Ding Weizhong began to study how to process this aluminum alloy cylinder head, while Jin Xiaoqiang rested at home for a few days.

The crazy busyness of this period of time really tired him.,Even if he has the consciousness of the hero of a reborn person.,But to draw so many drawings.,It's also a pretty brain-consuming thing.。

The most important thing is to draw so many parts on the drawing, and also to indicate the size of each part, as well as the allowable margin of error, and so on.

This seems to be a simple endorsement to work, but it is actually quite cumbersome to do, but fortunately, Jin Xiaoqiang has an amazing memory, and after all, he has slashed this engine many times in his previous life, and it can be said that he is extremely familiar with this engine, so he can do such a situation.

Jin Xiaoqiang rested at home, and Ding Weizhong here made up his mind to make the aluminum alloy cylinder head of this engine, knowing that in the future, aluminum engines will become the mainstream configuration of engines.

Although the aluminum engine is not necessarily better than the gray cast iron engine, and even slightly deficient in some places, the key is that the aluminum engine is lighter than the cast iron engine, so as to achieve the purpose of reducing the weight of the body, so as to achieve the purpose of reducing fuel consumption.

Moreover, the heat dissipation of aluminum engines is better than that of cast iron engines, and the casting process is relatively simpler than that of cast iron engines, and the environmental protection pollution is small, so in the future, aluminum engines will become the mainstream of engines.

Now Ding Weizhong is engaged in the production process of the aluminum engine cylinder head, which can be regarded as a considerable level of technological research, after all, at present, the internationally famous automobile manufacturers have begun to study how to simplify the cost of aluminum engines, and the aluminum engine part of our Celestial Empire is just starting now.

So now Ding Weizhong began to study the processing technology of the aluminum alloy cylinder head, which can be regarded as a starting point for the future development of aluminum alloy engine processing technology!

Anyway, now the factory is also on the track in operation, and the design department led by Ding Weizhong has no new work recently, so it can work the processing of this aluminum alloy cylinder head.

During this time, Liu Xiaoliang often went to Ding Weizhong's processing technology department, where to watch the progress of the processing wages of this cylinder head.

The rest of the time, I kept going to Master Yang Dingwei to see the sand design of the engine block, because this engine is designed with aluminum alloy cylinder head.

Therefore, the cylinder head is aluminum alloy, and the cylinder body is gray cast iron, which will produce a certain friction problem, in order to solve the friction coefficient, as well as the expansion of the cylinder and so on, the sand design of the cylinder block, we must pay attention to the airtight surname and so on.

So here Master Yang Dingwei's molding sand molding is also very slow, Jin Xiaoqiang is not in a hurry, but Liu Xiaoliang is very anxious, he wants to see this engine for an interview as soon as possible, and he wants to be the first to test him.

He really wants to see it with his own eyes, and verify that this engine, after completion, can meet his design parameters, if it can really reach Jin Xiaoqiang's original design parameters, then the birth of this engine will undoubtedly be in front of the Celestial Empire's own brand car manufacturers, the first bombshell.

Even those joint venture brands, international manufacturers have to look at this engine with admiration.

Because from the cost, the surname can, this engine will undoubtedly become the king of the surname price ratio in the small displacement engine.

And this engine has unlimited potential for technical exploitation in the future, the cast iron material can be replaced with an aluminum engine, and then add the corresponding CVVT, or DVVT technology, or with the corresponding turbo.

In short, if this engine can be produced smoothly, and after a series of technical verification, it is fully qualified, then this engine will definitely become a fairly long-lived engine.

Several technical maniacs in the factory, in recent times, have been crazy about the drawings drawn by Jin Xiaoqiang, and everyone's division of labor is very clear, but the ultimate goal is very direct, that is, to turn the engine designed by Jin Xiaoqiang into reality from the drawings.

And Jin Xiaoqiang couldn't help but look at these technical maniacs, crazy about his design, but now it's time for him to take some time out to take care of his business.

Before you know it, the time has come to the 20th of March, and what is the most interesting news in recent times?

It is not that the United States has captured another city in Iraq, nor the fact that the American army has entered Baghdad, but a strange epidemic pneumonia that has just recently broken out in the Celestial Empire.

This pneumonia spreads through the air and some other ways, and the speed of transmission is very fast, and the infection is quite strong.

The earliest time this infectious disease began to appear was at the end of 2002, in Guangdong.

However, at that time, the health and epidemic prevention department in Guangdong publicized to the masses that this was not a big problem, and the epidemic was quickly brought under control.

During this period, the epidemic in Guangdong has actually been in the stage of spreading, and it was not long after that the epidemic began to spread to Yanjing, Shanghai and other big cities of the Celestial Empire.

When the epidemic began to appear in various places, the first thing that the local political axes at all levels did was not to announce the epidemic to the people and remind them of preventive measures, but to cover the lid through various means and strive to suppress the matter.

For what? Of course, it is for the red top, and GDP, and it is the face that our Celestial Empire people love the most!

As a result, God did not give face, and the epidemic did not continue to be suppressed, but intensified.

On February 9, the news that this virus was extremely powerful and spread rapidly began to spread in Guangdong, especially in the urban area of Guangzhou, and caused panic among a considerable number of people.

However, the authorities in Guangdong completely blocked the news, so the news in Guangdong did not spread until March in Yanjing, Shanghai, and other major cities across the country began to appear cases, this infectious disease called [***] type pneumonia, this began to attract the attention of the people across the country.

However, at this time, Nanyang has also fallen into an inexplicable state of panic, although Nanyang is not the hardest hit area, and the luck psychology of ordinary people is also very serious, but a few days ago Nanyang City found several carriers of the [***] virus, which made the spirit of Nanyang citizens nervous.

Now, in mid-March, the virus is intensifying across the country, and many provincial capitals across the country have announced the discovery of carriers of the virus.

And this epidemic has also aroused the idea of the United Nations Health Organization, and even on the occasion of the international conference of the United Nations, some people have proposed that the Celestial Empire, Hong Kong, and Taiwan should be listed as the hardest hit areas of the epidemic, and labeled as a travel warning.

Now the relevant departments and relevant leaders are hairy, and this disgrace has been thrown to the international community, which is the most intolerable thing.

At home, we can ask for money without shame, but in the international arena, we have always asked for face without money, and now we are embarrassed and disgraced internationally, which can make us preach a harmonious society every day, how can it be harmonious?

So after such a while, the mayor of Yanjing and the minister of health, their positions have begun to be precarious, and now local political officials have also begun to formulate plans on how to resist such an outbreak.

During this time, Nanyang successively reported that several people who returned to Nanyang from Yanjing and Guangdong carried such a virus, and these people have been sent to the hospital.

But because these people are returning to Nanyang by public transportation, it cannot be ruled out that other passengers on the bus have also been infected, so Nanyang City is currently in a very nervous state.

Some commodities and items have begun to rise in price quietly, especially in terms of some daily necessities, and in the current situation, it is obvious that there will be no good fruit to eat, and these two shops should be unlucky, they are speculating on some necessities of life.

The next day after the two supermarkets raised the price of some goods, one was ordered to suspend business for a month for rectification, and the other was directly fined 200,000 yuan.

At this time, Jin Xiaoqiang has been quietly observing, and watching the situation in Nanyang City, at present, the people of Nanyang City have a certain understanding of [***], and the official also attaches great importance to this epidemic.

But the current level of panic is not too serious, and the political axe is still quite strong in terms of price pressure, so now is not the time to act.

So he still has to wait, he remembers very well that the panic of Nanyang citizens about the epidemic was detonated in early April, and the period from mid-April to mid-April.

During that time, it was the most severe period of the epidemic, and many hospitals and medical structures were helpless against the epidemic, and the number of people who died of illness continued to be exposed every day, so the panic of the people at that time was very serious.

And at that time, an infected person who came back from Guangdong, did not obey the call of the political axe, and after returning home, he first went out to go shopping, and then felt that his body was wrong, and then hid directly at home, which eventually led to the entire community where he lived, three or four hundred people were infected, and the entire community was isolated.

Since then, there have been communities in Nanyang City that have been isolated by the entire community, and people have been sent to the hospital every day, and people have died every day because of [***].

That time was the peak time of panic among the citizens of Nanyang City, and it was also the best time for him Jin Xiaoqiang to make a move!
