Manufacturing Empire in the Valley

Chapter 319 The Perfect Work

Fang Dongping smiled and nodded: "That's good. No matter what you do, it's always right to be careful. This time, with the super carbon steel you invented as the foundation, our engine sample will definitely be famous all over the world!"

Niu Xiaoqiang said modestly: "The main reason is that Master's design plan is very good. With the technology you provide, we can be successful."

The engine Fang Dongping designed this time is really extraordinary, and its performance is even stronger than domestic military products.

To judge whether the performance of an engine is superior or not, it mainly depends on the following aspects:

The first is power.Power refers to horsepower, and horsepower is the power output of the engine at different speeds and different oil supply conditions.Generally speaking, in the case of the same fuel consumption, the engine with higher horsepower is more powerful.This is a hard indicator, and any engine will try to move closer to this indicator at the beginning of its design.

The next thing to look at is the maximum torque.The concept of torque is not very popular in China, and only professionals can understand it.

The unit of torque is Nm, which refers to the torque of the engine.For vehicles with the same transmission ratio, the larger the torque value, the stronger the power.

This concept seems to be the same as power, but it is actually different.Power should consider the factor of fuel consumption, while torque is more concerned with the power effect that the engine can display.It is not easy to combine the two. Without strong design technology and materials as support, it is not necessary to think about it.

Then look at the number of cylinders in the engine.To put it bluntly, the number and size of cylinders are directly related to the power of the engine.

For example, tractors, many tractor heads are horizontal bars, and the horsepower is only a dozen horsepower. No matter how to improve the performance, since it is only a single cylinder, the horsepower is also very limited.

Tank engines are different. They generally have twelve engine cylinders, and the cylinders are larger, so the engine is extremely powerful. It can support tanks weighing tens of tons and galloping at speeds of tens of kilometers per hour. , this is something that tractors cannot do anyway.

Then there is the compression ratio.The larger the value of the compression ratio, the better the combustion work of the engine, and the stronger the power of the engine at the same time.

At present, the best domestically produced diesel engine in this regard is the tank engine, with a compression ratio of ten to one.

This type of diesel engine was actually created by Fang Dongping. Without him, it would be impossible to design this engine in China.

How high is the compression ratio of the diesel engine that Fang Dongping is designing now?The answer is fifteen to one!From this point alone, this diesel engine has far surpassed the old model before, and it must have no rivals in China.

As for the situation in the international arena, since both of them don't know much about the level of foreign diesel engines, they are not very good at judging.

According to Fang Dongping's estimate, the performance parameters of the engine sample currently being produced can definitely reach the international second-rate standard, and may even be higher.

After all, foreign countries have been tinkering with the engine field for so many years. Whether it is design ability or manufacturing ability, their technical accumulation is extremely powerful. With a certain gap.

It is not terrible to have a gap, as long as you have the courage and perseverance to dare to catch up.Fang Dongping is most satisfied with taking Niu Xiaoqiang as a talented apprentice. He firmly believes that Niu Xiaoqiang can go further and climb higher than himself in the field of engines.

Fang Dongping even had an illusion that Niu Xiaoqiang was the savior sent by heaven to save him.Without the super carbon steel invented by Niu Xiaoqiang as his confidence, it would be impossible for him to turn the drawings into reality.Take the engine he designed this time as an example. If ordinary materials are used, it is estimated that the engine is very likely to explode, which is a big problem.

When the engine is running, the interior needs to withstand the test of high temperature and high pressure. Once the material cannot withstand the high temperature and high pressure, the cylinder will definitely explode, which means that the engine is considered useless.

The master and apprentice chatted aside for more than half an hour, both full of hope for the future.Just when they were chatting happily, Zhou Kai waved his hand on the operating table: "Xiaoqiang, the molten steel has reached the standard for being out of the furnace, and you are all ready for casting and cooling."

Niu Xiaoqiang agreed, and walked to the mold with Fang Dongping.Zhou Kai repeatedly confirmed with the two of them several times, until he was sure that the two were really ready, and then he operated the steelmaking furnace to carry out the dumping operation.

The hot molten steel flowed down the exit. Niu Xiaoqiang and Fang Dongping had already made full preparations, and there were no problems during pouring.

After the casting work was completed, the two immediately water-cooled the mold.When the mold cooled down, the three of them moved the mold to the cart together and rushed to the processing workshop of Yuyang Agricultural Machinery Factory.

In the next half month, Fang Dongping and Niu Xiaoqiang used grinding tools to finish the original parts.

Fang Dongping was very strict and did not allow any omissions. If it wasn't for this, the two of them wouldn't have spent half a month processing the spare parts.

Then there is the assembly of the engine.This process is difficult and difficult to say simple and simple.In the eyes of ordinary workers, it is naturally very difficult, but in the eyes of Fang Dongping, assembling the engine is simply a child's play.

Even though the difficulty of the work is already very simple for Fang Dongping, in order to achieve excellence, Fang Dongping is not sloppy at all. He repeatedly confirms and inspects every link and strives to do his best.

Two days later, the diesel engine, which Fang Dongping had devoted his life to, was finally completed.At the moment when the assembly work was completed, Fang Dongping surprisingly didn't cheer or even laugh.He looked at this perfect work with red eyes, and his face was full of extremely complicated expressions.

Niu Xiaoqiang knew why Master did this. To put it bluntly, it was actually very simple: Fang Dongping was lamenting his unbearable past.

During that unforgettable era, Fang Dongping wasted years and suffered unfair treatment.That was the golden time in his life, when he was at his most vigorous, and it ended up being wasted in vain.

If those things hadn't happened, Fang Dongping would undoubtedly have achieved higher achievements in the engine field, and the country's engine industry would have made great progress.But there are no ifs in this world, what has happened is impossible to change, and those wasted years are impossible to come back.

Fang Dongping was very unwilling, and also very sad and angry. The reason why he didn't want to go out of the mountain was because he couldn't get over the hurdle in his heart.He would rather stay in the remote valley of the concave mountain and wait to die, than hand over his technology to someone he doesn't like.

Fortunately, God opened his eyes and let him meet Niu Xiaoqiang.Niu Xiaoqiang saved his life and ideals, and found some comfort for his troubled first half of his life.
