"The car shell and accessories have been shipped, and the difficulty now is which engine does Donglin use for the car?" Zhao Gang said.

"With the V28 engine, it has six cylinders that start quickly. Yu Zeyang said.

"No, now that oil prices have risen sharply, car owners prefer fuel-efficient engines. Quality control Xu Qian said.

"But the fuel-efficient engine, the speed of the car is slow, the gear is slow, and now people like to live a fast-paced life. Yu Zeyang said.

"It's so fuel-hungry that you can't afford to buy a car and have no money to refuel, right?" Mr. Xu said.

"Now the state attaches great importance to environmentally friendly cars, and the state has subsidies for environmentally friendly small-displacement cars, and environmentally friendly small-displacement engines are applied. Zhao Zhuo said.

"Environmentally-friendly cars, this is indeed the trend of future development, do we have environmentally friendly engines?" Zhao Gang asked.

"Chairman, no. The assistant looked through the file and said.

"Since there is none, let's use the U4070 engine, which is fuel-efficient and fast, suitable for office workers. Xu Qian said.

"No, we will use it as soon as we produce cars, can we open up the market?" Yu Zeyang objected.

"I don't feel like I can use it just then, it's just—" Zhao Zhuo said.

"Or we're going to buy an eco-friendly engine. The assistant said.

"Donglin is a company that manufactures engines, and now it is still going to buy it, won't it be ridiculed. Yu Zeyang said.

"The engine used to be our strength, but now it's our weakness. Zhao Gang said.

"If we don't have a high-performance engine, how can we compete with those big cars. The assistant said.

"The 1,000 car shells and accessories ordered by the company will arrive next week, and the company's order is almost finished. Zhao Ya said.

"I was able to design an engine that was environmentally friendly and fast. Yun Lin said.

"How much time do you want, we're running out of time. Zhao Gang asked.

"A week. After Yun Lin answered, the audience looked at him in amazement.

"Yunlin, you are really sure. Zhao Gang asked, Yun Lin nodded, Zhao Gang was very excited.

"Okay, about the new engine will be handed over to Xu Yunlin, and next week Donglin will start car production. At the end of the meeting, Zhao Zhuo came over and said:

"Yunlin, you really have this confidence, if you can't design it in a week, your future in Donglin will not be guaranteed. Yun Lin smiled and walked out of the conference hall.

Yun Lin returned to the apartment and called home. "Hey, Yunlin, how are you doing?" asked my father.

"Okay, Dad, I'm in charge now, and I've been appreciated by the chairman, and I get along well with my colleagues. Yun Lin said.

"Well, I know my son can do a good job. His father was happy for him, too.

"Dad, do you remember the blueprint I showed you?"

"Remember, what's wrong?"

"Donglin now produces cars, but there is a lack of engines, and my environmentally friendly engine is just right for use. ”

"Yes, try harder. ”

"I will, Dad, you have to pay attention to your body and be careful when driving. ”

"Hmm. The father and son ended the conversation, Yun Lin opened the design drawing, looked at it carefully, called Yu Zeyang from time to time to ask about the engine parts, and kept searching for engine information on the computer.

The next day, just after dawn, he came to the company and began to assemble according to the design drawings. Yun Lin encountered a lot of problems in the process of assembly, and in order to solve these problems, he stayed up for a few nights, but a problem grew there like a spell, and Yun Lin just couldn't get over. Yun Lin thought of giving up, thinking that this setting would not have much impact on the start of the car, but he was a person who pursued perfection, and if he didn't set it up, he would never deliver it. Besides, this is a matter related to the safety of life, and Yunlin does not dare to slack off. As time passed, the supervisor saw that Yunlin was still doing experiments, and they all thought that Yunlin couldn't hand over the samples, and they were all worried about him. On the last night, Yun Lin racked his brains to do experiments, but the engine settings had not yet broken through, and Yun Lin almost collapsed.

Yun Lin sat on the ground, and suddenly remembered Li Ting, if she was so good here, Li Ting always liked to say, I believe in you, but at this moment Yun Lin didn't believe that he could break through this setting. He thought of tomorrow's board of directors, and he could not hand over the samples, and he might be dishonored and forced to resign. He took out the butterfly jade on his neck, the jade was very crystal clear, like a flying butterfly, for some reason, every time Yun Lin saw the butterfly jade, he could feel Li Ting's figure, what was she doing at the moment? Suddenly the butterfly jade flashed, and a ray of light emanated from the jade, as if to guide Yun Lin, Yun Lin was very surprised, followed this light, walked in front of the engine, the light flashed a few times on the engine, and then disappeared. Yun Lin was stunned, he thought about this light, is he telling himself something? Yun Lin followed the traces left by the light, carefully searched, and finally broke through this setting. Yun Lin waved his fist, he didn't expect that the butterfly jade had such magic power and could help him solve the difficulty, he kissed the butterfly jade.

Yun Lin rubbed his eyes, but he came to the conference hall in good spirits, the directors and directors came, Zhao Gang also walked into the hall, Yun Lin unveiled the engine, and a delicate engine stood on the table. Yun Lin exhaled and said: "This engine is designed by me to transform the fourth generation of Mercedes-Benz, and it is an environmentally friendly engine. It is an in-line 6-cylinder engine, and although it has two more cylinders than the conventional engine, the engine is better balanced and less vibrating when it starts. I designed an intake device that uses a computer to control the opening and closing of the intake valve according to the engine speed, throttle opening amplitude and driving conditions, which improves the intake efficiency. The engine provides abundant sweep torque output, which improves fuel efficiency, greatly reduces the emission of harmful gases, and is more environmentally friendly. By improving the cylinder head, running and bore of the cylinder block, I have made its fuel consumption almost the same as that of a 4-cylinder engine, or even lower than that of a 4-cylinder engine. Yun Lin looked at the directors and directors who were out of his mind. With a sigh of relief, he said:

"It is smaller, more delicate and more compact than our previous engines, and the body is the skeleton that makes up the engine, and all the main parts and accessories of the engine are installed inside and outside to withstand various loads. Therefore, the body must have sufficient strength and rigidity, I use the cylinder block and upper crankcase of the water-cooled engine to cast as a whole, and cast many stiffeners, cooling water channels and lubricating oil channels inside the cylinder block. In order to reduce the height of the engine, I tilted the engine at an angle, and the combustion table adopts a hemispherical combustion chamber, and the spark plug is arranged in the center of the combustion chamber, so the flame stroke is short, so the combustion efficiency is high, so that the heat dissipation is less and the thermal efficiency is high. The bottom shell is equipped with an oil stabilizing baffle to prevent the oil level from fluctuating too much when the car is bumped. The cylinder head is made of aluminum-alloy, which is more conducive to heat conduction, improves the compression ratio, and makes the piston more efficient and smoother throughout the engine, so that the starting and shifting times are shorter. After Yun Lin finished speaking, the conference hall resounded with long-lasting applause. Zhao Gang came over and said, "Yunlin, it's hard work." "Yunlin is also pleased to be recognized by the directors and directors.

When he returned to the office, Zeng Zhichao was very attentive to him and actually poured him a glass of water. He smiled and said, "Director Xu, I said something bad before, I'm sorry for you, I hope you forgive me." Yun Lin was surprised by his title, but he was able to thaw with himself, Yun Lin was still very happy, and said with a smile: "I also have something wrong, and I hope you can forgive me." The two reconciled as before, Zeng Zhichao asked about the company's production of cars, and Yunlin said in detail.

Yun Lin returned to the apartment, feeling like his whole body was falling apart, he walked to the mirror, is this himself? He knew he had to rest, for he had not slept for days, and he had fallen on his bed like a warrior who had died a heroic death. The sea breeze blew gently, blowing his body and blowing away the exhaustion for him.
