Outside the engine, a layer of silver anti-rust paint was sprayed, sparkling under the light. At this time, countless people were here, waiting for the moment to witness the greatness.
Their faces were full of excitement. When Qin Zhenhua walked in, they didn't look back to see who was coming in, but were just waiting for the bench test drive there.
"Director Zhuang, we have made all the preparations. Can we start now? Hey, this is Director Qin?" At this time, the person in charge of the test reported to Zhuang Zicheng and found that Zhuang Zicheng was following.
It was Qin Zhenhua, and he was immediately surprised.
"That's right, it's me. I'll join in the fun. Since it's ready, let's start." Qin Zhenhua said: "If this test drive can be successful, I will take everyone to Jianli Hotel to celebrate tonight!"
Jianli Group is already a well-known domestic enterprise, with branches in various provincial capitals. Qin Zhenhua said that he invited them to dinner, and of course he went to a nearby place to eat. When he heard Qin Zhenhua say this, someone shouted: "Qin."
Long live the factory manager!”
"It's all the time, and I still shout such slogans." Qin Zhenhua shook his head: "It's old, let's start quickly."
The crowd was noisy for a while, happy for Qin Zhenhua's arrival. After returning to peace, the test finally began.
"Now, inject fuel and remove air from the pipeline!" shouted the person in charge of the test.
The pneumatic power of a diesel engine is more complicated than a gasoline engine. It requires the air in the pipeline, otherwise it will not be successfully started. After receiving the order, the relevant technicians quickly took a shot manually. Looking at the engine, Qin Zhenhua sighed: "Better than us."
The 150HB diesel engine is much smaller. If this power is fine, it can be expanded to 12 cylinders."
The diameter of the piston is smaller, and the overall engine is reduced in size. The current eight-cylinder engine is less than one meter two in length. Even if it is expanded to twelve cylinders, the length is about one meter five, which is more than a 150HB diesel engine.
The length is much shorter. If this power system is stuffed into the 99 tank, it can continue to reduce the size of the engine compartment.
His words made the people present even more excited. If they could match the third generation of main battle tanks in the future, it would be better.
"The exhaust ends!" someone shouted.
"Okay, ready to start." The person in charge said, turning his head to look at Zhuang Zicheng and Qin Zhenhua: "Who will turn the start knob?"
"I'll do it." Qin Zhenhua volunteered to come to the front of the operating table, holding the start knob with his thumb and index finger, and then twisting it.
If it is an ordinary car, it is all used to start the key, but military vehicles do not have keys. On the battlefield, cars need to be able to start at any time. Therefore, it is generally a way to start the knob, even if there is a key, the key will be
It needs to be inserted in the car and cannot be taken off.
At this time, as Qin Zhenhua twisted, the starting motor made a buzzing sound. The entire bare-exposed engine immediately saw the belt rotate, but the cooling fan did not rotate, because the cooling fan and the engine
The belts are connected by a special silicone oil clutch. They will only operate when the engine is running normally and the water temperature begins to continue to rise, and they do not rotate normally.
The engine's oil pump made a rhythmic clattering sound, and the fuel injection sound inside the cylinder rang, and then the engine's exhaust pipe began to exhaust the air outward, passing through special pipes, directly
Line up outside.
At this time, various data were also displayed on the operating table.
Unlike the test run in the past, the old technicians needed to see, hear, and touch them with their hands. The current engine has achieved electronic monitoring. There are a large number of sensors on the engine parts, and these sensors are providing a large amount of data.
Then input it to the operating table, and on the display screen, it directly synthesizes curves.
"High technology is good." Qin Zhenhua looked at the screen and said sighing. While he was talking, the engine had already started to make rhythmic sounds, so his hand also released the start knob.
The engine has already been spinning itself, and the ignition has achieved a complete success!
"Eight hundred revolutions per minute, idle running, all kinds of data are normal." At this time, the technicians beside him looked at the various data on the screen and said to everyone.
The engine runs smoothly, the data of each sensor is normal, and the water temperature begins to rise slowly, but the pressure of the turbocharger is zero. At this speed, the turbo will not work. Zhuang Zicheng looked at it and said:
Now, increase the speed to 1,200 rpm.”
"I understand, the speed has increased to 1,200 revolutions." The tester said, and began to push the operating lever on the side. Anyway, this kind of diesel engine is already electronically controlled, not an ordinary pull-up throttle. This operating lever controls a single
Just a electric gate sensor. Now, as he pushed the operating lever, the speed of the diesel engine began to slowly rise, and the engine sounded louder. At the same time, the turbine was blown up and began to whistle, the turbine pressure value
It also began to increase rapidly.
"Yes, this has reached 500 horsepower." Qin Zhenhua looked at the numbers displayed on the horsepower machine and nodded with satisfaction. It was only 1,200 turns. If it reached 2,400 turns, it would be output according to the same technical level
If that's one thousand horsepower!
Of course, this is not a proportional relationship. After the speed increases, the fuel injection volume can be increased. However, whether the engine can output the corresponding power depends on whether the turbocharger is powerful and whether it can provide enough air.
If not enough, then the oxygen will be insufficient and the combustion will not continue to accelerate.
"Elevate to 1,500 revolutions." Zhuang Zicheng continued.
In fact, there is no problem with this level of test. After all, the original engine can already achieve this power. The key is how to output higher power. After increasing the speed, the situation will also change.
If a certain component cannot withstand it, the engine will malfunction and may even explode.
Back then, when the turbocharged tank engine was improved for the first time in China, we encountered problems one after another, which gave designers a headache. Now, can their engines withstand it?
The engine speed continues to increase, the engine water temperature is also increasing, and the fan in front begins to rotate.
