"After you are mass-producing DSP chips, what are you going to do next?" Liang Lao asked, "At present, we are very lacking in all aspects." ”

Electronic technology has developed a lot in recent years, but the country has lagged behind for various reasons, so now to catch up, there are many aspects that need to be invested, with DSP chips, next, do you want to engage in CPU?

"We are still considering the next development direction." Wang Xiaoqiang said: "We really want to start the CPU project immediately, but if this happens, all our profits will be invested, and we may even continue to take out loans." ”

Now is not the next generation, the state fully supports, there is the state as the backing, as long as it is not those who polish the chip and pretend to be deceitful, it will definitely be able to make a name, now, all walks of life in the country need money, the country can invest very little, and the chip, the investment is too large, so the computer to cut the VLSI project, it is not unreasonable, the investment is too large, the effect is slow.

Wang Xiaoqiang can't wait to start the CPU project immediately, but Wang Xiaoqiang also knows in his heart that this project is not simple, if he starts it, he doesn't know how much money to throw into it. Although there is a machine factory behind him as a strong backing, if it drags down a machine factory, Wang Xiaoqiang also feels a little embarrassed, after all, Qin Zhenhua has helped him too much, and now that he is on the right track, he can't always reach out to a machine factory to ask for money.

"Then, maybe we can make a little bit smaller." Qin Zhenhua pondered there for a while, and then said, "For example? Let's get the ECU out first, this project is definitely more promising than DSP. ”

Just one word? Is that just a little bit of meaning? This ECU? It is the abbreviation of Elecmal Control Unit, that is, electronic control unit, which can also be called "trip computer". Is it a miniature computer used to control a car? 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 integrated circuits such as shaping and drivers.

"For now? The engine of the car is changing from carburetor to electronic injection, a lot of mechanical structure? has been replaced by an electronic structure. Qin Zhenhua said: "The chip that controls the operation of the engine? Will the demand also increase? Although the cars currently produced in our country are still carburetors? But I believe? Will it definitely be replaced by electronic injection systems in the future? The market prospect in this area is very extensive, and it is also closely related to our machine factory. ”

After the invention of the gasoline engine, the carburetor followed? Is it like a small funnel? Responsible for gasoline gasification? And mix with air in a certain proportion to form a combustible mixture? Enter the cylinder in a timely and appropriate amount.

By now, the carburetor has been developed to perfection, it is low-cost and reliable? It is easy to repair and maintain, but the carburetor is also defective, it is a fixed way of oil supply, in the cold car start, idle operation, rapid acceleration or low pressure environment, the oil supply can not fully meet the operation needs of the engine, resulting in black smoke, incomplete combustion and insufficient horsepower.

This is the reason why cars in this era must emit black smoke when they step on the accelerator.

The first URL

Electronic injection device began to appear in the forties, when Mercedes-Benz applied this engine electronic injection technology to the engine, but it was not perfect until 1967, the D type electronic injection device developed by the German Porsche company, and then used in German cars such as Volkswagen. After entering the eighties, there were more and more cars equipped with electronic injection devices in the West.

For now, the United States is already 100 percent, Germany is more than 90 percent, so to speak, the carburetor has been eliminated.

What about domestic cars? It is still based on carburetors, and the electronic injection system is completely blank, if you make it out, then the future market will not be tens of thousands, hundreds of thousands, but millions, tens of millions or even more than 100 million demand.

When the EFI replaces the carburetor, many old drivers miss the direct feeling of the carburetor, because the EFI is electronically controlled, such as starting, even if you step on the accelerator to the end, the computer will control, it is impossible to increase the oil volume to the maximum according to your requirements, so it has attracted a lot of old drivers who are dissatisfied, feel that the EFI engine is boring, which is of course a misunderstanding, the benefits of the electronic injection system are too many, accurately control the fuel entering the cylinder, obtain the air-fuel ratio that accurately meets the requirements, and are quite stable under various working conditions. The power of the engine is increased and the fuel consumption of the engine is reduced.

Of course, this is on the car, and when it comes to the diesel engine, with the high-pressure common rail fuel system used for the diesel engine, the diesel engine is also pushed to electronic control, which can improve the power of the engine even more.

The first thing that needs to apply such a system is, naturally, the tank diesel engine!

To say that the world's most advanced technology, of course, is the engine for tanks, which integrates the world's most advanced technology, such as turbocharging systems, when in 2020 there are still people clinging to the naturally aspirated engine, tank engines in the eighties of the twentieth century, has fully entered the turbo.

However, turbocharging solves only one aspect of the problem, which is to blow more air into the engine and let it participate in the combustion, but what about the injected fuel?

The traditional diesel pump, relying on the form of a plunger, a cylinder with a piston pump, the use of mechanical oil supply, in essence, and carburetor has the same defects, fuel injection is limited by the engine, specifically, the faster the engine speed, the faster the piston pump moves, the greater the internal pressure, the more fuel is injected out, so that the combustion at low speed is very poor.

If you can not be limited by the speed, so that the tank diesel engine injection pressure is kept constant at all times, it is a great benefit, in this way, when to inject fuel, how much fuel to inject, and even after the injection feels that it is not enough, and then a secondary injection, it all needs to be controlled by the computer.

ECU is very useful in this regard, if there is such a system, then Qin Zhenhua is sure that it is definitely not difficult for him to increase the power of the tank engine to 1,500 horsepower, and it will also save fuel, the power is 1,500 horsepower, but the fuel consumption of burning oil is the same as that of 1,200 horsepower!

Qin Zhenhua introduced these, 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 if he is not familiar with the field, he should not easily dabble in it, otherwise, it will be easy to waste a large amount of investment.

"That's right, you're not familiar with this, but my sister-in-law is familiar with it."
