What is the best methanol for cars What is methanol for cars?

Have you checked the cylinder pressure and oil pressure? The use of methanol has high requirements for engine cylinder pressure and oil pressure, and many cars that use gasoline normally cannot use methanol well because of these two points.

Also, learn about the problems with using methanol and the solutions that are currently available.

Current Problems:

1, the current commonly used installation controller uses the original car fuel tank to burn pure methanol, due to the electrochemical action of methanol, the life of the original car oil pump will be greatly shortened, and similarly, the fuel level sensor of some models will also fail in a short time.

2. Because methanol is a strong solvent, the adhesive in the gasoline filter used in most automobiles will be dissolved and swollen by methanol, resulting in the failure of the filter element and the blockage of the fuel injector.

3. More importantly, the water vapor produced after methanol combustion is much more than that of gasoline, and a trace amount of formic acid is generated, which does not have much impact on the normal operation of the engine, but when it is stopped at night, it will adhere to the cylinder and valve position with the water vapor, causing trace corrosion, and this process will be manifested in about 1 year. At this time, a significant drop in engine cylinder pressure was measured. And it is that the longer the car is parked, the more obvious it is.

4. On the other hand, the heat of gasification and the flash point of methanol are much higher than that of gasoline, which will cause the temperature to be lower than 22 degrees (the critical temperature of the engine wear increased due to the actual test), the methanol injected into the engine fails to fully burn due to the low temperature of the cylinder wall, and this part of the unburned methanol will cause the performance of the lubricating oil to decrease during the period when the temperature is lower than 76 degrees, thereby causing the engine wear to increase, in addition, because the failure of the oil pump is not predictable, the failure of the oil pump will cause the engine to stop when driving for a long time. It has a serious impact on driving safety.

The above problems can only be solved in an effective way.

Solution: The methanol oil circuit is independent from the gasoline oil circuit of the original vehicle. The methanol oil circuit uses special rubber and metal filter elements, and uses a special methanol pump and a special pressure regulating valve to complete the low-temperature gasoline hot car under the control of the control system, and the engine temperature rises after automatically switching to the methanol oil circuit to work, the most important thing is to pay attention to the use, no matter which control system, it is impossible to know when you need to stop for a long time, and it is impossible to automatically switch to gasoline mode to drive out the water vapor in the engine and the trace amount of formic acid that may be formed, and it is impossible to avoid the impact of the third point above.

Because it does not change the nature of the use of the gasoline tank of the original car, there is no need to worry about the damage of the gasoline part of the original car; At the same time, due to the existence of dual oil circuits, the driver does not need to worry about engine breakdown due to oil circuit failure, and the perfect system design should be able to automatically switch to the original car gasoline state when the control system fails or even completely loses power. Ensure driving safety.

The above research results were provided by Rocket Man 8. The complete solution of dual set has successfully won the national invention patent.

It is not good to burn methanol in any car, the technology is immature, the corrosion of rubber components is large, and the oil pump is easy to break.

Methanol is commonly known as "wood alcohol" or "wood spirit", methanol instead of petroleum fuel has been used in foreign countries for many years, methanol vehicle control system technology has been very mature, the same as ethanol, methanol calorific value is low, but octane number is high, also oxygen, combustion methanol also needs to use a special engine. However, unlike ethanol, methanol itself is toxic.

It has a corrosive effect on non-ferrous metals and a swelling effect on rubber parts, so it is necessary to design the engine and the fuel transmission and distribution system on the vehicle. This type of car that is specifically designed to burn methanol fuel is called a methanol car.

Methanol cars also have the problem of cold starting, so methanol is mostly used in cars in the form of mixing with gasoline. The most common is M85, which is a mixture of 85% methanol and 15% gasoline.

In some parts of China, methanol gasoline containing 15% methanol is now being demonstrated, which contains a co-solvent that is miscible with gasoline, as well as a corrosion inhibitor that inhibits metal corrosion, and can be used in gasoline engines without any modifications.

Because methanol is toxic, special attention should be paid to all aspects of methanol use, and corresponding management systems and methods should be formulated to ensure the safety of use.

A methanol car is a vehicle that uses methanol instead of petroleum fuel.

Methanol car is a car with methanol as the main fuel, and can also be fueled by gasoline or gasoline-methanol mixed fuel, which is a new type of car with energy-saving and environmental protection technology content that is flexibly converted from methanol-gasoline fuel, and can also be modified from ordinary cars.

Modification method: ordinary cars to be modified into methanol cars, need to install methanol gasoline flexible fuel converter between the car fuel injector and the original car computer, play the role of adjusting the amount of fuel injection, so that the operating parameters of the original car can be changed, so that the gasoline engine can burn methanol fuel.

Flexible fuel converters, some are single-parameter, there are also multi-parameter adjustable, the most common methanol gasoline converter is the 4-speed fuel adjustable methanol converter, which has 4 fuel parameters to choose from, can adapt to the operation of the vast majority of vehicles, compared with the controller with a single parameter, the advantages are more obvious.

1. Methanol car is a vehicle with methanol as the main fuel, and can also be fueled by gasoline or gasoline and methanol mixed fuel, which is a new type of car with energy-saving and environmental protection technology content that can be flexibly converted from methanol and gasoline fuel, and can also be modified from ordinary cars;

2. Methanol gasoline refers to a new type of ring stool Huaibao clean fuel that is blended with gasoline, methanol and additives according to a certain volume or mass ratio through a strict process, which is an excellent alternative fuel for vehicles and an important part of new energy;

3. The combustion characteristics of methanol have two major characteristics, one is the cooling effect of Lu Youjia, and the other is the extremely high anti-explosion ability, the advantage of methanol is that it burns thoroughly, has low volatility, and emits less harmful gases such as hydrocarbons, nitrogen oxide and carbon monoxide.

Nowadays, many regions of our country have not yet fully popularized charging piles, and the planning and layout of methanol filling stations is a very big challenge.

Some advantages of methanol vehicles: because methanol is very extensive, whether it is coal, wood or minerals can be refined methanol, so its social comprehensive cost is low, rich, and the acquisition cost is low, which can greatly reduce the production cost of automobiles, and at the same time reduce its selling price, which is relatively economical for consumers; At the same time, methanol vehicles are relatively powerful, burn thoroughly, and have relatively clean emissions.

While methanol vehicles bring benefits to consumers, there are also corresponding drawbacks, such as:

1.The calorific value of methanol is low, although the combustion can be complete, but the energy provided is not enough, when the car needs to be strongly propulsed, the consequent consumption will increase, and the overall economy is not strong.

2.The adaptability of methanol is relatively poor, especially in a low temperature environment, it is difficult to start the car, especially in winter, which will bring a lot of trouble.

3.Methanol is a volatile liquid, and flammable and explosive, as the main fuel of automobiles, the safety hazard is very large, may be a slight collision brought by the spark will cause deflagration, from the safety considerations, methanol will not be vigorously promoted as a car fuel.
