Wang Shufu and others are not optimistic about the self-developed engine, which makes Qin Feng smack his tongue.


    Although Qin Feng was reborn, he also knew that even after more than 20 years, domestic engines would not work. For example, aircraft still have to import Russian engines.


    However, Qin Feng has always believed that this is the reason for not paying enough attention and not introducing competition. For example, European and American countries have private funds to enter this field.


    Once there is competition in any field, it promotes progress. Otherwise, if one family is dominant, there will be no catfish effect.


    Therefore, Qin Feng seems that as long as he acts as this catfish, even if he loses money, he may be able to promote the improvement of China''s engine technology.


    After all, it''s still early. This year is 1994. There''s still a lot of time.


    But now, the attitude of Wang Shufu made Qin Feng feel very hung.


    "Dong Qin, the engine is the most important part of the whole heavy industry." Wang Shufu said, "all the traditional power engines on the market now, whether gasoline, diesel or in-line, V-type, horizontal opposed and other forms, can be collectively referred to as reciprocating piston engines. This type of engine appeared more than 100 years ago. Although the current engine has been optimized, the basic structure has not changed. So it''s not difficult to build an engine alone. Now undergraduates majoring in machinery should be able to design it. "


    "Why is that difficult?" Qin Feng asked.


    For a non Polytechnic graduate, I think engine manufacturing should not be so difficult.


    "The requirements of today''s cars for engines are not simply to convert chemical energy into mechanical energy. Combustion efficiency, emission, reliability and other factors need to be considered. And as I said before, reciprocating piston engine has a history of more than 100 years, and it has developed into a very mature technical system. If you want to overthrow this system and find another way, it is impossible. " Wei Jianjun''s words are earnest and sincere.


    "And then?" Qin Feng is curious.


    "The former rotor engine is a good example. In order to avoid being merged, Mazda of Japan was forced to develop rotor engine and spent a lot of manpower and financial resources. In the end, the 30-year efforts from the 1960s to the 1990s still left a pause on the RX8. Even in its most glorious period, it is not the mainstream of the world. Therefore, if you want to apply new technology to overtake on corners, it will not work for your own brand engine. " Li Chuanfu smiled bitterly.


    "Er, you''ve been talking for a long time, but I''m still very confused!" Qin Feng looked confused.


    "Well, let''s say so. If you want to do anything new on this system, it is even more difficult. Any and technology has its physical bottleneck. Now human engine technology is very close to this limit, which is the same as climbing Everest. The task of climbing the top in the last 100 meters is often the most difficult. And this requires a lot of technology accumulation. Let alone whether other people''s technology has patent protection. Even if other people directly "bring it" after the patent period has expired, it is just to avoid detours in the research and development process. " Wang Shufu said.


    Qin Feng scratched his forehead.


    "Mr. Qin, it''s like someone telling you that the double cooked pork needs pork, pepper, garlic sprouts and bean paste. Can you succeed in doing it for the first time? Maybe if you can''t grasp a small detail, you can never do the taste of the hotel. Therefore, even if the design drawings and raw materials are given, it is very difficult and time-consuming for a manufacturer with weak experience to copy. This is just like the current Chinese food recipes are sold all over the world, but even if ordinary crooked nuts follow the recipes, they still can''t make a table of Chinese food. We still find the Chinese food they cooked very unpalatable! " Wei Jianjun said for example.


    "However, our manned spacecraft have been safely launched many times, and stealth fighters and aircraft carriers have been in service. Is the technical content of building an engine higher than this top project?" Qin Feng retorted curiously.


    "That''s another matter! First of all, for things like spaceships and weapons and equipment, their market is single, and the market competition is very limited, and their investment is often regardless of cost. This cost ratio is never considered, and there is no need to consider its economic benefits! " Wang Shufu said.


    "But the car is different. It is a commodity, and all brands compete in the same market. Then the car is not built. It is finished when it meets the design standard. More importantly, we should push it into the market and be recognized by the market. This must consider the "cost performance" Li Chuanfu added.


    Qin Feng smacks his tongue.


    "I believe that China can build a world-class engine with a power of more than 500kW and installed on a compact car of its own brand, with a comprehensive fuel consumption of no more than 10L per 100km. But if the cost of this engine is military grade, it becomes meaningless. " Wei Jianjun shrugged, "not to mention, even if it is a military engine, we are also very backward!"


    "What is the difficulty for us to develop our own engine?" Qin Feng patted his forehead. No matter what, he asked directly.


    The three thought for a while and spoke in unison.


    "For us, the biggest problem is lack of experience and weak technical reserve. Therefore, it is very difficult for us to build an engine with both cost performance and high technology. The biggest reason is the problem of technical reserve and development cost. To put it simply, Mazda''s rotor engine that doesn''t make money is a lesson from the past. " The three said.


    "Unlike Mazda, it failed and survived. We can''t afford such failure! " Wei Jianjun said, "we are just an emerging private heavy industry enterprise. We should be responsible for our own profits and losses and feed so many people! We can''t afford to fail! "


    Wang Shufu and Li Chuanfu also nodded. They agreed with Wei Jianjun.


    In any case, everything else can be developed independently. But the engine, even if they want to, is really powerless. No matter how much money you spend, it is difficult to make revolutionary changes. On the contrary, in terms of cost, it''s better to buy engines from other factories. That would be more economical.


    "No! This one, we can''t admit our fate! " Qin Feng shouted and waved his hand to express his dissatisfaction. "We Chinese, once an ancient civilization, can''t even build an engine well in modern times? I don''t believe it! I absolutely don''t believe it! We can use imported engines now, but we must develop them from now on. No money, I invest. Without technology, I have to get technology to learn when I buy, rob and steal. But I won''t accept it. Admit defeat now! If so, we will never have our own autonomous engine! "


    Qin Feng will never admit defeat!
