"Our transportation market has huge potential." After walking through the grassland, we entered the mountains.

There are no highways yet, and the roads in the mountains are very difficult, but there are still a large number of vehicles walking on these roads.

Among them, most of them are Jiefang, Dongfeng, and there is a hanging bucket behind these vehicles, which is full of black coals.

This is a coal province, and there is black coal everywhere underground, which is mined and transported to various places to support the country's economic construction, so there is a large demand for transportation.

It is not enough to rely on railways, in the past, mainly by railways, but now, with the development of the country's economy, many collective enterprises have also increased the demand for coal, these enterprises have no ability to get train wagons, can only take the car transport.

Besides, the country's economic growth, and the problem of lagging railway capacity will become more and more prominent, so the lack of heavy trucks will become more and more serious.

Take the vehicle you see now, it is a full trailer method, with the main car in front and a trailer in the back, the main car pulls 15 tons, and the trailer pulls 10 tons, that is to say, a car pulls 25 tons of goods, which is already the top of the sky.

Of course, this is also an overloaded transport that seriously exceeds the limit.

The old liberation, CA10, although after several improvements, now the latest production model is CA10C, but only the maximum engine power increased from 95 horsepower to 110 horsepower, the maximum speed increased from 75km/h to 80km/h, and the fuel consumption per 100 kilometers was reduced from 29L to 25.8L. As for the most important load capacity index, it has been increased from 4 tons to 4.5 tons.

For a truck, this load capacity, that's a joke, a three horses can pull so much in the future, of course, in actual use, there is no overload.

If it was on the plains, maybe it could have been more loaded, but now, on the mountain roads, it is not easy.

In front, an old liberation car was humming and climbing up the hillside, its engine roared, and puffs of black smoke came out of the exhaust pipe, but the speed at this time was like a snail climbing.

It uses one gear, with the lowest gear getting the most traction.

Its speed is very slow, and behind, it is blocked by a row of cars, especially an EQ140 produced by the second automobile Dongfeng, using a diesel engine, several trials, and finally in a slightly wider place in front, the driver stepped on the accelerator and completed the overtaking.

"For passenger cars, diesel engines are an inevitable development direction, and the liberation car has been produced for more than 20 years, and it has not been modified, and it has fallen behind." Behind, the tank was also climbing up unhurriedly, and at the same time, Qin Zhenhua sighed.

Gasoline engines and diesel engines, even if the horsepower is the same, however, there is a big gap in performance.

When many people compare cars, they will only compare the data of horsepower, but they don't know that horsepower is related to the speed, the speed of the gasoline engine is high, the same 100 horsepower, the gasoline engine may be reached at the speed of 6,000 rpm and 7,000 rpm, but the diesel engine is reached at 2,000 rpm!

What does this mean?

Under the same conditions, the fuel consumption of the gasoline engine is far higher than that of the diesel engine, because its high speed is high, and the number of burns is more!

On the other hand, due to the large compression ratio of the diesel engine, it has a large torque, that is, a large force on the ramp.

"It is said that the liberation factory is also making improvements and intends to develop a new car, which seems to have been made clear, what is it called CA141."

Li Changjiang said there.

Hearing this, Qin Zhenhua also smiled helplessly, this little bit of caution is also interesting.

The old liberation is called CA10, and after a major change, there is another one called CA15, if it is named according to this, the next should be CA20.

However, Dongfeng Factory has built an advanced truck named EQ140, so the liberation factory will overwhelm others, if you call it 140, then I will call it 141!

From the naming, I don't admit defeat, and I hope that from the actual performance, there must be a huge improvement! Qin Zhenhua thought secretly in his heart.

However, this also reflects that on the other hand, there is competition, there will be progress, if there is only one car factory in the country, it is estimated that the old liberation can still produce for 20 years!

Qin Zhenhua thought so, and suddenly, Li Changjiang shouted: "Not good! ”

I saw that the old Jiefang, when he was about to climb to the top of the slope, suddenly, in front of the front of the car, there were puffs of white smoke, and the engine was boiling!

Long-term high-speed climbing, the requirements for power are very high, and now, when this old liberation is about to reach the end of victory, it is still defeated and can't climb!

Once the pot is boiled, the engine has to be high, and after the high temperature, the engine pulls the cylinder, and then scraps, waiting for overhaul!

So, after discovering the white smoke coming out of the water tank, the driver immediately stepped on the brakes and planned to stop.

The speed of the car was already slow, and when I stepped on the brakes, the car snorted and stopped there, and then, at a speed visible to the naked eye, the car began to retreat!

In the case of heavy load, it is difficult for the car to brake, and in the braking, it is not easy to prevent the slide, and the driver in front of him, obviously a novice, actually thinks that only a handbrake can be pulled.

The new heavy truck, the handbrake is also an air brake, direct brake, this kind of brake is very peculiar, usually there is air pressure, when the brake is no air pressure, so it is also called the air brake, so the advantage is that the car is out of gas, can immediately brake.

However, the ordinary liberation, Dongfeng, do not have this kind of braking system, they use the most ordinary air brakes, and the handbrake is just a brake pad on the transmission shaft.

This kind of load, this kind of slope, can't stop at all!

Experienced drivers will use the gear to pin the car for the first time, but now the engine is in a state of boiling, and it is inconvenient to turn off the engine directly, so all kinds of wrong operations make the car slide down upside down!

Originally, it was the Dongfeng car that was following it, and the people had already overtaken it in advance, which was considered to have escaped a catastrophe, and behind it was Qin Zhenhua's 80 tank!

The tank is relatively wide, so it is inconvenient to overtake, and because the other party is struggling to climb the slope, Qin Zhenhua and the others don't want to cause obstacles to the other party, so they simply follow behind, and this one will have an accident.

Don't follow a heavy truck uphill, it's a bloody lesson!

Seeing that the car began to slide, as long as it slipped down, it would be out of control, and there was no choice, Qin Zhenhua could only shout loudly: "Quick, turn the turret!" ”

The tank is an iron lump, it is not afraid of collision, in the tactics of the tank, there are even special collision tactics, but when the tank hits, the barrel cannot move forward!
