reborn industrial empire

Another problem with methanol fuel is the legendary poisonous problem. It is true that methanol is poisonous. If people drink methanol, it will cause great harm, including blindness and even death.

But now, except for some shady liquor manufacturers, it is estimated that no one will give methanol to people to drink, and normal people will not drink methanol.

"People can smell methanol when the concentration in the air is greater than 50ppm. To be harmful to the human body, the concentration must be above 200ppm. So the toxicity of methanol is not a problem. Methanol is swollen, and methanol alone has a higher swelling capacity than gasoline.

About 8%, which means that the life of the oil pipe is reduced by more than 8%. This can be solved through regular inspection and replacement. The so-called corrosiveness of methanol, pure methanol has obvious corrosion to lead, but not to other metals. There are reports that it is corrosive to other metals.

Aluminum is corrosive. Research shows that when the temperature is lower than 70 degrees, the corrosion is not too obvious. For other metals, the corrosion can be ignored when there is no electricity. Of course, this is about purity. The methanol we use is not

It may be very pure. At present, from the perspective of the fuel for producing methanol, it can be divided into coal-based methanol, natural gas methanol, and combined alcohol. Other combined alcohols are co-produced by-products in fertilizer plants, and the acid value and colloid contained in them are difficult to reduce.

It is these acids and colloids that are harmful to the engine. What we are talking about here is pure methanol. In actual use, methanol will absorb water vapor in the air, and this water will corrode iron products. This requires us to

We should work hard on the sealing of the engine and oil lines so that when methanol fuel is used, try not to come into contact with external metal. This requires the use of fluorine rubber, which can completely solve the so-called methanol corrosion problem. As for emulsions

, you can also use fluororubber for sealing to avoid contact between methanol gasoline, other colloids and water. Moreover, using fluororubber as the oil pipe material can avoid swelling and corrosive problems, and regular inspections can also eliminate this.

The problem."

Director Wan and Liu Yonghao were very satisfied with Jin Xiaoqiang’s questions about the emulsions produced by methanol fuel and the corrosion of the engine. Indeed, Jin Xiaoqiang’s words were very honest. He said this in simple terms about such a profound issue:

These two people now have a rough idea.

If you want to vigorously promote methanol fuel, you must give market consumers confidence, and if you want consumers to have confidence, you must start with technology.

It seems that Jin Xiaoqiang was not completely bragging before. He does have his own way of solving difficult and complicated diseases.

“So what about the poisonous nature of methanol gasoline?”

Director Wan asked again, but he did not say it explicitly. He knew that Jin Xiaoqiang must know more about this than himself.

"In 2003, the Chinese Academy of Engineering organized and took the lead in producing a report on "China's Sustainable Development of Oil and Gas Resources Strategy", which raised the issue of methanol gasoline, including swelling, toxicity and corrosion.

Sexual issues. The focus is on the toxicity of methanol gasoline. Here I will explain it. It is true that methanol is toxic, but the reason why methanol gasoline is considered toxic has nothing to do with the toxicity of methanol itself.

This is because methanol gasoline will produce formaldehyde due to insufficient combustion in the engine. Because of insufficient combustion, the formaldehyde produced is 3-6 times higher than the formaldehyde emitted by ordinary gasoline. This is what the Institute of Engineering emphasizes.

Toxicity issue. Our ordinary consumers have a misunderstanding here. They think that as long as they use the gas emitted from methanol fuel, or inhale too much of this gas, they will be poisoned. In fact, this is wrong. As long as we can solve this problem

The problem of complete combustion of methanol fuel and the problem of toxicity no longer exist."

Jin Xiaoqiang's words were clear and logical, and Liu Yonghao and Director Wan nodded frequently. It was obvious that Jin Xiaoqiang was on to something.

"The impact of methanol gasoline on the engine is that after methanol is injected into the engine, if it is not ignited, it will be mixed with the lubricating oil. The lubricating oil's lubrication effect will be greatly reduced until the engine temperature does not exceed 70 degrees, thereby increasing engine wear.

.In addition, if the fuel injection amount is not controlled properly, such as the injection amount is too large, the incompletely burned methanol will enter the exhaust pipe with the exhaust gas, part of it will be burned on the surface of the high-temperature oxygen sensor, and part of it will enter the three-way catalytic converter; 1.

On the one hand, it causes the oxygen sensor and three-way catalytic converter to fail faster. On the other hand, unburned methanol generates formaldehyde at high temperatures, causing emissions to seriously exceed the standard. That is to say, some drivers say it chokes the nose. Normally, there is only a slight emission in front of the exhaust pipe.

Smell. Such a problem mainly lies in the control of the fuel injection amount by the driving computer ECU, because the previous data settings of this ECU were specifically for gasoline injection and not for methanol gasoline injection, and methanol fuel is due to heat

It is relatively lower than gasoline, so the ECU will use its judgment to extend the time of fuel injection or increase the pressure of the oil pump, causing too much methanol gasoline to be injected into the cylinder, resulting in insufficient combustion. In the end, a lot of fuel is actually wasted, and then

Directly discharged from the engine, this will cause corrosion of auto parts, and on the other hand, it will cause the problem of excessive formaldehyde emissions. And we at Huayang Power have actually been working hard in this area..."

When Jin Xiaoqiang said this, Liu Yonghao and Director Wan's faces were already glowing. Methanol gasoline is indeed facing the three problems mentioned by Jin Xiaoqiang before, and these three difficulties have always been the biggest worries that have troubled them.

Swelling, corrosiveness to the engine, and toxicity. If Huayang Power can really solve these problems perfectly, then there is hope for the widespread promotion of methanol fuel across the country.

This is a great achievement for Liu Yonghao and Director Wan, and it is definitely a good thing.

In fact, the solution Jin Xiaoqiang mentioned is the methanol fuel converter that was once very popular in later generations, that is, installing an ECU system on the car. When the car uses methanol fuel, it will

This system controls the injection of methanol gasoline so that the methanol gasoline in the cylinder can be fully burned without being wasted and producing exhaust gas that corrodes the car and poisonous gas that is harmful to the human body.

This kind of sub-ECU fuel injection device has been popular in China for a period of time in later generations. Some consumers who had headaches because of fuel prices once used this device to modify their cars, but the effect was not very satisfactory. In the end, because

If the market performance is correct, this device will disappear.

In fact, the main reason is that it is just an ECU system. Although it can control the injection problem of methanol fuel and allow the methanol fuel to be fully burned, it does not control the fuel consumption of the entire vehicle like the current Huayang Power.

The road also has sealing devices for optimization, so it can only solve the problems of combustion and emissions. Regarding the swelling and corrosive problems of methanol gasoline that Huayang Power has solved, they do not have any good solutions.

.

It is precisely because of their incompleteness that they have failed to succeed in the market, and because the companies that manufacture this kind of ECU are generally not large formal companies, they have limited knowledge of various comprehensive data about the car.

The data entry of their ECU was not very sufficient. Even if this device was installed, it might not be able to accurately control the injection of methanol gasoline, so in the end they could only end up in despair.

But what kind of company is Huayang Dynamics? It is now the number one player in China's automobile manufacturing industry. In the field of ECU R&D and manufacturing, it is a company that cooperates with Delphi and Bosch. They have accumulated a lot of money in their own hands.

With data, coupled with the databases open to them by Delphi and Bosch, it was easy for them to study this ECU that controls methanol fuel injection. It only took a few months for them to figure out this ECU.

"Minister Liu, Director Wan, you see, these are the ECUs we have specially prepared for methanol gasoline. They are suitable for different models from 1.5l to 2.4l, and this one is specially prepared for large buses and passenger cars.

With this ECU system, if it is used with M85-specification methanol gasoline, then we can smoothly solve the problems of methanol gasoline, difficulty in starting the car in winter, as well as emissions and toxicity problems. In addition, we have strict requirements on methanol fuel vehicles.

By optimizing the engine and fuel lines, we can solve a series of problems such as swelling and corrosion caused by methanol gasoline. Although we still need regular maintenance and replacement of parts to ensure the normal operation of the vehicle, if

If we calculate based on the ultimate usage of the car of 400,000 kilometers, then if we use methanol gasoline, we can save 128,000 yuan on fuel, and the carbon monoxide emissions of methanol gasoline will be 30% lower than that of gasoline.

Nine, hydrocarbon emissions would fall by forty-seven..."

Liu Yonghao and Director Wan were completely shocked by the wonderful prospects described by Jin Xiaoqiang. If methanol gasoline could be promoted on a large scale, it would definitely be a great achievement!

"Minister Liu, Director Wan, over there are several pure methanol gasoline vehicles we have developed, including small cars and several large buses. Should we go over and take a look?"

Jin Xiaoqiang smiled and said to the two bosses that they had already prepared the car and were waiting for the right opportunity to push it out.

"Come on, hurry up, go over and take a look, haha, I can't wait..."

Director Wan took the lead, followed closely by Liu Yonghao. It seems that these two are more anxious than Jin Xiaoqiang...
