"Our transportation market has great potential." After walking through the grassland, we entered the mountainous area.
There are no expressways yet, and the roads in the mountainous areas are very difficult, but there are still a large number of vehicles walking on these roads.
Most of them were Jiefang and Dongfeng. There was a hanger behind these vehicles, and the inside was full of black coal.
This is the Coal Province, and black coal is everywhere underground. It is mined and transported to various places to support the country's economic construction, which has a large demand for transportation.
Relying on railways is not enough. In the past, it was mainly based on railways. However, now, with the development of the national economy, many collective enterprises have also increased their demand for coal. These enterprises do not have the ability to get trains, so they can only be
Take the motor transport.
Besides, the problem of national economic growth and lagging railway capacity will become more and more prominent, so the lack of heavy trucks will become more and more serious.
Take the vehicles I see now for example. They use a full trailer. There is a main car in front and a trailer behind. The main car is pulled up to 15 tons and the trailer is pulled up to 10 tons. That is to say, one car is pulled up to 25 tons.
Tons of goods are already at the top.
Of course, this is also a serious overload transportation that exceeds the limit.
Lao Jiefang, CA10, although it has been improved several times, the latest model produced is CA10C, which only increases the maximum engine power from 95 horsepower to 110 horsepower, and the maximum speed from 75km/h to 80km/h, 100 kilometers.
Fuel consumption has been reduced from 29L to 25.8L. As for the most important indicator of load capacity, it has been increased from 4 tons to 4.5 tons.
For a truck, this load capacity is a joke. In the later generations, a three-horse can pull so much. Of course, there is no one that is not overloaded in actual use.
If it was on the plain, you might be able to install more, but now, on the mountain road, it is not easy.
In front, an old Jiefang was climbing up the hillside with a groan. Its engine roared, and black smoke came out of the exhaust pipe, but the speed was the same.
Snails crawl.
It uses first gear, and the lowest gear can obtain the highest traction.
Its speed is very slow, and behind it, a row of cars were blocked, especially an EQ140 produced by Erqi Dongfeng, which uses a diesel engine. After several tests, the driver finally stepped on a slightly wider place in front.
He took the accelerator and completed the overtaking.
"For passenger cars, diesel engines are an inevitable development direction. Jiefang car has been produced for more than 20 years and has not been modified. It is already out of date." Later, the tanks were also climbing upwards slowly.
At the same time, Qin Zhenhua sighed.
Even if the horsepower of gasoline engines and diesel engines have the same horsepower, there is a big gap in performance.
Many people only compare horsepower data when comparing cars, but they don’t know that horsepower is related to the speed. The gasoline engine has a high speed. The same 100 horsepower, the gasoline engine may be at a speed of 6,000 rpm or 7,000 rpm.
It is achieved by reaching the top, but the diesel engine can reach it in two thousand rotations!
what does that mean?
Under the same conditions, the fuel consumption of the gasoline engine is far greater than that of the diesel engine, because it rotates at a high speed and burns more times!
On the other hand, due to the large compression ratio of the diesel engine, it has a large torque, that is, it has a large force on the ramp.
"It is said that the Jiefang Factory is also improving, and it plans to develop a new car. It seems that it is already clear, its name is CA141."
Li Changjiang said there.
Hearing this, Qin Zhenhua smiled helplessly. This little thought was also interesting.
Lao Jiefang is called CA10, and after the major modification, there is another one called CA15. If you name it according to this, the next one should be CA20.
However, Dongfeng Factory built an advanced truck, named it EQ140, so Jiefang Factory has to overwhelm others. If you call 140, then I call 141!
In terms of naming, I don’t admit defeat, and I hope that there will be a huge improvement in actual performance! Qin Zhenhua thought secretly in his heart.
However, this also reflects the other hand that only with competition can there be progress. If there is only one automobile factory in China, then Lao Jiefang will probably be able to produce for twenty years!
Qin Zhenhua thought so, and suddenly, Li Changjiang shouted: "Not good!"
I saw that the old Jiefang was about to climb up the top of the hill, suddenly, streams of white smoke came out in front of the front of the car, and the engine was boiling!
Long-term high-speed climbing requirements for power are very high. Now, when this old hand is about to reach the end of victory, it still loses and can't climb anymore!
Once the pot is turned on, the engine will have a high temperature. After the high temperature, the engine will be pulled and then scrapped, waiting for overhaul!
So, after finding white smoke coming out of the water tank, the driver immediately stepped on the brakes and planned to stop.
The car was already slow. When the brakes were put on, the car stopped there with a thud. Then, at a speed visible to the naked eye, the car began to retreat!
It is difficult to brake the car under heavy load, and it is not easy to prevent slope slipping while braked. The driver in front of him is obviously a novice and actually thinks that just pulling the handbrake is enough.
The new heavy truck uses air brakes, which directly brake wheels. This kind of brake is very unique. It usually has air pressure, but there is no air pressure when the brake is braked, so it is also called air-cut brake. This advantage is that the car is exhausted and can brake immediately.
stop.
However, ordinary Jiefang and Dongfeng do not have this kind of brake system. They use the most ordinary air pressure brakes, and the handbrake is just a brake pad on the transmission shaft.
This load and this slope can't stop at all!
Experienced drivers will use gears to pin the car as soon as possible, but now the engine is in a state of boiling pot and it is not convenient to turn off the engine directly. Therefore, various wrong operations have caused the car to slip backwards!
Originally, the Dongfeng motel was following it. The person had already overtaken in advance and was considered to have escaped. The one behind was Qin Zhenhua and his 80 tank!
The tank is relatively wide, so it is inconvenient to overtake. Because the opponent has difficulty climbing the hill, Qin Zhenhua and others do not want to cause obstacles to the opponent, so they simply followed behind. Something happened after following.
Don’t follow the heavy truck when going uphill. This is a bloody lesson!
Seeing that the car began to slip, as long as it slipped down, it would be out of control. Without any choice, Qin Zhenhua could only shout loudly: "Hurry up, turn the turret!"
Tanks are just iron lumps and are not afraid of collisions. In tank tactics, there are even special impact tactics. However, when tanks hit, the gun barrel cannot move forward!
