This time, Cheng Zhijie was not the only one who came with Li Yuanji, and the last time it was a temporary decision. ◢ With * dream * small ◢.1a

But this time, many ministers put down their work and followed them to the test site, wanting to see with their own eyes what the truck that Li Yuanji had high hopes for.

Of course, with the magic of the train as a base, they may be surprised when they see the truck, but the shock or anything still doesn't show up.

Li Yuanji affirmed Jiang Tian's thinking, which is also the practice of later generations, and the principle is not difficult, but Li Yuanji has no intention of reminding him.

I'm going to cool them down, let them figure it out on their own, and that's a way.

However, what Li Yuanji didn't expect was that the ministers were excited because of this.

Several people scrambled to get up and experience the truck, but of course, they went with different purposes.

Trucks are not only useful for the army, for example, the Ministry of Industry, in recent years, the construction task of the Ministry of Industry has been relatively heavy, so the Ministry of Industry Shangshu fell in love with the big guy at first sight.

It doesn't matter if the temperature is high, what kind of ammunition is the death of the clouds, Lao Tzu takes him to pull the soil and cement and the steel bar, are these things like the master who is afraid of the heat?

Once you have these big guys, the progress of the whole project will be much faster.

And, in terms of investment, there will also be a lot of savings.

At present, in order to avoid all kinds of losses caused by long-distance transportation, the Ministry of Industry can only take a distance of 500 miles to build a supporting material production workshop, although it can continue to be used in various places after the construction.

But the problem is that there are these workshops in various places, and there are not many of them that can really be put into use.

One is that there are some of the same workshops in each place, even if they are not large enough. Second, in order to avoid excessive waste of resources, the Ministry of Industry has done so.

So now it's a supporting workshop that is desperately producing in one place, producing enough to support the needs of all the materials used within this distance, and even more than a part.

After that, the entire workshop was dismantled and moved to the next place to continue assembling and producing.

But with a truck, there is no need to be so troublesome, and it is not easy to move equipment or anything at once, and it takes a lot of time, energy and manpower on the way.

According to previous experience, every time a house is moved, the Ministry of Industry needs to spend nearly 100,000 yuan for it.

And the frequent disassembly and assembly also has a great impact on the equipment itself, and even the Ministry of Industry has come up with the results, the current workshop, at most once again, next time, whether it can operate normally is a problem.

If you can, these trucks can definitely avoid the relocation of the workshop back and forth, after the construction of a section of the railway, the relocation cost alone has reached hundreds of thousands, and with the truck, it is completely possible to transport materials there in advance to prepare for use.

At the suggestion of many ministers, Li Yuanji also personally boarded a truck to experience it.

Li Yuanji's identity is there, so he is on the stage with the largest physique.

The layout of the cockpit is simple, so simple that there are not even seats...

Jiang Tian completely referred to the design of the rudder on the ship, and also installed a rudder on the truck, and the driver stood in the center, with a very good line of sight, and there were very few blind spots.

On the left-hand side is the valve that controls the steam, which is certainly not as advanced as later generations.

Clutch, don't think about the throttle, no one knows what that thing is.

It is not difficult to drive this truck, but it is very simple, a total of two people are required to operate, one is the driver, who is responsible for controlling the rudder and valves, and the other is the co-pilot, which is to put it bluntly, it burns coal.

However, unlike a train, this coal is dropped from above, and the speed is reduced by the internal preset slope to prevent the fire from being extinguished.

Moreover, the amount and frequency of coal burning are not high, and the design of the coal bunker behind is also somewhat eye-catching.

The truck is not a train, and it is impossible to carry a coal water truck, so on the truck, it is set up as a special coal bunker, and a separate water bunker is set up in front.

Coal bunker coal needs to be added from the top, after filling up a top cover with an inverted buckle, after fixing, it can prevent rainwater from entering, and the bottom is a funnel shape, about 30 centimeters away from the ground, the mouth is very large, the diameter is about 30 centimeters, after opening the mouth, the coal will fall down, and then take the specially built coal bucket to produce some and pour it in.

Because the steam engine is small, the demand for coal is not as large as that of the train, and similarly, because the steam engine is small, it heats up very quickly.

In less than a moment of tea after ignition, the truck can move slowly, of course, very slowly.

Although driving such a truck is very simple and basically does not require much operation, Li Yuanji looks very difficult.

The driver, in particular, is definitely more tired than the one who burns the boiler, how tired? Just look at the image of the driver now.

The truck had just been on the road for a short time, and after a few turns, the driver's forehead was covered with sweat.

Although the speed of the car is getting faster and faster as the temperature in the boiler gets higher and higher, for the driver, turning is the biggest pain.

First of all, before turning, he has to close the intake valve and open the air release valve at the same time to avoid the danger of excessive pressure in the boiler.

Then there is the rotation of the rudder wheel, because the rudder wheel is directly used to drive the first two wheels with gears, and when the wheels hit the ground, it is particularly heavy, even if it is driving, this strength will be reduced, but it is still not easy to control it for a long time.

There are no hydraulic auxiliary devices, and I don't even know if there is lubricating oil added to the gears below to assist, anyway, this car has been driving for a long time, and it can definitely tire people to death.

Moreover, this rudder is a reference to the design of the ship, which has one more turn than going straight up and down, and needs to go in a figure 7 shape, which invisibly increases some difficulty.

"I'm going to give it a try!" Li Yuanji wanted to experience it and see how laborious it was to manipulate this.

The driver hesitated, and even Ma Wu beside Li Yuanji hesitated, but after all, he still didn't stop it, but Ma Wu stood directly next to the valve, and at the same time stopped the co-pilot from continuing to add coal.

Li Yuanji was born in martial arts, although he has lost a lot of martial arts over the years, he has always had the training, so his hand strength is actually not small.

Steering the rudder wheel around a few times, it seems to be more labor-saving than imagined, but for an ordinary person, it is definitely not labor-saving, according to the current situation, even if Li Yuanji operates it himself, not to mention three consecutive hours, it is good to be able to hold on for two hours.

"You try!" Just experienced it, Li Yuanji lost interest, and then asked Ma Wu to experience it too.

Well, Ma Wu's operation is a lot more spiritual, and it also saves a lot of effort, and it seems that this consumption does not have much impact on him.

Let's not talk about the speed or anything, everyone is a novice, and they don't dare to open it too fast, but it can be clearly felt that this is not the fastest speed, and even the valve was only opened a little before.

Even if it can have this speed when it is fully loaded, it is much faster than a horse-drawn carriage, and this thing burns coal and drinks water, and the need for food is equal to zero, which is the biggest benefit.

After some operation, Ma Wu gave up the driver's seat, he came to protect Li Yuanji, not to try it, just experience it.

Of course, the experience cannot be a simple experience, and it is necessary to give some advice.

"It's a bit heavy, and it's standing all the time, maybe there's no problem in a short period of time, but if the army uses it, sometimes it's possible to run for a few days in a row, so standing all the time, plus the operation strength of the rudder, normal people are afraid that it is difficult to operate for a long time." Ma Wu directly said his feelings.

Although there seems to be no problem with doing it yourself, not everyone has their own physique, and this is for most people, not for themselves.

Five trucks lined up in a row, naturally Li Yuanji took the lead, there was no danger in the test site, and not many people dared to walk in front of Li Yuanji at this time, although according to the regulations, someone must walk in front.

Five trucks ran around the proving ground and finally stopped at the starting point.

A group of ministers jumped out of the truck one by one, and despite the fact that there were still many shortcomings, they still did not hesitate to praise themselves.

Even, the Ministry of Industry has already spoken, as long as the brake problem can be solved, when it can be built in batches, the Ministry of Industry will buy a batch first.

Fang Xuanling also said that he would urge the rubber mill to solve the problem of wheels as soon as possible, after all, this wear rate is still difficult to accept.

Nowadays, rubber is not cheap, mainly because the transportation distance is too long, and there is no train, which adds a lot of costs.

Every minister has his own things to say, his own questions, but no one thinks about being on time.

Obviously, they all experienced it and realized the role of trucks, such as Cheng Zhijie, and even looked forward to the retirement of the war horse, a truck can transport a lot of soldiers, and it is much safer than the war horse.

The most important thing is that they don't have to worry about it, they can sleep and rest on it, the fatigue of the march is reduced to a minimum, and in the same way, the troops can carry more supplies and supplies.

In the end, it was Li Yuanji who put forward suggestions for improvement, and at present, in addition to the problems raised by Jiang Tian himself, Li Yuanji can only mention two points.

One is the steering wheel, which has to find a way to make the operation more labor-saving, the other is to install a fixed seat to prevent the bumpy road from affecting the driving, and even install a seat belt to fix the driver.

Jiang Tian took note of Li Yuanji's opinion and said that he would solve it as soon as possible.

Although there were various problems, on the whole, the results of this test were very happy, and everyone saw what they wanted.
