Two weeks later, the 190 diesel engine for the test was moved off the production line.

The 190-liter, 500-horsepower diesel engine is a very large guy and requires professional transportation equipment to lift it down. It is like a mobile room outside.

Compared with the diesel engines produced by Jinan Power Machinery Factory before, the 190 series has made considerable progress in power and energy consumption. Of course, it still has a lot of room for improvement. In the next 20 years or even 30 years, the improved D and H types of the 190 series will still be sold. As a big shot, Liu Qiu is this 190 diesel engine.

In Sucheng's memory, after CNPC reinjected funds from Jinan Power Machinery Factory, they had tried several new products, but the Jedi counterattack was still the 190 diesel engine. Due to its reliable performance, it once forced foreign diesel engine brands to Liangshan, and eventually could only survive by bundled sales.

As for product design, Liu Qiu's 190 series diesel engine is a masterpiece, with average effective pressure, power, speed, maximum burst pressure, cylinder bore stroke ratio, minimum fuel consumption rate of part load, and other indicators. It has been improved by similar products. The most rare thing is that he also considered the future improvement needs and spent a lot of energy to make reserved space. This is the fundamental reason why the 190 series can be sold and improved for 30 years.

Although Liu Qiu's later works are more advanced, there is no perfect work like 190.

Su Cheng thought to himself: Three years of laid-off experience may have made his life difficult, but it has tempered his spirit and body. After success, the designer has three years to design, and three years to think about it and make some improvements.

I just hope that after more than a year of accumulation, Liu Qiu’s 190 series will not change much.

"Dr. Su? Test the machine?" Chen Zunian called out. He was still the director of Jinan Power Machinery Factory, and the owner of the factory, Su Cheng became Director Su.

"Test the machine." Su Cheng restrained his spirit and watched the diesel engine start.

The dull roar is exciting.

Liu Qiu and others stood in front of the instrument and monitored various data.

After a while, Su Cheng asked, "How is the situation?"

Liu Qiu rubbed his messy hair and took two steps back. He said: "The situation is very good. If we pass. If we work overtime, we can make 1,000 units this year."

"Oh, show me the drawings." Su Cheng only knew the basics. So he asked Liu Qiu to explain to him.

Although Daniu is still a decade away, Liu Qiu is still very experienced in explaining his works.

Seeing that he had considered the reserved space, Su Cheng nodded secretly, and the details could be used on the second-generation and third-generation models, so there is no need to worry.

After all, they have produced 190 diesel engines more than a year ahead of schedule.

"Next, what do you think about the improvement of diesel engines?" Su Cheng asked Liu Qiu directly.

"I think that increasing power is the primary concern..." Liu Qiu raised his head and said a few words very clearly, obviously he had already prepared it.

If he had combed his hair slightly, his image might have been better.

"Power is indeed a problem, 500 horsepower is indeed a little less. However, diesel engines are not easy to sell now." Su Cheng did not want to dampen Liu Qiu's enthusiasm, and said, "Expanding the use of diesel engines is more important than producing diesel engines. Here, you need to pay more attention."

“Expand use?”

"The diesel engines we produce now are all used on construction sites and small power plants. Nowadays, each oil field is waiting to separate, and the big orders have stopped. You can't count on them. The remaining coal mines and metal mines have too little use of industrial and mining vehicles, and generally you won't buy a 190-yuan diesel engine. So, you have to consider several improved diesel engines so that the diesel engine can be suitable for more places."

Liu Qiu was stunned and asked, "Where else can this thing be used?"

He is a product design, not an industrial design, and he really doesn't care about uses and other things.

"How about the ship? Marine diesel engines. Now the coastal fishing boats are very profitable and transportation is also very profitable. We provide them with better and cheaper diesel engines, and the sales must be good." Sucheng found one of the assembly drawings and scratched two with his fingernails, saying: "The main structures such as cylinder bore, stroke, cylinder center distance do not need to be changed. The same is true for connecting rods, crankshafts, pistons, etc. However, the lubrication system and oil pan should be changed to avoid the oil spillover or the oil pump sucking in the air when shaking at sea. The intake and exhaust and cooling systems are also remade to adapt to the environment on the ship..."

Liu Qiu looked carefully, holding a pen in his hand, and scribbling on the notebook.

Before Su Cheng came, he did his homework. Marine diesel engines are an important direction for the development of diesel engines. China has few ships, especially since the 1970s, the ship tonnage of all China is not as high as that of Hong Kong ship king Pao Yugang. But this phenomenon will change very quickly.

What China needs first are inland boats and offshore fishing boats, and then, heavy-duty cargo ships and professional ships.

Just fit the improvement of diesel engines.

Su Cheng briefly said his thoughts. Chen Zunian listened with a learning attitude and asked, "Who should we buy a diesel engine?"

"Whirlpools, even private fishermen, whoever can afford 50,000 yuan can take our diesel engines."

"50,000 yuan? Our cost is more than 50,000 yuan." Liu Qiu jumped up.

Su Cheng suppressed him and said, "I have found someone to calculate the cost of the material, which is 50,000 yuan. The problem now is that our production cost is too high. We need to find a way to reduce the cost, not too high."

"We used to sell 150,000 yuan." Liu Qiu muttered.

"Maybe in two years, we can still sell 150,000 yuan, but now it won't work." Su Cheng thought to himself that the cost of diesel engines in the future has long fallen and then fallen. The price remains unchanged for 10 and 20 years, that is, China, enjoyment is over, and it is time to pay off its debts.

He raised his chin and asked, "How long will it take for you to change the marine diesel engine?"

"It will take several months." Liu Qiu was not very interested and asked, "Will the ordinary diesel engine not be produced?"

"Production is determined based on sales." Sucheng knew that ordinary diesel engines would not have any sales within one year. It is unrealistic to expect the oil ministry that is about to be revoked or PetroChina that has not yet taken control.

Chen Zunian was a little nervous. They had been away from the market for two or three years. They used to be the business method of planned economy. They were born with fear of the market economy.

After saying a few more words, Liu Qiu was depressed.

Su Cheng realized that he had hit Liu Qiu's confidence. He couldn't help but comfort him, thinking: The future big bull seems to care about nothing. Who would have thought that he is also a fragile young man now...well, a fragile middle-aged man.

Liu Qiu touched his messy hair and said unhappily: "Dr. Su, you are the boss, I listen to you, but my diesel engine has no problem designing it. As long as it is produced, you will not have to worry about no sales... We should still do our best to produce it."

Two years later, this may be the case. Su Cheng shook his head secretly: There is no order for oil system. Annual production of 1,000 diesel engines is much more loss than if I gave 200 oil pumps for free.

However, this kind of argument about the market is boring and will not get an accurate answer.

Su Cheng then set his eyes on the drawings and said, "You just said that there is no problem with the design?"

He suddenly remembered a classic mistake.

Liu Qiu was confused and said "yes" with a tough look.

Su Cheng pulled a drawing, clicked on the right, and asked, "How to explain it here?"

"This is a safety protection device." Liu Qiu glanced at it and looked up and said, "This is to avoid too low oil pressure, and the function of automatic parking at speed is also designed. In addition, high oil temperature and high water temperature will also automatically alarm. There is a butterfly valve on the intake pipeline of the diesel engine. Once the butterfly valve is closed, the air will be cut off."

"However, closing the butterfly valve and the residual air will change the pressure of the cylinder. Wouldn't the pipeline here bear the risk of backflow?"

Liu Qiu looked puzzled and had a few twists in his head before he let out a "ah" softly.

This is a classic minor mistake on the 190s. It occasionally occurs, but users always misunderstood that it is their own misoperation. After the release, all the more than 10,000 diesel engines in use were replaced on a large scale, and Sucheng had also seen it.

Liu Qiu's whole head was on the drawings, and he no longer had to do his best to produce or not.

Chen Zunian thought about the "20 million yuan" promised by Su Cheng to Director Ding at the banquet that day, but he was itchy but he couldn't ask.

Jinan Power Machinery Factory is a wholly-owned company of Sucheng. You must invest money in it, but Chen Zunian is not sure how much money Sucheng has.

After two days of delay, Su Cheng saw that the production was on track, he returned to Dongying directly. Chen Zunian had to hold back his words.

He was actually quite satisfied with the current situation. Although half of the workers were sent to Dongying to produce diesel engines and only half could work in Jinan, it was much better than the fate of being laid off and receiving living expenses.

Su Cheng returned to Dongying, but fell into the wine pond and meat forest.

Last year, he was just a college student with the title of Peking University and had no chance to accept or initiate a banquet.

Nowadays, the identity is very different.

In addition to the cadres who are still in the Beijing running department, Shengli Oilfield's big and small minds already know Sucheng and Dahua Industry, which serves as suppliers to foreigners.

Those who can get a little bit of contact will try to make an appointment with Su Cheng. Among them, people like Wei Kong's office directors and oil production plant directors are mainly people.

Su Cheng had never been exposed to such a situation. He was so dizzy that he drank every day, but he couldn't go. Fortunately, he had practiced his alcohol tolerance and slowly drank one and a half pounds of Maotai, so he would not collapse immediately...

Moreover, being able to eat and drink in the 1980s was a good life. Su Cheng was a bachelor. He could occasionally pull Shulan to the road. He had to thank the society for his tolerance. He could make people cook and not think about it, and it was "never tolerated"!

If you eat too much steak, you will always get bored. However, in the canteen of the oil field, one or two famous dishes can always appear, and you can make famous dishes worth 30 yuan a plate. This salary is already very high in China.

Those who invite guests know that Sucheng likes delicious food. If you just look for it, you can borrow a new chef. Sucheng will eat from the first oil production plant to the ten oil production sites. Shandong, Sichuan, Guangdong, Fujian, Jiangsu, Zhejiang, Hunan, and Anhui are almost all...

On that day, as soon as Qu Guoda, the director of Oil Production Factory 2, sat down, his subordinates chased him in.

"There's less oil." The visitor said just one sentence, and Qu Guoda rushed out and cursed: "These gas mice have not had a good time in the year."
