than 250 horsepower, and such a powerful power has made Lynk & Co rank among the world's top in the field of engine manufacturing. In addition to power, there is also a data that is also an important factor in judging the strength of the engine, that is, thermal efficiency. Previously, foreign engines basically stayed between 35% and 37% in terms of thermal efficiency.
For the first time, domestic BYD has increased the thermal efficiency of the engine to more than 40%, and then domestic companies such as Lynk & Co and Great Wall have also increased the thermal efficiency of the engine to more than 40%, which also means that the domestic engine is not only powerful, but also very energy-saving, because the utilization rate of fuel is very high.
Horsepower achievement rate turns domestic cars into "paper tigers"
Many people will wonder, obviously the domestic engine is so strong, why the performance of domestic cars is so unsatisfactory? In fact, a car wants to have a strong performance of the engine alone is not enough, the engine after burning energy to generate power needs to be transmitted through the gearbox, transmission shaft and other parts of the transmission, and finally let the car drive.
In the transmission process, there will inevitably be a loss of power, and automobile manufacturers need to constantly adjust the equipment to reduce the power loss of the car in the transmission process, so that the performance of the engine can be maximized. At present, the best domestic car in terms of transmission efficiency is Harvard, but its transmission efficiency can only reach about 78%, which means that nearly 22% of the power is wasted.
The conduction efficiency of foreign car companies is basically above 80%, and the highest conduction efficiency in the global car companies is Audi, with an efficiency of nearly 99%, which is why Audi is very strong in the case of engine performance is not outstanding. Domestic technology in terms of gearbox, drive shaft and other aspects is not perfect enough. This is because there are more technical barriers in the research and development of transmissions, drive shafts and other devices, which cannot be achieved by imitation, but require continuous accumulation of experience and exploration to achieve.
Chinese companies in the gearbox and other components of the research and development is very late, so it is unrealistic to catch up with foreign countries in a short period of time, but this is also urgent, there is no shortcut in the field of technology research and development. Although the current development of the domestic automotive industry is not particularly sufficient, we have been able to see that the entire automotive industry is developing in a good direction, and I believe that soon we will be able to see China's automotive industry achieve a counterattack.
summary
For Chinese automakers, there is still a long way to go to catch up with foreign technology. In addition to the gearbox, drive shaft, there are many parts such as body beams and crankshafts in China, which are still lagging behind foreign countries, so although the development of the domestic automobile industry has made small achievements, we cannot be proud and complacent, nor can we relax our vigilance.
Only by constantly breaking through ourselves can we meet a better future. For domestic consumers, should have confidence in domestic cars, today's domestic cars have been different from more than ten years ago, and now domestic cars have the strength to compete and compete with foreign cars, so don't blindly be arrogant, domestic cars can also be an option that everyone considers when buying a car.
At present, domestic BYD, Great Wall, Changan and other cars have not much performance performance, in the cost performance of many cars is more crushing many foreign cars, so we should give domestic cars some opportunities to perform, do not blindly deny the progress of domestic cars.
"Actual combat" when the external strength in the middle of the cadre? The problem with domestic cars is not the engine
"Parameters have not been lost, actual combat has not won", where is the problem of domestic cars?
