When Steyer engine was introduced, the corresponding WD615 engine technology was introduced. The engines of civilian vehicles in major Eastern countries were almost all developed based on this power. Now, the cars in Steyer factory are now
The factory has gone bankrupt, but its descendants have been continuously developed in the Eastern powers. This power system is constantly improving. Now it has even expanded the cylinder to 13 liters, and the power has also increased to more than 500 horsepower.
At this time, when he heard Wang Erzhu say this, Qin Zhenhua said: "What is the assembly quantity of the engine of Doyz?"
At the beginning, Mercedes-Benz heavy trucks produced by the first machine factory were divided into three power systems. The original imported Mercedes-Benz engine sold the best. The air-cooled Deutz I used was slightly lower. The version of Steyr engine was used
, the cheapest sold, among which the largest shipment is equipped with air-cooled Deutz engines. After all, most of the trucks produced by the first machine factory are military, and military trucks are a large market, and for military use
For trucks, when using air-cooled engines, there is no need to worry about leaking coolant, so it is very marketable.
However, air-cooled engines also have many weaknesses. For example, the temperature of air-cooled engines is not easy to control and the heat dissipation is difficult. Therefore, Deutz, who has been studying air-cooled engines, has also been replaced by water-cooled engines.
The cylinder bore is still 132 mm, and this kind of engine is very popular. It is even attacked by a light tank newly developed by the first machine factory, which determines to improve performance and meet the standards for use of tank engines.
However, it seems that it is not that popular in cars.
"The technology of the Deutz engine is also very good. However, the Deutz engine in our brother factory is mainly military, and the fuel consumption is not excellent. I heard that FAW is discussing cooperation with Deutz and introducing
The new generation of Deutz automotive engines is more fuel-efficient. For us, it is the most suitable for purchasing this kind of engine. After all, over the years, this kind of engine has left a very good impression in the hearts of users." Wang Erzhu
Said.
Commercial vehicles are different from military use. The first thing to pay attention to is fuel consumption. For freight drivers, fuel consumption is already an important expense. After all, there is only so much freight costs. The lower the fuel consumption, the more you earn.
After hearing Wang Erzhu say this, Qin Zhenhua nodded. He knew that Wang Erzhu was right. Users have inertia. Since they already think that some kind of engine is good, they will focus on this aspect when choosing.
"Actually, natural gas has begun to become popular now." Wang Erzhu said: "Many cars have started to use natural gas. In terms of commercial vehicles, if natural gas is used, it can save about half of the fuel costs, so our model
The new heavy truck will also develop a natural gas version in the future.”
The natural gas used in the car is G, and the gas tank is still gas, so it is less difficult. Commercial vehicles use LNG, liquefied natural gas, and the gas tank is stored in the gas tank. With the same volume, more fuel can be stored.
, Therefore, it can meet the needs of long-distance truck transportation. However, this thing is still a new thing, and how to layout it is a big problem, so they plan to be a future research project.
After hearing Wang Erzhu's words, Qin Zhenhua continued to nod. He didn't understand these things very well. He just needed to believe Wang Erzhu's vision.
"Over the years, the country has become increasingly strict in the control of air pollution. It is difficult for diesel engines to improve emission standards, but it is easy for natural gas. After all, natural gas has always been very pure and there are very few pollutants burned out."
Wang Erzhu said: "We believe that there will be more and more natural gas trucks in the future."
After saying this, the engine has been preheated. Seeing the water temperature gradually rise, Wang Erzhu said: "Director Qin, you can try to start the car."
So, Qin Zhenhua subconsciously stepped on his left foot and found that he had stepped on it for nothing. Then he realized that there was something wrong. So he smiled and began to push the gear shift handle with his right hand.
Puff, with a sound of air pressure assisting, the gear shifted over, and a D1 signal was displayed on the instrument panel. Qin Zhenhua released the handbrake and then gently stepped on the accelerator pedal.
When I first started working on AMT, the program optimization was not enough, so it was very difficult to start. Either I stepped on the accelerator and didn't leave, or the car jumped up directly, which made people very uncomfortable. Even if it was a Mercedes-Benz heavy truck, I tried automatic transmission in the early stage.
At that time, the clutch pedal was also retained, which was used for use when starting.
Now, when he stepped on the accelerator pedal, the car's engine began to accelerate and started smoothly in the humming roar.
Since there is only the front of the car and the engine is full of power, it is easy to cause too much torque output when starting. Even if it starts manually, it is easy to cause the front of the car to rise. For heavy truck drivers, these are all
It is common, because of this phenomenon that when they are at the toll station, they can use this professional method to skip the pound and reduce their weight. If they don’t jump the pound when driving a heavy truck, it’s not the same
Qualified driver.
Now, the starting point of this car is very stable, and you can feel the jumping of the front of the car. It can be seen that after several years of running-in, this software has finally been perfected, and Qin Zhenhua is very satisfied.
He continued to step on the accelerator, and the familiar sound of air pressure came from the clutch, and the gears began to switch, three and five gears, constantly improving.
For heavy trucks, the power is quite abundant, and now there is only the front of the car, so the car doesn't need to shift gears one by one, just jump to lift the gears up. During the shifting process, the car has a little bit of it.
It's intrusive, but it's totally acceptable.
"No, it's really good." Qin Zhenhua said, stepping on the accelerator and stepping on the accelerator to the bottom. As the engine roared, the transmission began to downshift again. It was indeed smart enough!
If you want to speed up the car, you can continue to upgrade the gears. However, if you want to speed up more vigorously, you have to downshift. Many sedans also need to downshift when overtaking and increase the speed. This is this
Truth believing, this can ensure sufficient traction. Now, Qin Zhenhua stepped on the accelerator to the bottom, and the gearbox understood his intentions and lowered the gear, which was quite good.
"Of course, the performance of the debugging of Baozhen and his company is absolutely excellent," said Wang Erzhu.
