"Wang Dong, good news, our engine technology has made a breakthrough, and the turbocharging project has been successful!"

After receiving the phone report, Wang Haoan immediately asked someone to drive to the engine R&D center in the suburbs of Beijing.

"Wang Dong, you see, the displacement of this engine is 1.5L, but the power is not weaker than the 2.0L displacement. At speeds above 1,000, the performance is better than that of the 2.0L, but at more than 110 miles, the performance is about the same. ”

Wang Haoan listened to the introduction and nodded with satisfaction: "It's a good job." And what about the downsides?"

It's not enough to talk about the advantages, but also to know the disadvantages before we can consider whether to mass produce and bring them to the market. Some small shortcomings do not matter, but some shortcomings that affect the handling must be addressed.

"The disadvantage is that the service life of the engine will be reduced, and it may be scrapped for 500,000 kilometers. Moreover, it is necessary to use materials such as magnesium alloy, which are lacking in China, and the cost will increase a lot. ”

"At the time of starting acceleration, the performance was slightly weaker, the failure rate had not been tested for a long time, and the specific service life had not been tested for a long time, and the results were now calculated through computer data simulation. ”

Professor Liu is very recognizant of the current technology, and what he wanted to test in the past had to be calculated manually, plus the actual test, where is the computer simulation test so convenient now.

He is an old guy, and the computer operation is actually not very good, but there are many doctoral students under him, and those who do postdoctoral research work all know about computers and have strong hands-on ability, so he only needs to be responsible for some core theoretical derivation.

Huaxia's automobile engine scrap mileage is 600,000 kilometers, and the age is 12 years, but in fact, there are many cars that are still running for more than 12 years.

The service life of foreign engines can reach 20 years, and the recorded peak mileage is 4 million kilometers, these are the data announced by foreign countries, Wang Haoan does not know whether it is true or false, but it is completely unnecessary.

Not to mention twenty years, ten years later, the technology of the engine has been updated for several generations, how many people will still drive such old cars?

Therefore, in fact, the life of the international mainstream engine has been reduced to about 15 years, but the number of scrapped kilometers in many countries is more than 600,000.

Huaxia set this standard because Huaxia Automobile not only has a short engine life, but also a chassis life that is not so long, not only because of technology, but also because Huaxia's road conditions are not as good as those developed countries.

In the next decade, the speed of road construction in China will surge. Transportation is also one of the pillar industries in China at this time, and not only highway construction, but also railways, ships, and aviation will be vigorously developed.

There is no way, there are too many people in Huaxia, and the geographical area is also large, so it is really inconvenient to travel without development.

For example, the main development of transportation in North America is aviation and highways, and in terms of railways, although North America claims to be the first in mileage, in fact, the speed is really not very good, and freight transportation is the main purpose of railways.

The main transportation network in China is still the railway, and then the road, shipping and airplane, from which the railway does not belong to the transportation cloth can be seen from the status.

But road construction is on the agenda, with a better road network, the service life of cars can also be increased, and driving on a flat concrete road is certainly not the same as driving on a potholed country road.

Wang Haoan thought for a while: "Find a way to improve the service life, there are not many requirements in terms of life, it can exceed the national standard of 12 years, and the mileage should reach 600,000." ”

It is not required to exceed much, but it cannot be lower than this value, otherwise it will not be able to be marketed. Even if the top gives the production approval, the peer will blow it out for you, and others will think it is an inferior product when they hear it.

Cars are big, and few people want to drive them for three or five years now. Even if you have these ideas, the life of the engine is not long, and the value of the used car must be very low, not cost-effective.

"How long will it take to completely perfect this technology, and can the requirements for materials be reduced?"

"It may take about five months to perfect this technology, and the requirements for materials can be reduced, but they need to be adjusted, and it may take a few months to complete this technology, and it will also increase the weight and volume of the engine. ”

Replacing magnesium alloys with steel naturally increases the weight. Moreover, the performance of steel is not as good as that of magnesium alloy, and it is possible to increase the thickness in order to ensure the service life, which also increases the volume.

It would be best if there was enough magnesium alloy, and they could complete the technology as soon as possible. After the completion of one model, other models can be adjusted in a short time.

Although turbocharging is not a new technology, many turbocharged engines abroad have been mass-produced, and the response from consumers is also good, but in China, this is a first-class technology, and it is different from Sanling's technology, and the future prospects will be broader.

The technology that Sanling came up with and the domestic joint venture belongs to the international second-rate end, and the technology that has been basically eliminated by car companies in developed countries.

Even if it is upgraded in the future, it is still a second-rate technology and will not be eliminated in a short time, but compared with the engines of other international cars, it is still a scum.

This technology is the focus of Wang Haoan's requirements, and some breakthroughs can be made in such a short time, and Wang Haoan also lamented that the money was not spent in vain.

After this technology is perfected, the engine R&D center can be put on the production line and start selling engines, which will inevitably be purchased by many domestic car companies.

"Then let's improve this technology first, and I'll solve the magnesium alloy thing. "It's not that magnesium alloys can't be bought, but that the price is high. But the wool is out of the sheep, the price of the material is high, and the selling price is high.

Their engine technology is leading in China, with labor costs and local protection policies, it is definitely more competitive than foreign imported engines, unless foreign car companies also take this technology from domestic joint ventures.

And even if they are joint ventures, the price of magnesium alloys they purchase will not be much cheaper, and the technology with independent intellectual property rights is not supported, and the leaders are not so stupid to buy other people's technology at a high price and come back to the joint venture.

"Wang Dong, in fact, if you want to speed up the progress of technical improvement, it would be better to add some funds. Professor Liu said tentatively.

Wang Haoan looked at Professor Liu: "Then you make a report, I'll think about it." ”

The progress of the other three R&D centers will have to be considered before deciding whether to give more money to this side. And how much time can be reduced if more money is given?

If you say that you can come up with an extra 10 million US dollars and come up with perfect technology in a month, Wang Haoan will give it immediately. But if it is increased by 10 million US dollars, the result is only ten days and half a month in advance, and Wang Haoan will not give it now.

The technological gap between their R&D center and foreign countries is not more than ten days, but more than ten years!
