reborn industrial empire

Modern 4-cylinder engines generally have four valves per cylinder, 2 intakes, 2 exhausts, a camshaft, and a rocker arm.

And this seemingly simple camshaft is the key to how much horsepower an engine can eventually burst out. It allows the engine to obtain high torque at low speeds, and allows the engine to produce greater power when running at high speeds.

of power.

High power means that the car's speed is fast enough, and high torque means that the car's speed is fast enough. These two data are of very important significance to modern cars.

The VVT ​​technology that Jin Xiaoqiang wants to experiment today is actually to change the design of the camshaft, integrating a camshaft that controls low speed and a camshaft that controls high speed into one camshaft.

Then the operation of the camshaft is controlled according to the driving computer ECU, thereby achieving a motion system that controls the valve timing and valve lift, so that the air and gasoline achieve the best combustion ratio, and the engine obtains greater combustion efficiency.

Explode more power.

However, the engine that Jin Xiaoqiang and the others are going to test today is the civilian version of the 4g63 engine. This engine is of SOHC configuration, which means that it only needs one camshaft on the engine.

When machining a camshaft, generally the material required for the camshaft is a special cast iron material. Jin Xiaoqiang’s factory has such a material, although it is quite different from the camshaft materials used by Toyota, Honda, and Volkswagen.

But for now, if it is only for experimental purposes, it is enough.

Moreover, the tools needed for machining, such as milling machines, drilling machines, etc., are also readily available in their gear factory. Although the machines used are all second-hand machines bought from Japan, the accuracy is still acceptable. It is enough to process a camshaft.

There's more than enough rubbing.

In terms of processing, Jin Xiaoqiang asked Liu Xiaoliang to talk to the machine tool masters at home, and then the masters started processing based on Liu Xiaoliang's description and the drawings he brought.

By evening, a total of three camshafts had been processed over there. Jin Xiaoqiang took these camshafts over and measured them in his hands.

It seems that the processing is quite acceptable, because now they are just asking for use and verifying his theory first, so there are no special requirements for the industry and materials of these camshafts.

But if mass production is required in the future, the process must be standardized and strive for excellence.

After Jin Xiaoqiang and Liu Xiaoliang removed the camshaft from the original engine, they replaced it with the processed camshaft, and then started testing the data.

During the operation of the engine, they constantly adjust the data inside the ECU, allowing the trip computer to control the operation of the camshaft in conjunction with data from sensors in other parts.

This is a very boring and tedious job. In fact, Jin Xiaoqiang has the data he memorized in his previous life. However, because this engine is not the same engine that he tinkered with in his previous life, he can only let Liu Xiaoliang work on this engine now.

Slowly toss the top.

Once you have verified your theory, you can start to modify it. First, you need to change the single overhead camshaft arrangement of Sohc to the double overhead camshaft arrangement of Dohc. Then follow today's procedure to modify the camshaft and conduct testing.

, record the data, and then adjust.

Until this engine can be adjusted to optimally control the valve timing and stroke time in conjunction with other data, until these data are clear.

Then let the ECU record such data, and then match it with the transmission of the power output part, with the manual transmission, then with the automatic transmission, etc.

Therefore, this series of experiments will be a very long process. Without three to five months to half a year of non-stop testing time, it is simply impossible to complete.

Moreover, such an experiment would require an investment of time and financial resources, which would be quite a headache.

But now that Liu Xiaoliang, a technology-savvy maniac, was watching over here, Jin Xiaoqiang felt relieved.

Now he can only keep an eye on it here alone. His first priority is to get money first. After he gets enough money, he can set up a company, then recruit people, and then help Liu Xiaoliang...

The two of them continued the experiment until about ten o'clock in the evening. Jin Xiaoqiang glanced at Liu Xiaoliang and saw that this guy had no intention of leaving at all. He was still sitting there and watching the various data transmitted to the computer by the ECU with relish.

There was no other way, Jin Xiaoqiang could only ask someone to arrange a place for Liu Xiaoliang to live in the factory, then said hello to him and went back.

From now on, he won't need to come here to keep an eye on the experiments. With a technical geek like Liu Xiaoliang, that's probably enough.

...........

When Jin Xiaoqiang returned home, Jin Guozhu and Li Shulan hadn't come back yet. These two guys had been out all day running about the land auction, and they haven't come back yet.

Jin Xiaoqiang dealt with it randomly by himself and went to bed.

When they came together the next morning, Jin Xiaoqiang found that his mother had already prepared breakfast outside, and his father was sitting in front of the table slowly eating breakfast.

Li Shulan saw Jin Xiaoqiang coming out of the room and quickly served him a bowl of porridge. Jin Xiaoqiang took the porridge and sat at the dining table and started eating.

After just a few bites, Jin Xiaoqiang suddenly remembered the land auction, so he hurriedly asked Jin Guozhu.

"Dad, how are you doing with the land auction in Xinghe Village?"

"Well, your mother and I were running around here yesterday, hehe! Guess what happened?"

As soon as Jin Guozhu heard Jin Xiaoqiang's question, he started to explain it to him. After just a few sentences, he couldn't help but burst into laughter. Apparently they encountered something very good yesterday. Jin Xiaoqiang guessed that someone couldn't sit still and took the lead.

Some very good conditions were given.

"What's wrong? Does anyone want to take action so soon?"

Jin Xiaoqiang had already made a guess in his mind, but in order to cooperate with his father, he deliberately asked a question out loud.

"Hey, don't you know how much money someone paid for just the approximately 2,000 acres of land in my hand near the urban area, at the far end of Xinghe Village?"

In his previous life, Jin Xiaoqiang probably went to Xinghe Village after that. He knew the place that Jin Guozhu was talking about now.

The terrain of that land is relatively flat, and it is just across the Daling River from the urban area of ​​Nanyang City, so the geographical conditions can be said to be quite superior.

If you want to build a development zone or real estate, it will undoubtedly be a very good place. After all, it is close to the city and there are water sources around it.

"How much is it?"

Jin Xiaoqiang was also somewhat whetted by his father.

"Hey, someone quoted me 500 million yuan yesterday. For that piece of land alone, they quoted me 500 million yuan!"

Jin Guozhu felt a little happy when he mentioned the price quoted by the person yesterday. In fact, he originally spent about 200 million to acquire that piece of land.

Of course, a lot of that land used to be cultivated by farmers. In order to change the land use rights, he spent a lot of money. In addition to buying the land, he spent a total of no less than 200 million inside and outside. Now it has changed hands.

Earned twice as much.

"Then do you agree?"

When Jin Xiaoqiang heard this quotation, his heart was pounding. If he could buy this land, then the 500 million yuan his father had borrowed from the bank to buy the land would be enough, so there was no need to worry.

"Hey, I was also moved at the time, but I didn't agree to him. I quoted 700 million, but my bottom price was at least 500 million or 600 million. I planned to let him go for a day or two.

Let’s see if they can scream a little higher then.”

Jin Guozhu is an old business man, and he knows how to play hard to get.

"Hehe, that's fine, but don't delay it for too long. It's best not to go beyond the end of March, otherwise, I'm afraid things will change if it's too late!"

Thinking about the upcoming SARS, Jin Xiaoqiang still hopes that his father will keep the money in his pocket to avoid being delayed by SARS. If these lands are really lost, there will be no place to cry.

"Well, I guess it will be soon. They will definitely contact me again today. If their attitude is relaxed today, then I will take action. My other two pieces of land have just been released, and people are already contacting me.

As for me! Hehe! It seems that these people really don’t know about the Xie family. We really have to take action quickly. My son, my father believes in you this time! If the old Xie family survives by then, my father won’t blame you.

."

Jin Guozhu's words were a bit sour. In fact, in his heart, he really didn't want Xie Shengli to fall. After all, if Xie Shengli was in office, the plan to develop Xinghe Village could continue, and he could still make more money.

money.

"Hey! Dad, don't worry! My news is definitely accurate. Xie Shengli's family won't be able to survive this long."

Jin Xiaoqiang quickly gave the old man another reassurance to prevent him from hesitating.

"By the way, someone from Shenhua Group came to me yesterday and said that he wanted to exchange land with me. He wanted to take a piece of their coal mine, magnesium ore, and iron ore in Xigangzi, which is almost one square meter in total.

The mining area of ​​about 10 kilometers, plus the mining operation rights, will exchange for a piece of land in my hand. The location of that piece of land is great. It happens to be in the center of Xinghe Village. I guess even if it is a development zone, what will happen?

It can definitely become the city center of the development zone. Do these people think I am a fool? How much is the ruined mine over there in Xigangzi worth now? The mining area of ​​more than one square kilometer is completely inhabited.

Ordinary people are not willing to go to the rare mountainous areas or hilly areas, even for farming, and the ores there are of low grade. Do these people really think I am a stupid old hater? It is infuriating to think about it, so I just

They gave it back."

Jin Guozhu seemed to have remembered something, and now he said to Jin Xiaoqiang angrily.
