Qin Zhenhua has always emphasized that the potential of the 12150 diesel engine has been fully tapped, and the biggest problem is the heat dissipation problem caused by the small cylinder core distance, which is even unsolvable.
Originally, everyone didn't think so and didn't take it seriously. However, as the 1,000-horsepower diesel engine was put on the bench, Zhang Baolin had realized that this problem may be the biggest problem that restricts its power improvement. He wants to change it.
, can only increase the distance between the cylinder center?
If it is improved, isn’t that the diesel engine project currently being developed by the First Machinery Factory?
The team led by Zhang Baolin is currently working hard to solve the heat dissipation problem. After reaching 1,000 horsepower, no matter how the radiator is added, they will find that the water temperature of the engine will rise quickly and then it will not be lowered, accompanied by other explosions.
Not to mention problems like cylinder heads.
This time, Zhang Baolin was also very excited when he heard that the T-72 tank was brought back. He hoped to find some experience from this diesel engine to improve his own diesel engine. However, who would have thought that Qin Zhenhua poured him this way.
A basin of cold water.
800 horsepower is the limit. Look at the Soviets. The 780 horsepower diesel engine is inevitable in the desert. It can only reduce the power and operate. It is useless to improve heat dissipation!
If this is the case, then there will be problems with their route. If there is a problem with the route, no matter how you study it, it will be impossible to make progress.
Zhang Baolin had such an ominous premonition in his heart, but now, his face still cannot be expressed. He looked at Qin Zhenhua, and Zhang Baolin's face changed into confidence. You said no, pour cold water on us, just so that we could wake us up.
, We will continue to study carefully until these problems are solved.
"Only competition can there be development. There is still a satisfying motivation in our industry." Old Zhang looked at the confrontation between the two with a smile on his face: "It's embarrassing to wait for a pie to fall from the sky."
Mr. Zhang's feelings are based on Qin Zhenhua's words. It seems that Qin Zhenhua's influence is getting bigger and bigger. His words today also represent those who have already gained benefits. I guess they have to go back.
Spit out the benefits.
After all, who dares not listen to Mr. Zhang?
"The Soviets' engine has another feature, it is a multi-fuel hybrid engine." Wang Tianming continued: "Can we also refer to the design of this engine in our domestic engine?"
Since World War II, diesel engines have shown great performance. They are durable and have high fuel savings. With the same fuel tank, the diesel engine has a range of several times that of gasoline engines. Therefore, after World War II, almost all tank engines were diesel engines.
.
Tanks are monsters that drink oil. The fuel supply of tanks is a big problem. On the battlefield, if the tank urgently needs fuel, but there are only different types of fuel on the spot, what should I do at this time?
At this time, the multi-fuel mixing engine has an advantage.
Now, the B-46 diesel engine used by the T-72 tank in front of us is a product of this idea. It can burn diesel, kerosene, gasoline with an octane number of 68 to 78, and a mixture of the above fuel.
In the driver's position, there is a special runner marked with three letters: Д, К and Б. Different positions use different fuels, and even when mixed fuel is needed.
As the overall tank designer, I am very interested in this function, but for engine designers, this means that I have to put in more effort. Even the diesel engine can't handle it. Now I want to make it a
Is it a multi-fuel mixing engine?
Qin Zhenhua smiled: "It's OK, the technology is not complicated, but, as far as I know, whether it's the Soviets or the people of a certain desert country, they have never had any other fuel added to the T-72 they equipped.
”
"Why?"
"Because tank soldiers are afraid of trouble." Qin Zhenhua said: "If they pour other fuels and the training is over, they have to clean the oil circuit again and replace various components such as filters. On the surface, it seems to be adapting to the needs of the battlefield.
, but in actual operation, it is really too complicated. If they have gasoline on hand, they would rather wait for the diesel supply truck than add on site.”
"As for us, there is no practical need." Qin Zhenhua continued: "Our army is almost all diesel engines. The main fuel provided by the troops is also diesel, so we have to worry about gasoline only.
Is the problem? It should be a 212 Jeep. Is it better to consider how to add diesel?"
Everyone suddenly realized.
Many things are beautiful to say, but when designing, there are many factors to consider, but when actually using them, they are not the case.
It's like a folding bicycle, which is for the sake of being small and easy to carry. However, after it is really used, how many people will fold it?
"The deck in front is also very interesting." After discussing the engine behind, everyone looked at the deck in front. Looking at the unique V-shaped structure on it, it was very strange.
For a tank, the deck in front of the car body is also the thickest place in addition to the cannon shield. Now, the deck in front of this tank has a V-shaped structure, in this
In the V-shaped structure, there are also horizontal reinforcement ribs.
I have hardly seen it on tanks before.
"This is also a useless design," said Qin Zhenhua: "The scientific name of this thing is called a waveproof board. It is to prevent water from pouring into the cab."
Tanks, how to prevent water from pouring in? Tanks have turned into ships?
That's true. In the tank test, one aspect is wading in the water. When a tank encounters a stream or something, it can drive directly over. As long as the water does not flood the turret, there is no problem.
Of course, when flooding, there is also a way. The tank will have a special snorkel, and it will even be more than ten meters high. The tank is fumbled forward in the water below more than ten meters. This snorkel can ensure the breathing of members of the vehicle body and
The use of the engine, even on the top of the snorkel, can crawl and command there.
Of course, this function is rejected by any tank soldier, and it is a super VIP among the useless.
It’s fine if you pass a stream more than one meter deep. It’s better to wait for the engineer to build a bridge.
If it is rainy, you can see that the front of the car will push the water to both sides. Therefore, the water surface on the engine cover is actually lower than the normal water surface.
This V-shaped waveproof board has the same design concept. Its V-shaped design can effectively prevent the waves on the head of the car, and direct the waves to both sides so as not to splash into the cockpit in the middle of the head of the car. Of course, at this time, drive
The officer drives with his head exposed, and it doesn't matter if he closes the hatch door above his head.
At the same time, inside this V-shaped, the horizontal reinforcement ribs can increase protection. If the eyeless armor-piercing bomb hits the reinforcement ribs, the holes that need to be drilled through will become deeper.
