Super Weapon Swap System

While talking, Sandra took Qin Guan to the outside of the specific R & D booth. On this booth, there was a 2.0T engine with the largest installed capacity.

"In order to reduce its power hysteresis, we have added an electric turbine at its air inlet. Before the exhaust turbine works, it can improve the power from 1200 revolutions," Sandra said.

Generally, the idle speed of the engine is 500 or 600 revolutions, and as long as you slightly step on the accelerator, it can exceed 1000 revolutions. This is also the speed at which the car starts normally, which means that as long as the car starts, it is already in the power explosion range.

Qin Guan seriously looked at the electric turbine he joined later, with some questions in his eyes: "electric turbine? Won't it have a reaction?"

When Qin Guan asked this, Sandra looked surprised: "President Qin, you have surprised me more than once. You are obviously a layman. How can you say such an expert?"

Qin Guan is an expert and a surprising expert. Only an expert can ask such a question. The electric turbine works well before the exhaust gas turbine works, which can reduce the hysteresis of the turbine. However, it is not easy to make it work normally!

Qin Guan learned it when he was in parallel time and space. After all, as long as he is a man, he must love the car. Many people will think of their own ways to improve power. Some brush the car's ECU, and some buy an electric turbine to hang inside. In this way, listening to the roar of the turbine is very enjoyable. In fact, the power will decline instead of improving.

Why?

Of course, it was counterproductive.

Turbocharging, the speed of the impeller is often tens of thousands of revolutions, or even tens of thousands of revolutions. Only such power can pump enough air, while the electric turbine has only a few thousand revolutions, and the highest is only ten thousand revolutions. It originally wanted to pump more air, but in fact, when the turbine works, because the speed is too low, Instead, it will hinder the entry of air. When the engine inhales, reduce the oxygen content, and the power of the engine will decrease.

Therefore, those who boast about adding electric turbines to their cars feel good about themselves. As long as they have a sports car in their heart, even a small QQ can feel off the track.

"We have studied for a long time. The current car, with a 12 volt circuit, can't supply the electric turbine. If you want the electric turbine to work, the car's circuit should turn to 48 volts." he ribala explained aside: "therefore, the electric turbine used in this engine is 48 volts."

The higher the voltage, the more energy will be provided. In the automobile circuit, passenger cars are 12 volts and commercial vehicles are 24 volts. Now, if you want to use the electric turbine for the engine, you need a 48 volt circuit, which makes them a little embarrassed. If it is popularized, how can the automobile circuit power it?

Unless the entire vehicle uses a 48 volt power supply system, and this will be greatly restricted. The automotive circuit, which is a whole, has countless suppliers to change, and they may not be able to support it. There are already examples in this regard.

Just after entering the 1990s, the world's major automobile enterprises have foreseen that with more and more on-board appliances, the existing 12 volt power supply system will eventually be overwhelmed. They plan to implement higher voltage standards to "reduce the burden" for the automobile circuit system, which is the 42 volt system.

However, up to now, only in the past two or three years, the promotion has ended in failure. If this 42 volt system is used to comprehensively replace the current 12 volt system, the complexity and cost involved are too high, and the resistance to promotion is too large. All supporting manufacturers prefer to optimize the existing 12 volt system rather than change the voltage.

Therefore, the promotion failed this time. Now, it is even more difficult for our side to increase to 48 volts. As we are an emerging manufacturer, we are dividing the market share of existing manufacturers. They are highly vigilant towards our side. How can they support our change?

The question is not whether our technology is not advanced, but whether there are enough common to support it.

Therefore, although this system is under development, there are still many problems if you want to be really practical.

Hearing their introduction, Qin Guan did not care, and immediately gave them an idea: "since we are going to use such a system, why don't we do more?"

Do more? People familiar with Qin Guan know that his strategic vision will be reflected again. Now, he RI Bala even took out a small book and began to record it.

"We know that today's vehicles are very fuel-efficient under high-speed conditions. The main thing is urban roads, starting and stopping. In this case, the fuel consumption is quite high. Our next goal is to reduce the fuel consumption under this condition and achieve the goal of 4 liters per hundred kilometers," Qin Guan said.

Regardless of the working conditions and fuel consumption, that is, playing hooligans. Almost any vehicle, walking and stopping in the urban area, consumes about twice the fuel consumption of high-speed vehicles. Frequent starting and parking consume energy. Now, there is no good way to change it. The smart thing is to automatically start and stop the system, turn off the engine after stopping, even wait for a traffic light for one minute, It will also shut down to reduce fuel consumption.

However, this system thinks itself smart, because the first thing most people do after getting on the bus is to turn off the system. In addition to the jitter caused by frequent startup, there is no way to bring air conditioning after flameout. How can this be accepted? In hot cities, the absence of air conditioning will definitely increase road rage.

If we can reduce the fuel consumption under the working conditions of the city, there is no doubt that there will be more market demand for cars. After all, no matter which manufacturer can't do this now, and many users are mainly urban cars.

"The key of this system is a special 48 volt motor, which can directly replace the functions of motor and generator. In other words, it can not only drive the engine, but also act as a generator to generate power for the vehicle, but also help the vehicle achieve fuel-saving effect under starting, braking, taxiing and other working conditions." Qin Guan began his introduction.
