Chapter 279 The first engine in the true sense, off the assembly line

The leader of Pengcheng really felt like being hit by a gold ingot while walking on the road.

The leaders of Pengcheng Prison came forward in person, and the leaders of Pengcheng City had no doubts about this matter. Communication with the prison.

The entire communication process was extremely smooth. After confirming the strength of Huateng Machinery Manufacturing Company, they were full of interest in this cooperation. For Pengcheng City, in this cooperation, apart from taking out a piece of land, they There is no need to do anything else, but you can harvest a large motorcycle manufacturer. Where can you find such a good thing?

Now that you have encountered it, you must firmly hold it in your hands!
It took less than a week for the three parties to reach a preliminary cooperation agreement.

It is said that blessings do not come together, and misfortunes never come singly. Zhang Qihang thinks this is wrong. Just after reaching an agreement with Pengcheng Prison and Pengcheng City, Ma Shaojun brought good news to Zhang Qihang. Several junior colleges, technical secondary schools, and vocational technical schools have expressed strong interest in the olive branch offered by Huateng Company, hoping to have a good talk with Zhang Qihang on the issue of cooperation. After hearing the news, the leaders of the Magic City highly appreciate Zhang Qihang's previous concept of community development, and hope to have a talk with Zhang Qihang...

It can be said that in the two months since the Chinese New Year, Zhang Qihang was either on a business trip, or on the way of a business trip, so busy that his feet didn't touch the ground.

Just when Zhang Qihang finished all this and was about to catch his breath, he received a call from Professor Xu...

"Xiao Zhang, it's done! It's done!"

Professor Xu's excitement and joy, even separated by thousands of kilometers of telephone lines, Zhang Qihang can still clearly feel it.

"It's done?" Zhang Qihang was taken aback for a moment, and then he became ecstatic: "Teacher, you mean..."

"That's right! It's the engine you designed," Professor Xu on the other end of the phone was very happy: "We just finished the first 10-hour simulation test. The performance of the engine is very good, and the internal wear is completely within the design indicators. Within the scope...Xiao Zhang, let me tell you, everyone is now full of confidence in the next stage of the test..."

Professor Xu is very happy, he is really happy.

Although when he first saw the design drawing provided by Zhang Qihang, he thought it was a fairly complete design, but seeing the drawing is one thing. As for when this engine can be mass-produced and finalized, he actually It’s not very optimistic. The reason is simple. There are strict testing standards for the engine. It’s not enough if the shape of the thing you make meets the requirements. It works normally within the range of load conditions, and there should be no wear beyond the index.

This creates a problem. The design life of a motorcycle is usually 10 kilometers, and the crankshaft rotates more than 10 billion revolutions in the engine. After so many revolutions, it is necessary to ensure that the wear is within the design standard. In this way, many requirements are put forward for the material of the crankshaft, machining accuracy, internal lubrication of the engine, oil passage design inside the crankshaft, machining accuracy and material of the bearing bush, etc., and the most important thing is that, After meeting the requirements in all aspects, the cost must be controlled and not too expensive...

Therefore, it is really not difficult to design an engine, but it is more difficult to make an engine that can be marketed, qualified, and has great competitiveness.

Before this, Professor Xu, Professor Li, Professor Wang and others were not optimistic, but it was unexpected that during the entire research and development process, Zhang Qihang would always be able to give solutions to many problems, so that from The school officially opened on the 20th of the first month and now, in less than two months, the School of Automotive Engineering has not only produced a batch of 20 prototypes, but all 20 prototypes have passed the first stage of testing. You said, Could Professor Xu be unhappy?
"Really? That would be wonderful."

Although Zhang Qihang actually participated in the research and development of this engine remotely, he communicated with Professor Xu and other professors through phone calls and faxes about many matters and problems. Zhang Qihang is still very happy about the news.

Zhang Qihang was happy, and Professor Xu was naturally even happier. He said with a smile: "Before the project started, I thought that everything would be smooth if the development and calibration of this engine could be completed by the end of this year, but according to the current progress trend, It is estimated that by this summer, the full process and full element development of this engine will be completed."

"I'm a little more optimistic than you. I think the development of this engine should not be completed by summer."

"Really? That would be even better," Professor Xu said, instead of getting angry, he became even happier: "By the way, after the development of this engine is completed, do you have a new engine development plan?"

Through the cooperation with Huateng, the professors, teachers and graduate students of the School of Automotive Engineering have tasted the sweetness: not only can they get money, but they can also use this opportunity to practice their skills. Where can such a good thing be found?It is also because of this that Professor Xu took the initiative to ask about the next development plan before the entire development process of this engine has been fully completed.

"Yes," Zhang Qihang didn't hide it. For this kind of thing, it's good to say hello in advance: "I am going to develop a 110cc engine based on the general structure of this 150cc engine."

"150CC?" Professor Xu was taken aback by Zhang Qihang's answer: "Not 125CC?"

This was beyond his expectation. Now domestic motorcycles have a displacement above 100CC is 125CC. Zhang Qihang’s 110CC is already amazing enough. In Professor Xu’s view, after completing this engine, Huateng The company's next engine should be 125CC. Unexpectedly, Zhang Qihang directly surpassed 125CC and started to work on 150CC.

"Yes," Zhang Qihang replied, without explaining why he did this, but continued: "Teacher, since the first stage of the test has passed, please send me two sets. Do something to match the body."

"No problem," Professor Xu nodded immediately without saying a word, "I'll arrange someone to send it to you later."
