Chapter 93 Ship Diesel Engine

  Two weeks later, the trial 190 diesel was taken off the production line.

  A 190-liter, 500-horsepower diesel engine is a big guy that requires professional moving equipment to lift it down. Placed outside, it's like a mobile home.

  Compared with the diesel engines previously produced by Jinan Power Machinery Factory, the 190 series has made significant progress in power and fuel consumption. Of course, there is still room for improvement, and after another 20 or even 30 years, the improved D-type and H-type of the 190 series will still be on sale, and Liu Qiu, as a big shot, is this 190 diesel engine.

  In the memory of Su City, after CNPC re-injected capital into Jinan Power Machinery Factory, they tried several new products, but the ultimate comeback was still the 190 diesel engine. Due to its reliable performance, it once forced foreign diesel engine brands onto the ropes, ultimately relying on bundled sales to survive.

  In terms of product design, Liu Qiu's 190 series diesel engine is a culmination of all achievements. The average effective pressure, power, speed, maximum burst pressure, cylinder bore stroke ratio, minimum oil consumption rate under partial load, and other indicators are all improved to varying degrees compared to similar products. What's more difficult to achieve is that he also considered the need for future improvements and spent a lot of effort making reserved space. This is the fundamental reason why the 190 series has been popular for 30 years.

  Although Liu's later works were more advanced, there was never another perfect work like "190".

  Su Cheng thought to himself: The 3 years of unemployment experience may have made his life difficult, but it had also tempered his spirit and body. Successful designers don't have 3 years to spend on designing, 3 years to carefully refine and make tiny improvements.

  Just hope, minus a year or more of accumulation, Liu Qiu's 190 series. Don't have too many changes.

  "Director Su? Testing the machine?" Chen Zuonian called out. He was still the director of Jinan Power Machinery Factory, while the owner of the factory, Su Cheng, had become Director Su.

  "Start the machine." Su Cheng gathered his spirits and watched as the diesel engine roared to life.

  A deafening roar. Exhilarating.

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

  After a while, Su Cheng asked: "How is it?"

  Liu Qiu rubbed his messy hair and took two steps back, saying: "The situation is very good, if it goes through. If we work overtime to produce, we can manufacture 1,000 units this year."

  "Oh, let me take a look at the blueprint." Su Cheng only understood the surface of it. Let Liu Qiu explain it to him.

  Although there is still a long way to go before becoming a great master, Liu Qiu is very experienced in explaining his own works.

  Su Cheng saw that he had already considered leaving space, so he nodded secretly, and the details could be used in the second or third generation of models, no need to rush.

  After all, they had produced more than 190 diesel engines a year in advance.

  "What's your idea for improving diesel engines next?" Su Cheng asked Liu Qiu directly.

  "I think that increasing power is the top priority...". Liu Qiuzhong puffed out his chest, and spoke several sentences very clearly, obviously having prepared them in advance.

  If he combed his hair a bit, his image might be better.

  "Power is indeed a problem, 500 horsepower is a bit less. However, diesel engines are not easy to sell now." Su Cheng didn't want to discourage Liu Qiu's enthusiasm, so he said: "Expanding the use of diesel engines is more important than producing them, you need to pay attention to this."

  "Extended use?"

  "The diesel engines we produce now are mainly used in construction sites and small power plants. Nowadays, each oil field is waiting to be divided, and large orders have stopped coming in, so we can't count on them. The remaining coal mines and metal mines use very few mining vehicles, and generally won't buy 190 diesel engines either. So, you need to consider several improved models of diesel engines, to make them suitable for more places."

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

  He is doing product design, not industrial design, and truly doesn't care about things like purpose.

  "How about the boat? The boat uses a diesel engine. Now coastal fishing boats are making a lot of money, and transportation is also lucrative. We provide them with better and cheaper diesel engines, and sales will definitely be good." Su Cheng found one of the overall assembly drawings, drew two lines with his fingernail, and said: "The main structure such as cylinder diameter, stroke, and cylinder center distance does not need to be changed, and the connecting rod, crankshaft, piston, etc. are also the same. However, the lubrication system and oil pan need to be modified to prevent oil spills or oil pump suction when shaking at sea. The intake and exhaust systems and cooling systems should also be redone to adapt to the ship's environment..."

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

  Before Suzhou came, he had done his homework. The ship's diesel engine is an important direction for the development of diesel engines. China has very few ships of its own, especially since the 1970s, and the total tonnage of Chinese ships has not even surpassed that of Hong Kong shipping magnate Yu Gang alone. But this phenomenon will change very quickly.

  China needs inland vessels and coastal fishing boats first, then heavy cargo ships and specialized ships.

  Just in time for diesel engine improvements.

  Su Cheng briefly stated his idea, and Chen Zuo listened with a learning attitude, asking: "Then who should we find to buy the diesel engine?"

  "Shipyard, even private fishermen, whoever can take out 50,000 yuan, can take away our diesel engine."

  "500,000 yuan? Our costs are more than 500,000 yuan." Liu Qiu jumped up.

  Su Cheng suppressed him, saying: "I've calculated with someone, the material cost is about 500,000 yuan. The current problem is that our production cost is too high, we need to find a way to reduce costs, and cannot have too high a price."

  "We used to sell for 1.5 million." Liu Qiu muttered.

  "Maybe in two more years, we can still sell for 150,000. Now it's not possible." Su Cheng thought to himself that the cost of diesel engines would have dropped again and again in the future. The only place where prices remain unchanged for 10 or 20 years is China. Enjoyment has come to an end, and now it's time to pay back debts.

  He raised his chin and asked, "How long will it take you to convert the boat to a diesel engine?"

  "It's been several months." Liu Qiu's enthusiasm was not high, and he asked, "Won't the ordinary diesel engine be produced anymore?"

  "Production is determined by sales volume." Su Cheng knew that ordinary diesel engines would not have any sales volume within a year. It was unrealistic to rely on the soon-to-be-abolished Petroleum Department or the China National Petroleum Corporation, which had yet to take power.

  Chen Zuo was a bit apprehensive, they had been out of the market for two or three years. In the past, it was also a planned economic operation. For the market economy, there is an innate fear.

  Liu Qiu said two more sentences, and they were all murmured.

  Su Cheng only then realized that he had hurt Liu Qiu's confidence. He couldn't help but comfort him, thinking: A future big shot. Who would have thought that this carefree person is actually a fragile young man... Hmm, a fragile middle-aged man.

  Liu Qiu stroked his messy hair, saying unhappily: "Director Su, you're the boss, I'll listen to you, but this diesel engine of mine has no design problems at all. As long as it's produced, there won't be any sales worries... We should still go all out in production."

  Two years later, the situation may be like this. Su Cheng shook his head secretly: no orders for oil extraction systems. Producing 1,000 diesel engines per year is even more of a loss than giving away 200 oil extractors for free.

  But this kind of argument about the market is pointless and will not get an accurate answer.

  Su Cheng then shifted his gaze to the blueprint and said, "You just said that the design no longer has any problems?"

  He suddenly remembered a classic mistake.

  Liu Qiu was taken aback and said stiffly, "Not bad."

  Su Cheng pulled out a draft paper, pointed to the right side and asked: "How does this explain?"

  "This is a safety protection device." Liu Qiu looked at it twice and said, "This is to prevent the oil pressure from being too low, and it also has the function of automatic parking in case of overspeed. In addition, when the oil temperature is high or the water temperature is high, it will automatically alarm. There is a butterfly valve on the intake pipe of the diesel engine. Once an emergency stop is made, closing the butterfly valve cuts off the air."

  "However, closing the butterfly valve, the remaining air will cause a change in pressure inside the cylinder body. Doesn't this piping need to withstand the risk of backflow?"

  Liu Qiu looked puzzled, her head spinning for a moment before she let out a soft "ah".

  This is a classic mistake on the 190, which occasionally occurs but is always misunderstood by users as their own operational error. Later after release, all the tens of thousands of diesel engines in use underwent a massive replacement of parts, and Su City had also witnessed it.

  Liu Qiu's entire head was bowed over the blueprint, no longer caring whether he was working at full capacity or not.

  Chen Zunian thought of Su Cheng's promise of "200 million yuan" to Director Ding at the banquet that day, and his heart itched but he didn't dare ask.

  Jinan Power Machinery Factory is a wholly-owned subsidiary of Suzhou City. The investment must be invested, but Chen Zuyu is not sure how much money Suzhou City has.

  Delayed for two days, Su Cheng saw that production was back on track and returned directly to Dongying. Chen Zuyan had no choice but to swallow his words and go back as well.

  He is actually quite satisfied with the current situation, although half of the workers were sent to Dongying to produce diesel engines, and only half of the people can work in Jinan, but compared to being laid off and living on subsidies, it's much better.

  Su Cheng returned to Dongying, but fell into a life of luxury and indulgence.

  Last year, he was just a university student with a Peking University title and had no chance to receive or initiate invitations.

  Nowadays, identities are quite different.

  Apart from the cadres still running around in Beijing, all the big and small heads of Shengli Oilfield have already known about Su Cheng, as well as Dahua Industry which supplies goods to foreigners.

  Those who can barely pull some connections will try to ask Su Cheng out. Among them, the main ones are office directors like Wei Kong and refinery factory heads.

  Su Cheng had never experienced such a scene before, getting drunk every day was inevitable. Fortunately, he had built up his tolerance and could drink a liter and a half of Maotai without immediately collapsing...

  Moreover, being able to eat and drink well in the 80s is already a pretty good life. Su Cheng is a bachelor, occasionally he can take Shu Lan out for a stroll, it's already something to be thankful for the society's tolerance, as for letting others cook meals, don't even think about it, it's "unacceptable"!

  Things like steak, no matter how much you eat, will eventually get tired of it. However, in the oil field cafeteria, one or two famous chefs would always emerge, with a salary of around 100 yuan, making dishes worth 30 yuan per plate - this salary is already very high domestically.

  The host knew that Su Cheng liked good food, so he casually found a new chef to borrow. From Oil Extraction Plant 1 to Oil Extraction Plant 10, Su Cheng had almost eaten his way through Lu, Chuan, Yue, Min, Su, Zhe, Xiang and Wan...

  On this day, the director of Oil Extraction Plant 2, Qu Guoda, had just sat down when his subordinates rushed in.

  "Less oil." The newcomer only said one sentence, and Qu Guoda rushed out, muttering to himself: "These oil-wasting bastards, can't even get through the year properly."
