Chapter 2667: Research and development of Haihe Automobile Plant

R & D department? Qin Guan knew that the previous vans were made by Heribala and later handed over to the Haihe Automobile Factory for production. Now, the Haihe Automobile Factory now relies on the technical strength of the Northern Heavy Truck Factory. Do you make some advanced products yourself?
what is it then?
"This is the engine R&D department." Director Zhang took Qin Guan and walked in. You can see that the workers here are wearing white lab coats, which is in sharp contrast with those in work clothes outside. They come and go. , I didn't have any curiosity because of Qin Guan's arrival.
"What is the engine being developed?" Qin Guan asked factory manager Zhang.
"Our current engine is still using carburetor, which has high pollution and high fuel consumption. According to the general plant on the grassland, the engine must enter the era of electronic injection. Therefore, we are developing electronic injection engines here. Its biggest feature is that it can use a computer to control the fuel injection volume and fine-tune it."
Cars and vans use gasoline engines, which need to atomize gasoline into fine particles, which enter the cylinder during the intake stroke. Since gasoline engines began to produce, they use carburetor to atomize. This device Quite simply, the efficiency of atomization is not high, and the use of mechanical mediation can be said to be unable to meet the needs of the development of the times.
In the future, it will inevitably transition to the era of electronic injection, using electronic systems to create the atomization effect of gasoline and control the amount of fuel injection, which is more precise and more efficient.
For example, when a car is going uphill, drivers like to step on the accelerator. Only by stepping on the accelerator and listening to the roar of the engine will they feel enjoyable. In fact, this kind of operation is not good, just look at the black smoke at the tail. As you can see, most of the fuel is not completely burned and is wasted, polluting the environment, fuel consumption is still high, and it will also cause serious carbon deposition.
In the case of an EFI engine, everything is judged by the computer. The engine has its own brain, which is the ECU. If the engine is monitored to be overloaded, it will not increase the fuel injection volume according to the driver’s instructions on the accelerator. There will be one's own judgment to keep it in the best burning state at all times.
With the development of technology, carburetor vehicles will eventually be eliminated, and all cars will enter the era of computer control. At that time, Han Guo has mature technology and can produce it at any time.
Qin nodded his opinion: "Yes, investing in advanced engines is our direction of development. Haihe Automobile Factory's research direction is good. Wait, what is this, turbine?"
At this time, everyone was standing in front of a table, on which was a model displayed. When he saw the circular device between the exhaust duct and the intake duct, Qin Guan could guess what it was. Something comes.
"Yes, one is electronic injection technology and the other is turbocharging. These are the future development directions." Director Zhang said: "We are currently developing turbocharged gasoline engines and have applied for many patents. ."
Qin nodded his opinion: "Yes, yes, the development of Haihe Automobile Plant is worth learning from the entire system and worthy of praise from the head office!"
Speaking of it, Qin Guan is the great leader, and Qin Guan’s praise is truly tangible and worthy of the pride and pride of the entire company.
What Qin Guan praised was of course their awareness. We must do scientific research, and after we do it, we must apply for patents to block the way for others!
Qin Guan had only asked Heribala to register patents for all the technologies before, so that they could maintain the advanced nature of the technology at all times. Unexpectedly, this is also the case here.
Nowadays, turbocharged engines have not become popular in the world. Even in the era of 2020, there are still many media professionals who have cited many years of maintenance experience, saying that turbocharging is unreliable and self-priming. the best!
These are people who like to sleep on the basis of their past achievements. They always remember the past and feel that the past is the golden age. Such people will not make progress.
Qin Guan knew the development of history. Those who insisted on the self-priming camp one by one, didn't they all fall into the embrace of turbocharging in the end?
With the same displacement, the power is sufficient, the torque comes early, and the speed is fast. It can be said that as long as you have driven a turbocharged car and want to start self-priming, you can no longer adapt. In a common saying, it is too fleshy. Up.
Self-priming is good. Then we have to add a word in front of it, that is, large displacement self-priming. Only a large displacement can reflect the strong power and acceleration linearity from the suction. An ordinary 2.0 self-priming can boast what is better than 1.5T strong? Also talk about maintenance, and what turbines are easy to break. The turbines of large trucks have a history of decades, and they have the same life span as the engine.
Now, our side is engaged in research and development in this direction and has to register all patents. In the future, other manufacturers will find that the road is blocked. They cannot find another way. They can only buy their own. It will inevitably become the world's automotive technology powerhouse, and there is no need to fantasize about using electric vehicles to overtake corners. The result is companies that cheat subsidies.
Qin Guan affirmed their engine, but after a closer look, he still found some problems: "Is this kind of engine yours on a van?"
Director Zhang smiled awkwardly: "Yes, we already know the technology at hand, it is the engine of this van, so all improvements are based on the van."
The 1.0 van engine is changed to electronic injection and turbines are added, so that more power can be squeezed out, but this is not the most optimized. After all, the future development trend of vehicles is becoming more and more large. This kind of power Not enough.
"I suggest that the factory develop a 1.5-displacement engine by itself." Qin Guan said: "In the future, Haihe Automobile Factory will have a suitable engine if it wants to build a car with a larger body or an off-road vehicle."
1.5T is enough for medium-sized cars. If you think 2.0 is too big, you should increase the displacement first to reach the level of 1.5T.
"Yes, since President Qin pointed out the direction for us, we will start this kind of project in the later stage." Director Zhang said: "Now, please come here and take a look at our new car project."
We have been working this 1.0 engine, also for supporting new car projects.
In addition to researching and developing engines, it is also necessary to develop complete vehicles. After all, Haihe Automobile Factory manufactures complete vehicles.
Opening the door connecting the two R&D rooms, Qin opened his mouth when he saw a car on display in the entrance hall. What, little QQ?
