Dreaming back to 1949, the great powers were there to deceive us

At Xinzhong Machinery Factory, Hu Zhenhua looked at the three machines in front of him and they were indeed different.

The engine was produced by Xinzhong Machinery Factory, the gearbox was taken from a second-hand car, and the chassis was hand-welded.

Objectively speaking, these three machines look nothing like each other, with crude workmanship and weird appearance. One word to describe them is: ugly!

But it can be done in less than ten hours, what more can you ask for!

Hu Zhenhua stroked the carriage. The corners were not rounded, there were burrs on the welds, and it was not painted.

These are details that can be dealt with later.

Hu Zhenhua lay on the ground and observed the area.

The shock absorbers are made by stacking steel plates, and this method is still used by trucks even in the 21st century.

Hu Zhenhua smiled.

He thought of independent suspension.

Although I don’t know the specific technology, I know the general principle!

Another way to make money. Whoever uses this system in the future must pay me patent fees!

The chassis structure of the Sibu Xiang is similar to that of later small trucks.

After Hu Zhenhua stood up, he just turned around and had a rough idea in his mind.

He grabbed the hand crank, inserted the pin, and prepared to crank the shaft to start the engine.

Suddenly, Lao Hu remembered something, walked to the cab, pulled the handbrake, put the gear lever in neutral and stepped on the clutch pedal.

After confirming that everything was correct, Hu Zhenhua jumped down and stood on the left side of the vehicle, about half a step away from the bumper, with his feet shoulder-width apart to maintain his balance.

He held the crank handle with his right hand as the main hand, and pressed the pressure reducing valve with his left hand as the auxiliary hand. The purpose was to reduce the pressure in the cylinder when shaking, making shaking easier.

Hu Zhenhua took a deep breath, first pressed the crank handle downwards, and then pulled it up with force.

He shook it clockwise, faster and faster. When the flywheel gained enough inertia, Hu Zhenhua released the decompression handle, the valve closed, and the diesel engine quickly pressed through during the compression stroke. The engine started and made a "da da da" sound.

Dull and powerful.

Just now, Zou Du, the manager of Xinzhong Machinery Factory, was very worried, fearing that Hu Zhenhua might be injured due to improper operation and failure to release the crank handle in time.

Now it seems that his worries were unnecessary.

Hu Zhenhua seemed very familiar with this type of vehicle.

No, this car is the one based on the drawings provided by Hu Zhenhua, how could he not be familiar with it.

The smooth start of the vehicle made the people around him breathe a sigh of relief.

These three prototype cars are related to the survival of hundreds of factories.

Hu Zhenhua leaped into the cab. The deep rumble of the car instantly made his blood boil. He slowly stepped on the accelerator, and the Sibuxiang began to move forward steadily.

Lao Hu stepped on the accelerator. He could feel the power of the car being transmitted continuously, as if it had endless energy.

He drove onto a rugged road. The shock absorption of the Sibu Xiang was only average. Once the road surface was bumpy or bumpy, the car body would shake violently up and down.

Hu Zhenhua saw a steep slope and tried to speed up to rush over it. The car climbed up effortlessly and he was amazed by the powerful torque.

He was a little cautious at first, but soon discovered that the Sibu Xiang's maneuverability far exceeded his expectations. The steering wheel responded precisely to his movements, and the car turned nimbly with almost no roll.

As the test drive progressed, Hu Zhenhua became increasingly immersed in this unique experience. As he sped across the wilderness, feeling the wind whistling in his ears, he gained a new appreciation and admiration for this unique vehicle's capabilities. When he finally stopped the car, over an hour had passed, and a smile of excitement and satisfaction filled his face, as if he had just experienced a thrilling adventure.

The no-load test drive made Hu Zhenhua very satisfied. Next, it was time for the load test!

The three vehicles are different and are equipped with different engines, namely 20 horsepower, 45 horsepower and 110 horsepower, with loads of 2 tons, 4 tons and 11 tons respectively.

The one Hu Zhenhua just test drove was the 110-horsepower one.

"Load up the sand and gravel!"

The carriage is 3.5 meters long, 2 meters wide, 0.8 meters high, and has a volume of 5.6 cubic meters.

According to Hu Zhenhua's requirements, the carriage must be able to run normally when fully loaded with gravel!

The density of gravel is about 2.5 tons per cubic meter. If fully loaded, the weight reaches 14 tons!

Zou Du's face looked a little unhappy.

This is an overload of 3 tons!

Although he claimed that the rated load could reach 11 tons, that was only a theoretical figure after all, and it might not be achievable in reality!

Zou Du immediately reminded Hu Zhenhua tactfully,

"Mr. Hu, it's overloaded!"

"We have to consider the actual usage of customers. They just fill the carriages without weighing them one by one to see if there is any overload!"

Zou wanted to slap himself in the face. If he had known this would happen, he should have made the carriage smaller. But now that the matter is done, what else can he do?

He rolled his eyes and shouted,

"Mr. Hu, you are worth a fortune, how can you take the risk yourself? Let someone else do the test!"

Hu Zhenhua was in high spirits and didn't understand Zou Du's implication at all, so he refused outright.

"Manager Zou, thank you for your kindness. I want to experience it myself!"

Seeing that his plan was failing, Zou Du thought for a moment and came up with another plan. He smiled and said,

"We've been running for over an hour. Do you have enough gas? Lao Wang, go and fill it up!"

The diesel used in the fuel tank now is domestically produced.

The reason is, it’s cheap.

Xinzhong Machinery Factory was so poor that it could barely make ends meet, so naturally they tried to save wherever possible.

Zou Du wanted to slap himself in the face. Why save your energy at this time? Fortunately, Xinzhong still has two barrels of imported diesel.

Originally, according to Zou Du's idea, the diesel in the Sibu Xiang was to be extracted and replaced with imported diesel.

But doing so was too obvious and would arouse Hu Zhenhua's suspicion. Helplessly, he could only pour imported oil into the fuel tank and mix it with domestic oil.

This test was conducted by Hu Zhenhua himself. This was the only thing Zou could do.

After filling the container with pebbles, Zou Du's heart was in suspense.

Hu Zhenhua didn't think too much about it. He stepped on the accelerator lightly and the engine made a dull sound. Because the vehicle was too heavy, the amount of fuel Lao Hu gave was not enough to pull the Sibu Xiang, so he stepped on the accelerator.

The roar of the engine spread all over the place.

A few puffs of black smoke came out of the chimney, as black as ink.

After the vehicle shook slightly a few times, the wheels finally moved, faster and faster.

In the no-load test just now, Hu Zhenhua estimated that the maximum speed could reach 50 kilometers per hour. Now, Hu Zhenhua kept stepping on the accelerator, and the Sibu Xiang ran faster and faster.

Soon, the critical speed was reached. Lao Hu estimated that the speed was about 40 kilometers per hour.

This speed is completely incomparable to that of later generations.

Considering the poor road conditions in China, Hu Zhenhua decided to test the obstacle crossing ability.

He slowed down and the first place he chose was a dirt pit.

When fully loaded, if the wheels pass through the tunnel, it will cause a huge impact on the chassis, which is a huge test of the vehicle's sturdiness.

Zou Du saw Hu Zhenhua's intention and his heart was in his throat.

To secure the order, Xinzhong Machinery Factory used the best workmanship and materials, but due to the tight deadlines, some omissions were inevitable.

"It's definitely okay, it's definitely okay!"

Amid Zou Du's prayers, the Sibu Xiang's revolver arrived at the tunnel, and under the action of gravity, the center of gravity of the revolver settled.

The balance of the Sibu Xiang was broken and it fell violently.

We all know that the greater the pressure, the greater the rebound force. In less than a second, the vehicle bounces high up and drives out of the pothole.

"Wow!"

Hu Zhenhua screamed with excitement. Although he was prepared, his butt still hurt from being hit.

The employees of Xinzhong Machinery Factory burst into thunderous cheers.

They jumped, they danced, they roared, like crazy!

The technicians and workers are not afraid of hard work or fatigue, but they are afraid of not having orders.

One test was not enough, so Hu Zhenhua turned the car around and prepared to continue to ravage the bumpy road.

Others would slow down when passing a pothole, but Lao Hu maintained a high speed of 40 kilometers.

It was the left wheel just now, this time it’s the right wheel!

Amid Zou Du's fear and countless workers holding their breath, the Sibu Xiang passed through the bumpy ground at high speed again and again.

Zou Du's notes were densely packed with records of the number of times he had passed the pit. He had become numb, and from the initial nervousness, he had become calm and composed.

The reason is that he not only adapted to this kind of test, but more importantly, Zou Du had enough confidence in his product.

After testing the pit, Hu Zhenhua started testing the hill climbing.

The first test was a slope of about 5 degrees. Lao Hu controlled the speed at 10 kilometers per hour and drove slowly up.

As soon as the car touched the slope, the sound of the four-cylinder engine immediately became dull, as if someone was pulling the car uphill and breathing heavily.

This four-cylinder engine is the highest level engine that Xinzhong Machinery Factory can manufacture.

When the speed of the Sibu Xiang slows down, the tires have stronger grip.

The dull and powerful sound of the engine lasted for two minutes. After passing the slope, the light sound rang out again, like a child cheering.

Next, there is a 10-degree slope.

After that, 15 degrees, 20 degrees...

By the time it reached the 45-degree slope, the Sibu Xiang had become as slow as a snail. If the road had been slightly slippery, it would have definitely not been able to go up.

This is the limit of climbing.

Overall, Hu Zhenhua is still satisfied.

Because he didn't have high expectations for vehicles of this era, if it were in the future, Hu Zhenhua wouldn't even give this kind of driving experience a second glance.

The vehicle stopped steadily in front of Zou Du.

Hu Zhenhua stood up and jumped out of the car, only then he realized that his butt was sore.

Zou Du supported him and asked anxiously,

"Mr. Hu, are you satisfied with the vehicle?"

Hu Zhenhua looked back and smiled.

"Tear the vehicle apart and check for any damage, especially the shock-absorbing steel plate!"

Zou Du's brows twitched, thinking that Hu Zhenhua was not easy to fool at all. At the same time, he was very glad that he did not cut corners.

Last night, the deputy factory director suggested using the next-level steel because this is a prototype car and once it passes the review, subsequent production will be carried out according to this standard.

By using lower-grade steel, the cost of the entire vehicle can be reduced by at least 20 oceans.

However, Engineer Qi Zun strongly objected, because he could tell at a glance that the Sibu Xiang might be a mining vehicle with high load-bearing capacity.

Once an accident occurs, the car may be destroyed and people may die.

The two argued endlessly, and in the end, Zou Du made the final decision.

Xinzhong Machinery Factory is almost at the end of its rope and dares not take any risks.

Fortunately, the Sibuxiang test performed excellently.

After Zou Du arranged for people to dismantle the vehicle, he helped Lao Hu to the side and served him tea and snacks that had been prepared in advance.

Hu Zhenhua thought about the slope he had just climbed. The Sibu Xiang weighed only 3 tons, and with the load it was only 17 tons. There was no reason why it couldn't even climb a 45-degree slope.

There seems to be a single-cylinder engine in later generations, which is used on hand tractors. Rural areas usually use it to pump water, pull goods, and plow land. It is very powerful. When Hu Zhenhua raised this question, Zou Du immediately gave an answer.

"Mr. Hu, our factory also produces the single-cylinder engine you're talking about. This diesel engine has a low speed and, through a special design, can generate very high torque. This is advantageous on complex roads, when climbing slopes, and when carrying heavy loads. However, this comes at the expense of vehicle speed. Mr. Hu, are all the vehicles you see moving slowly?"

Hu Zhenhua suddenly realized,

"I see!"

Those tractors in the countryside usually move slowly, not much faster than walking.

Zou Du was quite emotional and said,

"If you want high speed and high horsepower, multi-cylinder engines are the way to go. For example, the gasoline engine used in the US Patton main battle tank is the AV-1790 produced by a mainland company. It has 12 cylinders and a very powerful engine, up to 810 horsepower. Another example is the M60 main battle tank, which uses a 12-cylinder air-cooled diesel engine with a maximum power of 750 horsepower. In the field of engines, we still have a long way to go!"

Hu Zhenhua thought for a moment and asked,

"If I get you a sample, can you imitate it?"

Zou Du opened his mouth, not knowing how to answer.

Hu Zhenhua understood what he meant: Not sure!

"I can give it a try, but it may not work."

Is imitation so difficult?

Hu Zhenhua nodded. Since he had encountered the problem, he would definitely help if he could.

Go back and place some more orders with WWA to get the engines.

Hu Zhenhua pinched his chin and thought for a while, if the high-end one doesn't work, then let's try the low-end one.

Farmers of this era were still limited to carrying water to irrigate the fields. After working hard all day, their shoulders were worn out, but they still couldn't carry five cubic meters of water.

Lao Hu took out his notebook again and started drawing. After more than ten minutes, a simple tractor took shape.

"Mr. Zou, can you produce this kind of simple tractor?"

Zou Du took a look and smiled.

"No problem. If we start production of this water-cooled single-cylinder diesel engine, we can produce at least 800 units a month!"

He leaned over the drawing and took a look, then asked,

"What is the steel plate extending in front used for?"

"This is reserved for the water pump. When you produce it, I hope the front few steel plates will be made removable!"

Zou Du immediately gave a rainbow fart,

"Mr. Hu is indeed very thoughtful. He installed a water pump, which makes the tractor more versatile. This tractor is sure to be a big hit!"

Hu Zhenhua was very pleased with this and laughed heartily, pointing to the rear of the tractor and saying,

"There's a latch in this place, leaving space for a tow truck! Oh, and there's also a trailer hook at the back of the Sibu Xiang!"

If light and bulky goods are being transported, a trailer can be added to increase the transport volume. After all, the fuel consumption of the Sibu Xiang is not low, and every bit of transport capacity cannot be wasted.

"no problem!"

The two chatted enthusiastically and got along more and more!
