Right now, with the rapid development of self-owned brands, despite the rapid progress of domestic cars in the design and body work, it is undeniable that we do have a certain gap between the engine and foreign independent brands. As the "heart" of a car, consumers have relatively high demands on the engine, but there are obvious contradictions between the hard conditions in China and such high demands, manifested in the following aspects: First of all, China's industry started relatively late with respect to Europe, its foundation was weak, its development was relatively slow, and the metal foundry industry lags behind foreign countries. The lack of high-quality casting raw materials in China is on the one hand. On the other hand, the manufacturing process of the engine cylinder body and other simple structural parts is complex and requires the metal to melt into a liquid and pour into the mold. This process is easy in the cooling and solidification process, resulting in the occurrence of residual stress, exhaust, spray of release agent and other defects. Once a problem occurs, it directly affects the product's yield and use efficiency. Second, because our country has focused on economic development and neglected basic industries, it has led to a lack of sophisticated technology and cutting-edge talent. The back and forth movement of the engine piston requires high precision. The difference is insignificant and it is lost. A little mistake, the life of the engine may be affected. Under different design levels, there is still a certain gap between the performance of products produced by our factories and foreign countries. Assembly environment is also a problem, each screw has its installation sequence and instrument detection process. If the piston gap is mixed with fine hard particles, it will produce a huge destructive force after ten million rubs. In an impetuous modern life, China lacks the sophisticated talents who can do these fine jobs. It must be admitted that the concentration of foreign companies and the control of the principles are higher than those of local companies. In the case of gaps, we need to find ways to gradually narrow these gaps after we have found problems. How to enhance the quality of supplier parts and components, how to cultivate cutting-edge talent, how to improve technology, and accelerate the pace of innovation, these are the direction of development that we are now looking at. However, it is worthwhile to affirm that our country’s industry is developing steadily and the level of education is constantly improving. I believe that after a period of time we can narrow the gap and give you the answer.
