Super Weapon Exchange System

While talking, Sandra took Qin Guan and came outside the specific research and development platform. On this booth, there was a 2.0T engine with the largest installed capacity.

"In order to be able to reduce its power lag, we added an electric turbine to its air intake. Before the exhaust gas turbine works, it will act to increase the power from 1200 rpm. "Sandra said.

The normal engine speed is five or six hundred revolutions when idling, and as long as you slightly step on the accelerator, it can exceed one thousand revolutions. This is also the normal starting speed of the car, which means that as long as the car starts to start, it is already in power. The outbreak interval.

Qin Guan looked at this newly added electric turbine seriously, with some questions in his eyes: "The electric turbine? Will it be counterproductive?"

Qin Guan asked this question, but Sandra showed a surprised look: "Mr 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 things as the electric turbine, which sounds good. It works before the exhaust turbine works, so as to reduce the lag of the turbine. Sex, but this thing, it is not easy to make it work!

Qin Guan also learned from the parallel time and space. After all, as long as a man is a car, many people will think of their own ways to improve their power. Some are brushing the ECU of the car, and some are buying an electric turbo hanger. , Listening to the whistle of the turbine in this way feels very enjoyable. In fact, the power has not improved, but will drop.

Why is this?

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 with this kind of power can enough air be blown in, while the electric turbine only has a few thousand revolutions, and the highest speed is no more than 10,000 revolutions. , It originally wanted to blow in more air, but in fact, when the turbine is working, because the speed is too low, it will hinder the entry of air. When the engine is inhaled, the oxygen content will be reduced. Instead, the motivation has dropped.

Therefore, those who boast about adding electric turbines to their cars all have a good sense of self in their hearts. As long as they have a sports car in their minds, even a small QQ can feel off the track.

"We have studied for a long time. The current car, the 12-volt circuit cannot supply an electric turbine. To make the electric turbine work, the car's circuit must switch to 48 volts." Heri Bara explained on the side. Said: "So, the electric turbine used in the current engine is 48 volts."

The higher the voltage, the more energy is naturally provided. In the circuit of automobiles, passenger cars are all 12 volts, and commercial vehicles are all 24 volts. Now, if you want to use electric turbines for engines, you need 48. Volt's circuit, which makes them a little bit embarrassed. If it is promoted, how should the car circuit power it?

Unless the entire vehicle uses a 48-volt power supply system, and this, it will be subject to a big restriction. The car circuit is a whole, and there are countless suppliers that have to change. They may not be able to support it. In this regard, there is already a precedent.

Just after entering the 1990s, the major car companies in the world have already foreseen that with more and more on-board electrical appliances, the existing 12-volt power supply system will eventually be overwhelmed. They plan to implement higher voltage standards. To reduce the burden on the car's electrical system, this is the 42-volt system.

However, it has only been two or three years since the promotion has ended in failure. If this 42-volt system is used to completely replace the current 12-volt system, the complexity and cost involved are too high, and the resistance to promotion is too great. The supporting manufacturers would rather optimize the existing 12-volt system than change the voltage.

Therefore, this promotion failed, and now, if we want to increase to 48 volts, it is even more difficult. Since we are a new manufacturer, we are originally dividing the market share of existing manufacturers. They maintain a high degree of vigilance towards their own side, how can they support this change of their own side?

The question is not whether one's own technology is not advanced, but whether there are enough common ones to support it.

Therefore, although this system is under development, there are still many problems if it wants to be truly practical.

Hearing their introduction, Qin Guan didn't care, and immediately gave them an idea: "Since we plan to use such a system, why don't we do more?"

Do more? Anyone familiar with Qin Guan knows that his strategic foresight will be reflected again. Now, Heribala even took out a small notebook and began to record it.

"We know that today's vehicles are already very fuel-efficient under high-speed conditions. The main ones are urban roads, starting and stopping. In this case, the fuel consumption is quite high. Our next goal is this Reduce fuel consumption under working conditions to reach the goal of 4 liters per 100 kilometers." Qin Guan said.

Regardless of the working conditions and the fuel consumption, it is playing rogues. Almost any vehicle, stop and go in the urban area, is about twice the fuel consumption of high-speed. Frequent starting and stopping all consume energy, and now, it is also There is no good way to change it. The one who thinks it is smart is to automatically start and stop the system. When it stops, it will turn off. Even if it waits for a one-minute traffic light, it will turn off to reduce fuel consumption.

However, this system is self-conscious, because the first thing most people do after getting in the car is to turn off the system. In addition to the jitter caused by frequent startup, there is no way to take it after the flame is turned off. Air-conditioning, how can this be acceptable? In a hot city, the absence of air-conditioning will definitely increase road rage.

If the fuel consumption under the working conditions of this city can be reduced, then there will be no doubt that there will be more market demand for cars. After all, no matter what manufacturer, it is impossible to do this now, and many users just use the city Car-based.

"The key to this system is a special 48-volt motor. This is a special motor that can directly replace the functions of a motor and a generator. That is to say, it can drive the engine to run or act as a generator. Generating electricity for vehicles can also help vehicles achieve fuel-saving effects under starting, braking, and coasting conditions." Qin Guan started his own introduction.
