What do you think about knockoffs?

The copycats are also divided into grades, some of which are directly bought with drawings and process manuals, which are relatively stable, such as Jialing's 70CC and the early start of the construction of the engine, these RB Honda also personally participated in technical support, support and help inspection.

There are also surveying and mapping imitations, just like the core aircraft of Taihang is the CMF-56 engine of Shanzhai Civil Aviation, the core engine of CMF-56 is a series with the F101 engine used by American bombers and the F110 engine of fighter jets. and Wu Hao's smuggling CG125 to design reverse research and development imitations, which were used for the Wujiacun Bicycle Factory. The final result was that Yangfan Factory assembled 70CC in advance for alternative use, and Yang Quan picked peaches.

Yang Quan also remembered that the construction group imitated the CJ50 model with reference to Honda's PA50 model in 79, and later when this motorcycle asked Honda for technical transformation, Honda pointed out more than 140 problems. This is the result of the imitation of the test without direct reference to the drawing.

Some people think that the design appearance and the like can be copied, but the engine cannot be copied, and it is true.

Because the engine is a high-speed rotating precision machine, there is a tolerance fit problem between each part, and the rotor also involves the problem of dynamic balance...... Hundreds of parts with errors are put together, and the error is scary.

Compared with the prototype of the copycat, both the performance and reliability are far behind, and in the end they have to be changed one by one before they can be used. The result of the time spent is not at all, and the technical difficulty is not small at all.

The designer solves this problem by relying on tolerance fit, that is, each part has a permissible deviation range, and the combination of multiple parts can also control the total error. For example, in the above diagram of the tolerance position of the hole and the shaft, the two are one-to-one. Surveying and mapping imitation also measures a small number of parts, and it is impossible to derive a tolerance range, which has to be studied afterwards.

So, there's not much work to be done. The reason why Yang Quan is willing to take over the copycat work of the ejector rod machine is because the difficulty is slightly easier than other engines, and simple does not mean that anyone can do it. From setting up the project to now looking for mass production suppliers, hundreds of thousands of funds have been invested, so Yang Quan does not dare to guarantee that there will be no problem when it comes to mass production.

Copycats can take some detours, because originality requires imagination, while copycats only need action. But cottages are not a healthy way to develop.

Yang Quan's cottage is just a stepping stone, a ticket to enter the market. The domestic autonomous cars of later generations are different, they have no way out except for the cottage, and they can't even take the step of the cottage.

As far as China's auto parts industry is concerned, the small ones are not an example, and the large products are similar to engines and gearboxes, which are almost all controlled by foreign-funded enterprises.

The increase in the localization rate that multinational automobile companies have been touting has been achieved by purchasing products from foreign parts companies in China.

The internationalization of parts and components that independent brands have been touting has gradually put China's independent parts enterprises into the cold palace. Many of the suppliers to be procured are wholly foreign-owned, holding or shareholding, and all or part of the profits of the enterprises flow abroad;

For example, there is no doubt that RB Mitsubishi has almost a monopoly on the supply of gasoline engines for all its own brand cars that cannot produce their own engines.

Mitsubishi Corporation, which has a low market share in China's vehicle market, under the matchmaking of the most intelligent leadership of the former Brilliance, set up Aerospace Mitsubishi in Shenyang/Yang in 1997 and Dongan Mitsubishi in Harbin/Erbin in 1998, respectively, to produce gasoline engines with medium displacement and small displacement, supporting Hafei, Southeast and Brilliance companies at that time.

Later, many car companies such as BAIC, Southeast, Changfeng, Zotye, and JAC that we are more familiar with are still purchasing engines from Mitsubishi.

You must know that the powertrain of a car usually accounts for 20%-30% of the cost of the whole vehicle, and the average price of an engine in Mitsubishi is about 10,000 yuan. Think about the net profit margin between 20%-30%, which is no less than the profit of a whole vehicle.

There are also EFI systems and heavy-duty transmissions.

In terms of EFI systems, in order to meet the emission requirements, all domestically produced vehicles must be equipped with EFI systems. Germany's Bosch, the United States' Delphi, and RB Denso have almost monopolized all of China's EFI market shares, of which Germany's Bosch has a dominant market share, exceeding 60%.

From domestic brands to foreign brands, from cars to trucks, from gasoline vehicles to diesel vehicles, Chinese consumers contribute thousands of yuan in profits to the above three foreign companies for every car they buy. There is a saying in the automobile industry that the main engine factory works for the engine factory, and the engine factory works for Bosch.

In terms of heavy-duty transmissions, Eaton of the United States and ZF of Germany not only control the research and development and sales of heavy-duty transmissions worldwide, but also almost monopolize the heavy-duty transmission market in China.

At the time of China's reform and opening up, that is, around the 80s in the first two years, Eaton and ZF transferred the heavy-duty transmission manufacturing technology to Shaanxi Automobile Manufacturing Plant and SC Automobile Manufacturing Plant respectively for the introduction of Steyr heavy-duty truck models at that time, which later evolved into the two major hegemons of China's heavy-duty transmission market: Fast and Qi J gear.

Later, two international transmission giants have set up factories in China. No matter how fierce the competition in China's heavy-duty truck market is and how the profit margin falls, the two foreign companies lurking behind the scenes, Eaton and ZF, will snicker and reap the benefits.

From the above facts, we can easily see that the core and key component technologies are controlled by foreign capital, and China's own brand automobile companies can only complete the market research, product definition, appearance and interior design in the early stage, stamping, welding, painting, final assembly, testing in the medium term, and dealer recruitment and sales management in the later stage.

Among them, the preliminary market research is mostly entrusted to AC Nielsen and other international market research companies to complete, the exterior design is mostly entrusted to the streets of Turin, Italy are many car design companies, and the interior design is mostly entrusted to Johnson Controls and other companies in the United States.

In the later stage, the standard of dealer recruitment is even lower, no matter whether you have sold cars before, and whether you are a company that sells cables or electricity before, as long as you have the funds and agree with my so-called "corporate culture", you can obtain the right to sell.

As long as you can "integrate global car manufacturing resources", you can save a whole vehicle. China's local car companies are becoming more and more like assembly stores in computer cities, or more and more like some mobile phones, taking the purchased parts and putting them together, polishing the appearance with good intentions, and then bragging about all kinds of things.

The only way to transform the role of a manufacturing base in developed countries into a real independent R&D is to do so.

The necessity of independent development lies in the fact that it is the most effective way and way to learn technology, and learning is the only way to develop organizational ability, and independent development is the most effective way and way to learn using foreign technology. It is precisely those who oppose independent development and the use of foreign technology that oppose independent development.

In his previous life, Yang Quan also saw that Chery and several other autonomous cars worked hard to absorb foreign technology and take its essence to form its own things, which is what he wants to do now.

Absorb CG125 ejector rod machine, and strive to develop 150CC, 200CC, or even larger displacement engines. These engines also have to conform to China's national conditions, with high horsepower, simple structure, practicality, daily use, and easy maintenance, which are all points that need to be paid attention to now.

What kind of motorcycle will be needed in the market within ten years, no one knows better than Yang Quan.

Within ten years of economic development, people with spare money in their hands need some products of industrialization to express their differences. At this time, the motorcycle is a product of symbolism and practicality, which not only reflects the identity, but also has practical value.

Whether in the city or in the countryside, this kind of two-wheeled or three-wheeled bicycle is urgently needed, and the kind of fuel tank sits on a small child, the wife sits in the back, and 2 to 4 people ride together. You need to load vegetables, chickens and pigs on the motorcycle, and even drag a small truck truck behind the motorcycle by yourself, so that you can easily pull goods and do business.

At this time, the land is dusty, and many people do not pay attention to maintenance, and will continue to use the engine oil after it turns into oil sludge. Paper filters that are also used for air filters have become as hard as dirt walls made of dust. It is also used when the drive chain is loose to the maximum adjustable and the chain box is hit up and down.

This situation is common, and the urgent needs of the market are also spurring Yangfan Factory to establish a correct design concept. When Yang Quan decided at the meeting that the next generation of products would be 150CC, everyone sat up straight and no one spoke.

The questioner has already given the question, and whether the questioner can give the answer or not, he should show the will to fight and move forward without flinching and passionately.
