On the engine test bench, an engine was rumbling, the turbocharger was whistling, and even some redness could be seen.

If you are familiar with it, as long as you listen to this sound, you will know that the speed of this engine has reached its maximum, and at this time, in front of the engine test bench, a watch is clicking and moving, in all kinds of roars, but it is even clearer.

This engine is a little different from ordinary engines, the normal engine has a water tank in the front, all of which are in the shape of a piece, and there is a rotating fan blade in front of the water tank.

This engine also has a fan blade in the front, but there is no water tank, and the fan blades are blown directly to the back, where it has been wrapped, and you can't see the internal situation, only the inclined cylinder heads on both sides.

It's an air-cooled diesel!

At this time, in front of the test bench, more than a dozen technicians were waiting nervously there, wearing the blue uniforms of the factory, and on the front of the uniforms, a small logo of the Beihua Diesel Engine Factory was written.

Beihua Diesel Engine Factory is not known to ordinary people now, even in the industry, it is not famous.

This factory was first started as the "542" project, as one of the key projects of the third-line construction during the "45th Five-Year Plan" period.

In that special era, it was also known that the Soviet Union in the north would push the rolling torrent of armor over at any time, and the country was even ready to lose half of the country to fight this war, and at the same time, a large number of factories must have been attacked by the other side first.

Therefore, all kinds of factories have to be transferred to the third line, and the Dongfeng plant was established under such a goal, and at the same time, there are many similar projects.

Beihua Diesel Engine Factory, which was established in the depths of the mountains, was also one of them, when the original project was set up to be very large, there was a general headquarters of the project, seven branches, but from the site selection to the present, it has been bumpy, the project has experienced four times of suspension and continuation, five times of withdrawal and merger.

It was not until now that the whole project was merged into Beihua Diesel Engine Factory, which specializes in the production of diesel engines.

Of course, this is also because of the self-improvement of the workers of Beihua Diesel Engine Factory, due to the long-term experience of intermittent construction, resulting in them do not have a stable environment for production and construction, but they carry forward the excellent style of slow construction of the project, adhere to the construction of infrastructure while trial production.

In the construction of the factory in these years, they have successively trial-produced V8-135 water-cooled diesel engines, micro-rotation armor-piercing projectiles, and trial-produced and mass-produced CY-750 light transport vehicles and other products.

Among them, the most eye-catching is that in the past few years, after the country introduced the 413 series air-cooled diesel engine production license of Deutz Company in Germany, this diesel engine was allocated to several domestic diesel engine factories for joint production, and Beihua Diesel Engine Factory, not waiting or relying on, also began the production of this diesel engine.

Up to now, this Deutz diesel engine has become the flagship product of Beihua Diesel Engine Factory, and up to now, more than 1,500 units have been produced, which is quite a good result.

So what's going on on this test bench?

Time passes little by little, and the mystery will eventually be revealed.

"A thousand hours, a thousand hours!" Finally, when the hands of the clock pointed to the long-awaited position, everyone present cheered.

Ye Qiming, director of Beihua Diesel Engine Factory, was excited: "Great, our products have passed the 1000-hour reliability full speed full load and maximum torque point working condition test, and the parts and components we produce ourselves on this diesel engine have exceeded 70%!" ”

As with other projects, after the introduction of technology, we first assemble the parts from abroad, assemble them ourselves as finished engines, and then slowly make our own parts to increase the domestic production rate.

Now they have raised this indicator to 70 percent, and, moreover, they have passed this most important experiment!

Most of the people are alternately on duty, and at this final moment, they all gather together, but there are also some people who have been staying here, for example, Zhuang Zicheng, who is in charge of technology, has been staying here, he has set up a military bed next to him, guarding the test bench, and once there is a situation, he can react at any time.

Now, Zhuang Zicheng's eyes are red, but his face is full of joy: "Great, we have completed 70% of the localization work, and now, the boss will no longer complain that we can only use foreign parts to assemble!" ”

At present, there are many military vehicles waiting to be assembled with it, such as tractors from Hanyang Factory, heavy trucks from Iron Horse Factory, various armored vehicles, and infantry fighting vehicles.

This excellent power, can not always introduce parts production, improve its localization rate, the significance is quite significant, after the improvement, but also have to go through a harsh test!

Now, it has been working steadily for a thousand hours in the range of maximum speed! Its performance is still quite reliable, which shows that the efforts of Beihua Diesel Engine Factory are worth it!

"Director, there's a guest outside." Just as everyone was cheering, a worker ran in and said to Ye Qiming and Zhuang Zicheng.

"Guests? Where did it come from? ”

"Prairie City, a machine factory."

A machine factory?

In the whole system, a machine factory is famous, and people make dollars! Hearing this, Ye Qiming and Zhuang Zicheng were overjoyed: "Where are they?" ”

"Everyone has worked hard, Director Ye, Director Zhuang, hello." At this moment, there was already a voice outside, and Qin Zhenhua walked in with a few people.

In addition to the strict management of the first-line large factories, the management of this kind of third-line small factories is not good, in the past, perhaps the security of the third-line factories is more serious, but now...

Who wants to stay in a poor ravine! Capable people are running away to the big city, not to mention the technicians, a security officer, and they can't wait to be transferred out quickly.

Ye Qiming and Zhuang Zicheng looked at each other, especially when they saw that there was actually a woman in the team who came, and it was still a foreign woman, they were even more surprised.

"You are, Assistant Qin of the First Machine Factory? Who is this? Ye Qiming can only analyze according to the other party's age, temperament, and current situation, the other party should be the assistant Qin, and what about this woman?

"Mia, I used to work for MTU Diesel Engine Company, and now as the plenipotentiary person in charge of Mercedes-Benz heavy trucks in our eastern country, speaking of which, you are still peers. Let's take a look. Qin Zhenhua said with a smile.
