"What are you going to do next after mass production of DSP chips?" asked Mr. Liang: "We are currently lacking in all aspects."
Electronic technology has developed greatly in recent years, but China has lagged behind for various reasons. Therefore, now we are catching up, and there are many aspects that require investment. With DSP chips, should we build CPUs next?
"We are still considering the next development direction." Wang Xiaoqiang said: "We really want to launch the CPU project immediately, but if this happens, all our profits will be invested in, and we may even continue to make loans."
Now it is not the future generations. The country has fully supported it and has the support of the country. As long as those who polish chips and pretend to be fake, they will definitely make a name for themselves. Now, all walks of life in the country need money, but the country can invest very little.
The investment in chips is too large, so it is not unreasonable to cut off super-large integrated circuit projects by computers. The investment is too large and the results are slow.
Wang Xiaoqiang wished he would launch the CPU project immediately, but Wang Xiaoqiang knew in his heart that this project was not simple. If he started, he would not know how much money he would spend in. Although a machine factory was behind him, if so,
Wang Xiaoqiang also felt a little embarrassed because he dragged down the Yimai Factory. After all, Qin Zhenhua has helped him too many times. Now that he has already gotten on the right track, he can't keep asking for money from Yimai Factory.
"Then, maybe you can make a smaller one first." Qin Zhenhua pondered there, and then said: "For example? Create the ECU first, this project will definitely have a future than DSP."
Just one word? The meaning is only a small difference? This ECU is the abbreviation of Elecmal Control Unit, which is also called "traffic computer". Is it a microcomputer used to control cars?
It has the most basic structure of a computer—microprocessor (CPU), memory (ROM, RAM), input/output interface (I/O), analog-to-digital converter (A/D), and large-scale integration of plastic shaping, drivers, etc.
Circuit.
"At present? The engines of automobiles are changing from carburetors to electronic injection, and many mechanical structures have been replaced by electronic structures." Qin Zhenhua said: "The demand for chips that control engine operation will also increase? Although we are in China
The cars currently produced are still carburetors? But I believe? They will definitely be replaced by electronic injection systems in the future? The market prospects in this area are very broad, and they are closely related to our machine factory."
After the invention of the gasoline engine, the carburetor came out? It was like a small funnel? It was responsible for gasifying the gasoline and mixing it with the air into a combustible mixture in a certain proportion? It entered the cylinder in a timely and appropriate amount.
So far, the carburetor has developed to a perfect state. It is low in cost and high reliability? It is easy to repair and maintain, but the carburetor is also defective. It is a fixed oil supply method, and it starts at a cold car and runs at idle speed.
In acute acceleration or low air pressure environments, oil supply cannot fully meet the engine's operation needs, resulting in black smoke, incomplete combustion and insufficient horsepower.
In this era, when cars in the accelerator, they will inevitably emit black smoke. This is why.

Electronic injection devices began to appear in the 1940s. Mercedes-Benz applied this engine electronic injection technology to the engine, but it was not perfect at that time. Until 1967, the D-type electron injection developed by Porsche, Germany.
The devices were subsequently used in German cars such as Volkswagen. After the 1980s, more and more cars equipped with electronic injection devices in the West were equipped with more and more.
Take the current situation as an example. The United States is already 100%, while Germany is more than 90%. It can be said that carburetors have been eliminated.
What about domestic cars? They are still mainly carburetors, and the electronic injection system is completely blank. If they are created, the future market will not be tens of thousands, hundreds of thousands, but millions, thousands.
There is a demand of more than 100 million or more.
After the electrospray replaced the carburetor, many veteran drivers missed the direct feeling of the carburetor, because the electrospray is electronically controlled. For example, starting from the beginning, even if you step on the accelerator to the bottom, the computer will control it. It is impossible.
Increase the amount of oil to the maximum according to your requirements, so it has attracted dissatisfaction from many veteran drivers, thinking that the electric injection engine is boring. This is of course a misunderstanding. The electronic injection system has too many benefits, so it is precisely controlled to enter the cylinder.
Fuel, which obtains an air-fuel ratio that meets the requirements, is quite stable under various operating conditions, increases the engine's power and reduces the engine's fuel consumption.
Of course, this is on the car. When it comes to the diesel engine, it can also push the diesel engine to electronic control by combining with the high-pressure common rail fuel system used in the diesel engine, which can further increase the engine's power.
The first thing that needs to be used is naturally a tank diesel engine!
If you want to say that the most advanced technology in the world is naturally the engine used for tanks, which integrates the world's most advanced technology, such as the turbocharger system. When people are still sticking to the naturally aspirated engine in 2020, they will still be stuck in the naturally aspirated engine.
Tank engines had fully entered turbineization in the 1980s.
However, turbocharger only solves one problem, which is to inject more air into the engine and let it participate in combustion, but what about the injected fuel?
The traditional diesel pump relies on the form of a plunger. One cylinder is equipped with a plunger pump and uses mechanical oil supply. In essence, it has the same defect as the carburetor. The fuel injection is limited by the engine. Specifically, the engine
The faster the rotation speed, the faster the plunger pump moves, the greater the internal pressure, and the more fuel it injects out, so that the combustion at low speeds is very poor.
It is of great benefit to keep the fuel injection pressure constant at all times without being restricted by the speed. In this way, when will the fuel be injected, how much fuel is injected, or even after injection, it will be a secondary injection.
All of them need to be controlled by computers.
ECU is of great use in this regard. If this system is available, Qin Zhenhua is sure that it is definitely not difficult to increase the power of the tank engine to 1,500 horsepower, and it will save fuel, with a power of 1,500 horsepower.
Hundred horsepower, but burning oil is the same as the fuel consumption of 1,200 horsepower!
Qin Zhenhua introduced these things, and Wang Xiaoqiang was naturally very interested, but he shook his head helplessly: "I am not familiar with this field."
Wang Xiaoqiang is very self-aware and should not easily dabble in areas that he is not familiar with, otherwise it will easily waste a lot of investment.
"Yes, you are not familiar with this, but my sister-in-law is familiar with it."
