Another problem with methanol fuel is the legendary toxic problem, methanol is indeed toxic, if people drink methanol, it will cause great harm, blindness, and even death.

Now except for some black-hearted liquor manufacturers, it is estimated that no one will bring methanol to people to drink, and normal people will not drink methanol.

"People can smell methanol when the concentration is greater than 50 ppm in the air, and to be harmful to the human body, the concentration should be more than 200 ppm. So the toxicity of methanol is not a problem. Methanol is swollen, and the swelling of methanol alone is about 8% compared with gasoline, which means that the life of the oil pipe is reduced by more than 8%. This can be solved by regular inspection and replacement, the so-called corrosiveness of methanol, pure methanol is not obvious to other metals except for lead corrosion. Corrosiveness to aluminum has been reported, and studies have shown that corrosion is not too noticeable at temperatures below 70 degrees. For other metals without electricity, corrosion is negligible. Of course, this is talking about purity, the methanol we use cannot be very pure, at present, from the perspective of the fuel used to produce methanol, it can be divided into coal-to-methanol, natural gas methanol, and hydranol. It is difficult to reduce the acid value and gum content of other co-production by-products of the fertilizer plant. It is these acids and gums that are harmful to the engine. In this regard, we are talking about pure methanol, which in practice absorbs water vapor from the air, which corrodes the products of iron products. This requires us to work the sealing of the engine and the oil circuit, so that the methanol fuel can be used. Try not to come into contact with the outside metal, which requires the use of fluoroelastomers, which can completely solve the so-called methanol corrosion problem. As for the emulsion, it can also be sealed by using fluoroelastomer to avoid contact with methanol gasoline and other gums and water. In addition, if fluoroelastomer is used as the tubing material, the problem of swelling and corrosion can be avoided, and such problems can also be eliminated by regular inspection. ”

Director Wan and Liu Yonghao were very satisfied with Jin Xiaoqiang's problem with the emulsion produced by methanol fuel, as well as the problem of corroding the engine.

Want to promote methanol fuel. It is necessary to give confidence to consumers in the market, and if you want to make consumers confident, then you must start from the technical point of view.

It seems that Jin Xiaoqiang was not completely bragging before, and he did have his own set of solutions to incurable diseases.

"And what about the toxicity of methanol gasoline?"

Director Wan asked again, he didn't say it explicitly, he knew that Jin Xiaoqiang must know more than he did.

"In 2003, the Chinese Academy of Engineering took the lead. I made a report on the "Strategic Research on Sustainable Development of Oil and Gas Resources in the Celestial Empire", which mentioned the problem of methanol gasoline, including the problems of swelling, toxicity and corrosiveness. One of the key concerns is the toxicity of methanol gasoline, which I am explaining here. Methanol is toxic, but the reason why methanol gasoline is considered toxic is not much related to the toxicity of methanol itself, but because methanol gasoline will produce formaldehyde because of insufficient combustion in the engine, and because of insufficient combustion, the formaldehyde produced is 3-6 times higher than the formaldehyde emitted by ordinary gasoline, which is the toxicity of methanol gasoline emphasized by the engineering institute. And our ordinary consumers here have a misunderstanding, they think that as long as the gas emitted by methanol fuel, or inhale too much of this gas, it will be poisoned, in fact, this is not right, as long as we can solve the problem of full combustion of methanol fuel, this toxicity problem, there is no such thing. ”

Jin Xiaoqiang said the first thing, Liu Yonghao and Director Wan also nodded frequently when they heard it, obviously Jin Xiaoqiang said the point. …,

"The effect of methanol gasoline on the engine is that after the methanol is injected into the engine, if it is not ignited, it will be mixed with the lubricating oil, and the lubricating oil will greatly reduce the lubrication effect before the engine temperature is not higher than 70 degrees, thereby increasing the wear of the engine. In addition, if the amount of fuel injection is not properly controlled, such as the injection amount is too large, the methanol that is not completely burned 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; On the one hand, it causes the failure of the oxygen sensor and the three-way catalytic converter to accelerate, and on the other hand, the unburned methanol generates formaldehyde at high temperatures, which seriously exceeds the emission standard. That is, there is a driver who says that he chokes his nose, and normally there is only a slight smell in front of the exhaust pipe. This kind of problem mainly lies in the ECU of the driving computer, for the control of the amount of fuel injection, because the data settings of the previous ECU are specifically for gasoline injection, and not for methanol gasoline injection, and methanol fuel because the heat is relatively lower than that of gasoline, so the ECU will judge that when the fuel is injected, the time is extended, or the pressure of the oil pump is increased, resulting in too much methanol gasoline injection into the cylinder, resulting in insufficient combustion, and finally a lot of fuel is actually wasted, and then directly discharged out of the engineIn this way, it will be illuminated as corrosion of auto parts, and on the other hand, it will be illuminated as the problem of excessive formaldehyde emissions. And we, Huayang Power, have actually been working hard in this regard......"

Jin Xiaoqiang said here, Liu Yonghao and Director Wan are full of red faces, methanol gasoline is indeed facing the three problems mentioned by Jin Xiaoqiang before, and these three difficulties have always been the biggest worries that plague them.

Swelling, corrosiveness to the engine, and the problem of toxicity, if Huayang Power can solve these problems perfectly, then methanol fuel will be widely promoted throughout the country.

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

In fact, the solution that Jin Xiaoqiang said is the kind of methanol fuel converter that was once very popular in later generations, that is, a set of ECU system is installed on the car, when the car is using methanol fuel, this system will control the injection of methanol gasoline, so that the methanol gasoline in the cylinder can be fully burned without being wasted, and produce exhaust gases that corrode the car and toxic gases that are 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, and some consumers who have a headache for fuel prices have used this set of things to modify their cars, but the effect is not ideal, and finally because the market performance is not fake, this device has disappeared.

In fact, the main reason is that he is just a set of ECU system, although it can control the injection of methanol fuel, so that the methanol fuel is fully combusted, but he is not like the current Huayang Power, the oil circuit and sealing device of the whole car, optimized, so he can only solve the problem of combustion and emission, for the swelling of methanol gasoline solved by Huayang Power, as well as the corrosive problem, they do not have a good solution.

It is precisely because they are not comprehensive that they have not been able to succeed in the market, and because the companies that produce and manufacture this kind of ECU are generally not large-scale formal enterprises, they have limited grasp of various comprehensive data of automobiles, and their data entry of this ECU is not too sufficient, even if this device is installed, it may not be able to accurately control the injection of methanol gasoline, so in the end they can only end up drinking.

But what kind of company is Huayang Power, people are now the number one leader in the automobile manufacturing industry of the Celestial Empire, in the field of ECU research and development and manufacturing, it is a cooperative enterprise with Delphi and Bosch, they have accumulated a lot of data in their own hands, plus Delphi and Bosch, the database open to them, they study this is the ECU controlled by methanol fuel injection, it is simply easy, it only took a few months of effort, they got this ECU. …,

"Minister Liu, Director Wan, you see this is the ECU we have specially prepared for methanol gasoline, they are suitable for different models from 1.5L to 2.4L, and this is specially prepared for large buses and buses. With this ECU system, if it is matched with M85 methanol gasoline, then we can smoothly solve the problems of methanol gasoline, difficult to start in winter, as well as emission and toxicity, plus we optimize the engine and fuel line pipe of methanol fuel vehicles, we can solve a series of problems such as swelling and corrosiveness caused by methanol gasoline. Although we still need regular maintenance and replacement of parts to ensure the normal operation of the vehicle, if we calculate according to the ultimate journey of 400,000 kilometers of the car, then if we use methanol gasoline, we can save 128,000 yuan on fuel, and the carbon monoxide emissions of methanol gasoline will be reduced by 39% compared with gasoline, and the emissions of hydrocarbons will be reduced by 47......"

Liu Yonghao and Director Wan were completely shocked by the wonderful prospect depicted by Jin Xiaoqiang at this time, if this methanol gasoline can be promoted on a large scale, this seems to be a great achievement!

"Minister Liu, Director Wan, there are several pure methanol gasoline cars that we have developed, there are small cars, and a few large buses, should we go over and take a look?"

Jin Xiaoqiang said to the two bigwigs with a smile, in fact, they have already prepared the car, and they are waiting for the right opportunity to push it out.

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

Director Wan took the lead, and Liu Yonghao followed, it seems that these two are more anxious than Jin Xiaoqiang...... (To be continued)
