Since it is something that everyone wants, then I will no longer be inscribed. Everyone is a man, so you have to do things quickly.
Qin Zhenhua smiled, looked at everyone, and then walked to the test drive table.
Looking at the red cloth, Qin Zhenhua covered his excitement and walked forward, pulled off the cloth, and the V-shaped 12-cylinder engine was exposed in front of him.
The upper side of the engine is tilted to the outside, which is the cylinder head. There is a thick exhaust pipe on each side to connect them together. At one end of the cylinder, there is a turbocharger like a snail-shaped one, and the entire engine is
It was also painted red, which looked quite festive, and the body part below it.
Although it looks no different from an ordinary engine, and it looks almost the same as the one thousand horsepower engine, in order to output more power, this engine is also soaked in everyone's sweat.
of.
For example, in order to achieve greater pressure, there must be a supercharger with stronger performance. The snail-shaped climbing high-pressure than the turbocharger, which contains the sweat of designers, and refers to the foreign colleagues.
Based on the MTU engine, there have been greater progress, improved processes and new materials.
Only the turbocharger is not good, and there is also a high-pressure fuel injection pump that injects more fuel into it. At the same time, to withstand more powerful combustion, a high-load piston group is required and a more stress-bearing one is required.
Large new bearing tiles, etc.
Every component took several years to develop.
Not to mention anything else, just take the body of this engine as an example. The entire body and the cylinder head on the top are made using the latest pouring process. The technicians and workshop workers of the first machine factory are almost all for
This has dedicated my youth and sweat.
At this time, Qin Zhenhua had a strong feeling in his heart, looking at the engine with red cloth that had been unveiled. A few years ago, he was still doing research together, but in recent years, he has gone to the outside world.
As we run more and more times, we have less energy in research and development. In the second half of the stage, almost all the people from the engine branch were made by themselves.
This is also a necessary path for development. After all, if a machine factory wants to develop, it needs to constantly sell the equipment. For Qin Zhenhua, this is already a responsibility he cannot refuse, and he must solve it.
The issue of selling equipment, and with the establishment of the Northern Company, Qin Zhenhua shouldered more responsibilities, not only himself, but also the entire military system, which he needed to promote.
The first machine factory has also developed and has cultivated a scientific research team and embarked on the path of healthy development.
"By the way, where is the coal provincial diesel engine factory?" Qin Zhenhua asked.
There were many grudges at the beginning. Later, I worked closely with the coal-provincial diesel engine factory to jointly develop tank diesel engines. Their joining did accelerate the progress of research and development. As of now, the progress of this tank engine is so
It was quick and also helped by the coal province diesel engine factory.
"The Black Panther diesel engine they manufacture will probably be assembled next month and will also participate in the test." Wu Ruihua said: "After all, if you want this diesel engine to mature, you need about a dozen diesel engines, and there are on the test drive table.
There are also practical tests for loading and real-time vehicles. We have to run for hundreds of thousands of hours before we can ensure its reliability.”
The coal-provincial diesel engine factory is also ready to test the engine, but it is just a little later.
Qin Zhenhua nodded and began to look at the activated switch.
There are many differences in the starting methods of tank engines. In the past, compressed air was often used to start, but the way of starting compressed air was not as convenient as electric start. Therefore, most of the new generation of tanks use electric start.
way.
There is a special knob in front of the test bench, with two gears on it, one is preheating and the other is starting. After all, for tank engines in cold areas, there is a special preheating plug inside. Give it first
The cylinder is heated inside and then started again.
Now, although it is cold outside, it is as warm as spring inside, so there is no need for a preheating plug. Qin Zhenhua walked over and turned the knob under everyone's eyes, turned the knob and turned the preheating directly.
That gear is transferred to the bottom.
With a squeak, the starting motor was rotating, and the gear was thrown out, matching the engine's flywheel ring. Then, in the thick and powerful sound, the motor turned sizzlingly, driving the engine to make a roar.
The two thick exhaust pipes also began to emit black smoke constantly.
The engine starts by using external forces to make the engine run by itself, and then burn it and stabilize it, and you can drive your own operation. This is the normal starting process of an engine.
At this time, the engine was repeating this process. The starting motor drove the crankshaft to rotate. Diesel was sprayed in from 12 cylinders and burned through the work. Then, the engine began to shake, the noise began to increase, and the black smoke still
It is emerging outwards.
Is it necessary to fail to start?
At this moment, everyone began to murmur in their hearts.
This first 1,200-horsepower engine may have problems when starting, and everyone is prepared. However, if it really happens, it will still make people feel embarrassed.
.
Therefore, during this first test run, I didn’t look for others, they were all my own people. Zhu Lao worked in a machine factory back then, and he was also considered an old acquaintance.
Just when everyone was confused, finally, the sound of the engine became lighter, the black smoke faded, and the sound of the starting motor became even more relaxed. Then, Qin Zhenhua released the knob.
Generally speaking, an ordinary starter motor must stop after working for more than ten seconds, otherwise it will be easy to burn. But just started for the first time and ran for half a minute. The starter motor also endured a severe test. Qin Zhenhua had just
I am also a little worried. If the startup fails to succeed, it will bring some pressure to everyone.
Fortunately, this engine did not disappoint everyone, and with Qin Zhenhua's insistence, it finally started!
There were bursts of cheers and applause from the scene. Qin Zhenhua announced loudly: "The 1,200-horsepower Black Panther diesel engine developed and produced by our first machine factory has been successfully ignited! Our first machine factory has put a big satellite on it.
